Asure windows are designed to maximize the amount of daylight entering the home while offering improved energy efficiency. When ordered to meet regional Energy Star criteria, U-factor and solar heat gain coefficient (SHGC) both drop, while visible transmittance stays strong.

In addition to energy efficiency, Asure windows feature a two-stepped sill design for better resistance to water and air infiltration. The patented Lap-Lok meeting rail and thick fin seal weatherstripping also help ensure a tight seal against wind and rain. On the exterior of the window, a stylish classic stepped design boosts curb appeal. Inside, a constant-force balance system means the sash requires minimal effort to operate. Choose from a range of colors and grid styles. Simonton | 800.746.6686 |
