Elima-Draft Model# “ELMDFTRB3433”

Air Return/Large Vent Insulation Sheet 30” x 24”


Our insulative “bubble” sheets are the perfect solution for blocking cold drafts coming through air returns and vents which our solid covers cannot fit over (ie: large or odd sized vents). They can be cut to any size up to 30” x 24.” For return vents with hinged grates, simply cut the sheet to the size of your filter, place inside, and re-close the grate. That’s it!

If you have a vent that is a size/style that our solid covers do not fit, the sheet would attach to the outside of the vent, adhered by a fastener (we recommend using clear Velcro to blend in with the color of the vent).
