Rainspan is a fully tested, robust, interlocking, stone wool core insulated panel, with two hour fire resistance even in long span conditions of up to 7.5 metres (LPS 1208).

Rainspan uniquely blends together the benefits of a composite panel and the flexibility of varying aesthetic rainscreens to provide greater freedom for architectural expression. It is fully tested with comprehensive details to ensure top performance for the life of the building. Rainspan provides the perfect structural support for rainscreen systems, and combines ease and speed of installation to create a weather tight building envelope early on in the build programme.

It can remove the façade installation from the critical path and simplify the construction process and helps to reduce the cost and complexity of the façade support structure.

Tested Performance

Rainspan finished wall construction has been tested for structural and weather integrity performance to CWCT standards and fire resistance tests conducted in accordance with BS EN 1364 Part 1 to ensure 'built in passive fire protection
