Today, one of the biggest thing that was on my mind was how to trim the windows. We had already installed the corner trim, basically an “L” that extended beyond the siding for the two walls its connected, but we still needed to find a solution to trimming the windows. With our limited amount of Richlite, our initial idea was to mimic the “L” at the corners and only use two pieces of Richlite per window edge, yet we soon found a problem in this. It would work on the interior but the exterior needed to show the super insulated window frame detail. We finally decided to use three pieces on the exterior, creating an “L” where the window opening meets the siding to maintain the same detail as the corner, then the third piece would close in the insulated chamber around the window frame. The three images show the original super insulated frame detail, the window opening, and the start of this trimming process.
