Fuel Saver Special
Low E is a transparent metallic oxide coating applied onto a glass surface. The coating allows short-wave energy to pass through but reflects long-wave infrared energy, which lowers the U-value and that means more energy savings. An odorless, colorless, tasteless, non-toxic gas, argon is six times denser than air. It is used to replace air between the glass panes to reduce thermal energy transfer and heat loss.
ClimaGuard glass has heat reflective coatings – microscopically thin layers of metal and metal oxide that filter energy by keeping warmth inside in winter and outside in summer.
A patented radiant glass technology that produces thermal energy, R-Series technology provides transparent insulation by creating a perfect thermal barrier between the building envelope and the exterior environment, and can also be used as a primary or auxiliary heat source.
