An old farm house in what is now known as Northeast Portland. And yes, you may see this same house shown in another vinyl window project listed in this catagory. Our client had us come back in 2013 and replace some original wood casements with Vinyl Single-Hung Windows.
But back to this project. Original putty-glazed single-pane wood windows do not offer much in the way of insulation.
Especially when the house itself lacks any modern day levels of insulation in the walls, floors or ceilings.
The custom aspects of these windows come in two forms.
The first is the unusual configuration. Picture over awning over picture.
Due to the shelving structure that was to sit to the interior side, the operable windows had need to be somewhat elevated.
The second somewhat unique quality of these windows comes in the form of the MIRROR-GLASS, sometimes referred to as one-way glass. It pretty much makes it impossible to see in from the exterior during the daytime.
Although it still allows a view from the interior. For those who have need for the privacy and/or security, this can be a nice, albeit somewhat expensive option.
