Work history with Perform Wall is literally from the ground up. It is the best ICF, concrete form system on the market. A green product 100% recycled polystyrene, (15% concrete & 85% polystyrene) cast form.
Great R: factor, stable heat mass, very adaptable for style change. New Mexico southwestern parapet style, contemporary (cast headers & columns) no exposed wood, pitched roof with wood trim on doors & windows, radius shaped walls strong and very sharp looking garden walls. The product does not require stucco mesh or pre-wire, the rough surface of the block is the form, sheathing, and plaster surface. My love for this product is real, I've been building custom homes with perform wall exclusively since 1997 and 25 years prior experience with similar products.
