Window Inserts LLC

"The kitchen in my home has single pane casement windows; both which, in the winter, are extremely cold to the touch. That essentially translates into heat loss aka money loss. I ordered two of these inserts and wow am I impressed with the immediate difference they made. They keep the cold air out and the hot air in. They aren't even cold to the touch as the glass is. Shipping was fast, they were nicely packaged, and installation took all but a minute. Will definitely order more if needed."

"We ordered inserts for our screened in porch and door. The panels fit perfectly. We received them in a very timely manner. We couldn't have asked for a better product. Thank you Window Inserts for doing such an outstanding job. Not only will these inserts keep our porch warmer in the winter, but keep the pollen out in the springtime. We absolutely LOVE them! Highly recommend this company to anyone looking to insulate their windows. Easy to install and will be easy to remove."

"Filled order fast"

"We use these for all of our skylights year round. Major improvement in the cost to heat and cool. Very easy to install. Our oldest ones are 7 years old and just like new."

"Ordered them from southern Ontario for a patio door and main bedroom. Followed the instructions at the web site which are very well written and easy to follow. I used a laser measure for a accurate measuring. They arrived very well packed and had no issues with that at all. Installed the ones for the patio door today and they went in very easy and fit great. The patio door is a single door that opens out and has one fixed window next to it. Use to install a window kit but that was tricky on the patio door as the frame was uneven and not square all around. These look good and are extremely easy to remove as well. Highly recommend this interior storm window for you home. Update: Inserts have been installed for about a month. Patio door and bedroom. Patio door still has some condensation and icing on the bottom of glass but a little less than without. Also noticed some fogging in a couple of spots on the inside but they could be just humidity which is up to me to control. Having used window kits they you buy in local stores their would be not condensation or icing at all as they are air tight. The inserts are not air tight and I would not expect them to be. But they are much easier to install and can be reused for years. I would not buy more for the larger living room window but have decided to just put a window wrap kit on it."
