Foam-Control® PLUS+® from ACH Foam Technologies adds efficient value to a high-performance building

WESTMINSTER, Colo., Oct. 03, 2017 (GLOBE NEWSWIRE) -- Calacci Construction strives to self-perform the critical path of their work, generally placing concrete and setting steel along with managing framing, roofing, and insulation for all their projects. When it came time to construct the company’s new offices, Calacci’s appreciation for long-term efficiency was the driving factor in the decision to invest in a high-performance thermal envelope insulated with ACH Foam Technologies’ Foam-Control® PLUS+® architectural insulation.

Foam-Control® PLUS+® 250 scored architectural insulation, provides an R-value in the mid-20s on Calacci Construction's new building.

“We wanted a good, tight seal on the building,” says Calacci Construction owner, John Calacci, of his company’s new 15,800-SF office building. To achieve the desired energy efficiency, Calacci’s new building integrates a geothermal heating and cooling system with a high-performance building envelope. Achieving a tight seal on a building that combines a glass curtain wall with punched window masonry required a bit of precision in materials and workmanship, leading Calacci to choose Foam-Control® PLUS+® architectural rigid foam insulation. The building’s masonry face lifts out and dips in and around, long vertical sections of glass with some wall cavities presenting 6” of void space, while others were just 2”.

Working with their local White Cap representative, Calacci purchased 19,200 board-feet of Foam-Control® PLUS+® 250 scored architectural insulation. Foam-Control® PLUS+® is designed to give architects, designers, and contractors the strength, energy efficiency, and moisture resistance of a high-quality insulation at a budget-friendly price. Purchasing a pre-scored product allowed Calacci’s installers to easily create custom lengths simply by bending the insulation board along the perforations and snapping it into pieces.

Though many of the sustainable strategies Calacci employed are common place, one application was a first for them.

“We figured out how to embed two inches of ACH Foam Technologies’ Foam-Control® PLUS+® insulation within a cast-in-place concrete wall,” says Calacci proudly. Calacci used two steel rebar grids and center-facing slab boosters to sandwich a layer of Foam-Control® PLUS+® into the formwork to create a 12”-thick Symons pan-wall. “We’ve created a thermal break along the foundation walls that extends up four feet above the floor, but without any caulk joints to maintain as you would with insulated precast panels.”

While doing it all alone is generally a thing of the past in commercial construction, it’s good to know there are still a few old-school builders out there putting their own new twist on the way things get done.
