Installing and Cutting STEICO Flex
STEICO Flex is slightly longer and wider than it needs to be to ensure that the STEICO Flex friction-fits in the cavity. STEICO Flex is easily with an insulation knife, a band saw, jigsaw or any power hand saw with two reciprocating serrated blades.

A handy tip is to cut while it is within the packaging. This ensures the batts are held tightly and compressed; making cutting easier.
