A stunningly comfortable first impression

Clark University, located in Worcester, MA, is a widely respected research institution, particularly for its excellent science program. To reflect the cutting-edge research that is happening inside its buildings every day, the university is committed to investing in its campus exteriors, in hopes of attracting top students and faculty. That’s why, after three decades, it […]

Large Building Airtightness Testing and the Selection of Appropriate Air Barrier Strategies

An airtight building enclosure is an important part of a modern building. Good airtightness can increase energy efficiency, improve durability, and allow greater control over occupant comfort and indoor air quality. Airtightness is achieved with an effective air barrier system that is carefully designed and detailed and then built and commissioned in the field. An […]

Protecting One of Toronto’s Architectural Gems

The Integral House is arguably one of Toronto’s most unusual and spectacular residences. Its name reflects the summa symbol (∫) used to represent the integral in calculus; though it is known more simply to many as the Toronto Mansion. The 17,000-sq.-ft. Rosedale home was designed and built in 2009 for esteemed mathematician and calculus textbook author Dr. James […]

Easier, Faster and More Accurate Wall Designs

Wall designs are one of the most time consuming projects for an architect.  As you design buildings that are energy-efficient and compliant with code changes, the wall details become more detail-oriented and evermore critical to the performance of the building. Cosella-Dörken, in collaboration with Roxul, has generated BIM files for wall sections, including air and water-resistive barrier details. […]

Common Problems that Reduce the Effectiveness of Your House Wrap

High-quality house wrap is most often made of spun, high-density polyethylene fibers. It is a vapor-permeable material designed to simultaneously block the passage of liquid. Properly installed, it’s a WRB with the ability to resist moisture while allowing humidity to escape from exterior wall cavities, which is of particular importance in humid climates. However, unforeseen […]

Premium Metal Cladding Systems and Roofing Benefits

The aesthetically pleasing nature of zinc and copper cladding attracts architects looking to unite durability, sustainability and creative expression. High-end metal cladding provides a dramatic and eye-catching contrast to other materials, including brick, glass, wood and concrete. High End Metal Cladding and Its Benefits Both metals are popular for use in metal cladding because they […]

Rainscreens Create Structure and Separation to Protect Against Moisture

Without proper ventilation and drainage, moisture can accumulate between the water-resistive barrier and siding of a building. A rainscreen separates the cladding from the building, allowing drainage and moisture evaporation. Ventilated rainscreens are a support system in the building envelope that separates the cladding from the building, allowing for proper ventilation and drainage. It does […]
