Утеплитель с фольгой какой стороной укладывать: Какой стороной правильно уложить фольгированный утеплитель

Как правильно положить утеплитель фольгированный – секреты монтажа, характеристики

Монтаж утеплителя фольгированного

Фольгированный утеплитель имеет достаточно широкий спектр применения, используется для изоляции труб с холодной и горячей водой, для утепления стен, в качестве подложки при укладке паркета или под ламинат, для утепления ульев, звукоизоляции помещения, кровельных работ, утепление вентканалов, теплоизоляция промышленного оборудования.

Таким утеплителем обшиваются стены изнутри помещения за батареями для сокращения теплопотерь, поскольку он термостойкий . На нашем рынке представлены следующие торговые марки: Алюфом, Урса, Пенофол, Фольгоизол, Изолон, Кнауф, Лавсан, Магнел, Мегафлекс, Пеноплекс, Экотеплин, наиболее популярный вид это с фольгой и вспененным поролоном.

Сколько стоит данный материал? Все зависит от производителя, которому вы отдадите предпочтение, цена колеблется от 1 до 4 $ за метр2. Давайте попробуем более подробно рассмотреть как правильно положить данный материал на различные поверхности.

На стену

Зачастую стены утепляют подобным материалом в банях, саунах, на балконах, в этом случае используется материал на полиэтиленовой основе. Рекомендуется использовать утеплитель толщиной не менее 10 мм, подобный материал бывает покрыт фольгой как с одной стороны, так и двухсторонний.

Если рассматривать варианты, на что его можно прикрепить, лучше всего подойдет строительный степлер, двухсторонний скотч, также можно использовать специальный клей на каучуковой основе, места стыковки листа проклеивают скотчем. Если речь идет об утеплении балкона, тогда нужно укладывать дополнительный теплоизоляционный слой, например, пенопласт, базальтовый материал или другое.

Можно ли утеплить без них? Конечно, да, однако вы не получите желаемого результата. Для того, чтобы утеплитель выполнял поставленную перед ним задачу, необходимо разобраться, как правильно класть его. Расстояние между материалом и обшивкой должно быть приблизительно 20 мм, это позволит создать некую воздушную прослойку, которая будет служить воздушным барьером.

Рассмотрим в деталях, как правильно крепить к стене:

• Прикрепите пенопласт к заранее подготовленной поверхности.
• Поверх него закрепите утеплитель фольгированный.
• Затем поверх произведите монтаж деревянных брусков, далее зашейте все выбранным материалом (гипс, сайдинг), места стыков зашейте фольгированным скотчем.

На потолок

Как правило, на потолок выбирается максимальная толщина утеплителя, поскольку все тепло поднимается вверх, и там происходят его максимальные потери. Благодаря своей отражающей поверхности утеплитель способен отразить до 90% тепла, таким образом, повышает общую эффективность изоляционной системы на 60 %. Данные характеристики будут можно получить при условии соблюдения правил установки.

Для проведения работы вам понадобится следующее:

• Степлер строительный.
• Небольшие гвозди.
• Молоток.
• Утеплительный материал.
• Алюминиевый скотч.

Такое изделие продается в рулонах, для удобства монтажа разрежьте его на нужные отрезки. А какой же стороной его укладывать? Монтаж нужно делать так, чтобы фольгированная поверхность была внутри помещения (серебряной стороной к вам). Итак, давайте разберемся, как прибить данный материал.

Зазор между отделочным материалом и утеплителем должен составлять порядка 20 мм, эта буферная зона обеспечивает защиту помещения от потери тепла.

Во время крепления на потолок закрепите его, используя степлер, крепление должно быть стык в стык, а монтажные швы проклейте алюминиевым скотчем, для обеспечения гидро- и теплоизоляции.

На пол

Пожалуй, процесс установки на пол наиболее трудоемкий, и существует больше возможных вариаций, поскольку можно стелить под линолеум, паркет, ламинат, систему теплый пол (не только водяной пол). Все это возможно, благодаря его негорючей основе, так как с одной стороны имеется отражающая фольга, а с другой поролон.

У некоторых производителей есть вариации, где с двух сторон поролон. Итак, опишем более детально процесс монтажа пола из дерева. Для этого нам понадобится следующее: строительный нож, утеплитель, алюминиевый скотч, метр, машинка для шлифовки, грунтовка антисептик, шпаклевка.

Для данного вида работ лучше отдать предпочтение материалу с клейкой основой, однако, можно выйти из положения, имея двухсторонний скотч.

Порядок выполнения работ:

• Подготовьте основу, снимите плинтус, обработайте пол шлифовальной машинкой, если есть неровности, уберите их, используя шпаклевку.
• Обработайте антисептической жидкостью. После просыхания сделайте замеры и разрежьте на нужные куски. Постелите лист, внутри должен быть поролон, а снаружи фольга.
• Выполните герметизацию швов, используя металлизированную ленту.
• После чего уложите паркет, ламинат.

Если же вы выполняете утепление бетонного пола, технология схожа, однако, для проклейки лучше использовать специализированный каучуковый клей. А во всем остальном технология та же. Если у вас очень холодный пол, в подобном случае на утеплитель набиваются деревянные лаги, ниши в них заполняются утеплительным материалом, сверху зашивается листами ОСБ-плит, затем грунтуется и укладывается выбранный материал покрытия.

Разновидности материала

Давайте рассмотрим, как называются виды утеплителя:

• С вспененным полиэтиленом, имеет вид рулонного самоклеющегося материала, похож на пленку с фольгой. Сфера применения в различном оборудовании, обшивка труб, шахт, крыш, поскольку имеет высокотемпературный диапазон от -160 до +160 градусов, огнеустойчив.
• Минеральная вата с фольгированным покрытием, может иметь вид плиты, цилиндра. Также имеет высокую степень огнеустойчивости.
• Пенополистирол, с двух сторон обработан фольгой. Также имеет широкий температурный диапазон, в диаметре может быть 5мм, 10мм, 15 мм.
• Базальтовый, так же, как и вышеописанные материалы изготовлен на основе фольгированного материала, однако, благодаря уникальной технологии, может выдерживать температурные колебания от -200 +600 градусов, устойчив к агрессивным химическим средам.

Как класть утеплитель на трубы

Как правило, такой материал имеет вид трубного” кокона”, изготовленный из минваты (выдерживают высокие температуры) или пенополистирола (влагоустойчивые). А как утеплять их, вопрос отпадает сам по себе, поскольку они имеют вид “кокона”, который надевают поверх и фиксируют . Существуют магистральные, для дымоходов, различных диаметров и температурных режимов.

Однако, если вы решили приобрести листовой утеплитель, перед вами может стать вопрос, как его приклеить к металлу? На помощь вам придет алюминиевый скотч, который наматывается на утеплитель поверх трубы. И, как в вышеописанных вариантах, одевать необходимо блестящей стороной к себе.

Можно ли утеплить стены снаружи

Для утепления стен снаружи используется перфорированный утеплитель фольгированный. Это материал, обладающий помимо прочего звукоизоляционными качествами, способен оградить ваш дом от влаги и ветра, а также не препятствует выходу влаги из помещения. Этот вариант идеален для тех, у кого нет возможности выполнить подобные работы внутри помещения. Однако, подобные мероприятия можно выполнять только в теплое время года и в сухую погоду.

Для этого вам придется сделать следующее:

• Если у вас на стене было какое-либо покрытие, вам нужно избавится от него. После чего обработайте поверхность антисептическим раствором. Лучше это сделать в жаркую погоду, чтобы хорошо все просохло, особенно внимательно обработайте нижнюю часть здания. В течении двух дней поверхность полностью просохнет.
• Далее соорудите каркас из бруса, закрепите его при помощи саморезов. Уложите Пенафол, далее оставьте воздушный туннель, проклейте места стыков, далее монтируют наружный каркас.

90000 Do You Put the Shiny Side of Foil Insulation Up or Down on a Metal Roof? | Home Guides 90001 90002 By Chris Deziel Updated August 09, 2019 90003 90002 Foil insulation underlayment is recommended under a metal roof, and in most cases, the shiny side should be facing up, but there’s a catch. Foil insulation is a radiant barrier, and it works by reflecting heat from the metal, but for it to do its job, there has to be a layer of air between the roofing and the foil. Some types of metal roofing are shaped to create this air space, but if you’re installing a type that does not, you should construct a batten structure.The foil then goes under the battens. 90003 90002 For proper installation of roof insulation, you need to do it before the roofing goes on. If you want to add foil insulation to an existing roof, you can still do it by going into the attic and stapling it to the undersides of the roof rafters. If you do this, the shiny side of the insulation still goes up, and the rafters automatically create an air space between the insulation and the roofing. 90003 90008 The Reason Why You Need Foil Insulation 90009 90002 When sunlight impinges directly on a metal roof, it drives the temperature of the metal as high as 180 degrees Fahrenheit.In the absence of a foil insulation barrier, the underside of the roof radiates all the heat directly into the attic. The attic overheats, the house becomes warmer and your air conditioning bill goes through the roof. 90003 90002 The radiant foil barrier reflects all that heat back into the air space between it and the roofing. When foil insulation is properly installed, the underside of the roof decking 90013 remains at or near the ambient temperature, 90014 even in full sun. This does not work, though, if you install the radiant barrier upside down — that is, with the shiny side facing down.If you do that, the barrier absorbs the heat and radiates it into the attic instead of back toward the roof. 90003 90002 A radiant barrier can reduce the temperature in the attic by as much as 30 degrees. It also keeps attic-mounted air conditioning ducts cooler, which means more efficient and less costly operation of the air conditioning system. 90003 90018 Bubble Foil Insulation — Which Side Out? 90009 90002 Bubble foil insulation adds a layer of insulating air to the radiant barrier provided by the foil.This product, like sheet foil, should be installed with the 90013 foil side facing the metal roofing, 90014 but there is one qualifier. If the space you’re insulating is habitually too cold, you might want to turn the shiny side toward the living area to create more warmth. You would do this, for example, when insulating the walls of a finished basement. 90003 90002 Foam insulation board also comes with a foil backing, and when the foil is just on one side of the board, you have a decision to make regarding its orientation.If you’re wondering whether to put the foil side of foam insulation board shiny side in or out, consider whether you want to make the space inside warmer or cooler. If you want to make the space warmer, the foil should face inside so it can reflect radiant heat back into the room. 90003 90026 Proper Installation of Roof Insulation 90009 90002 When installing a new roof or redoing an existing one, the roof decking goes on first. This is followed by a moisture barrier, which is typically # 30 or heavier roofing felt or tar paper.The foil insulation goes on top of the moisture barrier, followed by the roof covering. If you use bubble foil or rigid foam insulation, it also goes on top of the moisture barrier. 90003 90002 Remember that 90013 there has to be an air space between the foil and the roofing. 90014 Most metal corrugated roofing automatically provides this air space. If the corrugations are such that only about 20 percent of the material is in contact with the roof, it’s fine to lay corrugated roofing directly on the foil.If you’re installing flat roofing or metal tiles, however, you need to construct a batten structure on top of the foil. 90003 90002 Roofers typically use one of a number of batten configurations. The battens can run parallel to the roof ridge or diagonally between the ridge and drip edge. To ensure that air can circulate, it’s important to leave a 2 to 3-inch gap between the ends of the batten boards. Some batten structures consist of two layers, one perpendicular to the ridge and the top layer parallel to it.In this type of double-layer structure, it’s permissible to lay the foil insulation between the layers. 90003 90036 DIY Roof Insulation 90009 90002 If you’re doing your own roof installation, you will not have any trouble installing a radiant barrier, but there are a few things you should remember. They will help you complete the job correctly and safely: 90003 90040 90041 Work on cloudy days or during times of the day when the roof is cool. 90042 90041 Carry all your tools with you to minimize the number of times you have to go up and down the ladder.90042 90041 Wear rubber-soled shoes and use a harness if necessary. Never work on a roof that feels too steep for comfort. Hire professional roofers instead. 90042 90041 Always have a helper to spot you in case something goes wrong. 90042 90049 90002 To install foil insulation, roll it out parallel to the ridge and cut it with a utility knife, starting at the drip edge and working your way up. Overlap seams by about 3 inches. Secure the barrier to the roof deck with staples to prevent it from blowing off until you attach the battens and the roofing.90003 90002 Foam insulation comes in sheets that you have to butt together on the roof. After securing these with appropriate fasteners, you need to tape the edges with foil tape. Tape is not necessary when installing foil insulation. 90003 90054 Insulating an Existing Roof 90009 90002 You can add insulation to an existing metal roof by going into the attic and 90013 stapling a foil barrier to the rafters. 90014 If the shiny side of the barrier faces the roofing, hot air will circulate in the space between the rafters and naturally exit through the roof vent.This scheme works best if the house has a ridge vent that spans the length of the roof. For other systems, it may be necessary to drill holes in the rafters to allow air to flow toward the vents. 90003 90002 Install the barrier by stretching it across the rafters from one end of the attic to the other and stapling it to the rafter faces. Work from the ridge toward the wall plates, overlapping the sheets by 2 inches and being careful not to cover soffit vents, light fixtures or switches. 90003 90002 An alternative to attaching the foil to the rafters is to 90013 lay it on the attic floor with the shiny side facing up.90014 This will make the attic warmer, but it will keep 97 percent of the heat radiating through the roof from coming into the house. If you have ducts in the attic, you can prevent them from overheating by covering them with the same radiant barrier. One disadvantage of this insulation method is that it promotes condensation between the insulation and the floor. To control this, you may have to roll back the insulation periodically to allow the floor to dry out. 90003.90000 Aluminum Foil: Should the Shiny Side be Up or Down When Cooking? 90001 90002 Since aluminum foil has a shiny side and a dull side, many cooking resources say that when cooking foods wrapped or covered with aluminum foil, the shiny side should be down, facing the food, and the dull side up. This is because the shiny side is more reflective and so will reflect more of the radiant heat than the duller side. 90003 90002 Is this true? 90003 90002 Although most resources still say it is true, the shiny side should be down, some newer sources say that it makes no difference which side of the aluminum foil faces up.90003 90002 For example, Robert L. Wolke in What Einstein Told His Cook and America’s Test Kitchen say that it makes no difference at all in cooking. You can place either side in either direction whether cooking or freezing food with aluminum foil. 90003 Leifheit 4-in-1 Wall-Mount Paper Towel Holder | Plastic Wrap and Foil Dispenser with Spice Rack 90002 However, their explanations make little sense. They are in effect pseudo-explanations. 90003 90002 Both sources provide the following, similar explanation (paraphrased): 90003 90014 90002 Aluminum foil has a shiny side and a dull side.Many people believe that it matters which side is used up or down. The truth is that it makes no difference at all. The reason the two sides look different is due to the manufacturing process. When the sheets of aluminum are rolled out, the side that comes in contact with the rollers come out shiny .. 90003 90017 90002 This explanation does not explain why the shiny side makes no difference. It simply reiterates, with a bit more explanation, that foil does, in fact, have a shiny side and a dull side.Not very informative! 90003 90002 Regardless of why one side of aluminum foil is shiny and one is dull, it stands to reason that the shinier surface will be more reflective than the duller surface. The explanations given seem to indicate that since the shiny and dull sides are simply a by-product of the manufacturing process and are not purposely put there, they make no difference. The explanation does not support the claim. So what’s the truth? 90003 90002 The truth is that the shiny side of aluminum foil is only a little bit shinier than the dull side.While some small amount of additional energy will be reflected by the shiny side, the difference is so small that it will make no practical difference in cooking. To say that there is no effect whatsoever is inaccurate and it probably still is a little more efficient to cook with the dull side out. However, when measured over time in high temperatures, the difference is so slight that there should be little discernable change in cooking times. This may seem like a lot of explanation to come to the same conclusion, but it is not my purpose to give inaccurate explanations! 90003 90002 90003 90026 Why Does not the Shiny Side of Aluminum Foil Make A Difference? 90027 90002 Yes, the shiny side is more reflective but reflective of what? 90003 90002 There are three basic ways heat can be transferred: conduction, convection, and radiation.Conduction is when heat is transferred through contact of one object with another hot object. This is what happens when we cook on the stove. 90003 90002 Convection is the transfer of heat by the physical movement of surrounding fluid (liquid or gas). Radiation is light waves, radio waves, microwaves, X-rays, etc. carrying heat energy from one surface to another. 90003 90002 Any object with a temperature above absolute zero emits infrared radiation. This means that the heated coils, sides, and racks in your oven are emitting infrared energy.Even the heated vessel and the heated food itself emits this energy. 90003 90002 However, when you cook food in an oven, the major source of cooking heat is convection. The hot air of the oven transfers heat to the food being cooked. Do not be confused by «convection ovens.» All ovens use convection, convection ovens just use a fan to make the convection more efficient. Only a little of the heat transfer in an oven is through infrared radiation, which is invisible light rays. 90003 90002 A shiny surface should 90039 make no difference 90040 to 90041 convection 90042 but it will 90039 make a difference 90040 to 90041 radiation 90042.Shiny surfaces reflect waves more than dull surfaces. The reason one side of the foil is more shiny than the other is because it is smoother and has less little imperfections: hills and valleys. So, the shiny surface of the foil should reflect more radiation than the dull surface, which will be better able to trap incoming waves rather than reflect them back. But it should not affect convection, the 90041 major source of heat transfer 90042. 90003 Aluminum foil: Shiny side and dull side. You can clearly see that the shiny side of the foil reflects more light (radiation) than the dull side.But, this should make little difference in a conventional oven, where the major source of heat transfer is convection 90002 Consider a baked potato. When wrapping potatoes in aluminum foil for baking, you probably tend to place the dull side out. In reality, in the long length of time it takes to bake a potato, either side will work basically the same. The foil will be heated through convection and this energy will be transferred to the potato, and as the moisture in the potato heats up, the potato is cooked through steam.90003 90002 Rather than which side is out, a bigger difference may be made by how tightly the potato is wrapped. Any air trapped in the aluminum foil pouch and surrounding the potato may act as an insulating barrier, slowing the transfer of heat. So, wrap your potatoes tightly before baking. 90003 90002 So, it is up to you which side of the aluminum foil goes up. 90003 90056 How is Aluminum Foil Made? 90057 90002 Since I already mentioned the manufacture of foil through the explanations given above, I may as well write a bit more about how foil is made.90003 90002 The manufacture of aluminum foil is similar to making pasta at home. A large block of almost pure aluminum is rolled through giant steel rollers, several times, reducing the thickness of the aluminum block and spreading it out to make it longer. Lubricants are added to facilitate the operation. At each successive pass through the rollers, the thickness is reduced. The process is repeated until foil thickness is reached, and the large flat sheet is then split into the desired widths.90003 90002 This may seem simple enough, but the actual process can be tricky. For example, as the aluminum is rolled out, it heats up. If it heats up too much, it can stick to the rollers, so the roller pressure must be carefully controlled. 90003 90002 Once the sheet of aluminum is 5mm thick, it must be rolled again in the cold-rolling stage. First, the sheet is spooled into a roll and then it is fed into the cold-rolling mill for the final stage of milling. It is at this point that the shiny and dull sides of the aluminum are created.Since the aluminum is now so thin, the tension needed to feed it through the cold rollers could easily break it. So, the sheet is doubled. The sides of the aluminum that come in contact with the steel rollers become more polished and shiny, and the sides of the aluminum that come in contact with itself become duller. 90003 90066 Tin Foil? 90067 90002 Foil is no longer made out of tin as it is more expensive and less durable than aluminum. However, the term tin foil is used for aluminum foil in many regions, including by some in the United States.The information on this page, then, applies to both aluminum foil and tin foil as both terms refer to the same product. 90003 90002 This article contains one or more Amazon affiliate links.

There is another- sometimes overlooked — category of insulation: foil. We know that foil makes a good insulator because of its very highly reflective properties, but does a thin layer of foil actually perform as well as a thick slab of insulation? Is there any way to get those ultra-low U-values ​​required of modern buildings without having a thick layer of rock wool? Let’s take a closer look.90004 90005 U-value of foil insulation 90006 90003 The U-value is a simple measure of how easily heat is able to pass through a material. Lower U-values ​​mean better thermal performance. Most brands of insulation have a U-value displayed on their products as a matter of pride. Typical fibreglass insulation, for example, requires 270mm of insulation to get to a U-value of 0.16. Phenolic board like Celotex or Kingspan requires 175mm or so to achieve 0.16. 90008 If you pick up a pack of foil insulation, the U-value is often not easy to find, if it’s there at all.So what is the U-value of foil? 90004 90010 90005 Radiation vs conduction 90006 90003 Regular insulation works by preventing the conduction of heat through the material. The insulation is tested in a lab to work out the conduction through the material, λ (lambda). This value can be used to work out the U-value for any given width of material. 90004 90003 This works well for most insulation materials, because conduction is the main way they prevent the movement of heat. Foil insulation works slightly differently, however.Whilst there will be some resistance to conduction, thanks to the air gaps between the layers of foil, most of the performance of the material lies in its ability to reflect radiative heat back into the room. This characteristic is not an important player when it comes to fibreglass or wool insulation, but is crucial for foil. 90004 90003 It means that foil insulation is going to have a higher U-value, but may well perform better than expected in the real world. There is not much unbiased data out there to give you on this, but some manufacturers have done real world tests comparing foil with standard insulation, with encouraging results.Obviously, it depends on the type of foil and the amount of layers present, but some evidence suggests a performance better than standard insulation at much reduced thicknesses. 90004 90005 Foil insulation is used by NASA, right? 90006 90003 Foil is used in space-faring craft because of these great properties preventing radiant heat loss. Because space is a vacuum, there is very little heat lost by conduction, so foil is absolutely perfect. 90004 90005 How do I use foil insulation? 90006 90003 Foil insulation is worth considering if you have restricted space in your loft or roof space that means regular insulation is not viable.You will have to ensure there are good air gaps either side of the foil to get the best performance. We would recommend going for one with plenty of layers and some heft to it, as the thinner ones will not give a great performance. 90004 90003 90028 90004 90005 Building regulations and foil 90006 90003 You might wonder — if the U-value is not apparent — whether foil insulation can be used to meet building regulations requirements for insulation. The answer is that it is at the discretion of the planning authority, and each authority will probably treat things differently.Because foil insulation companies will provide their own energy saving data on their product, it is down to the individual planning authority as to whether it can be used and what thickness is required to meet the standard. 90004 90005 Should you use foil insulation? 90006 90003 We would probably recommend shying away from it unless it really is the most practical option, due to space constraints. In this case, speak to your architect and planning authority to find exactly what would be the most suitable thickness.90004 90038 90003 90040 90041 Think we missed something?

Most importantly, it helps to increase the thermal insulation value by reflecting heat from entering the home or building. In addition to being an effective radiant heat insulation, aluminium foil sarking has added acoustic benefits such that it dampens noise from rain falling on the roof and outside wind to create a quieter indoor space to enjoy.90003 90008 When To Install Aluminum Foil Insulation? 90009 90002 While foil insulation may only account for a small fraction of the total building cost, it is critical that you get it right and avoid the needless cost of having to re-do it at a later date. Essentially insulation boils down to selecting the right product, and ensuring it is properly installed at the right stage of the building project and preserved from damage until the completion of the building. Sisalation insulation and reflective roof sarking in particular, lose some of their effectiveness if the surface becomes covered in dust or grime, so the quicker the building exteriors are completed following the installation of the insulation, the better! Furthermore, if foil is in contact with other elements of the building it will conduct the heat energy to that surface, thus it is essential that foil insulation is installed with an air-gap.90003 90002 Read more 90003 90014 90015 90002 From $ 7.84 p / m2 90017 inc.

This helps keep you warmer in winter and cooler in summer. While bulk insulation works by slowing the heat transfer through the insulating material, foil insulation like Sisalation use their reflective surface to stop radiant heat.90003 90002 90003 90002 Contrary to what you might expect, insulation foil does not need to face its reflective foil surface outwards ‘towards the sun’ in order to work, and in fact (for safety / anti-glare reasons), it is much more commonly installed with the reflective surface facing into the house. When used in combination with bulk thermal insulation, Sisalation foil insulation is very effective both in increasing the thermal efficiency of the building, as a windbreak, and also can serve as a reassuring guarantee that the thermal wall batts will not come into contact with the brickwork.Without an air-gap of about 2cm, foil insulation will not work as it should, and with no air-gap, the product is basically ineffective as an insulator. 90003 90002 Fletcher’s Sisalation foil wraps come in 30m and 60m rolls, and when installed with an airgap, achieve an approximate R1.0 value. Some of our other popular foil insulation products include Knauf Earthwool Foil Faced Roofing Blanket and Kingspan Air-Cell Insulation. 90003 90002 90003 90004 Types of Aluminum Foil Insulation 90005 90002 90071 Reflective Foil Insulation 90072 90003 90002 Reflective foil insulation and breather wall wrap products provide a secondary protective skin for your home which can reduce draughts and help make you home more comfortable.Sisalation protects the building structure from the elements prior to the application of the external cladding and acts as a secondary protective layer against rain and dust after the construction has been completed. Roof sarking is also known to be used under older roofs, as a kind of insurance against leaks. While this may ‘do the job’ it is of course not the recommended solution to a damaged or leaking roof. Foil insulation can provide an additional R-value when installed within an air cavity in the building frame.90003 90002 90071 Roof Sarking and Foil Wrap 90072 90003 90002 Roof sarking is installed in homes to reduce summer heat gains and reduce cooling costs. Aluminium foil insulation is a highly reflective material that rebounds radiant heat rather than absorbing it. Reflective insulation together with thermal insulation batts are a perfect combination to optimize your homes R-value. Our preferred brand of foil wrap reflective insulation is Sisalation® by Fletcher. Sarking insulation for roofs can also assist in condensation control from water dripping down from the underside of metal roof sheets, and down into the ceiling area below.This is particularly a concern in tropical regions where condensation and humidity is likely to be an issue. 90003 90002 90071 Breather Wall Wrap 90072 90003 90002 Where air transfer from each side of the membrane is required and unclassified water barrier properties are acceptable, breather wall wrap products are considered to be the best option. Homes in cooler climates with a high insulation value run the risk of condensation problems in the construction. Breather insulation foils allow the construction to breath allowing possible condensation to escape and dry up.Contact us for advice regarding breather wall wrap products and their application. 90003 90002 90003 90004 Video — How Ordering Works 90005 90002 90093 90094 90003 .
