Per my roof installer, the roofing shingle I have specified (Certainteed Presidential) cannot be woven in the valleys. He says it voids the warranty. He says we have to go with metal flashing (over the usual Ice and water barrier). Is there any other product I should be looking at besides the aluminum (.032) or copper (unknown gauge) he offers? Pitches are 6 1/2 and 8. The reason I specified this shingle was the "heavy texture" appearance so I assume any similar shingle will have the same restriction.

If so, describe the recommended method. The building is 40 or so feet tall, surrounded by trees that brush the structure on 3 sides, and neighbors are within 30 feet both right and left. The building is not elevated compared to the surrounding topography. Thanks

Passivhaus question: Do hardwood floors contract and gap in winter as noticeably as they do in a conventionally-built house?

My husband and I are building a Passivhaus in Vermont and want to install hardwood floors. I'm tempted by pre-finished flooring, since we wouldn't have to go through the mess and expense of sanding and finishing on-site. But I hate the little dirt-strips that inevitably form in the micro-beveled edges.

I've been reading a lot about the importance of having a rain screen/venting behind clapboards. I seen the product Home Slicker, but also know that you can doing furring strips too. If I choose to use furring strips, would it be wise to use a product that would not rot? Such as some sort of pressure treated wood, or a plastic of some sort? If so, what would you suggest?

I have a 1950's ranch style house with what appears to be a botched insulation job in which fiberglass was blown in the walls. During some renovation work a couple years ago I discovered that the 4inch wall cavities were only filled to about 40-50%. I would like to redo the insulation with something that I know will fill in the entire wall cavities. I once considered airkrete, but have been unable to find an installer in our area (Kalamazoo, MI).

Hi, I'm considering putting an ERV in a home in the Carolinas (hot humid in summers, occasional cold in winter). This has been a great site for info, but I had a couple of questions:

I am planning a lake home in the mountains, elevation 3000 feet. I will not be living there full time and am looking for a tight envelope. I want a logical approach that will balance cost with results. Builder is on the old fashioned side. Thanks

I called on a potential client today in climate zone 5 (Northern Ohio). He built his home 20+ years ago with double studded walls, fiberglass insulation and a passive solar design. The home is approximately 1800 sq ft on two floors. The main heat source is an in-floor radiant system installed in the floor of the lower level. There is no heat on the second floor. What struck me was the beautiful simplicity of the radiant system. There are four loops of 3/8" pex installed in aluminum covered plywood panels with additional plywood and a hardwood floor on top.

Has anyone out there designed / built a thermally isolated double-stud wall AND used the airtight sheathing approach in a TWO-STORY residential project?

I'm thinking of the two-story, rectangular box as the thermal envelope. It gets wrapped on all five sides with plywood sheathing, which acts as the primary air barrier. Then it gets capped with an unoccupied, fully vented, stick built roof. Make sense?

Now, combine that concept with a curtain wall---to eliminate the thermal bridges in the framing. That's the idea anyway.
