Government institutions are increasingly recognizing the role the Passive House standard can play in effectively reducing greenhouse gas (GHG) emissions and are beginning to introduce it into their requirements and codes for all types of new buildings. British Columbia is leading the way.
Experiments conducted by RDH Building Science, National Research Council Canada (NRC), and a manufacturer of insulation materials have confirmed the presence of gaps between boards of insulation will cause a reduction in its R-value.
Ontario-based Nudura Corporation, a manufacturer and distributor of insulated concrete forms (ICF) in North America, has been brought by Dryvit Systems, a manufacturer of exterior insulation and finish systems (EIFS).
When selecting air barrier products to employ in building designs, architects have a broad range of choices. Spray foam insulation products are often selected because they can provide superior performance and also contribute to greater energy and operating cost savings in buildings.
The Centre for Construction and Engineering Technologies at George Brown College, Toronto, in co-operation with a manufacturer is studying the performance of continuous air barrier, vapour retarder, and fibreglass insulation products.
A recent workshop on fire properties of materials concluded cross-laminated timber (CLT) and insulation applied to the exteriors of high-rise buildings are among the materials most in need of urgent research and development.
Insulating concrete forms (ICFs) are a method of construction using components manufactured from expanded polystyrene (EPS). The forms are stacked, steel-reinforced, and then filled with concrete. When completed, ICF walls provide a solid monolithic structure.
Water is the most significant factor in the premature deterioration of our buildings. Excessive moisture accumulation on porous materials can lead to water penetration, freeze-thaw damage, efflorescence, cracking, and façade soiling.
