Best loose fill insulation for concrete block?
2013年10月4日 · That is good news, as dealing with any loose fill is awkward (especially if there is wind). I had planned on both filling the cores with loose fill and 4" of foam on the interior of the block frost wall, with 4" under the slab on grade and at the slab edge. Interesting data on moisture and air movement in block walls, so fill the last block we ...
Fixing Attics With Vermiculite Insulation - GreenBuildingAdvisor
2015年4月17日 · Here in Montana, where there is lots of Zonolite in attics, the Weatherization crews routinely test for aesbestos. Cost is about $45 as I recall. An inspector suits up, carefully takes 3 samples from different parts of the attic, mixes them into one and sends the sample in. Turn around is very quick.

Air-Sealing Concrete Blocks - GreenBuildingAdvisor
2021年2月28日 · If you really want to "seal" the block on the interior side first, you could use block fill paint. This is the type of paint typically used on block walls commercially, which will seal the little voids and provide a good finish. It's not typically used as a "sealer", but it will work for this purpose in a low-demand application like this.
Perlite insulation? - GreenBuildingAdvisor
2017年3月27日 · Mineral wool is a popular insulation recommendation, but it seems expensive and has limited supplier options. I came across some info on perlite (and even vermiculite and lightweight expanded clay aggregate [LECA]) as a potential insulation material.

The problem with using such a large unit of concrete is the weight of the block. I was thinking of using a high density Polyisocyanurate or Polyiso foam block in the center of the form to take some weight out of the Hearth.
Recognizing unsafe vermiculite removal - GreenBuildingAdvisor
2017年10月19日 · At first sight, the insulation in that attic look to be loose fill of some sort, on top of a layer of black plastic. However, the attic portion above the garage is not treated the same way, and it looks to us like unvacuumed remains of some grainy material, possibly mixed with some nasty rodent feces.
