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 to provide a robust and completely level platform, they’re ready to receive floor coverings or secondary systems.

The solid timber joists are strong – minimum 240mm 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 floor cassettes can be installed in a day, meeting the highest levels of quality and safety.

Suitable for timber frame, masonry or steel frame construction, and routinely strong enough and stable enough to receive full sand and cement screeds.
