MP House Diary #5 - Windows

Windows and WRB

The choice of windows  was one of the most important decisions on this project. Large expanses of glass were used to break up the "box" architecturally while providing lots of natural light and bringing the outdoors in. The windows are Fleetwood thermally improved aluminum windows (Westwood and Kona window wall). One of the few aluminum options left out there that can meet the energy code requirements and have the testing to prove it.

The weather resistive barrier (WRB) is a breathable product called Vaporshield "Reveal Shield". This version is black because we are doing an open rainscreen siding installation. The Vaproshield is folded into the openings and adhered with a liquid flashing to create a full protected opening. Windows are set on metal pans to further protect from water intrusion and allow proper weeping to occur.

Fleetwood "Kona" window wall system. Thermally
improved unlike a storefront system and has nailing flanges
so the building wrap can be integrated into the flashings.
Now that is a wall of glass!
