“Insu-Rope rock wool insulation ropes with different diameters and for different purposes. Insulation ropes are flexible enough to enable easy installation in less accessible parts of constructions.” For fire and thermal protection of construction expansion joints we use Insu-Ropes of different diameters. In case of fire this insulation solution slows down the spread of fire, fume and toxic gases, and consequentially provides more time to evacuate people. Rock wool insulation ropes also contribute to maintain appropriate microclimate in buildings; “its vapor permeability protects buildings from humidity.”
