6pcs Window Grille Inserts Grid Kit,40ft Window Window Grid Kit Self-Adhesive Peel and Stick Trim Window Grille Inserts Flexible Molding Trim for Window Frames, White

I had no problem applying these to the outside of my windows in 30°F weather. They look good and so far have stuck just fine. I'll update my review if they peel off later. Update: reduced from five stars to one. Three days later and one piece of the grid has fallen completely off and several others have begun to peel off at the ends. I will be trying to return the unused rolls.

I have always admired windows that had these grids on them. This was perfect for a DIY project so easy did not take long at all and they stick on very well. Look great from the inside and outside, highly recommend! I loved it so much I ordered more to do my back sliding doors off my deck! Can’t even tell it’s stick on!

This product does not work the way it is described. When measured and cut to fit the length or width of my windows it shrunk and then the ends would unattach and curve out. I could not get it to stick. The adhesive is good but not good enough to hold on to the window at the cut end. I tried different things including straightening out the roll prior to putting it on the window. Sadly it just doesn't stick. Going to see if I can find a product that actually does work.

Added these to my bay window…game changer! I now like the window!
