Understand Windows & Their Performance With Structural Insulated Panels

The performance of the panels, the insulation and airtightness can offset the comparatively lower R-values of windows, feature glazing and sliding doors, but on the other hand the solar gain can be too high, due to the lack of good shading options. Should you decide to go for a style with a lot of glass, it is prudent to look for better performing windows with triple glazing — especially if you are aiming for a Passive Haus ora low energy home.

Words by SIPS Direct

Rod recommends creating a sun study to avoid too much solar gain to prevent the house from overheating. There are limitations to how far the SIPs can span without extra support. Please discuss this matter with your architect. "Unfortunately, many new standard houses are built with lots of standard double-glazed windows and it becomes a weak point in their thermal envelope, which creates that coldbridge which can increase your heating & cooling bill." says Rod.
