Review on Gila CS78 Glare Control Smoke Film - 36 x 6.5' Window Film, 36-inch x 6.5-inch by Milton Wolf

I put this product on all my windows. Double glazed windows require it from the outside, otherwise it will damage the window. All double glazed windows are fitted from the inside. After all my windows were closed, it was 62 degrees Fahrenheit inside my house while the outside temperature was 78. I couldn't be happier! No more electricity bills in summer! I didn't use the recommended solution, I used Dawn dish soap and water. First I washed and rinsed the window, then applied more soapy water to the window, hung an anti-reflective sheet, squeezed out the excess solution and smoothed out the creases. If you're doing this on a warm day like me, you'll need to apply more soapy water as needed. Practice makes perfect, as the saying goes. I leave all year. In winter, windows feel warmer on the inside, which is an added benefit for heating your home. After using this product, you can easily see through your windows. Measure and cut the product to fit, leave on the backing paper until ready to hang, this works best. For large windows you need an assistant.
