The main differences between glass fiber roofing felt and glass fiber facing felt are analyzed
1、 Application scope:
1. Glass fiber roofing felt
It is mainly used as the base material of waterproof materials such as modified asphalt waterproof coiled material and color asphalt tile.
2. Glass fiber facing felt
It is mainly used for walls and ceilings to prevent paint cracking and orange peel. It is mostly used for decoration of large conference rooms and high-end hotels.
2、 Process characteristics:
1. Glass fiber roofing felt, as a kind of gel coat layer reinforced felt, is a kind of fiber distributed in all directions. Its softness makes it suitable for bodies with edges and corners, irregular shapes and complex curved surfaces. It is also suitable for a variety of composite materials. It can quickly dissolve with EP, VE, up and PU resins, forming a resin rich layer between fiber gaps, giving a smooth and flat surface, It can effectively avoid the hemp holes on the formed surface and the fiber lines hidden in the fibers. It also highlights the strengthening of interlaminar shear strength, surface toughness and excellent chemical and corrosion resistance.
2. Glass fiber facing felt has incomparable anti-seepage effect with ordinary waterproof materials. Its excellent elasticity and deformation capacity make it very suitable for expansion or contraction of base surface, and can effectively overcome the uneven settlement of base surface.
