ABSTRACT:
Improved roof insulation for vehicles is provided. The insulation includes a layer of glass fibers held by a binder, which layer is flexible and compressible. A non-woven sheet is adhered to the lower surface of the fibrous layer and thereby improves the handleability of the layer and retains particulate material and especially fibers in the layer when being installed in a vehicle. The non-woven sheet also adds a degree of stiffness to the fibrous layer to prevent excessive drape thereof when being installed overhead, and yet the flexibility of the layer is retained. The non-woven sheet also protects the fibrous layer from tearing during installation and preferably can be dyed, which is particularly important when perforate headliners are employed therebelow. A non-woven porous sheet also can be employed on the upper surface of the fibrous layer which further improves the handleability and dimensional stability thereof, and protects the fibrous layer from damage. The upper porous sheet enables adhesive used to affix the layer to the lower or inner surface of the vehicle roof to penetrate the sheet and extend into the fibers. The upper sheet also serves as a net-like reinforcement for the adhesive.
