Flat Warm Roof Build Up

The definition of a flat roof according to bs 6229 is having a pitch less than 10 o to the horizontal however some in the industry would consider up to 15 o as their definition of a flat roof.

Flat warm roof build up.

Warm flat roof fully packed with insulation to prevent any condensation build up. A good roof requires maintenance like any. In the warm flat roof construction there is insulation packed into every possible space where air can flow. It can also prevent pest from entering.

A great home requires a great roof. The major difference between the warm flat roof and the cold flat roof has to do with the air flow between the roofing timbers known as joists that help to hold up the roof. Flat roof constructions are generally classed as either cold or warm. 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.

Warm cold and inverted. There are three recognised designs of flat roof construction. 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. Thermoplastic or elastomeric are the most effective and should extend up adjacent walls at least 150mm from the roof surface.

A roof is mainly considered to keep out rain and snow from a building. A great and strong roof ensures no trouble during rain and strong winds for the residents. When building a flat roof it is vital that a degree of falls is built into the construction to ensure rainwater run off. In these days of energy preservation a roof can also contribute to preventing warmth being lost from a building.

Or else on the interior of the building just. Warm roof build ups can be installed on most modern construction material types such as concrete timber and timber based sheets. Others would treat even steeper pitches as flat roofs. 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.
