Heat Mirror Technology & Thermal Performance
Up to 70% of energy loss occurs through
windows and doors, with 90% of window heat loss occurring through the glass. One of the most significant
energy saving developments in windows today is a revolutionary technology called
Heat Mirror®.
Heat Mirror is a low-emissivity coated polyester film that is suspended inside an insulating glass unit. Invisible to the naked eye, this revolutionary technology reflects heat back to its source. In the winter, it reflects heat back into your home, keeping your home warmer. In the summer, heat is reflected off the outside of the window, keeping your home cooler.
Stanek windows manufactured with Heat Mirror film will
turn your window into a sophisticated climate controlling device — able
to block heat transfer through the glass, achieving energy performance
from your window nearly 10 times that of single-pane glass and 5 times
that of ordinary dual-pane glazing!
Heat Mirror glass effectively blocks over 99% of UV
radiation from the sun, which prevents fading of furnishing, carpet and
drapes, in addition to reducing noise pollution for a quieter home.
HIGH-PERFORMANCE LOW-EMISSIVITY COATING WITH ARGON GAS
High-performance Low-E coatings are applied by a magnetic sputtered vacuum deposition process to ensure superior thermal performance. It achieves solar control with the insulating performance and comes standard with argon gas.
HEAT MIRROR® TECHNOLOGY
Heat Mirror technology upgrades glass systems by suspending a reflective solar film inside the glass unit. This creates a superior multi-cavity glass unit without added weight. Argon gas is standard in both cavities with an option to upgrade to krypton gas.
