In warm roof construction the thermal insulation layer is installed above the structural deck.
Warm concrete roof.
The flat concrete roof itself can be up to 7 inches thick although the greater the thickness the more the concrete will need be poured in increasing numbers of layers with each.
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.
This video will demonstrate how to install a cure it grp waterproofing system in a warm roof build up.
Warm roof build ups can be installed on most modern construction material types such as concrete timber and timber based sheets.
A cold flat roof insulation requires more work taking off old boards and replacing them and the roof surface.
The insulation is immediately below the waterproofing layer.
Inverted roofs have their waterproofing layer beneath the insulation instead of above it as in other forms of roofing.
The vapour control layer is above the decking but below the insulation.
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.
This makes a lot of sense especially since according to chemistry world magazine concrete is the most widely used building material in the world.
They can be built up from profiled metal decks as the insulation selected would provide enough rigidity to span the open sections of such decks.
This keeps the structural decking usually constructed from timber steel or concrete at the same temperature levels as the internal temperature of the building.
From this same 2008 issue of chemistry world magazine we learned that over two billion tons of concrete are produced every year.
A warm flat roof or a built up roof bur is one where all the insulation is above the joists deck making them part of the warm fabric of the building.
Warm roof insulation ensures the entire roof structure is insulated meaning a warm deck roof is more energy efficient than a cold roof.
There are two ways to make a framework for a flat concrete roof.
The insulation can be adhered mechanically fixed or loose laid.
The breakdown warm roof vs cold roof.
A solid slab of concrete capping the top of your house.
A concrete roof is exactly what it sounds like.
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.
You can either use removable concrete forms or forms that are made of concrete and insulate the house.
