Knauf Supafil® Timber Frame – Loose Glass Wool, 16.6 kg Bag

Knauf Supafil® Timber Frame – Blown-in Glass Wool Insulation Bag 16.6 kg

Knauf Insulation Supafil® Timber Frame is a loose, water-repellent mineral wool / glass wool insulation for timber construction structures. It is blown into cavities using machine technology via hoses and nozzles and is suitable for insulating cavities in walls, ceilings and roofs – economical for new-build projects (prefabrication or on-site) and also ideal for refurbishment, adding storeys and multi-storey timber construction.

Properties & Benefits

• Blown-in insulation for timber frame construction: walls, ceilings, roofs
• Water-repellent, resin-free / binder-free
• Very good thermal performance: design thermal conductivity λ = 0.035 W/(m·K)
• Building material class A1 (non-combustible)
• Settlement-proof: settlement class S1 (no measurable settlement ≤ 1%)
• Sound insulation is significantly improved
• High throughput during installation, no offcuts, highly compressed (transport/storage)

Areas of Application

For insulating cavities in walls, ceilings and roofs in timber construction (e.g. timber frame / timber frame structures). Suitable for new-build (prefabrication or on-site) as well as roof refurbishment, adding storeys and external walls in multi-storey timber construction.

Installation

• Installed as blown-in insulation using suitable machine technology (blowing machine) into closed cavities.
• Thanks to the high compaction, the insulation layer remains stable if building components are opened later (settlement-proof).

Technical Data

• Standard: Mineral wool loose-fill insulation according to DIN EN 14064-1
• Designation key: MW EN 14064-1-S1-WS-MU1
• General building authority approval: Z-23.11-1902
• Reaction to fire: A1
• Declared thermal conductivity: λD = 0.034 W/(m·K)
• Design thermal conductivity: λ = 0.035 W/(m·K)
• Bulk density: 30 – 40 kg/m³
• Nominal mass per bag: 16.6 kg

Material Requirement (Guide Values)

Material requirement depends on the frame width and the desired thermal insulation performance. As a guide (at 30 kg/m³), the minimum consumption per 100 m² is, for example:

• 100 mm (R-value approx. 2.9): approx. 18.1 bags / 100 m²
• 140 mm (R-value approx. 4.1): approx. 25.3 bags / 100 m²
• 200 mm (R-value approx. 5.9): approx. 36.1 bags / 100 m²

Supply form: Bag 16.6 kg
