14 Replies
Have anyone performed a blower door test on a new home that has a multi bi-fold door installed on an exterior wall? (As in NanaWall, Lanai or Sierra Pacific bi-folds). Is there any performance…Continue

Armando Cobo replied to Greg La Vardera's discussion New Construction: Easing Builders into High Performance Construction"Greg,
There is so much that I disagree with your AF blog, that it would take another thread to get into. I believe your view of AF is too simplistic, but it also takes good detailing and practice. I've designed a lot of homes with AF for…"
Armando Cobo replied to Greg La Vardera's discussion New Construction: Easing Builders into High Performance Construction"Interesting framing method and I appreciate the effort to show the videos, however, I have differences of opinion with Mr. La Vardera on a few points:
1. Advanced Framing is not just a top plate and in-line framing only issues, but also designing…"
Armando Cobo commented on Macie Melendez's blog post The Google Earth of IR Images—Q&A With Storm Duncan"Interesting technology development and it could be a great improvement for our business, but the skeptic in me asks if they have validated or compare their results of their program with “old fashion” independent energy audits. Just…"
Armando Cobo replied to Jennifer Rupnow's discussion Crawlspace Vapor Barrier: Install Correction and Future Guidance in the group Best Practices (Residential)"John, Drying is the whole idea... with a closed cell it'll never get a chance to dry out and it'll rot; or maybe we need to agree to disagree on the building science of it."
Armando Cobo replied to Jennifer Rupnow's discussion Crawlspace Vapor Barrier: Install Correction and Future Guidance in the group Best Practices (Residential)"On the contrary, if there is any wicking through the concrete or any moisture leaks on the rim joist, the open cell will allow any wood and the wall assembly to dry."
Armando Cobo replied to Jennifer Rupnow's discussion Crawlspace Vapor Barrier: Install Correction and Future Guidance in the group Best Practices (Residential)"Sorry, I should have said: open cell foam on the rim of the floor joist."
Armando Cobo replied to Jennifer Rupnow's discussion Crawlspace Vapor Barrier: Install Correction and Future Guidance in the group Best Practices (Residential)"My experience with sealed, conditioned crawl spaces, you need to have a 20 mil poly-reinforced liner, with 0 perm rating, sealed with approved tape or mastic on the joints and to the wall. Good liners have an antimicrobial additive that will not…"
Armando Cobo replied to Armando Cobo's discussion Blower door testing on multi bi-folds"You are so right David. It would be nice if their testing is done under the same realistic conditions as their products are tested in real world... that maybe too much to ask. I'll keep waiting on a rater's test one of these days."
David Meiland replied to Armando Cobo's discussion Blower door testing on multi bi-folds"I assume they're referring to an ASTM E283 test, although I could be completely wrong... and as far as I know, that test uses a number of different test pressures and conditions, it's not a simple -50pa blower door test. BUT... if that…"
Armando Cobo replied to Armando Cobo's discussion Blower door testing on multi bi-folds"Here is the only reply I've had from any manufacturer:
A Regional Manager for Sierra Pacific Windows said: “We do not have the report yet, but here is the data from the test lab, for our bi-fold doors. This was forwarded to me by one of…"
Bruce Navin replied to Armando Cobo's discussion Blower door testing on multi bi-folds"Yes, I and unless the door came with an integral frame, I don't see how they would be able to give a reliable result simply due to installation variables.

Armando Cobo replied to Armando Cobo's discussion Blower door testing on multi bi-folds"One of the problems we get with all manufacturer's data is that it's usually performed in control environments,,, and it would be nice to know how these doors do in real world. I've taken tours of a half a dozen window companies, but…"
David Meiland replied to Armando Cobo's discussion Blower door testing on multi bi-folds"It'd be nice if the manufacturers could give you some air-infiltration test data to use. There's a spot on the NFRC sticker for air leakage, but apparently very few manufacturers do the testing on their products.
I've tested some…"
Armando Cobo replied to Armando Cobo's discussion Blower door testing on multi bi-folds"Thanks Bruce for the suggestions. I've looked at their websites but no information on BDT and leackage. However, no details show your sugestions, I'll wait a little longer on the manufacturers and see what they have to say."
