Healthy Concrete Systems: Defending design intent


Construction documents need to be clear, concise, correct, and complete—but is this enough to fend off the twists and turns of executing the contract for construction? One may begin with the very best in design intent, but it is the responsibility of the entire project team to understand and adhere to this in order for it to become a reality. Too often, some of the team members will alter the intended design to accommodate their own business advantage.

Drywall is often misperceived as a building material that does not demand the skillful manipulation of a traditional construction material. However, anyone who has worked with drywall knows the product is not so cooperative.

Selecting Polystyrene Foam Where Moisture Exposure Occurs


The purpose of building insulation is to reduce heating and cooling energy consumption, contribute to durability, and provide comfort for occupants. However, there are numerous locations where significant exposure to moisture—which severely affects a material’s thermal performance—occurs, such as in protected membrane roofs, vegetative assemblies, below grade, and frost-protected shallow foundations (FPSFs).

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.
