Inverted Flat Roof Construction

Rigid extruded polystyrene insulation has minimal water absorption due to its closed cell structure.

Inverted flat roof construction.

Then aquazone a high performance non woven polyethylene membrane is installed over the insulation to minimise the cooling effect associated with rainwater flowing down through the insulation and draining away. This module is sponsored by radmat. Inverted flat roof construction holds numerous advantages for flat roofing and provides the best solution because. This makes it the only material suitable and approved for inverted roof applications.

Protected waterproofing membrane the roofing membrane is installed on the roofdeck concrete deck. Benefits of inverted roofs. In an inverted roof construction the principal thermal insulation layer is located not only above the roof structure but also above the waterproofing resulting in the waterproofing structural deck and support structure being at a temperature close to that of the interior of the building. The roofing membrane is installed directly on top of the structural deck the water proofing membrane is protected by the insulation there is a simple build up of layers without an additional vapour barrier.

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. 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. In an inverted roof construction the sika trocal membrane is installed directly to the structural decking usually concrete and the innobond thermal insulation is installed on top of the membrane. An inverted or protected roof is a type of flat roof construction in which the waterproofing layer is placed below the insulation.

Suitable construction materials for inverted flat roof systems 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. A section of an inverted roof system using radmat s quantum vacuum insulated panel. Inverted roof designing buildings wiki share your construction industry knowledge. What is an inverted roof.

An inverted roof is quite simply where the waterproofing layer is installed over the structural deck rather than over the insulation. Due to its numerous advantages for flat roofing one of the best solution is the inverted roof construction. Insulation boards are loose laid on top of the membrane and then weighted down with paving slabs or gravel ballast.
