ZEALOTT Heat Rejection Window Glass Tinting Film for Residential and Commercial Uses, Sun Blocker, Solar Guard, 23.6-Inch by 6.5-Feet (60cm x 2m), Light Black

Very easy to work with. I have tinted 20 sash windows in my child care center with this and it looks amazing. No high heat coming in, cuts down on the view into the building and yet allows the children and staff to see the outdoor playgrounds clearly.

Will not stick on the window

It’s not dark. You can still see inside.
