Reviewed pricing, lead time, freight, and final configuration are confirmed during quote review before order release.
The insert frame drops into a sound existing opening without disturbing trim. Both sashes tilt in on constant force balances and lock with dual cams. The triple pane insulated unit posts a verified 0.21 U-factor, 0.16 solar heat gain, and a DP60 design pressure with ENERGY STAR certification in northern and southern climate maps; a dual pane Low-E argon build is offered where budgets lead. A factory Hunter Green exterior over white interior serves period exteriors without site painting.
