Celotex TA4000 Flat Roof Boards - Heavy Traffic

Presently, these boards are only available from Celotex when manufactured to order

Product Functions Celotex TA4000 Flat Roof Boards for Heavy Traffic

Celotex TA4000 Flat Roof PIR Boards are purpose designed for single-ply flat roofing applications.

Use Celotex TA4000 high performance insulation in mechanically fixed, single-ply flat roofing systems where the higher compressive strength of the board gives improved resistance to site traffic during installation. Fitted under mechanically fixed single-ply PVC membranes and EPDM membranes

Product Description

TA4000 is a fire rated board, purpose designed for single-ply flat roofing applications that have a higher compressive strength which gives improved resistance to site traffic during installation. Now with their higher compressive strength, mechanically fixed, single-ply roofing system, TA4000 boards provide a quick and easy method of achieving effective thermal insulation in a single-ply flat roofing application.

With low emissivity foil facings and specifically for use in mechanically fixed and ballasted single-ply systems, TA4000 boards have a higher compressive strength which gives improved resistance to site traffic during installation.
