Multi-layer insulation material, especially for habitable loft rooms, has different layers to prevent transmission of heat, noise and damp

摘要

The insulation material consists of a series of juxtaposed and sealed layers, including black film (1), bubble film (2), solid aluminium film (3), soundproof layers (4), double-sided metallised reflective film (5), wadding (6), cellular separating layers (7), wool or other natural or synthetic fibre layers (8) and a protective and reinforcing mesh layer (9). The bubble film layers have bubbles measuring 0.8 - 4 mm in depth and 2 - 5 mm in diameter, spaced at least 8 mm apart to reduce contact points.
