Easy to cut to size and install, and it creates a solid seal that noticeably reduces drafts and outside noise. The foam material is dense and holds its shape well over time. Great for doors or windows that have gaps. Simple home improvement that makes a real difference - especially worth it in winter. ### ⭐⭐⭐⭐⭐ Works fine *by on Reviewed in the United States August 3, 2026* It fills gap between glasses. The gap made with an AC installation to the window. ### ⭐⭐⭐⭐⭐ Easy to work with, squeezes and stuffs into tight spaces. *by on Reviewed in the United States January 21, 2026* This was exactly what I needed.Was installing a diesel heater and needed to exhaust through a double hung window. Needed something to block air around the board I used. This worked great!Easy to press into the sides of the window jamb to block air from getting any further. Easy to manipulate/squeeze to get into tight spaces.Definatly blocks the cold air. The thickness was perfect, the quality of the material is great.I have some left over that I'll use with my air conditioner when summer comes. ## Frequently Bought Together - M-D Building Products 02006 1-1/4 in.
