Presenters Peter Yost and Mike Guertin were inundated with questions during their 12/18/2009 webinar Got Mold? - Energy Efficiency and Moisture Management.

This forum is a space for questions that Peter and Mike were unable to get to during the 60-minute presentation.

What's a good low-VOC shingle that lasts, say, 40 years?

I'm thinking 5 sun tunnels and two skylights would be easier to install on a shingled roof, also the dormer maybe.

When will Part 2 of the webinar "From Designed to Built: Delivering Your Green Home" be available?

From Designed to Built: Delivering Your Green Home: I read the short transcript of this webinar, since I am currently working with an architect and a "volunteer" builder to develop the plans for a green home of ~ 3400 SF.

The information on your website was excellent and very pertinent to what I am presently doing....is it possible to revisit the actual webinar broadcast which I think was aired in late October and.....when is part 2 scheduled to air?
Thanks, Bob Weber

Is the new Foam Sealant product by Owens Corning effective as an air sealant and safe for human health?

I am working on a project for a client who has a home on the bay just north of Galveston Island,on the mainland .
This is an existing 4 year old house. As it is positioned it receives on the South face of the house a wind from the South which is super saturated with moisture.

In the attic,we have had a lot of problems with this moisture laden air infiltrating through the most minimal of openings,cracks and even between where the sheetrock and the side of the top plate touch.There is also a negitive pressure existing within the envelope of the house.

Moisture condensation

I recently installed dense-pack cellulose in a 1929 home. After the install, the amount of moisture condensing on the windows increased significantly. Why would this happen. The relative humidity in the home should be the exact same before and after. The windows are original with fully closed storms.

Is it possible to eliminate condensation with insulation?

I was wondering if it was possible to insulate so much that the dew point actually occurs in the insulation? Also if this was to occur would it eliminate condensation or would it still occur within the insulation? I can see this as maybe being a possibility in a ceiling but would it be possible in a wall?

How can we prevent condensation, and eventually ice, to form on the clothes dryer exhaust duct?

I live in a newly renovated and insulated house in Montreal, Quebec, Canada, where the minimum temperature range between - 20 to - 25 F. My clothes dryer exhaust duct is about 1 feet long and connect the clothes dryer directly outside. When not in use, condensation forms on the duct, drips on the hard wood floor, and eventually, ice forms on the duct. All of this is quite logical, but I have never heard of such a problem before. The house temperature is about 70 F. There is not a lot of air circulation between the exterior wall and the dryer so I've installed a small fan in front of it.

What are the best sealers for concrete block walls and concrete slab floors, when applied from the inside.

As noted in the webinar, stopping moisture at the outside face of an assembly is always best, but for older (1950's & 60's era) concrete block walls and concrete slab floors below grade, what type of sealer products or other techniques work best to try to prevent moisture penetration, and subsequent musty smells? Thank you.

Photo of moisture on concrete floor in slide show

what’s the origin of the moisture in the concrete floor and mold behind the trim photo? Was it when the floor was cleaned? Or a plumbing break? Or when the concrete was drying during install?

Once mold moisture is gone and growth is stopped, must the stain be removed?

When remodeling a story and half, mold was found in a section that was unheated but will now be in the heating envelope. Will this staining need to be bleached or just left as is?

Thank You,
Dan

Designing to dry

In middle Tennessee, I always see deck bands bolted over cladding directly to the house band. There is never any flashing and this crushes the drainage plane behind the cladding. The result is both deck and band joist rotting. I'm amazed at the lack of designing to dry.
