"No way would I start from the bottom. It is so much easier to re-due the roof then remove drywall and trim and whatever else is on the ceiling. Other thing not considered is the control of debris, fiberglass, drywall dust, possible mold exposure,…"

Hello all Home Pro's! I am wondering what is the best designed HRV or ERV you are using on your projects. My personal favorite is the Venmar Guardian Plus Hepa HRV.…Continue

Kevin Wood replied to George Whiting's discussion Retrofit insulation on the roof over cathedral ceilingKevin Wood replied to Dwayne M Petko's discussion condensation in attic"OK next is the insulation has become saturated somewhere and you will have to find the area. I would say it might be time to get a scan of the ceiling for cold spots and to check the area with a non invasive moisture meter. I have found situations…"
Kevin Wood replied to Dwayne M Petko's discussion condensation in attic"Your problem is in design according to what I see in your first picture. The covered entrance section needs to be completely sealed and vented from the main attic from the inside. The moisture collected below the walk in area or patio is trapped at…"
Kevin Wood replied to George Whiting's discussion Retrofit insulation on the roof over cathedral ceiling"Sorry I can't access where it is but your best bet is to remove the plywood and add Closed cell SPF leave a gap below the new applied plywood sheathing and ventilate from the soffit to the ridge vent. this will prevent the ice dams.

Kevin Wood replied to Kevin Wood's discussion HRV or ERV"Paul the design of the one I put on provides more air to pressurize the house just right. Not sure what the figures would show but even when a HRV or ERV is balanced at times the home is not according to the wind and stack effect.
You are correct…"
Paul Raymer replied to Kevin Wood's discussion HRV or ERV"Seems like a number of discussions going in a single thread. In an increasing number of homes, mechanical ventilation is necessary. Relying on natural leakage to provide adequate pollution dilution in the house generally means that on…"
Kevin Wood replied to Silas Inman's discussion Best Energy Myths"I also agree because of its ability to float in the air much more easily than other Insulations of today. Because it is a fiber or rod shaped it is hard for the microphage to absorb around it. This is very similar to the problem with asbestos.

Bob Blanchette replied to Kevin Wood's discussion HRV or ERV"Going from a "rock catcher" to a 4" thick Merv 8 filter will make a HUGE difference in IAQ for minimal cost."
Bradford E. White replied to Kevin Wood's discussion HRV or ERV"I agree with Kevin regarding the need for mechanical ventilation vs. relying on passive, uncontrolled ventilation though places you do not ask about in polite company.
That aside, Venmar, Lifebreath, Fantech are, depending on model, fairly…"
Bob Blanchette replied to Kevin Wood's discussion HRV or ERV"Code is very lax in Oklahoma. It isn't uncommon to find straight electric resistance heat as a primary heat source for a home. Yes it's expensive to run, but it's cheap for builders to install. Most parts of the country cringe at the…"
Kevin Wood replied to Kevin Wood's discussion HRV or ERV"Bob we have the strictest requirements just put in place in Ontario in the new Ontario Building Code 2006 and it applies to all homes from 2012 and up. This is also going to be put in place in all Commercial buildings soon after 2013 You are correct…"
Kevin Wood commented on Peter Troast's blog post Have a Listen: "The Blower Door Man is Coming to Town" from the Energy Circle Lounge"He's checking the list, He's checking it twice, he wants to find out which house is loose or tight, The blower door man is coming to town."
Bob Blanchette replied to Kevin Wood's discussion HRV or ERV"Few residential customers care enough to pay for ventilation technology to be installed. IAQ would be much improved by air-sealing and ductwork repair, yet few are willing to pay for it. Even if it were to become code tomorrow it would take years…"
Kevin Wood replied to Kevin Wood's discussion HRV or ERV"It is code where I am from and let me tell you if a house is leaky then you are breathing the crap that comes in from the exterior walls. Not healthy. Granted I do understand in US why this might be a problem to digest as many days are very hot and…"
