Single-ply membrane flat roofing applications

Use Celotex EL3000 high performance insulation in either mechanically fixed or fully adhered single-ply flat roofing applications. The unperforated facer is suitable for single-ply fully adhered roof systems, self adhesive membranes and liquid-applied membranes.

Alternatively, use Celotex TA3000 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.

When designing a flat roof using Celotex EL3000 or TA3000 boards, three basic principles apply:

1. Design to a fall of 1:80, 1:60 or 1:40 as appropriate to the weathering system, type of deck and construction tolerances.

2. Have due regard for the use and design of the building and the need to ensure that the design will not allow a build up of moisture below the waterproofing membrane.

3. Provide adequate protection for both insulation and waterproofing if significant foot traffic is expected either during or after the completion of the roof.
