Wood Windows

Northwest Heights, just north of Forest Heights. An area well known among those who know such things, as an area where doors, windows and exterior envelopes are sorely tested by the storms that blow in off of the southwestern pacific ocean.

Two back facing Weathershield wood-clad casement windows in our clients home, are among the many openings facing southwest along this ever increasingly populated hillside.

The insulated glass in both sash had lost their seals, causing the stereotypical moisture to form between the double panes…what many folks refer to as the glass “fogging-up.”

As with almost all modern wood windows today, the muntins are merely a simulation of a true-divided lite sash. Each sash only has one large insulated (double-pane) glass unit in it.

Often, we can still replace the glass, removing the muntins which are adhered directly to the glass & reinstalling them onto the new glass. But given that the original glazing had failed, translating into some water-damage to the sash, which is likely what also…

…translated into these glass-seals to fail, it was determined that we would just order new sash from Weathershield.

As you may or may not be able to tell from these photos, this particular window assembly is referred to by the industry as an OX assembly. One sash is non-operable, or what they call a picture casement window,…

…while the other sash is a crank-out casement. In the previous photo, Tim Afonin is shown transferring the hardware onto the new sash, which is the operable of the two sash.

After reinstalling both replacement sash, Tim masks off around the seams of the non-operable sash…between the sash itself and its surrounding jamb assembly and then fills the reveal (space) with silicone caulking to protect the opening.

More and more folks are asking us to do this on openings with such extreme exposure to such extreme weather. Thanks to fellow technician Steve Hilt for taking some good photos here.
