Rainscreen façade systems are lightweight when compared to brick and masonry solutions and can provide the designer with a wide range of aesthetic options.
In addition to thermal performance, fire performance of insulation materials is a crucial consideration, particularly when designing buildings over 18m in height or when the building is to have high occupancy levels or be used by vulnerable occupants.

Why Mineral Wool?
Non-combustible, being suitable for use on all buildings including those above 18m in height providing compliance with fire related building regulations.
Contributes to building regulation compliance without reliance on separate testing or desktop studies.

|SFS inner leaf with OmniFit Slab between studwork||Dense block inner leaf|
|Rainscreen Slab (mm)||100mm SFS||150mm SFS||100mm Block|
NOTE: The above are based on aluminium helping hand brackets with base dimensions 75 x 62mm sat on a 5mm PVC thermal break pad, bracket is 4mm thick, aluminium bracket length to give 50mm residual cavity. Dense block as λ=1.13, steelwork as 2mm with 50mm flange at 600mm centres infilled with OmniFit Slab. Internal lining is standard 2 x 12.5mm wall board, cement particle sheathing board. Cavity is fully ventilated.
