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.
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
