The fenestration industry in Canada has seen a rebranding in recent years with the result being the renaming of the national and regional associations to include fenestration in their respective association names. At the national level, the Canadian Window and Door Association are now named Fenestration Canada, and at the regional level, the Window & Door Manufacturers of BC (WDMA-BC) are now named the Fenestration Association of BC. The name change for WDMA-BC is a result of a merger between the WDMA-BC with the Glazing Contractors Association of B.C. By having these two trade associations working together as one entity, the continuing challenges associated with meeting regulatory requirements and keeping up with evolving technical innovations can now be dealt with more effectively.
At the conference held in Burnaby on October 23rd, three topics that directly pertained to the wood window and door industry were discussed. The first topic covered Proposed Fenestration Changes likely to be in the new 2012 BC Building Code. Although the code has not been published as of yet, Murray Frank of Constructive Home Solutions presented information based on the information available to date.
The second topic dealt with Best Practice for Window and Door Replacement – Wood Frame Buildings, a topic intended for contractors and consultants. A guide has been compiled by RDH Building Engineering Ltd and it provides a methodology to assess the existing conditions of a fenestration replacement project that includes replacement product and installation considerations and installation details, followed by a consumer checklist. The guide will be made available early in January 2013. Follow-on guides covering Maintenance Matters for Consumers will also appear in the months following and will likely be available through provincial and federal government agencies.
The third topic dealt with Glazing Issues for Windows, by demonstrating that the addition of a durable “e” coating or Mid e coating to the room-side glass surface (i.e. the #4 surface) of a two panel window glazing system, can improve the products’ thermal performance or U value. Mid e is a more durable glazing coating than the regular low e coating. Application of a mid e coating provides the glazing greater ability to withstand potential damaging action on the exposed #4 surface. This technique of gaining more thermal performance from an existing two pane window system can delay the eventuality of having to convert to a three pane window system to achieve the mandated thermal performance requirements. Shifting to triple pane glazing systems will require considerable retooling of the wood window and door profiles to accommodate the wider glazing unit thicknesses, plus additional testing will also be required.
