High-performance windows for New homes
Be cautious with large glazing areas. Do not let yourself be fooled by ideas of "enjoying the nature's beauty", or "spectacular views", and so on... Be practical. Do not forget that windows are a weak thermal point in any home.
We need the daylight and the solar heat gains that windows provide, but we should not forget that they are a major cause of unwanted heat loss, overheating, and glare.
So, do it right the first time.
If you are about to build a new home, consider carefully the size of your windows in each side of the house, the type of windows and also factors involving its glazing and frame elements, and the details that define their energy efficiency.
Selecting The windows
The best size for windows vary with the climate and the side of the house where they are going to be installed.
See: Window sizing and Windows for cold, hot and mix climates
When selecting windows, take into account....
- their energy coefficients: see: Window Energy Rating Labels.
- Prefer fiberglass-frame windows, or vinyl-frame windows. Aluminum is a strong, durable and non-corrosive material, but is also a highly conductive material. See: Window Frames.- Also prefer casement windows: the type of operation of the windows is important for air sealing or for natural ventilation. See: Casement Windows Performance.
Windows & Overhangs & Shade
Windows should be protected from the elements, as much as possible, according to your climate and the side of the house. Shading and overhangs and other design features are critical.
