THE INSTALLATION OF PASSIVE HOUSE WINDOWS
INSTALLATION OF THE WINDOW
While the installation of a window is project-specific, for certification purposes three scenarios with the window installed in Passive house suitable walls must be considered. This gives the opportunity for like-for-like comparisons between windows.
The installation detail matters because there are additional surface areas at the junction between the wall and the window and often there is more structure needed in the wall. This means there are additional heat loss areas in the window reveals and there is less wall insulation due to the additional structure.
The recommended installation detail includes wall insulation covering some of the window frames to further mitigate or eliminate heat transmission through the frames and the window reveals. This isn’t the only way to detail the installation of a Passive house window though. And it should be noted that insulating over the frame doesn’t have any effect on the performance of aluminium clad windows.
Window sills are not so easy to insulate and usually the heat loss through the sill detail is worse than through the reveals and head detail. The different details each need to be accounted for in the Passive House Planning Package. It is that detailed.
THE INSTALLED WINDOW U-VALUE
A Passive House certified window U-value is not the actually U-value that a project will actually have. It is a value that allows for like-for-like comparison. And it provides critical information to use when inputting the project-specific details into the Passive House Planning Package.
The installed window U-value takes into account the dimensions of the window, the glass, the frame, the installation details, the U-values of the glass (center pane) and the frame, and the Psi values of the glass spacer and the installation detail.
For a Passive House certified building the required U-value is climate dependent. In the US and Canada, it must be less than 0.85 W/(m2.K).
A Passive House certified building does not require Passive House certified windows. However, if the window isn’t certified it can be more difficult to track down all the necessary and correct information about it.
