Basement block foundation wall insulation
I have been auditing & retrofitting homes as an additional service to my remodeling company for 3 years now. My all-star insulator sadly passed away recently and I am just getting started with a new provider.
This new provider has specified Polypropylene Scrim Kraft to insulate unfinished basement block walls:
Thus far, I have used Thermax on my projects: 2″ foil faced poly-iso. He indicated that the PSK (Polypropylene Scrim Kraft) is cheaper, also satisfies the code for fire, and has a white finish which looks better. The JM product is formaldehyde free.
The 2 products have very close thermal values and I suspect will perform similarly when taped at seams and installed continuously.
My concern is moisture and durability.
I look forward to your input.
Thanks in advance.
