Roof Cassettes

The Streif Roof Cassette system

STREIF’s heavy duty roof cassette system is the ideal solution for mono pitched roofs, flat roofs and rooms in the roof, and especially where buildings need to be made watertight fast.

Streif Roof Cassettes

Manufacturing Process

Manufactured under controlled factory conditions our mono pitch roof cassettes come felted, battened and insulated if required. Our flat roof cassettes can be delivered with a factory fitted VCL to add an additional layer of protection during construction.

The solid timber rafters are strong – minimum 200mm x 60mm, C24 graded, Scots Pine, PEFC, 15% (±3%) moisture content, and fully treated to last.

About the System

Single cassettes are up to 13m long and 2.5m wide, and using STREIF’s special connection system almost limitless spans are now possible.

The system is very quick – with our highly trained crews up to 1,000m² of roof cassettes can be installed in a day, meeting the highest levels of quality and safety.

Streif roof cassettes which form part of our building system can be engineered to accept extensive green or blue roofs.
