Warm concrete roof.
Inverted roofs have their waterproofing layer beneath the insulation instead of above it as in other forms of roofing.
Warm roof insulation ensures the entire roof structure is insulated meaning a warm deck roof is more energy efficient than a cold roof.
The insulation is immediately below the waterproofing layer.
In this issue the investigations team explains how inverted roofs work outlines their benefits warns of a possible cause of problems and describes an unusual investigation.

For example the florida based company hurricane proof systems offers a 7 inch 18 centimeter slab of concrete in three layers.
To insulate a flat roof with a concrete deck we recommend a warm deck construction method where the vapour control layer is sandwiched between the concrete deck and a layer of rigid pir insulation boards.
The thermal efficiency isn t as good as with warm roof.
The concrete deck can offer greater speed of roof construction which is an important consideration on many larger commercial projects.
In america modern concrete homes are becoming very very popular.
A solid slab of concrete capping the top of your house.
This makes a lot of sense especially since according to chemistry world magazine concrete is the most widely used building material in the world.
This keeps the structural decking usually constructed from timber steel or concrete at the same temperature levels as the internal temperature of the building.
You can either use removable concrete forms or forms that are made of concrete and insulate the house.
The breakdown warm roof vs cold roof.
In warm roof construction the thermal insulation layer is installed above the structural deck.
The vapour control layer is above the decking but below the insulation.
This video will demonstrate how to install a cure it grp waterproofing system in a warm roof build up.
A concrete roof is exactly what it sounds like.
Exact specifications vary but most concrete roofs are several inches thick.
The insulation can be adhered mechanically fixed or loose laid.
There are two ways to make a framework for a flat concrete roof.
A cold flat roof insulation requires more work taking off old boards and replacing them and the roof surface.
