Fiberglass Tissue With Perforated Holes
Perforated fiberglass mat is a high-quality product that has been specifically designed for use as a base material for waterproofing base material. It is created by perforating a reinforced fiberglass mat with circular holes that are 4 cm in diameter.

PRODUCT DESCRIPTION
The perforated fiberglass mat is used as the base material of the vapor barrier membrane. After coating the bitumen on one side of the perforated fiberglass mat you get an ideal vapor barrier membrane. Lay the vapor barrier membrane on the roof with fiberglass side down and bitumen side up, then apply the bitumen membrane on it you get a perfect waterproof structure with a vapor barrier that can absorb the expanded air in high temperatures of summer, effectively avoiding the lump of bitumen membrane because of air expansion under it dramatically increased the lifetime of bitumen membrane.
Perforated fiberglass mat is produced from yarn-reinforced fiberglass mat with an even surface, excellent tensile strength, and ideal combined features of stiffness and softness. The perforation process is precise and creates a surface that is smooth and free of wrinkles, ensuring that the final product is of the highest quality. These features ensure the smooth and high-speed further producing process on the perforated glass mat and ensure the easy installation of the vapor barrier on the roof.
CHARACTERISTICS
Excellent tensile strength: Assured smooth and high-speed running of the vapor barrier membrane.
Smooth surface: Assured even coating of bitumen.
Combined features of stiffness and softness: Effectively avoided wrinkles during vapor barrier membrane production and installation.
