Any operable window or door, even new ones, will have some degree of window air leakage.
Any operable window or door, even new ones, will allow some air leakage.
Testing measures window air leakage at 25 MPH wind speeds. The air infiltration rate must stay below 0.30 cubic feet per minute per square foot of window area. A 3 foot by 4 foot window can allow 3.6 CFM of air infiltration. At 50 MPH wind speeds, the wind pressure increases four times, causing more leakage.
Most new windows have an air infiltration rate below the 0.30 maximum. Several factors affect performance, including window size, location, building design, and terrain.
Multi-Pane Windows Reduce Air Leakage
Multi-pane windows provide extra insulation layers and lower pressure differences between interior and exterior spaces. Double-pane and triple-pane windows contain sealed spaces filled with inert gases like argon or krypton. These gases act as barriers to airflow, reducing air infiltration and improving energy efficiency.
Proper installation greatly reduces air infiltration. Sealing, caulking, and insulating the window frame help prevent drafts and air exchange. Energy Swing Windows ensures precise installation, reducing air leakage to minimal levels.
Frame materials also influence air infiltration. Vinyl and fiberglass frames insulate better than aluminum, which expands and contracts with temperature changes. These changes can create gaps that let air pass through.
Homeowners seeking better efficiency should choose multi-pane windows with high-performance ratings. Expert installation by Energy Swing Windows guarantees long-term energy savings and comfort.
The Value of Proper Installation
Proper installation plays a crucial role in minimizing air leakage and maximizing window performance. Even the best windows can underperform if not installed correctly. Precise alignment, sealing, and insulation are necessary to ensure optimal energy efficiency and prevent air drafts.
