Comparing Polystyrenes: Looking at the differences between EPS and XPS

bigstock-Apartment119457272

Insulation is a critical component to specify when designing a functional, cost-effective, and energy-efficient building. One method to insulate a building is by installing 50 to 152 mm (2 to 6 in.) of rigid foam insulation on the exterior side of the wall framing. Two of the most frequently installed types of rigid foam insulation are expanded and extruded polystyrene (EPS and XPS).

Integrated contract administration and acoustics

9564-06 copy

Buildings are a combination of design and construction. On paper, it may all seem to flow and make sense, but a small change in the former can have major impacts on the latter. Similarly, alterations that happen during the construction phase can end up causing significant design problems, affecting everything from acoustics to ambient noise.

Thermal efficiency in glazed curtain wall systems

Curtain Wall Feature Image

With glazed façades dominating urban landscapes, the strides made to improve the energy efficiency of glass are well-documented and generally well-understood. However, much more quietly, the framing members of wall and window systems have also been re-engineered. The performance improvements in these less-discussed components are poised to add up to big gains in efficiency.

Updating code conforming wood designs

OneNorth-Radiator-JoshPartee-0713

Designing large buildings with wood offers distinct design options typically not found in other structural materials, along with advantages in economics, energy efficiency, and other sustainability factors. However, building codes and standards are often perceived as too complex for designers and builders, so many provisions that allow for wood use in construction are seldom realized.
