Specifying the correct weather-resistant barrier

Weather-resistant barriers (WRBs), also known as building wraps or housewraps, are one of the best building materials for controlling water, either through blocking rain from entering the wall cavity, allowing moisture vapor to move and escape the wall cavity, or draining bulk water away from the wall assembly.

XPS delivers high R-values in below-grade applications

A new study from the Alaska University Transportation Center, University of Alaska Fairbanks, recently reported on R-values measured on insulation removed from below-grade applications in harsh climates. This supplements data from two previous similar research projects. All the three studies reported the in-service R-values per inch of extruded polystyrene...

Avoiding galvanic corrosion with dissimilar metals

When two different metals are in contact and exposed to moisture containing salts or pollutants, one of the metals can experience accelerated corrosion while the other remains protected. This type of accelerated corrosion between dissimilar metals negatively impacts the overall corrosion protection of the project and is referred to...
