Why Use Fiberglass Base Felt for Roofing

By Guanlong Waterproof Materials Co., Ltd

If your waterproofing project calls for dimensional stability, fire resistance, and long-term reliability, then fiberglass base felt is the ideal solution. Widely used in flat roofing systems, it provides excellent reinforcement to bitumen membranes, especially where flexibility is less of a concern.

🔍 What is Fiberglass Base Felt?

Manufacturers bond glass fibers into a stable, mesh-like structure to create fiberglass base felt, a non-organic reinforcement mat. It’s commonly used in APP and SBS bituminous waterproofing membranes, especially in torch-on systems.

✅ Key Advantages

Exceptional Dimensional Stability
Keeps its shape even in extreme heat and cold—no curling or shrinkage.
High Fire Resistance
Naturally non-combustible, making it ideal for fire-rated roofing systems.
Cost-Effective
Provides great performance at a competitive price, ideal for large-scale construction projects.
Easy Installation
Its smooth, rigid surface is easy to apply and reduces labor time.

🏗️ Common Applications

Flat or low-slope commercial roofing
Warehouses, schools, government buildings
Residential terraces and patios
Fire-sensitive construction areas
