Most polymer-based foams have the ability to decrease thermal conductivity. Foam-Control MAX GPS is unique because it increases in R-value as the outside temperature drops. Foam-Control MAX maintains its ability to slow thermal conductivity throughout its lifetime resulting in a long-term R-value, unlike XPS which uses fluorocarbons as an expansion agent and experiences deterioration of R-value over time through a phenomena called thermal drift.
Foam-Control MAX GPS offers moisture resistance and permeability. The semi-permeable material allows moisture in the form of vapor to pass through the material giving the insulation drying potential. Foam-Control MAX GPS also offers up to 30 percent material cost savings compared to XPS. Foam-Control MAX GPS meets the performance standards of ASTM C578 and UL requirements.
Produced in three grades, 100, 150, and 250, this rigid foam insulation is ideal for vertical applications such as cavity wall insulation, precast concrete panel cores, wall sheathing, stucco and EIFS insulation. Foam-Control MAX is being produced in two of ACH Foam Technologies’ plant locations with plans to extend production to additional locations in 2017, allowing for shipping to any U.S. location.
