BuildBlock ICFs have an R value over R-22 and a performance value between R-45 and R-55, but sometimes customers demand something greater.
BuildBlock created ThermalSert and ThermalSert KD to service that need. The ThermalSert product is added to each course of block to the inside of the outside wall. This foam insert adds an additional 4.2 R’s per inch of foam used, creating even greater insulation.
Using the BuildLock Knockdown product creates the same thickness concrete wall with more than 40% greater insulation at the same time.
