Easy To Install

Step 1

Using a serrated knife, cut the batt to ﬁt into the height

of the joist, which is typically 8 inches. If the joists are

16 inches apart, you can use one of ROXUL

’s 16-inch

wide batts. Also available in 24” on centre.

Step 2

Insert, compress and release the batt to ﬁt snugly inside

the header cavity, against the exterior wall and between

the joists. Ensure no gaps or voids for the heat to escape.

Two Easy Steps Insulate

a Basement Header

Insulating the basement header is an often forgotten part of a home renovation project. The header

refers to the typical 8-inch gap between the top of the basement's concrete wall and the ﬂoor above.

When left exposed, the header space can cause drafts and make your furnace work harder. That's why

it pays to insulate the area with thermal insulation like ROXUL COMFORTBATT

to reduce the heat loss

and make your basement more comfortable.

Working with ROXUL

insulation is a

breeze. It cuts quickly and accurately

with a serrated knife, such as a bread

knife, so you can easily achieve optimal

ﬁt around pipes, electrical boxes, wiring,

ductwork, and between studs and joists

that are less than a standard width.
