What are they made of? How much does it cost? Specialty products like this are usually expensive compared to something standard like fiberglass bass insulated stud walls with drywall.
Could be an advantage in an existing home where the doors/windows/floor are already trimmed out (product looks thin but very hard to tell). But if thin it can't provide much insulation. Can it be easily/cleanly taken down if needed? Are your basement walls in good shape and already moisture treated (lawyers don't let contractors use words like "waterproof"). Is the yard outside sloping away, well drained, and/or sand/gravel? (Why invest if the basement is prone to get damp/wet?)
When we built 12 years ago with a finished basement (in clay - yuck) we graded the site to drain away from the house, gravity drained the footing drains 80 feet downhill from the house, used 2 foot overhangs all around, put tar on the outside of the poured concrete walls (way better than block walls), backfilled with pea stone, surrounded the house with landscaping fabric/stone, surrounded half the house with a deck, put 6 inch gutters everywhere (bigger than normal), and replaced the standard downspout kick outs with drain tile to move the water 40 feet downhill from the house.
