Our exclusive AC Master, or all climate, Glass System is designed for homes in which cooling costs are relatively high in the summer and heating costs are relatively high in the winter.

AC Master is highly effective in reflecting outside heat energy away from windows and doors. Using our AC Master Glass in your vinyl replacement windows keeps cooling systems from running as much, reduces uncomfortable warm spots in your home and actually blocks almost 80% off the damaging UV rays that fade your carpet, draperies and furniture. In warm weather, your cooling system runs less because AC Master reflects outside heat away from your windows while still allowing light in. AC Master makes the glass in your replacement windows nearly three times more energy efficient than standard single glazed glass! It is actually one of the most efficient double pane glass system on the market today and will actually even out-perform most heat mirror systems.

AC Master consists of double insulated glass, with two low-emissive (Low-E) coatings, the PPG Intercept System and argon gas fill. It is especially recommended for energy efficient replacement windows and doors in warm-climate areas.

Argon is a safe, stable inert gas that is inserted between the glass panes of the energy efficient replacement window to improve its insulating properties and help reduce your energy costs. Argon makes your replacement windows more efficient because it's better than air at reducing heat transfer between the inside and outside.

PPG Warm Edge Technology Spacer System is a highly advanced tin-plated steal spacer system that separates the glass panes in your new replacement windows and doors. It plays an integral role in making you more comfortable in your home and lowering your energy costs. Its unique one-piece U-channel design creates a strong thermal barrier that reduces heat loss. Intercept incorporates what's known as warm-edge technology to help maintain a uniform temperature throughout the glass and reduce the likelihood of condensation.

Regency Windows with the AC Master glass system are Energy Star Compliant.
