If a window isn’t installed properly, it won’t matter how energy efficient it is.

 

Installing windows on a building with exterior insulation isn’t easy.

The window and the rigid foam or mineral wool need to line up on the same plane for good drainage, proper cladding attachment, and to prevent compression of the insulation. 

Rough openings have always been the weakest spot on any building for air and water infiltration, and “bumping” the window out only makes it more difficult to achieve a good air and water seal.


Traditionally a wood buck is built to extend the mounting point of the window to create a flush plane. But wood can rot, warp, and shrink over time. Wood is a poor insulator, allowing thermal bridging around each window and door. Not only does it reduce the energy efficiency of the building, it causes condensation to form, and potential damage from moisture – which can lead to extensive repairs.
