Blowing wool ROCKWOOL Granrock Super

Blowing wool Rockwool GRANROCK is non-combustible stone wool insulation for existing and new attics. With in-situ formed insulation you can easily insulate the cavities between piping and roof constructions, creating a seamless insulation layer.

Technical information

• Product fire protection class - A1
• Declared thermal conductivity
•         λD = 0.042 W/m∙K (at a dry density of 25-35 kg/m3)
•         λD = 0.040 W/m∙K (dry density 40-50 kg/m3)
•         λD = 0.037 W/m∙K (with a dry density of 55–65 kg/m3)
• Short-term water absorption ≤ 1.0 kg/m2
• Vapor permeability - μ = 1

The most important features:

• Ideally fills hard-to-reach horizontal spaces in unusable attics or pitched roofs;
• Loose wool can be used for ceiling or even exterior wall insulation;
• Blowing stone wool can be blown in three different densities, so not only horizontal but also vertical structures can be insulated. The required density of wool for the insulation of unusable attic spaces is 30 and 45 kg/m3, but in pitched roofs, operable attics, three-layer masonry and frame walls, the density is 60 kg/m3;
• Blowing stone wool GRANROCK SUPER is non-combustible.
