Where To Buy Foamglas |TOP|

The biggest obstacle, as they point out, is that it is a manufactured product. All the fill and aggregate that goes into one of my builds comes from pits within ten miles - and even then the trucking is a large part of the expense. Getting this stuff from where it's made to where it's needed is a problem.

Also, it's a lot like foamglas, and they have a page that describes adding carbon powder added before it goes in the furnace. Foamglas does clearly state that no HFCs, CFCs, or HCFCs are used on another page.

This seems like the same concept, but broken into bits as it comes off the line. I can see how there are some applications where the crushed format is useful, but I would think that boards would be preferable for insulation applications, having higher R-value per inch and not needing compaction to get there. I hope that some of the makers of this stuff can tweak their lines and sell boards as well.

Trevor, I'm not sure where you got "less than 1%" for compaction. I'm going by this caption from the article: "When compacted to about two-thirds of its original loose depth, the insulating value of foam glass aggregate reaches about R-1.7 per inch, according to its Vermont importer. (Image credit: Glavel)" Insulation companies often exaggerate test data, so I wouldn't be surprised if R-1.7/in is on the upper end of what's possible. In the article they state a range (I'm assuming loose-filled, though they don't say) for 12" Aeroaggregate, which translates to R-1.0 to R-1.3/in.

Yes, you have to work hard to compact fiberglass enough to round that corner. Enough that it's not a practical problem for fiberglass. ASHRAE Fundamentals has a plot showing that it is around 3 lbs/cu ft. where it turns the corner. This stuff in in the 10 to 20 lbs/cu ft range. So at face value, it might already be in the density range where more density makes for worse performance.

Reply to Charlie, #26--yes, Fig. 1 on p. 26.2 in my 2017 copy shows anywhere from 2.0 to 4.0 pcf as the turning point, depending on material type. Figure 2 shows that as fibrous insulation fibers get larger, the optimum density gets higher; I'm not sure how that relates to foamglass since both the "solid" aggregate and the voids between aggregates are insulative.

Foamglas products are an ideal product from a sustainable standpoint. Other insulation products need to be replaced due to settling or sagging or losing effectiveness. Replacing cellular glass is not necessary since it is stable and rigid enough to keep its structural integrity. Energy savings and insulation effectiveness will be constant for a longer time with foamglas than other insulation products. Shutdowns can be expensive, and this high quality insulation aims to reduce the impact of shutdowns across the life of your operation.

The price of foam glass depends on its application and requirement of end-use, for instance, the price varies according to different of thickness, length, and width of foam glass. Such as foam glass price with (65 Thickness x 100Width x 450Length (mm)) was around USD 159.04 slap whereas (140 Thickness x 215 Width x 450Length (mm)) was around USD 133 per slap. Thus, the foam glass price varies from a range of USD 181.38 to USD 272.07 cubic meter depending on its sizes. 041b061a72
