I am considering using Tiger Foam on our central air heating duct work to keep more heat in the forced air. The basement is unfinished with walk out and the exterior walls have R23 Roxoul insulation. The basement will get colder once the duct work is insulated.
Are there any risks to cutting down indirect heating of the basement through exposed duct work. Could the basement become too cold for water pipes etc. I am located near Toronto Ont so the winters temps do drop to -25 Celcius or -10 Fahrenheit.
