ACH Foam Technologies Solves the Water Absorption Equation
WESTMINSTER, Colo., June 19, 2018 (GLOBE NEWSWIRE) -- Foam-Control® PLUS+® has demonstrated water absorption max volume results of 0.3% in laboratory testing proving that ACH Foam Technologies’ molded foam insulation resists moisture absorption as well, or better than other rigid foam insulation on the market. Molded polystyrene’s ability to quickly dry after wetting conditions contributes to R-value retention over the building’s lifecycle. Foam-Control® PLUS+® performs better, is less expensive than extruded foam insulations (XPS), is backed by ACH Foam Technologies’ 50-year R-value warranty and available in a wide range of thicknesses. Foam-Control® PLUS+® is used in perimeter, under slab, plaza decks, green roofs, commercial roofs, cavity walls, and EIFS applications where moisture exposure is common.

“All rigid foam insulations absorb water in wet conditions,” says Frank Kiesecker, Vice President of Sales & Marketing at ACH Foam Technologies. “Science; however, proves in everyday use, and now in laboratory testing that molded polystyrene dries faster and retains R-values better than XPS.”
“Previous testing didn’t account for a wetting period followed by a drying period, which is reality,” shares Todd Bergstrom, Ph.D., of ATZ Laboratories. Bergstrom's C272 testing methodologies include air drying wet samples at 72 degrees F and 50% relative humidity for 24 hours before measuring water by volume. Foam-Control® PLUS+® water absorption max volume results of 0.3% with the drying-period is identical to XPS' results. This methodology reflects the realities of buildings and infrastructure being subjected to normal wet and dry weather conditions.
After 15 years of service as below-grade vertical wall insulation, molded polystyrene and XPS sections were removed from a building in St. Paul, MN for testing. MPS weighed in at 4.8 percent water by volume, while the XPS was an astounding 18.9 percent water by volume. Molded polystyrene’s ability to release water after rain events and XPS’ propensity to trap moisture is evident. In these real-world conditions, molded polystyrene retained 94 percent of the originally published R-value. The XPS product’s R-value was 2.6 per inch, just 52 percent of original published R value.
“Foam Control PLUS+ permeability and drying potential always outperforms XPS in the field,” says Kiesecker. “This is now also validated by laboratory findings.” Along with the superior performance, MPS costs less per R and per inch of thickness than other rigid foam insulations. Foam-Control PLUS+ is face labeled, scored, comes in 15, 25, 40 and 60 psi grades and can be manufactured in many thicknesses with a 50-year warranty.
