Knauf Supafil® Cavity Wall – Glass Wool for Blown-In Cavity Wall Insulation 16.6 kg Bag

Knauf Supafil® Cavity Wall – Blown-in Glass Wool Cavity Insulation, 16.6 kg Bag

Knauf Insulation Supafil® Cavity Wall is a loose glass wool insulation without added binder, which is blown in using machine technology via hoses and nozzles as cavity insulation into the cavity of double-leaf masonry. The insulation is permanently water-repellent, resin-free and naturally non-combustible.

Properties & Benefits

• Specifically designed for blown-in insulation of double-leaf masonry (cavity insulation)

• WLS 035 at a bulk density of 30–40 kg/m³

• Hydrophobised throughout – permanently water-repellent (meets WS / WL(P))

• Non-combustible – building material class A1

• Settlement-proof: settlement class S1 (no measurable settlement < 1%)

• Solvent-free

Area of Application

For cavity insulation using machine technology into the cavity of double-leaf masonry.
