The semi-rigid batts are denser than traditional batts, making them easy to cut and install, with a secure cavity fit.
Measure & Cut: UltraBatt™ 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: UltraBatt™ insulation is flexible and pliable; simply squeeze the sides to compress the insulation and insert into the desired wall.
Release & Expand: Once in place, UltraBatt™ insulation naturally expands to fill in the space, creating a snug, custom fit.
UltraBatt™ insulation is available in a variety of sizes and R-values for your project.
