ThermaProof Energy Saving Windows
By Energy Management
Serious Materials recently announced its new ThermaProof energy-saving windows. The new line of windows, for both commercial and residential construction, offer true, full-frame R-values of R-5 to R-11. These performance levels are up to four times higher than current Energy Star requirements and the company purports that they are the only windows that already exceed proposed Energy Star standards for 2013. ThermaProof windows claim to save more energy than any other major brand.
