The semi-rigid batts are denser than traditional batts, making them easy to cut and install, with a secure cavity fit.


Measure & Cut: Fire & Sound Guard™ insulation is easy to cut with a serrated knife for custom fitting around electrical boxes, pipes, duct-work, wiring, or between non-standard studs and joist.

Squeeze & Insert: Fire & Sound Guard™ insulation is flexible and pliable; simply squeeze the sides to compress the insulation and insert into the desired wall.

Release & Expand: Once in place, Fire & Sound Guard™ insulation naturally expands to fill in the space, creating a snug, custom fit.
