Reflective Films, Tints, and Coatings: Pros and Cons

Are you thinking of getting new patio doors in Roseville CA? If you are, you should consider getting a patio door from Renewal by Andersen of Sacramento. Why? Because the patio doors they offer are not just pleasing to the eyes, they are also made to improve your home’s energy efficiency.

Renewal by Andersen of Sacramento is proud to say that we offer windows and patio doors with advanced materials like Fibrex and Low-E4 glass. We all heard about the Fibrex technology that provides toughness and durability to your windows and doors, as well as ensures a tight seal that traps the heat or the cold within your home.  But what about the Low-E4 glass that we use on our products?

Well, for starters, most replacement door and window manufacturers use reflective films and tints to improve their product’s performance. Yes, reflective films really do block much of the radiant energy striking a glass—keeping occupants cooler—but the problem is they also block most of the visible light. Because only minimal amount of light can pass through your tinted windows, occupants tend to use more electric lighting to compensate for the loss of daylighting, which, for us, destroys the purpose of providing homeowners a way to save energy.

Low-E (low-emittance) coatings, on the other hand, are more versatile than either reflective films or tints and are virtually invisible. It uses microscopic metal or metallic oxide particles to suppress radiant heat flow out of the window and can be formulated to allow varying degrees of solar radiation in. This only means that Low-E coatings help in keeping your home cool during hot seasons and warm during cold seasons without obstructing your view as well as the natural light from entering your home.

It is for this reason that Renewal by Andersen uses the Low-E4 coating on our products rather than using films and tints. From our awning windows in Sacramento to our hinged French doors in Roseville CA, all have been treated with Low-E4 coatings to provide outstanding energy-efficiency without a hitch to our homes.
