Would this be good to use on an attic floor?

Asked by: Dave
Hello Dave, Foamular may be used in this application, however, it would need to be installed over wood sheathing and covered with wood sheathing if you plan on using the attic for storage. Thank you for your inquiry!

I plan to use this in a project to create a insulation box for an attic whole house fan in the winter. Will this work?

I plan to use this to box in my whole house fan to prevent heat from going theough the fan louvers and into the attic. This is a big problem in cold northeast. I plan yo create a 36”x36l box with a cap and just glue it togther. Just taking the cap off in the warmer weather months. Will this work and any issues using in an attic space?
Asked by: VoidNY
I think it will. I'd use the adhesive made for foam board, and maybe add a few finishing nails, or something similar to hold it together, while the adhesive sets up.

FOAMULAR 250 2 in. x 2 ft. x 8 ft. R-10 Tongue and Groove Rigid Foam Board Insulation Sheathing is rated 4.6 out of 5 by 151.
Rated 5 out of 5 by from Great product I used it to make my own attic stair opening insulation. I am able to use a saw to cut pieces to my desire and glued it together. Once i put it on the attic opening, there is no more cold air draft and proved it using a infrared gun. This product works as expected.

Increments and can be cut with a razor knife - and the 250 product has a higher compressive strength than the formulae 150 for use under concrete slab. It functions as a vapor barrier (when properly sealed around edges).
