3M Fire Protection

The only fire rated duct wrap product you’ll need to protect grease and air ducts in an easy to install format. Certified shaft alternative 1 and 2 hour fire rated duct wrap. Certified to ASTM E2336 (including ASTM E119 engulfment) and ISO 6944 test standards among others.

2 hour fire protection.

Lightweight (6lbs per cu ft) and thin (1.5” *) for easier application

Ideal for sealing building joints, penetration seals and perimeter joints between fire-rated floors (concrete, fireproofed fluted steel decks) and fire-rated walls (gypsum, concrete). Applied as 1/8 inch (3mm) thick coating with an airless sprayer, this water-based coating dries in ambient conditions to form a flexible seal with compression/extension of up to +/- 50% of nominal joint width.

• Dries quickly to dark gray or red with consistent spray patterns
• Less waste — color makes coverage easy to see which helps prevent re-spraying or over-spraying
• STC rating 56 when installed in a 56 STC rated wall assembly
