A note to consider before construction.
Flat roof insulation systems.
Flat expanded polystryene eps roof insulation provides high long term r value of eps and labor saving face laminates.
Built up roofing bur was the most common type of flat roof before modified bitumen and membrane roofing were developed.
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.
It s the holes and gaps e g.
While insulation is an important part of a roof system it can increase the probability of entrapping water within the roof assembly.
Reduce extreme temperature fluctuations inside your home.
Flat roof insulation what does it depend on.
Powerdeck f a flat roof insulation board for use in built up felt and single ply membrane waterproofing systems.
The basic decision to make when it comes to thermal insulation of a flat roof is the material.
Why its important to insulate your flat roof.
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.
Bur consists of many layers.
Rockwool products are available with a bitumen or mineral coated fiberglass face to be used in a number of roofing solutions.
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.
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.
If insulation is installed below the flat roof deck this is called a cold roof.
Consider geography budget and use for the roof to determine the best option.
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.
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.
Most hybrid systems foam board plus blown in serve adequately.
From there the flat roof system you choose will determine the materials you apply.
Recessed cans mechanical systems or just plain poorly punchlisted construction that kill you.
Flat expanded polystryene eps roof insulation is suitable for use with all roofing membrane materials flat eps roof insulation is compatible with loose laid and attached single ply membranes conventional built up roofing or modified bitumen systems.
