VIDEO: Canada should embrace rainscreen cladding systems
Canada has been too slow to embrace rainscreen cladding systems, despite the advantages they offer in terms of better performance, low-cost maintenance and longer-lasting structures, says a distributor of architectural building products.
“These things are proven, they’re just not being used, and that’s kind of a shame on us,” Blair Davies, vice-president and general manager of Mississauga, Ont.-based Engineered Assemblies Inc., told the Building Envelope Solutions forum conference in Toronto recently.
A rainscreen facade is an open-joint cladding system that uses a double-wall: an outer layer that keeps out rain and an inner layer that provides insulation and prevents energy loss.
The system allows natural ventilation into the cavity between the panel and the insulation, helping to provide drainage for rain and condensation.
Davies noted that these wall systems have the same performance as the three-foot thick walls of buildings built in the 1800s.
“Unless you’re going to build the Notre Dame Cathedral, why not design a wall system that works – that’s thin and light and economical?” he said.
Another advantage of rainscreen systems versus conventional walls is that they provide the option of simply changing out the panels, Davies noted.
“These systems last forever, and 20 years from now when you want to change the colour of the building, take the panels off, put some new ones on.”
“Think about all the ugly architecture that was beautiful back in its day and we can’t do anything about it now,” he added.
“(With) this kind of architecture, you could actually change it a few years from now if you wanted to.”
