Inverted warm deck 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 above the underdrawn ceiling depending on the type of roof design and construction. Inverted roof designing buildings wiki share your construction industry knowledge. Warm cold and inverted. The structural roof deck should be fully waterproofed in accordance with the manufacturer s design guidance and details.

High performance roof insulation suitable for use in a range of inverted roofs including green roofs and protected membrane flat roofs. Water control layer installation is as follows. The great benefit of inverted roofs is that the insulation protects the membrane from extremes of weather such as frost uv exposure and the expansion and contraction that comes about from summer winter temperature cycles which can be as much as 80 c on some roofs. Insulation for walls including cavity walls solid walls and timber or steel framed walls.

Inverted roof systems in this type of construction the principal thermal insulation material is applied on top of the weatherproof covering so that the complete roof construction including roof covering is kept at warm temperatures during the winter months and at moderate temperatures during the summer months. This means that the insulation should be highly resistant to water absorption for example an extruded polystyrene based product which will not be affected by water or repeated freeze thaw cycles. This advanced vapour release technology has been designed to dissipate any moisture vapour that may be trapped in the roofing system. 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.

The system is also referred to as. Simply defined as a type of roof construction where the waterproofing layer lies beneath the insulation instead of above it as in other forms of roofing inverted roofs ensure that the complete roof construction including roof covering is kept at warm temperatures during winter months and at moderate temperates during the summer months. Insulation suitable for inverted roof applications such as the polyfoam xps roofboard range should then be loose laid in a brick bond pattern again in accordance with instructions and details provided. There are three recognised designs of flat roof construction.

Inverted roofs are a type of warm flat roof where the insulation is above the waterproofing layer.
