Does Low-E window film work? Heat-blocking, low-emissivity (low-E) windows and films both work to reduce your heating and cooling bills by blocking out UV rays. They also prevent the general transfer of heat. That means that you’re preventing heat loss in the winter and stopping heat entry in the summer.
Is Low-E coating worth it? Absolutely! Low-e glass options are definitely worth the investment. For just a few more dollars than standard glass, you get the energy savings and protection from low-e glass. And that little extra cost can pay for itself with the money you’ll save on utility bills!
Is Low-E good for windows?

How long does a Low-E coating on windows last? Weaver said that, based on what he has been told, “the newer low-e coatings are much more durable and more securely bonded to the glass than the older-generation low-e’s.” He said the sealant on the glass should last five to 10 years, and the coatings should outlast that by several years.
