Delta Duct Reinforced Alu Foil Tape (FR Grade)

Flame-Retardant • Foil-Scrim Reinforced • HVAC Sealing Tape

Delta Duct Reinforced Alu Foil Tape (FR Grade) is a high-performance foil–scrim laminate tape specifically engineered for HVAC duct sealing and insulation applications. It features a 25-micron aluminum foil reinforced with a 2-way scrim (5 × 5 mm), coated with a transparent solvent-based acrylic adhesive, and protected by an easy-release silicone liner. This advanced construction ensures superior adhesion, reflection, and vapor barrier performance under demanding indoor and outdoor conditions.

With excellent flame-retardant properties and long-term durability, Delta Duct Reinforced Alu Foil Tape (FR Grade) delivers reliable performance for duct joints, seams, and insulation systems where safety, strength, and thermal efficiency are essential.

Key Features

• Foil-scrim backing reflects heat and light effectively, improving insulation performance
• High-quality acrylic adhesive provides superior adhesion and holding power
• Long-lasting sealing for HVAC foil-scrim facing joints and seams
• Low moisture vapor transmission ensures excellent vapor barrier integrity
• Wide service temperature range: -30°C to +120°C for reliable indoor and outdoor use

Applications

Delta Duct Reinforced Alu Foil Tape (FR Grade) is widely used across HVAC and industrial insulation systems, including:

• Sealing foil-scrim facing laminated fiberglass blankets, duct boards, and pipe sections
• Joining and connecting flexible air duct seams
• Thermal insulation sealing in HVAC and industrial systems
• Reflective and flame-retardant applications requiring durable bonding

Note: Ensure surfaces are clean, dry, and free of grease or oil before application for optimal adhesion.
