Windows and Doors
Windows and doors represent significant points of energy loss in a home. Their efficiency, or lack thereof, directly impacts heating and cooling costs, contributing substantially to your overall energy consumption. Addressing these areas with energy-efficient upgrades can yield considerable savings and improve comfort.Improving window and door efficiency significantly reduces energy waste. Older, poorly sealed windows and doors allow drafts to enter, forcing your heating and cooling systems to work harder to maintain a comfortable indoor temperature.
This increased workload translates directly into higher energy bills. Conversely, energy-efficient windows and doors create a tighter seal, minimizing air leakage and reducing the strain on your HVAC system.
Energy-Efficient Window and Door Selection
Choosing energy-efficient windows and doors involves considering several key factors. The most important is the U-factor (heat transfer coefficient), which measures how well a window or door insulates. A lower U-factor indicates better insulation. Also crucial is the Solar Heat Gain Coefficient (SHGC), which measures how much solar heat is transmitted through the glazing. A lower SHGC is better for reducing heat gain in summer.
Finally, air leakage is a significant concern; look for windows and doors with high air infiltration ratings (lower is better).
Energy-Efficient Window and Door Materials
Several materials contribute to enhanced energy efficiency in windows and doors. Double- or triple-paned windows with low-E coatings significantly reduce heat transfer. The low-E coating is a microscopic layer applied to the glass that reflects infrared radiation, keeping heat inside during winter and outside during summer. Frames made of materials like fiberglass or vinyl offer superior insulation compared to traditional wood frames, further reducing energy loss.
Solid-core doors, as opposed to hollow-core doors, provide better insulation and sound dampening. For example, a fiberglass door with a high-performance insulated core will perform much better than a hollow-core wooden door.
Identifying and Addressing Drafts Around Windows and Doors
Identifying drafts around windows and doors is relatively straightforward. A simple test involves holding a lit incense stick near the window or door frame. If the smoke is deflected, it indicates an air leak. Another method is to feel for cold air infiltration around the perimeter. Addressing these drafts involves sealing gaps and cracks with appropriate materials.
Caulk is effective for sealing larger gaps, while weatherstripping is ideal for smaller gaps around the frame. Replacing worn or damaged weatherstripping is crucial for maintaining a tight seal. For larger gaps or severe air leaks, professional window and door repair may be necessary.
