Melanie, good catch. Looks like this product no longer has Greenguard certification. I've updated the listing.

Hello, I am having some difficulty locating documentation on the 700 Series GREENGUARD certification via the Owens Corning website. Is there any documentation to back up their claim? Thanks! Melanie Loftus

I recently had a Misubishi mini split system installed in our home. We installed (3) indoor units...(1) on main floor, (1) in upstairs master bedroom and (1) in finished basement. The house has 1700 square ft. I have the upstairs, master bedroom unit set at 64 degrees and woke up this morning to a room temperature of 45 degrees! The outside temperature was 8 degrees. We have had to turn off the unit on the main floor and the basement level in order to conserve electricity. Our readings were up to 45 kw per day expenditure with all three units running at a set temperature of 59 degrees!...

Hello, I am a sculptor and have been using AAC as my medium for a number of years and my supplier just dried up! I teach classes in it and use daily and need a supplier fast. Can anyone offer me any help?

thanks,

Jon, as we wrote in our more detailed EBN review, the binder is formaldehyde. Testing shows that it emits from the product levels less than 0.0135 parts per million (ppm). Average background levels are 0.02 ppm. So in theory someone could react to this, but we are not emphasizing it in our writeup since the data shows it is a very minor point, especially when this insulation is placed...

I was surprised that the review of this product didn't mention the urea-extended phenol formaldehyde binder. According to a EBN a Article "Formaldehyde is a known carcinogen, but according to the industry, almost all of the formaldehyde in mineral wool insulation is eliminated in the production process through a chemical reaction and high heat." Roxul claims low emission levels but sensitive individuals could have a reaction and would be cautioned not...

I agree that the fossil fuels are limited. However, the properties of our top soil is limited also. I live in iowa, after seeing $8.00 + corn the farmers have ripped out every tree and weed to plant another row of crop ground. As our population increases so does the demand for energy and resources. It seems like we are substituting materials from underground to our top soil. As we attempt to curb the use of fossil fuels for (air quality)making products and energy, we are removing the qualities of our ground (top soil) that ultimately feeds us. It also increases the speed of natural...

I did ultimately install a Geospring in the basement of my house (prettygoodlakehouse.com). I can't hear it at all in the living space but the basement ceiling is quite heavily insulated. For me - since I was building basically a new house - the cost of the wiring was more than offset by not needing to do the gas plumbing and the exhaust gas ducting.

Our Geospring water heater is located in our basement, separated from the living space only by an uninsulated floor. If the door to the basement is closed we can't really hear the water heater (about the same decibel level as a refrigerator) from our living space upstairs. I would think in a garage if there's an insulated ceiling above there would be no noise migration at all.

Noise was a factor we considered, though. We installed it in a separate room in the basement that we could insulate if we need to. We also chose the quietest HPWH that was available when I was researching...

i've been looking at these water heat pumps and the hidden costs and considerations are installation requirements (30A circuit), location of demand points, noise (huge factor because many garages in san diego are located below a bedroom), and the initial costs. I had wanted to build a house with PV cells + water heat pumps. Whether it's one large one or several small ones around the house closer to faucets and showers. Looking at it from several angles, I can't seem to justify it even though it's what I want to do because I love the coolness factor. It's not really as straightforward...

You simplified PV to much. Inverters and panels can stop working so there is maintenance. Also you lose a lot of those electrons moving though inverters and from roof or barn into the house, especially on smaller wires. The true measure of a PV should be how much energy is available at a point of use in vs. generated by the panels?

A well designed Solar thermal hot water heating system a little maintenance. Glycol protects the system from freezing and steam-back (a larger expansion tank) protects the system from blowouts during a power outage . If the internet is available, a...

Hi Jill,

You raise a good question, but rest assured that Huber is not adding free formaldehyde. I spoke with the company and they are simply accounting for the free formaldehyde that occurs naturally in wood. They should probably make that clearer, though.

Thanks, Brent

According to the MSDS (http://www.huberwood.com/assets/user/library/AdvanTech_MSDS_2013.pdf), AdvanTech contains "free formaldehyde." Adding formaldehyde would seem to negate the benefits of using MDI and PF instead of UF, no? Or is it really low-emitting, and what does this mean? Thanks for your great...
