I've seen references to this place, but has anyone actually ordered materials from them?  Just curious if the savings live up to the claims on their site.

I received some quotes for reclaimed glass-fiber faced polyiso from Green Insulation Group, Boston, MA (although their ad said Worster, MA?).  In an email, he said: 

"I have 4” x 4 x 8 , or 2” x 4 x 8.   

4” is $26 per sheet, 2” is $14 per sheet" 

I am not at the point yet for ordering materials.  Dana1 has commented that he purchased reclaimed glass-fiber faced polyiso from Insulation Depot or one of those outfits in Massachusetts, and used it in his basement.  I think he paid $20 for 3" x 4' x 8', which would be right in line with the quotation given above.  You might PM him if you need more details on the quality of the materials.    
 

I did actually get a response this morning. I had filled out the online quote request but wasn't sure how quickly they'd respond. I had a follow up question that was immediately responded to as well, so that was a good first step.

My initial request was for approx 3200 sq ft of 2" xps (100 4x8 sheets). Materials & delivery was $1800. He said that they have a hard time keeping xps in stock, & poly iso board would be a little cheaper - about $200 less for the lot. At that rate, it looks like the net cost would be around $16/sheet. Local building supply house wants about $27/sheet. So far so good..

Wow, that price looks very good if it includes delivery. How far away are you from their place? I did not ask about delivery, but assumed that was the price to pick it up at their place.

Lee -

According to their website, they're located in Framingham, MA. I live in Green Bay, WI, so I'm guessing freight a decent "chunk' of that amount. He did specifically say that the price included delivery. I was pleasantly surprised, it seems like an awfully good deal.

I've bought from them & been very satisfied. He told me they have insulation in other locations across the country, so they probably aren't shipping it from MA

Insulation Depot ships from its reclamation jobs or from assorted warehouses, the nearest to me being Williamsport, Md. Check Craigslist first for better priced (and closer) reclaimed foam. I paid $5/ea for 2"x2x8 XPS.

My boards were stored in a leaky barn, and, yes, XPS will dry out although it took six months.

If you can't wait for the foam to dry out, wet xps weighs more, obviously, it has a solider THONK when you smack it, and it breaks more readily than dry foam. Otherwise, my foam was super dirty. Every fourth or fifth one had cosmetic dents. About five percent was wet.

I usually back the truck up to their Waverly Street Framingham address for small lots.

My friend doing a deep energy retrofit on a 3-family had The Insulation Depot deliver a gia-normous stack of 3.5" fiber-faced iso to the job site in Worcester. (About a 60 minute round trip from the job site.) I don't recall the exact price he got, but it was well under half that of virgin stock- (and cheaper than the $20/sheet I paid for 3"x 4'x'8' goods from a different local trader when I did my basement) and the goods were in BEAUTIFUL shape, with very few dinged corners or facer punctures of any size. Shipping was similar to delivery charges for virgin-stock from a local distributor in this case (not surprising, given the proximity.)

IIRC they have a large warehouse in W-VA too.

The WVA location is probably Williamsport, which is across the Potomac from WVA.

Ordered 1100 sq ft of iso from them 4/27, received a call from Dave (reclaimed insulation guy) on 4/30 to make payment. He had originally quoted me 400 for the 1100 ft2 but told me some of it might be in pretty bad shape so he'd give me what he had left at this particular warehouse (lincoln, RI (very conveniently 5 min away from me)) for the same price. I ended up with 6 pallets stacked 8' tall with 4' x 3' x 1.5" tar paper faced 2 sides iso. All pieces have holes where the screws were pulled, about 80% are missing 1 corner, 10% have all 4 corners and are in perfect shape, 10% are pretty busted up and will be used to fill the missing corners. The only thing i'm worried about is that it wont perform as well as fiber-faced when I install it against my foundation. Any help on this would be appreciated... Mat

In 1984 the only published research to date on underground applications of rigid foam insulation was a study by Dow Chemical, in which samples of insulation were buried for extended periods and later unearthed. In those tests, foil-faced polyisocyanurate foam insulating board did not fare so well, absorbing on average 5 percent water by volume and losing 40 percent of its R-value. any exposed or broken edges will allow it to take on water into the cells

Sorry I missed an important detail... It'll be on the inside of the foundation.

On the interior face of a reasonably well drained foundation that doesn't have major efflorescence showing on the interior it'll be fine- it isn't remotely the same as burying it on the exterior without capillary breaks or any direction in which to dry.

If you leave an space (or insert an inch of EPS or something) between the edge of the iso and the slab and it can't wick & accumulate moisture. The asphalt-paper facers are a strong class-II vapor retarder, but can still pass some moisture (unlike foil facers.) Repairing holes, broken corners, & sealing seams with 1-part expanding foam doesn't hurt either, but wouldn't be an absolute necessity (if your foundation is that wet you need to deal with the bulk moisture issues.) The vapor pressure from non-saturated 50-55F foundation isn't very high, and without a strong moisture wicking path between the concrete and the iso won't be taking it on any faster than it can deliver it to the interior. If you have a lot of broken corners to fix/fill-in it might be worth buying a Froth-Pak or similar 2-part foam kit. (The 12-board-foot kits run $40 at the big blue box store, and beats a case of 16 oz cans of 1-part foam.) The spray foam has about the same R/inch as the iso, and is non-wicking and vapor-retardent.

If the foundation has significant dampness/efflorescence it may be wise to stop a foot or so above the slab to allow more drying capacity toward the interior to protect the foundation sill from water wicking up from the footing. Taking care of exterior moisture by grading the slope away from the foundation, adding/repairing gutters, installing surface drains/French drains is important too. Using vapor permeable masonry sealer on the exposed above-grade exterior limits wicking of drip-edge splash back and into the foundation without eliminating it's drying capacity for the ground water helps too. Any corners where roof valleys may drain and saturate the soil want special treatment to move that water elsewhere too.

[edited to add]

If you don't have big overhangs or the gutters tend to drip close to the foundation, it may be worth treating the exterior of the foundation with a buried moisture diverter:  http://www.greenbuildingadvisor.com...81.png

Don't buy from Insulation Depot, you could get better material from the dump. I had 160 sheets of 2" ISO delivered
and it was a wreck. Broken corners, squashed sheets that fell apart when picked up. Many rocks and gravel pieces stuck all over. And those were the good sheets.

I called David Volpe in Framingham after sending MANY emails...he called me a liar and hung up. Framingham is a ghetto full of thieves.

STAY AWAY FROM INSULATION DEPOT

READ THEIR WEBSITE...THEY GET YOUR MONEY FIRST THEN THEY DELIVER GARBAGE!!!!!!

You got better stuff than me. Only 10% busted up? My order was 25% busted up.

I assumed that we'd need the 30% extra I bought from Insulation Depot, figuring at the price I was paying it was still a great deal. I was wrong; we used almost all of the material and even with the little cutting and patching we did and the cans of foam we used to fill the holes and voids, we saved a bundle. It's advertised as "used" and "salvage"; anyone expecting "seconds" with minor imperfections is kidding themselves. I'm sure there are bad batches; obviously BuilderDave got one of them. We looked at the sheets before we bought them, he apparently didn't. At these prices and with that material you are taking a chance; we did well, he didn't. I'd buy from there again, but I'd again, look at what we are buying.

With any reclaimed building materials, "YMMV".

When dealing with the local foam reclaimers (including Insulation Depot) the lot-pricing reflected the condition. I don't have a huge amount of experience with any one vendor, but the condition of has never been mis-represented, by Insulation Depot or any other.

bump . anyone have recent purchases and experiences with insulationdepot... particularly XPS? obviously its reclaimed and not new.... local reuse center has XPS that's normally in great condition, just not large batches or whole sheets.
