Insulation dowels for fixing calcium silicate boards to ceilings / sloping walls (sizes available for every board thickness)
The insulation dowel provides you with additional security when installing calcium silicate boards on ceilings, which we always recommend. The plugs are made of plastic, which prevents oxidation, corrosion and rusting. They are also completely halogen-free and prevent cold bridges.
In addition to professional full-surface bonding of the calcium silicate boards with special adhesive, we recommend additional fixing with dowels of at least 4 (from 80 mm thickness preferably 6) impact dowels per m² for room heights over 2.8 m and for ceiling installation and sloping walls.
Drill the plates without impact function!
