Processing/practical tips

Calcium silicate panels are processed like foamed mineral panels. They are easy to saw and drill.

The substrate must be clean and intact (cohesive). Non-cohesive plaster, dense paint and gypsum elements must be removed. For bonding the adhesive must be applied all over with a serrated trowel. The panels are aligned with offset butt joints.

Edges of differing height at the butt joints can be ground level after drying.

Especially for interior insulation, panels should fully adhere to the surface so as to avoid air circulation behind.

No vapour-proof layers, such as tiles or wallpaper with several layers of coating, may be applied to calcium silicate panels, because this decreases their vapour permeability.
