Peerless Fixed Windows for Energy Efficiency

Peerless Fixed Windows are some of the most energy-efficient windows available in the market, with a U-value range of 0.14-0.31! The fixed windows work great all over the nation, from low rise to high rise buildings. Multiple units can be assembled into one master frame at the manufacturing facility, saving time on labor in the field. An optional flange or integral trim design can be co-extruded to make installation in the field efficient and less costly. Low-E coating on the glass with heat absorption powder finish will keep you cool in the summer and warm in the winter no matter where you live. Pair our Peerless fixed windows beside an inswing operable window to gain fresh air and the ability to clean from the interior of the building.
