Rainscreens as external cladding have been around for decades, but advancements in technology have made them increasingly popular. This is due to two key factors—their ability to deliver optimal performance metrics, and the flexibility they provide when it comes to design options.
Concrete is susceptible to fluid and vapour infiltration and migration. Crystalline waterproofing technology improves the durability of the concrete by filling and plugging pores, capillaries, and micro-cracks with a non-soluble, highly resistant crystalline formation.
Water-resistive barriers (WRBs) play a vital role in the performance of a wall system. Unfortunately, barriers can be undermined even before they clad the walls due to ultraviolet (UV) exposure. Understanding and minimizing the impact of UV on WRB is critical to ensuring the integrity of the wall assembly and building performance for years.
Roof enclosures have the largest litigation potential in the construction industry due to complexities in design, application, and environmental exposure. A self-drying roof enclosure would minimize the litigation potential and provide additional benefits, such as increased roof resiliency, reduced financial burden, and minimal impact on the environment.
Zero-lot-line-construction typically requires the application of blindside waterproofing to various types of shoring conditions. Some waterproofing consultants and professionals feel redundant waterproofing is the most effective method in these conditions.
The Vancouver Island Chapter is having a luncheon meeting on understanding and preventing floorcovering failure. The event will take place on Thursday, April 18, from 11:30 a.m. to 1:15 p.m. at Fireside Grill in Victoria, B.C.
The Toronto Chapter is holding a dinner meeting to discuss mass timber structures. The event will take place on Tuesday, April 2, at the Toronto Skating Curling and Cricket Club from 5:15 p.m. Participants must sign-up before Friday, March 29.
In cold climates, condensation-resistance performance is expected for standard curtain wall systems. However, occupancy factors, unconventional building geometry, design details, and the design of heating systems and interior finishes may result in the reduction of condensation resistance, as demonstrated by a case study of a 12-storey commercial building in Montréal.
The proper selection and placement of vapour-impermeable materials within wall assemblies is fundamental to their durability in both cold and warm climates. Failure to correctly account for the impacts of vapour diffusion can lead to damage and premature failure of wall assemblies.
The trend towards higher performing buildings and envelope systems requires a re-doubling of effort towards achieving durable, constructible, and maintainable transition details. There are many ways for these details to fail. Fortunately, there are also many opportunities throughout the design and construction process to focus on getting them right.
