Inverted Warm Deck Roof

The structural roof deck should be fully waterproofed in accordance with the manufacturer s design guidance and details.

Inverted warm deck roof. Warm cold and inverted. Inverted roof designing buildings wiki share your construction industry knowledge. Inverted roofs are a type of warm flat roof where the insulation is above the waterproofing layer. Two layer inverted warm deck roofing system incorporating a range of styrene butadiene styrene sbs modified elastomeric bitumen membranes and accessories total torch membranes incorporate a striped pattern.

Water control layer installation is as follows. 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. 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. 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.

Insulation for walls including cavity walls solid walls and timber or steel framed walls. Benefits of inverted roofs. High performance roof insulation suitable for use in a range of inverted roofs including green roofs and protected membrane flat roofs. 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.

The system is also referred to as. This advanced vapour release technology has been designed to dissipate any moisture vapour that may be trapped in the roofing system. There are three recognised designs of flat roof construction. An inverted roof also referred to as a protected membrane or upside down roof is form of flat roof in which the waterproofing layer is beneath the thermal insulation rather than above it.

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.
