Inverted Flat Roof Design

Inverted roofs are designed with the waterproofing layer usually a liquid applied membrane beneath the insulation.

Inverted flat roof design.

In terms of the thermal design of a flat roof what are the options and the best practices of flat roof build ups. Also different architectural styles will use the same type of roof. Both scenarios would require safe general access and may lend themselves to a ballasted inverted or green roof design. There are three recognised designs of flat roof construction.

The iko armourplan pvc membrane offers a robust solution for inverted roofs and the next generation iko spectraplan membranes in addition offer non capillary construction to prevent moisture absorption. In the case of a flat roof insulation is usually in the form of either a rigid board above the deck or a fibrous quilt immediately above the ceiling depending on the type of roof construction.

Flat roof design guide. Intricate roofs have many parts that incorporate several of the basic roof designs such as a gable roof sitting atop a gambrel or variations of the gable valley roof design using one or a variety of different types of roof trusses also see our very detailed diagrams showing the different parts of a roof truss. The recognised flat roof build ups for best design practices are. Your roofing design can be completed with a range iko polymeric ancillaries such as primers and adhesives detailing and outlets mechanical fixing and clamping bars and many others to.

High performance roof insulation suitable for use in a range of inverted roofs including green roofs and protected membrane flat roofs. In the case of a flat roof insulation is usually either a rigid board above the deck or a mineral glass wool quilt immediately. As the waterproofing is protected from mechanical damage uv degradation. Benefits of inverted roofs.

Insulation boards are loose laid on top of the membrane and then weighted down with paving slabs or gravel ballast. Because of the danger of condensation the complex structural design and the problematic breathability the double shell cold roof as a possible structural design solution for flat roofs is not commonly used. The advantages of the inverted roof reveal themselves when compared to any other flat roof solution.
