Inverted roof insulation boards. 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. An inverted roof is a form of flat roof where the waterproof layer is beneath the insulation rather than above it. Inverted roofs have their waterproofing layer beneath the insulation instead of above it as in other forms of roofing. This will result in less than 2 compression in the insulation boards over 50 years.

Therefore jablite inverted roof 200 would be specified having a design load of 90kn m at 1 nominal compression. Benefits of inverted roofs. An inverted roof is quite simply where the waterproofing layer is installed over the structural deck rather than over the insulation. For use with inverted roofing waterproofing such as permaquik pq6100 eshaflex eshauniversal and paraflex.
