The Jablite Inverted Roof Insulation range of products is BBA-certified and approved to ETAG 031 (European Technical Approval Guidelines). It is currently supplied in two grades to meet the compression performance specified.
The insulation boards are designed with an overlap to prevent uplift during installation and can be specified in 1mm increments to meet the required U-values. The specified thermal performance of the inverted roof is achieved through the roof design and the thickness of the insulation used.
An inverted roof construction places thermal insulation above the waterproof layer. This maintains the waterproof membrane at an even temperature and protects it from the damaging effects of UV radiation or the effects of the weather.
