Description

Intumescent fire seal strips expand rapidly when exposed to heat or high temperatures to prevent heat and fire transfer through the gaps around the door. Mortised into wood doors and frames, or into edge strips of wood or composite door leaf, these strips are unobtrusive and permit the door to maintain a clean, neat appearance. PSA Tape lining the back of the strips make for a no-hassle placement on desired surface.

Available in many thicknesses and widths, these strips provide a range of 30-60 minutes of fire resistance, depending on strip size and type of door and frame construction. Please see Product Specs Tab for specific size options. For sizes not available through our site, contact us or call at 845-388-1300 for a quote.

The thicker strips are suitable for softwood constructions or where the gap between the door and the frame is greater than usual. Larger seals also help to control door distortion. Intumescent strips may also be used between the door frame and masonry.

The wide range of strip sizes were all tested to positive pressure standards, including UBC 7-2 1997 and BS 476-Part 22 1987.

Available in black and supplied in strips up to 8 FT length. Other colors and sizes available upon request. To order without pressure-sensitive adhesive (PSA) tape, contact us or call at 845-388-1300.
