How much space do I lose if I install Insta-Panels® inside a basement?
The INSTA-PANELS® are 1-¾ inches thick giving an R-value of 12. Polyurethane foam is one of the best insulating materials, so INSTA-PANELS® give very good thermal protection from a relatively small thickness. INSTA-PANELS® can be installed between or on the studs, but as with all insulations there is concern with providing tightness between the insulation and studs.
