| 摘要 |
The present invention relates to a flat roof composite comprising a resin-impregnated mineral fibre layer (1), a fabric layer (2) with impregnated adhesive throughout the layer, the adhesive penetrating also into the surface of the mineral fibre layer, and a moisture impermeable sheet (4) adhered to the fabric layer by the adhesive (5). The fabric is preferably formed of woven strands (3) of glass fibre filaments. The fabric is united with the mineral wool insulating core prior to passage through the curing oven which cures the resin applied to the mineral wool in the spinning chamber. The size of the apertures between strands of glass fibre filaments is selected so as to allow penetration of liquid adhesive into the wool and reduces delamination of the water impermeable sheet. |
