Window Insulation for Summer Heat, Reflective Insulation Roll 48 in X 10 Feet, Double-Sided Aluminum Foam Core Radiant Barrier Kit with Tape for RV Windows Garage Door

Such a life saver for the texas heat. My bedroom window is the magnet of all texas sun light and heat. This has not only blacked out my room just how I love it and allowed me to finally have a cold room that requires me to use a blanket at night. Way better option then buying the cling on blackout for windows. Extremely easy to put in and tape down. Would recommend this for anyone needing to blackout a room and cool that room off.

This has been a game changer to control the heat coming from the front 3 van windows. Easy to cut. Rolls up when not in use. Flexible to work withHighly recommend.

I live in an apartment that used to be an attic. Poor insulation and I melt every summer and freeze every winter. I put some of this in the skylight of my bedroom and in my kitchen windows and it’s made such a big difference. My expectations were very low so I am very happy with the results. The weather here is getting hot and it’s comfortable in all rooms. I also would normally have three AC’s running but only need one now since the cold air seems to be circulating correctly.

This was one big sheet. I used it to cover the house windows from the cold weather. It did work for heat retention. had to cut it to fit my 3'x3' windows. able to cover 3. The velcro sticky's worked well.

Es buena

It’s advertising shows and says it’s in a “roll” but is actually folded up and creased. Not as advertised!

Works well! Def insulates & keeps our space cool. Needs it to reflect some early morning sun in the office. It’s a quick fix for those warm bright sunny mornings.

Extremely happy with this! Just what we needed for a southern facing window in our converted garage.
