Knauf ProtectFill – Blown-in Stone Wool Insulation for Fire Protection
Knauf ProtectFill is a blown-in insulation made of loose stone wool for fire protection upgrading in service/installation shafts. The material is blown directly into the shafts by specialised contractors via hoses and nozzles – fast, clean and reliable. In addition to fire protection, ProtectFill also provides thermal and acoustic insulation.
