Therma TT46

Therma TT46 is a rigid tapered PIR roof insulation board faced on both sides with a composite aluminium foil facing. It provides insulation and drainage in one, designed to enhance water drainage from flat roofs, which are waterproofed with mechanically fixed single-ply waterproofing. We provide a supporting design service to identify the most cost-effective tapered system design solution for flat roofs to meet rainwater run-off and insulation requirements.

Product Highlights

Suitable for use with mechanically-fixed single-ply waterproofing systems
Insulation and drainage in one - a practical alternative to screeding, structural falls or furrings
Supported by a bespoke design service
Load bearing implications for an existing structure can be minimal
Compatible with most green roof systems
