The windows utilized in this project were manufactured by PELLA. They are double insulated LOW-E glass, clad on the exterior and wood, which were painted to match the interior trim on the inside.

You should review your project with your builder, or find the PELLA supplier which offers the windows and sliding glass doors. This is the manufacture which supplied the produce on this project.

The exterior surround : window outside frames, perimeter trim and sills were constructed with AZEK, a solid plastic product which was primed and painted. All in all, a group of fairly low maintenance product, but not at the low end of the price for windows and trim.
