The Regal Guardian 365 provides the ultimate in energy efficiency through a variety of technologically advanced features:
Utilizing a triple seal, as compared to the typical dual seal, minimizes air infiltration.
With 7/8” of dead air space and double strength glass, the Regal Guardian 356 keeps the home comfortable all year long.
This unique patented design with warm edge spacer minimizes conductivity and condensation, provides superior argon gas retention and exceeds Energy Star requirements.
Unlike traditional Low E glass that has one coating on one glass surface, the unparalleled UltraFlect glass packages uses two different technologically advances reflective coatings on each of the two pieces of glass. The coatings are aligned to maximize thermal performance and reflectivity.
The clear appearance of this innovative insulating glass system permits 64% of the sun’s natural light to enter your home while blocking 72% of its heat energy. This tremendous energy efficiency reduces heat loss by nearly 50% and cuts summer cooling costs up to 25%. The Regal Guardian 365 double hung window with insulated frame and sash, combined with the UltraFlect Glass Package and Triple X Heat Shield, has a U-Value of .22, R-Value of 5.0 and SHCG-Value of .18 – exceeding all NFRC and Energy Star requirements.
