Warm Deck Roof Built Up

In a warm roof the thermal insulation is immediately below the membrane finish the structural deck any voids and the ceiling are at a temperature close to that of the building s interior condensation control is achieved by using a vapour control layer vcl on the warm side of the insulation.

Warm deck roof built up.

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. In the case of a flat roof insulation is usually either a rigid board above the deck or a mineral glass wool quilt immediately. 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. Types of warm deck roof.

In principle this keeps the structural deck usually trapezoidal steel or timber at more or less the same temperature as the inside of the building. Inverted warm deck roof. In a warm roof construction the sarnafil membrane and sarnatherm thermal insulation is installed above the structural decking. The insulation can be adhered mechanically fixed or loose laid.

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. The recognised flat roof build ups for best design practices are. In terms of the thermal design of a flat roof what are the options and the best practices of flat roof build ups.

There are two forms of warm deck roof. Cold flat roofs are typically avoided as you d need to install ventilation which can prove problematic for many reasons relating to. The insulation is immediately below the waterproofing layer. A flat roof where the insulation sits below the waterproof membrane and above the structural deck is a warm roof deck.

Warm cold and inverted.
