Depending on whether the concrete block walls will be covered or if the top of the wall is exposed can really change the way they are insulated. The option for insulating concrete block walls include spray foam insulation, injection foam insulation, polystyrene beads, foam boards, and mineral loose-fill.Click to see full answer. Similarly, it is asked, what is the R value of a cinder block wall?Concrete block makes a cost-effective and structurally sound wall, but it has little thermal resistance. Depending on the density of the blocks, an 8-inch thick block wall without any other type of insulation has a thermal resistance value between R-1.9 and R-2.5.Beside above, should concrete blocks be filled? The concrete blocks that are used to build block foundations are hollow. After the concrete blocks are laid, the voids can be filled with a cement-based mortar or poured concrete that contains small pea gravel. If the builder does this, the filled concrete block walls become nearly identical to poured concrete walls. Hereof, how well do cinder blocks insulate? Just plain old cinderblock walls with nothing inside them are probably so low on the R-value scale as to have no insulating effect at all other than as a wind block. CMU block has good thermal mass. Once its warm inside the building,itshould stay warm,and stay cool once cooled.What type of insulation do you use for cinder block walls?Depending on whether the concrete block walls will be covered or if the top of the wall is exposed can really change the way they are insulated. The option for insulating concrete block walls include spray foam insulation, injection foam insulation, polystyrene beads, foam boards, and mineral loose-fill.
