Knauf Supafil® Loft Plus – Blown-in Glass Wool Insulation for Intermediate Floors 16.6 kg Bag

Knauf Supafil® Loft Plus – Blow-in Glass Wool Insulation, 16.6 kg Bag

Knauf Insulation Supafil® Loft Plus is a loose glass wool insulation without added binder, which is blown in using machine technology via hoses and nozzles onto intermediate floors as well as into open horizontal or moderately sloped frame structures. The insulation is permanently water-repellent, resin-free and naturally non-combustible.

Properties & Benefits

• Specifically designed for open blow-in insulation of intermediate floors

• WLS 038 even at low bulk density (20–23 kg/m³)

• Water-repellent throughout (meets WS / WL(P))

• Non-combustible – building material class A1

• Solvent-free, resin-free / without added binder

Areas of Application
