EPS Foam Significantly More Energy Efficient Than XPS

There are many reasons BuildBlock ICFs are the premiere ICFs on the market, our use of EPS foam is one of those reasons.        As reported by Concrete Construction, “what makes EPS and XPS different is their manufacturing processes. EPS uses steam and the blowing agent pentane to expand polystyrene resin beads and subsequently mold them into blocks, which can later be cut to size. XPS, on the other hand, processes melted polystyrene resin through an extruder and expands it, using blowing agents. There are key differences between EPS and XPS—most importantly, moisture resistance, environmental impact, long-term R-value, compressive

ICF Construction Tip: Bracing

Key to any ICF installation is a bracing and alignment system to keep the walls straight and plumb during the pour. One of industry partners, Fab-Form, has created an updated Zont ICF Bracing System that gives you a light weight, cost effective method of bracing Insulated Concrete Form wall using site available 2x4s. The Zont ICF bracing system consists of three components: Zont Waler Brackets: hold horizontal 2×4 walers and vertical 2×4 strongbacks solidly against the ICF wall. Zuckle Wall Aligners: plumb the strongbacks to align the wall to the stringline. 2×4 Walers & Strongbacks: held in the Zont bracket and
