On flat roofs a warm roof is one in which the insulation layer is laid on top of roof structure.
Warm deck flat roof definition.

In a warm flat roof construction the insulation is positioned above the structural deck and no ventilation is required.
Construction studies drawing detail showing how to draw a flat roof warm deck construction detail to a scale of 1 10 with a short introduction highlighting t.
In terms of the thermal design of a flat roof what are the options and the best practices of flat roof build ups.
When we talk about a warm roof vs a cold roof what we re really talking about is the insulation of the flat roof.
The thermal efficiency isn t as good as with warm roof.
Flat roofs are an ancient form mostly used in arid climates and allow the roof space to be used as a living space or a living roof flat roofs or low slope roofs are also commonly found on commercial.
The insulation is immediately below the waterproofing layer.
A flat roof is a roof which is almost level in contrast to the many types of sloped roofs the slope of a roof is properly known as its pitch and flat roofs have up to approximately 10.
This is as opposed to a cold roof in which the insulation is below or within the roof.

Installing a warm roof can be extremely straight forward and simple to do.
Basically there are two options to choose from when insulating a flat roof.
The sandwich warm deck roof is the most common type of flat roof.
A cold flat roof insulation requires more work taking off old boards and replacing them and the roof surface.
The insulation can be adhered mechanically fixed or loose laid.
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 placed below the waterproof covering and is either mechanically fixed or bitumen bonded on to the top of the deck.
There are two forms of warm deck roof.
The breakdown warm roof vs cold roof.
In the case of a flat roof insulation is usually either a rigid board above the deck or a mineral glass wool quilt immediately.
The vapour control layer is above the decking but below the insulation.
Throughout the course of the year the roof deck and all below it is kept at a temperature close to that of the inside of the building therefore the roof structure is protected from extremes of hot and cold lessening the.
This results in the structural deck and its supports being at a temperature closer to that of the building s interior.
