Out of Sight, Not Out of Mind: Specifying thermal insulation below-grade and under-slab

Balancing performance and cost for insulation installed on below-grade foundation walls and under floor slabs can require specifiers to rethink common assumptions about rigid foam insulation. Misperceptions about the moisture absorption of expanded polystyrene (EPS) compared to extruded polystyrene (XPS) may be limiting more cost-effective choices. Test results demonstrate the long-term durability and moisture resistance of EPS insulation and the stability of its thermal performance. In many applications, substituting a strong and adequate, yet lower compressive resistance insulation, can result in significant cost savings.

Specifying ‘Greener’ Concrete Infrastructure

The use of rapid-setting calcium sulfoaluminate (CSA) cement reduces the amount of energy and carbon dioxide emissions associated with portland cement production. It also requires less limestone—the primary source of carbon dioxide released during the chemical sintering process. Consequently, the material can play a significant role in improving the sustainability of construction materials by simply reducing the quantity of non-renewable resources used during manufacturing. The use of resources is just one part of the equation. Durability—or lifecycle—is the other.
