Windows are usually the weakest point in a home's thermal envelope, and film addresses that without the disruption of replacing glazing. By reducing solar heat gain through the glass, film can help rooms stay more comfortable through the warmer months and ease the load on air conditioning during long sunny spells in Connecticut. The same films also absorb ultraviolet light and cut glare, which makes screens easier to read and interiors slower to fade. What suits your home depends on the glazing you already have — single, double or coated units all behave differently — so identifying the existing glass is the first step. A Kepler dealer can review the windows, explain how each range would perform on them and set out the options before you commit to anything.
