For the past few years, a seminar on new and innovative green building products has been a staple at Construct Canada.
This year was no exception, as Windmill Development Group and BuildGreen Solutions partner Rodney Wilts provided an update on the latest technologies, materials and systems — his sixth such presentation at the annual exposition.
“The green products marketplace has had a radical evolution over the past six years,” he said in an interview later.
“We now have so many more green building products.
“Overall, selection has grown, quality of products has grown and efficiency has improved.”
In his presentation, Wilts reviewed a slew of “great, green products” in the energy, health, and materials sectors. He also touched on future trends.
“Some of these products are just coming on the market,” he said.
In the energy sector, products that were reviewed include: the SolTech integrated solar thermal system, a new way of integrating solar energy into a building; and coloured solar PV panels, which Wilts described as a “modest” innovation.
“Previously, if you wanted to do solar, it came in one colour — black.”
In the health sector, products include halogen-free polyiso roofing insulation; “tunable” lighting which blends the efficacy of LEDs with the ability to have full control over the colour and intensity of indoor lighting; and “air purifying” hardwood flooring.
“We just stumbled upon this product recently,” Wilts said in reference to the flooring product.
“This is something we are starting to investigate in our office.”
In the materials realm, one of the innovative products that made the cut was Fireclay CRT tiles, manufactured in California from 100 per cent recycled e-waste — such as old televisions and computer monitors.
CRT was first introduced in the early 1900s as a way to transmit images. But demand has been rapidly declining since the introduction of LCD displays.
“This company is turning these items into quite good-looking tiles, thus avoiding their disposal in landfill sites,” Wilts said.
Other innovative products include:
— Panels designed to control sound reflection that are manufactured using recycled PET plastic bottles, eco-friendly dyes and no added adhesives;
— Enviroshake roofing products composed of recycled tire rubber, cellulosic fibres and post-industrial recycled plastics;
— Certified “green” gravel. This product is expected to be on the market next year.
— Cross-laminated timber (CLT). Wilts said the “fully structural” engineered wood panels can enable much taller wood buildings to be constructed.
