The building digests at Building Science Corporation are collaborative efforts by some of the top building scientists working on houses today. Look at their projects and resumes and you'll see the future of low energy, durable, healthy houses without all the problems we hear of on these boards and in press articles: structural rot (I just consulted on a 9 month old $800,000 home with advanced rot last week; a 3 story wall of the house is stripped as I write), moisture/mould, EIFS failure, water behind stucco, etc.


You have to subscribe to periodicals like Fine Home Building, Energy Design Update, Journal of Light Construction, Solplan Review to keep up. Here's an article from Home Energy magazine:

RE-EXAMINING ROOF VENTILATION

The world of the roofer is changing quickly. Only a year or so ago, customers blamed the roofer for ice damming and wet-attic problems. The solution was simply to add attic ventilation, in many cases beyond building code requirements. Why? Because it was the roofer's only choice. In order to provide the homeowner with a full manufacturer's warranty, ventilation had to be installed according to the requirements of the local building code: typically 1 ft2 of ventilation for every 300 ft2 of insulated attic space, and twice that amount for low-slope roofs. Unknowingly, the roofing industry was making the wet-attic situation worse. How? They were following the correct procedure for ventilation, but solving only part of the problem instead of the whole problem. Ventilating a previously unventilated attic has the effect of making the attic colder. If nothing is done to stop warm, moist air from entering the attic space from the living space, condensation on the now-cooler surfaces is a certainty. Mold, mildew, and eventually leakage into the living space will probably follow.

Insulation contractors, armed with the same lack of information about attics as the roofers, have caused similar problems. Insulating the attic floor makes the attic colder in the same way as adding ventilation. But, if contractors don't seal as well as insulate, they don't stop warm, moist air from entering the attic and causing big problems.

Now, thanks to public debate, reeducation, and the publication of Attic Venting, Moisture and Ice Dams, a report by Canada Mortgage and Housing Corporation (CMHC), roofers know much more about what's happening, why, and what to do about it.

"Arrogence is such an ugly character flaw"

To the person who gave this comment and demerits to me this afternoon without signing your name...small, small, small.

Read some of the research and don't learn everything on the street from those who have not retrained. It's a different world out there now due to energy costs and our homes change as we insulate and tighten up.....they don't operate the way we thought they did, especially now!

I have seen this on many homes with certainteed shingles. There was a recall on there shingles for pre-mature failure. I know because not only do I have them but so does my parents house. Both have pre-mature failure.

Here is a 6 year old home with the same shingles.

Sorry the picture sucks but the roof has horizontal cracking on almost every shingle. Full ridge vents with adequate soffit vents and insulation.

Turn off your rating system and stop those silly buggers from having the privilege of making anonymous derogatory remarks. They don't like it when someone has an idea that runs contrary to the grain.

Cheers,

From the above article: Reexaming Roof Ventilation

"For kneewalls, the top plates and joist cavities under the half-story are sealed with foam, and the vertical wall is insulated using mineral fiber batts."

An alternative to this is at US DOE's Energy Efficiency and Renewable Energy website:
http://www.eere.energy.gov/buildings...pdfs/26447.pdf

The last section titled KNEEWALLS shows a better way of doing this area. Started doing the kneewalls this way in 1983.

Cheers,

If that happened Those with PEE brains would have no fun .
I do feel anonymous post's are wrong .
If I give a person ( and I have ) a red or green I always give my name
I try to always be fair and If I make a mistake I will Apologize
Sorry but I refuse to let others make some decisions for me .
The humorous part of this from every thing I have read Brian is correct so Pee brain has not been reading and increasing their education.

They come and they go some see my posts and do not Read to learn.
Some show how jealous they are and then they go into another industry as they just do not seem to survive and Criticism upsets them .
Sleep hope you sleep well tonight I know I will and you intimidation will not effect me .

Barry, I had the same problem about a month ago... I couldn't get into the site but everyone else I asked could. I tried the other day and got in just fine. Have never figured out what happened, as I had no trouble getting into any other sites.

Roy,

Someone is obviously very bored. I guess you'll have to simply ignore this damn idiot (retard).

[Marcel R. Cyr]

Good morning David;

I have a few choice words in French that would offer that descriptsion also.
But, I can't translate. ha. ha.

[Barry Adair]

what some don't get is every time one of us gets a red for disapproval another 10 come along and give us a green for approval.

overall ratings increase so their act backfires.

Cookie,

If your gonna be pea let it be green, from me
