Delta Duct Alu Glass Tape (FR Grade)

Flame-Retardant • Reinforced Strength • HVAC & Industrial Grade

Delta Duct Alu Glass Tape (FR Grade) is a premium foil-glass cloth laminate tape composed of a 7-micron aluminum foil combined with a 10×10 mesh 85 gsm glass cloth. The layers are bonded with a flame-retardant acrylic adhesive and protected by an easy-release liner. This high-strength composite tape provides superior mechanical durability, temperature resistance, and long-lasting adhesion for professional HVAC and industrial applications.

Engineered to deliver maximum tensile strength and tear resistance, the FR-grade construction ensures enhanced fire safety and performance reliability under demanding conditions. Ideal for both insulation sealing and surface protection, Delta Duct Alu Glass Tape is a trusted choice in thermal and acoustic insulation systems.

Key Features

Reinforced foil–glass cloth laminate for exceptional strength
Flame-retardant (FR) grade adhesive formulation for safety and compliance
High tensile and tear strength for long-term durability
Excellent temperature resistance from -20°C to +120°C
Aging-resistant design ensures reliable performance over time

Applications

This flame-retardant aluminum glass tape is designed for sealing insulation joints and seams on foil–glass cloth surfaces. It provides a strong, permanent barrier against moisture, vapor, and air leakage in:

HVAC duct insulation and jacketing systems
Thermal and acoustic insulation wrapping
Industrial sealing and reinforcement applications
Fire-rated insulation systems and energy-efficient enclosures

Note: Ensure all surfaces are clean, dry, and free from grease or oil before applying the tape for optimal adhesion.
