In addition to linear vents, engineers may often design fabric duct with precise surface permeability via a standalone distribution method or in combination with any vent combinations. This also promotes more uniform airflow, temperatures, and efficiency.
There is no doubt inflation, supply chain disruptions, and other residual effects of the pandemic continue to affect Canadian construction projects and delay their completion. However, there might be a silver lining to this dark cloud. Once projects are ready for HVAC completion, choosing fast-installing ventilation materials can help speed up projects. Further, the effects of the pandemic might also prompt the construction industry to look elsewhere for more suitable, alternative building materials, which will also offer energy efficiency, durable esthetics, and high performance for building owners now and in the future. Both metal and fabric duct have a place in the construction industry. Architects, specifiers and design/build contractors should examine every project scope for the best choice.
