This case study covers the window installation of 4 HeatShield 5000 Max 3 High Performance Double Hung Glass Windows in a breakfast nook in Garner, North Carolina. The package had triple pane glass, argon gas fill, a stainless steel warm-edge spacer, dual Low-E, U-Factor 0.15-0.22, SHGC 0.20-0.28, and Gator’s lifetime product warranty. The goal was a more comfortable room and better energy efficient windows performance.
The breakfast nook got daily use. It also got strong light, heat swings, and glare. The old windows did not support the space well. The new double-hung windows kept a familiar look and gave the room a cleaner finish. The homeowner wanted less heat transfer through the window openings and better comfort in hot and cool weather. Energy use mattered too, a room with more than one window can affect nearby heating and cooling. Condensation control was another goal.
Site Check
A window contractor measured each opening. The team also checked the trim, clearance, and frame shape. This step helped the replacement windows fit the opening. It also helped the new units seal well.
