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.
