thanks Pat! There are two windows directly under my sons room, and i can feel the cold from them on his harwood floor. The cost of our first heating oil deliver this year was shocking, so a solution that is inexpensive, that I can do myself is worth a shot! I appreciate the video and look forward to trying this today.

Doesn't this defeat the purpose of the window?
Remove the window and have almost no energy loss.

Pat - good thoughts about improving the insulation value of basement windows. Another solution that will not require adding insulation would be to use a glass block windows (with or without an air vent). This window will improve the insulation value and still allow natural light into the lower level (and you can even get fresh air if the basement has any bad smells).

Most polystyrene insulation has a value R-4 to R-5. It is not likely that this is actually R-6.5 per inch unless he is using a polyurethane, which deteriorates over time losing R-Value. Best is to go with a 2" and get at least R-10.

You could use a heat shrink film, that would keep the draft out. No R-value added though.

Pat.....you are a true rock star of home improvement!!!!! Keep it up brother!
p.s what about a piece of batt insulation tucked into the cavity if the sill is big enough? What do you think?
