Concrete is poured into the panels, creating shallow overall slab depths that increase floor-to-ceiling heights, thus maximizing open spaces below.Įmbodied carbons associated with the COMSLAB panels are reduced because significantly lower material is used versus traditional cast-in-place slabs (CIP) – roughly 60 per cent less rebar and 30 per cent less concrete – not to mention the environmental advantages of cold-formed steel itself.Īccording to Bailey, “Cold-formed steel framing meets multiple green building program objectives based on attributes including high recycled content and high reuse potential, good thermal performance, low building site waste, and the fact that it is an inert material that doesn’t release harmful chemicals and resists the growth of mould, mildew and other bacteria.”Ĭhevalier has given the label “EkkoHaüs” to his combined use of ICF, concrete and COMSLAB floor panels. These long cold-formed steel panels act as a permanent concrete form offering spans of over 30 feet. When properly assembled, ICF requires less labour for both interior and exterior finishing, since insulation and vapour barriers are integral to the foam blocks themselves.Īlso of note is the use of COMSLAB steel decking, fabricated by Bailey Metal Products (BMP) headquartered in Concord, Ont. In terms of concrete use, it is estimated using ICF reduces the amount of concrete required by a traditional poured wall by 10 per cent. The result is a strong, well-insulated, waterproof shell. Rebar and concrete are inserted inside the hollow blocks. Nudura ICF blocks are large, hollow Lego-like foam pieces that link together to form foundation and upper walls. President Marc-Antoine Chevalier promises resilient structures that will resist water infiltration, bad weather and earthquakes. In the Vieux- Bordeaux area of Montréal, Brossard contractor Chevalier Séguin is using concrete in combination with both Nudura ICF and cold-formed steel floor slab profiles in the construction of three row townhouses called Maisons Klome. These innovations reduce the amount of concrete without any loss of structural integrity while reducing the CO 2 associated with traditional construction methodologies. Two recent announcements have highlighted the combined use of concrete with other building materials to resolve challenges in both permanent and temporary housing.
