Air within the envelope of a building is subject to air infiltration, exfiltration and the three modes of heat transfer: conduction, convection and radiation

UV damage is a real issue with real consequences, yet it’s an issue that often gets overlooked. Taking on this challenge, Dörken Systems Inc. introduces DELTA-STRATUS SA – the only self-adhering vapor-permeable air- and water-resistive barrier with a unique fourth layer for added UV protection.

Halo Exterra, a foam board insulation for above-grade exterior insulation applications is also designed to be a water-resistive barrier (which means that no building paper needs to be used).

Sto Corp. has announced that Sto’s flagship liquid-applied vapor permeable air and moisture barrier, Sto Gold Coat, has been improved.

Infiltration actually poses a greater moisture threat to building envelopes than vapor diffusion

Slab-on-grade insulation can be arranged in a number of configurations, each with pros and cons

The Canal Dock Boathouse in New Haven, Conn. replaces the historic George Adee Memorial Boathouse, which was built in 1911 and served as the home of the Yale University crew teams

Freezing temperatures and precipitation can lead to problems that harm structural integrity of the building envelope and the comfort of its occupants

In the building envelope, the time soaking process of applying a separate weather and air barrier is giving way to integrated sheathing — combining the sheathing and the WRB-AB together

A city known for constant rains, dramatic shifts in climate throughout the year, and perpetual moisture, Portland provides unique challenges for any construction project
