One of the areas the blower door and infrared camera test highlighted as a deficiency was around the windows. In-fact, the windows looked better insulated than the gap between the window frame and opening!

So, I set out to remedy the problem. As you can see from the image below, the area between the window frame and opening were fairly well foamed. I touched this up a bit to ensure it was fully foamed with now gaps and then trimmed off any excess

From there I utilized Siga Corvum tape, which is pre-creased, to seal the window frame to the opening.

I carefully applied the tape around the entire frame ensuring it was firmly adhered. The final result is a neat install that will ensure no air or moisture leaks around the window opening.
