EcoRenovator - View Single Post - Foil Faced EPS Basement Window Insulation

Ok, I've been at this a few days now (maybe 4 hours total) and have wrapped up the basement windows. The window with the solar panel duct penetrations was the most difficult but with measure twice cut once mindset I did pretty well. I needed to shave 1/8" off of the top and one side of a duct. Second try fit perfect.

This window by far had the worst cold air infiltration.

Before. Note frost buildup to the left of the ducts along window edge below centre.

After second test fit. Silicone is next. I needed to extend a cut to the left of the ducts to get enough 'give' to get over the ducts. I will cover this with aluminum tape.

Detail around ducts.

I will do a leak test in a few hours when there's a good skin on the silicone and see if there's any cracks I missed.
