In connection with Hurricane Preparedness Week (May 21-27) my blog host is promoting a PINK insulating product that helps build very strong walls. My friends the Three Little Pigs should love it; not just because the system is PINK but because walls made with the system can withstand some of the strongest huffing and puffing a hurricane is likely to produce. The Fold-Form® Insulating Concrete Form system is made with interlocking form blocks of expanded polystyrene insulation. The blocks are pre-assembled with folding Spacer Ties. Fold-Form blocks have an insulating value of R-18 by test and the insulating value of finished walls can be in excess of R-23, depending on the concrete wall thickness and finishing materials selected. Online information about the product shows how energy efficiency can be even better. If you don't already know about this energy efficient and strong building system, check it out.
