Inverted Roof Insulation Boards

Benefits of inverted roofs.

Inverted roof insulation boards.

Inverted roofs have their waterproofing layer beneath the insulation instead of above it as in other forms of roofing. Not only do we withstand hail damage but our roof boards maintain their bond to the roof membrane lowering the likelihood of a catastrophic roof failure. An inverted roof is a form of flat roof where the waterproof layer is beneath the insulation rather than above it. For use with inverted roofing waterproofing such as permaquik pq6100 eshaflex eshauniversal and paraflex.

Protherm sd upstand insulation board has a zero ozone depletion potential odp a global warming potential gwp of less than 5 and an a rating in accordance with the green guide to specification. Styrozone inverted roof insulation boards properties everything you need to know about styrozone h 350 r board since roofs are generally very vulnerable when it comes to effects of external factors such as extreme temperatures rainfall air filtration they need special attention and protection. We also have insulation boards suitable for more specialist roof applications for example inverted roof insulation and balcony insulation.

This will result in less than 2 compression in the insulation boards over 50 years. The design load to use for jablite inverted roof insulation for this application is 30 of the 10 compressive strength figure. Therefore jablite inverted roof 200 would be specified having a design load of 90kn m at 1 nominal compression. This makes it the only material suitable and approved for inverted roof applications.

It is the insulation for protected membrane flat and green roofs. Insulation boards are loose laid on top of the waterproof usually a liquid applied membrane and then weighted down with paving slabs or gravel ballast. Jablite premium inverted roof insulation boards in 200 300 and 200 grades have adequate resistance to the loads associated with light maintenance traffic on roofs and to pedestrian foot traffic on balconies and roof terraces. Our range of inverted roof insulation has high compressive strength and increased resistance to water absorption.

Rigid extruded polystyrene insulation has minimal water absorption due to its closed cell structure. Jablite supplies insulation boards in a range of grades suitable for all flat roof applications. An inverted roof is quite simply where the waterproofing layer is installed over the structural deck rather than over the insulation.
