Dryer vent cap
I am currently researching into dryer vent caps that provide an air-tight seal. I am aware of the Ecovent, the Seiho RCC-S with back-draft damper, and the Heartland products. I came across another product manufactured by a Canadian company, Dundas-Jafine Co., their ProShield(TM) telescopic dryer vent hood. I like this idea of having the air flow push out the vent and at the end having it pulled back to close, and the whole assembly is rather unobtrusive and not sticking out from the wall. You can view this vent hood at
The Heartland seems to generally get favorable reviews. I don’t find much information out there about the ProShield. Does anybody have any input or experience with the ProShield, or with the Seiho product for that matter? How air-tight are they in practice? We are not talking about a passive house application but the home is being built to the Canadian R-2000 standard on Vancouver Island, BC, so insulative value and air-tightness is an important consideration. Many thanks.
