Flat Roof Insulation Systems

The basic decision to make when it comes to thermal insulation of a flat roof is the material.

Flat roof insulation systems.

While insulation for a flat roof is expensive and can account for as much as 25 of the total installation cost there are a number of important benefits to having it in place. Extreme s pre insulated sips offer an option for a high performance roof framing solution that is 15 times tighter than conventional construction practices making it easier to control indoor air environment. Build for the future with extreme s structural insulated panels sips the high thermal values and strength properties of extreme s sips are highly beneficial for roof construction. A bottom layer or two of insulation board multiple intermediate layers of tar or asphalt alternated with layers of roofing felt and a top layer of gravel.

Flat expanded polystryene eps roof insulation provides high long term r value of eps and labor saving face laminates. And it s worth saying that a well detailed flat roof particularly protected with ballast and or a green roof assembly can last longer than a pitched. Consider geography budget and use for the roof to determine the best option. Flat roof insulation what does it depend on.

Why its important to insulate your flat roof. As an example ikotherm insulation and cover boards are dimensionally stable and compatible with a variety of roofing systems. Bur consists of many layers. Powerdeck f a flat roof insulation board for use in built up felt and single ply membrane waterproofing systems.

It s the holes and gaps e g. Rockwool stone wool roof insulation combines the thermal performance dimensional stability impact resistance and acoustic control required to increase the performance of many flat roof assemblies. A note to consider before construction. If insulation is installed below the flat roof deck this is called a cold roof.

From there the flat roof system you choose will determine the materials you apply. Built up roofing bur was the most common type of flat roof before modified bitumen and membrane roofing were developed. Reduce extreme temperature fluctuations inside your home. Most hybrid systems foam board plus blown in serve adequately.

Recessed cans mechanical systems or just plain poorly punchlisted construction that kill you. Rockwool products are available with a bitumen or mineral coated fiberglass face to be used in a number of roofing solutions. The one you finally choose depends on several factors such as the arrangement of the layers of particular materials the way the roof slope is used and the type of roof.
