Gray Caulk Cord Rubber Window Weatherstrip, M-D 90-ft x 1/8-in
In addition to creating insulating airspaces with our clear acrylic, WonderWindow tape & Spacer Stix, as needed, sealing the seams where sash rails come together or where sash meets frame prevents air infiltration at these locations. The flexible rope caulk is put in place a string at a time just to adhere over the crack: no need to mush it in place. With care, it can be removed and reused for several years.
Can be picked up at the Lowe’s of your choice, or delivered within their delivery area for an added $28 per delivery.
