Wood storm windows are not generally considered a custom project.
What made this one unique was, that a storm window wasn’t really the end sought at all.
The impetus for this project stemmed from the south facing opening casting a harsh light into the living room, which for years was endured by the inhabitants who spent considerable time there trying to read or visit with folks.
So the question was posed, “was there something that could be done, short of replacing the original single-pane wood sash window?” And of course, the answer was yes.
The clients were shown myriad samples of various types of glass. Laying various types of Low-E glass panes over variations of gray-tinted glass panes, and holding the combinations up in front of the window from the interior, until just the right combination of glass was struck upon.
After we had our glass supplier manufacturer an insulated glass unit accordingly, we made a very custom wood storm sash to house the insulated glass unit with the low-E and the gray-tinted panes laid over each other & glazed the two components together.
This met the criteria of retaining the original 21-Lite sash, as could still be viewed from the interior, while substantially diminishing the harsh light that came through it.
