Investigation revealed 3 problems: 1) no soffit vent; 2) insulation extending beyond the end of plastic rafter vents closing off the air channel up to the ridge vent; 3) no blocking above the wall to seal up the fiberglass. I've corrected the first two and caulked the ridge on the inside, but am unable to fix the blocking. The odor persists and I fear the fiberglass is contaminated with mold that the revived air flow won't be able to dissipate. Would pulling out the fiberglass (through the soffit to avoid major deconstruction) and filling the bays with foam work?

I am planning a 30'x22' farm workshop in Eastern Ontario, Canada. I want to end up with a level floor suitable for woodworking machines (table and bandsaws, planer, jointer etc) , Floor will be on grade, location is on a small rise and I will make sure there is good drainage away from building. I will place 2" of SM insulation under floor. I will most likely frame double stud walls and insulate with 6" to 7" of Roxul.

Hi. I haven't been here for a while because I thought I had found the solution to my crawlspace problem but alas I haven't. I had been dehumidifying the crawlspace at our beach house with a high capacity Santa Fe dehumidifier which unfortunately got destroyed when the crawlspace was flooded during Superstorm Sandy. Rather that buy a new one, I had a vapor barrier installed, replaced the open vents with insulated smart vents and had the underfloor of the house covered in 2-3" of closed cell spray foam.

I'm looking for a detail for integrating an insect screen with vertical corrugated metal siding that is meant to function as rainscreen.

Are the typical metal J-trims and flashings enough to keep bugs out of the corrugated flutes or is there a better way?

I'm looking for an effective membrane and/or application to air seal a home with walls made up entirely of exposed CMU.

I'm working on the mechanical systems design and spec for the home and advising the builder to lower the infiltration so we can keep latent loads to a minimum. I am not interested in R-Value.

The 5,000 s.f. home is located on a very small private island just north of Exuma, Bahamas, and it is surrounded by ocean. The interior and exterior finish of the home is exposed CMU.

I am building a home that will use a combination of a mini-split and passive solar in the Pacific Northwest. For thermal mass it has a concrete slab floor with insulation underneath.

My question is about flooring. I was planning on an engineered wood floor but my builder pointed out that this would prevent the sun from heating the slab. He suggests a stained concrete floor or tile. I really do not like either of these options.

How bad is a wood floor? Would a Terrazzo type floor using recycled glass such as Enviroglass be a good option?

I'm building a house where the exterior walls have been sheathed with a bitumen treated structural fiberboard. I have two questions:

1. Should I tape the seams of the sheathing on the exterior side of the wall? If so, with what?

2. What is the best WRB for this type of wall assembly... building paper or Tyvek/Typar etc.?

Thanks.

We are working very hard to get green cabinets from a custom woodworker. Air quality is our primary concern. We are confused about what type of finish should go on these cabinets--the cabinet fronts will be solid wood (walnut and oak).
