Jablite has developed the first BBA-certified tapered Insulation for inverted or protected membrane roofs. This unique tapered insulation for inverted roofs provides a bespoke-designed drainage fall - removing the need for a screed layer.
An inverted roof construction places thermal insulation above the waterproof layer. This maintains the insulation at an even temperature and protects the waterproof membrane from the damaging effects of UV radiation and the effects of the weather.
The specified thermal performance of the inverted roof is achieved through the roof design and the thickness of the insulation used. U-values as low as 0.10W/2mK can be achieved.

Jablite Tapered insulation for inverted roofs is produced to the requirements of BS EN 13163 ‘Thermal insulation products for buildings – Factory made products of expanded polystyrene (EPS) – specification’.
Tapered Insulation for Inverted Roofs is a great choice because:
|+||Does Jablite’s manufacturing process use a lot of energy?|
|No. Compared with other insulation materials, the manufacturing process uses only small amounts of energy as the Jablite EPS bead is expanded by steam.|
|+||Does Jablite manufacture to ISO 14001?|
|Yes, Jablite is certified to the BS EN ISO 14001 Environmental Management System standard.|
|+||Is Jablite accredited to ISO 9001?|
|Yes, all Jablite sites are accredited to BS EN ISO 9001 Quality Management System.|
