Windows

Windows are an essential factor in assuring pleasant indoor conditions. In cold climates, poorly insulated windows will cause relatively cold surfaces at the facade and will require active heating near the windows to compensate for cold air drops, draughts and “cold radiation” caused by the cold surfaces. Highly insulated windows, on the other hand, will make an active contribution to increasing the level of comfort. High performance windows, specifically developed to meet the requirements of Passive Houses, are offered by an increasing number of manufactureres across the globe. A list of PHI Certified Passive House windows can be found here.

Passive House windows allow for major energy savings and offer a superior level of comfort.
