What is a Pinnacle Picture Window? 

A picture window is fixed - it doesn't open. That means no moving parts, no air leakage, and an unobstructed view.​

​

We use them to frame lake views, brighten living rooms, and pair with casements or awnings for ventilation. Every Pinnacle picture window is custom built with a foam-enhanced, fusion-welded frame. 

Why Homeowners Choose Our Picture Window

  • Superior energy efficiency - fixed design means lowest possible air infiltration

  • Dependable strength - fusion-welded sash and frame with no screws to loosen

  • Foam-enhanced frame - honeycomb vinyl filled with foam for year-round comfort

  • Energy Star 7.0 glass - LoE 270, 360 and Neat+ self cleaning options
