VINYL BOW & BAY WINDOWS

Interstate's Bow and Bay windows elegantly add light and sun to any home.
ENERGY EFFICIENCY

Our products and processes emphasize energy savings – and that means we consume less energy to minimize the CO2 released into our environment.

Our buildings save energy by utilizing in-floor radiant heating during off-peak energy hours and by using motion controlled lighting.

Our processes conserve resources – like filtering and reusing glass wash water for glass rinsing, and recycling our vinyl and glass scrap created during the fabrication process. And of course, we have a recycling program for metals, cardboard and paper.

Interstate belongs to a voluntary energy cooperative that monitors and helps reduce energy usage during times of peak demand. We are helping to protect our community from blackouts, to keep energy rates stable and to help the environment by reducing reliance on peaking power plants.

Climaguard™ Low E Glass and Argon Gas Add Comfort and Energy Savings

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.
