I am a little (a lot) late to this conversation, but I think the only wood-burning appliances should be direct vent masonry ovens which burn at such high temperatures that they burn off all the nasty particulates and gases.  And even then, they should only be used in an emergency situation, where power is out for an extended period of time.

Wood burning in my area (near Fresno, CA) destroyed my health and made me chemically hypersensitive.  Not just residential wood burning, but also the nasty, dirty practice of agricultural waste burning.

Combustion appliances are really...

Am hearing about this new technology and seeing positive reviews online but have also being told that they're not appropriate for larger, older homes. What are the challenges and limitations of heating an older, larger home with a new heatpump system?

Hi Patsy,

This listing is just for BlueskinVP, not Air Bloc (a fluid-applied product), which we do not list. On the landing page you have to click on the sheet-applied product tab, but it is not exactly intuitive, so I have changed the url so it directs people to the specific BlueskinVP 160. Thanks for bringing this to our attention.

Note that when you search the Henry's website for Blueskin, you're directed to a page that has 3 products with Air bloc in the name. The Air Bloc 33 has phthalates.

I am looking for an expert opinion regarding open-cell water-based foam. It is clearly less expensive, and admittedly a bit less effective, than closed-cell foam.  Is it worth considering, especially for attic insulation?  AND, is it better to insulate the attic floor or the attic rafters. Any advice would be greatly appreciated!

Great Content,  I was finding difference between adhesives and sealants and got only one that that sealants typically have lower strength and higher elongation than do adhesives, Is there any other difference that will help me, as I am using  Acrylic Adhesive for some Industrial use is their any other which is best in case of fixture time and power?

Cork seems like a really great substitute for plastic foam-board insulation for sheathing. While expensive and only available from the Mediterranean Region now, perhaps the trees could be grown in more different areas of the world. This type of insulation is yet another way to sequester "tree concentrated" carbon into structures.

We are using this technology on a large 150,000sf new corporate headquarters in Princeton NJ with a large amount of exterior glass curtain wall on the South and West facades and expecting to achieve significant energy savings, glare control, and improved comfort as a result, according to our energy model. We have been working closely with Aplen on the project and found them to be a great source of knowledge and extremely cooperative.

Kathleen, I apologize if this was confusing. We use CSI Masterformat numbering to organize the product listings in GreenSpec. I'm not totally sure I understand your comment, so if you can clarify how this is confusing, I'd appreciate it.

Alex,

Check out http://www.phoenixwindow.net/ for a double-glazed storm with heat mirror coatings; or closer to home, try Harvey storms, which have low-e options.

My question should have been, "Do the bubble wrap foil products have adequate air space built-in to effectively act as a radiant barrier?"

posted by tristan on Mar 4, 2013

David, a  radiant barrier needs an air space in front of it to affect radiation of heat. If it is just sandwiched under concrete then the aluminium foil will be a very good thermal conductor, i.e., a poor insulator, while the radiant barrier will have no beneficial effect. There is (probably) a time and a place for radiant barriers, as long as we understand their benefit and don't over-rate it.

How about foil coated bubble wrap under radiant heated slabs?  Does any of it really work?

if you are going to list the sci spec number you should let people know that it is not the spec.

FYI

This product is not sold in the US.  It is not manufactured with US fittings.  I'm going to purchase one and work with my plumber to see if we can adapt it, but for now, this isn't going to work for most US projects...

70.00 dollars per gallon is a concern.  

But using the 80/20 rule the labor cost is the main issue.

Subflor and Dricore
posted by Brent Ehrlich on Jun 28, 2012

Hi John,

MSDSs are notoriously confusing. The formaldehyde levels on DriCore's MSDS look like they are the regulatory limits for ACGIH and OSHA and not the tested values of this product.

The reason might be as follows. The core of Dricore is OSB, and OSB typically uses a phenol formaldehyde (PF) resin. OSB is exempt from...
