Inverted Roof Insulation System

Quantum is an innovative insulation system that can revolutionise a construction build.

Inverted roof insulation system. Also known as a protected membrane or upside down roof inverted roofs employ insulation which can resist water absorption provide excellent thermal performance be unaffected by freeze and thaw cycles withstand surface traffic and be protected from uv and mechanical damage among others. The world s thinnest inverted roof insulation once in a while a british product is developed which is an industry game changer. In an irma the system s insulation is installed above the waterproofing membrane instead of below as in a conventional roof assembly. Inverted flat roof waterproofing combined with a thermal insulation is essential for a buildings waterproofing and energy saving thermal insulation.

An inverted roof is quite simply where the waterproofing layer is installed over the structural deck rather than over the insulation. Insulation boards are loose laid on top of the membrane and then weighted down with paving slabs or gravel ballast. One of the main benefits of the inverted roof method is that the membrane is protected by the insulation from the expansion and contraction caused by weather fluctuations such as frost and solar radiation. It is also protected from damage by traffic on the roof such as people walking the movement of equipment and so on.

Used as part of established inverted roof systems it offers a euroclass a1 rating and a high compressive strength. Inverted roofs are designed with the waterproofing layer usually a liquid applied membrane beneath the insulation. Invented by dow in the late 1960 s an inverted roof system uses dupont styrofoam brand xps insulation to protect the membrane helping improve the performance and longevity of the entire roof system. Whilst the inverted roof is a robust system the insulation layer does not benefit from the protection of the waterproofing membrane.

The mariseal system inverted flat roof waterproofing method offers a simple build up waterproofing that features a protected waterproofing membrane and loose laying insulation boards. Inverted roof membrane assembly irma can be constructed. This makes it the only material suitable and approved for inverted roof applications. It is therefore essential the insulation layer is rot proof and durable.

The membrane is further protected by ballast overtop the insulation. Inverted roof systems are also referred to as upside down roof assembly. Rigid extruded polystyrene insulation has minimal water absorption due to its closed cell structure.
