Warm Deck Roof Detail

Warm cold and inverted.

Warm deck roof detail.

There are three recognised designs of flat roof construction. Inverted warm deck roof. The insulation is immediately below the waterproofing layer. There is a likelihood that this practice could contribute to a condensation risk and therefore it would be strongly recommended to have a condensation risk.

The insulation is placed below the waterproof covering and is either mechanically fixed or bitumen bonded on to the top of the deck. The vapour control layer is above the decking but below the insulation. A warm deck roof is where the insulation is placed on top of the rafters joists and the roof covering is then placed over the insulation. Cold deck roof a cold deck roof is where the insulation is placed between the joists rafters or in.

Therefore water vapour which enters the roof structure from the room below will not have a cold surface on which to condense. The warm deck roof design is the modern method for flat roof construction and is preferred wherever this option is possible. In a warm roof construction the principal thermal insulation layer is located above the structural decking resulting in the structural deck and support structure being at a temperature close to that of the interior of the building. So called because the insulating layer is located above the roof rafters and between the structural supports a warm deck roof results in a temperature for the roof and loft area that is consistent with the rest of the.

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. No ventilation is required for these types of roofs. The insulation can be adhered mechanically fixed or loose laid. It is the most acceptable type of construction for domestic possessions and belongings as it avoids the need for aeration of the roof construction.

There are two forms of warm deck roof. It is not unusual for designs to keep roof levels to a minimum and there is a trend when designing a warm roof to include some of the insulation below the structural deck as well as above. This usually keeps the deck warm. A warm deck also provides added protection from the dangers of condensation as the structure is kept warm at a temperature above dewpoint by the insulation above it.

This video will demonstrate how to install a cure it grp waterproofing system in a warm roof build up. In case of warm roofs they have an insulation above the roof deck in this way it keeps. 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.
