Roofing Fiberglass Mesh
Roofing Fiberglass Mesh is a high-performance reinforcement fabric specifically engineered for roofing systems. It is embedded in waterproof coatings, bituminous membranes, acrylic coatings, and cementitious layers to prevent cracking, improve tensile strength, and extend the service life of roof waterproofing systems.
Product Information
GALAXYFIBER Roofing Fiberglass Mesh is manufactured from alkali-resistant glass fiber yarn with a specialized coating. It delivers excellent adhesion, flexibility, and weather resistance, making it ideal for flat roofs, pitched roofs, roof decks, terraces, and roof renovation projects.
Key Features
- Extreme Weather Endurance – Engineered to withstand prolonged UV exposure, heavy rain, snow, and freeze-thaw cycles on exposed roof surfaces.
- High-Temperature Stability – Maintains structural integrity under intense rooftop heat, where surface temperatures can exceed 70°C in summer.
- Thermal Stress Resistance – Absorbs the expansion and contraction caused by day-night temperature swings, preventing reflective cracking in roofing layers.
- Wind Uplift Reinforcement – Anchors roofing membranes and coatings against wind uplift forces on flat and low-slope roofs.
- Bitumen & Coating Compatibility – Bonds reliably with bituminous membranes, acrylic, polyurethane, and cementitious roof coatings.
- Ponding Water Resistance – Retains strength and adhesion in areas prone to standing water and prolonged moisture exposure.
- Dimensional Stability Under Thermal Cycling – Resists shrinkage and elongation over repeated heating and cooling cycles, keeping the roofing system dimensionally locked.
- Long Service Life – Extends the maintenance interval of roofing waterproofing systems, reducing re-roofing frequency and lifecycle cost.

Usage Precautions
- Storage: Store in a dry, ventilated area away from direct sunlight and moisture.
- Temperature: Install above 5°C for best results.
- Surface Prep: Ensure roof substrate is clean, dry, and free of dust, oil, or loose particles.
- Cutting: Use sharp scissors or a cutter; do not tear by hand.
- Embedding: Must be fully embedded in waterproof coating or membrane.
- Overlap: Maintain at least 10cm overlap between adjacent strips; 15–20cm at corners.
- Skin Contact: Wear gloves and long sleeves to prevent fiber irritation.
- Safety: Follow roof safety regulations and use proper fall protection.
