Builderscrete offers pavers, retaining wall blocks, landscape and building blocks, and brick veneer made from cellulose, portland cement, sand, binders, and other ingredients. The cellulose is sawdust from local sawmills, and although Builderscrete uses some portland cement, the company claims it is much less than standard concrete masonry units (CMUs). Builderscrete products do not require any firing or steam curing and are a third the weight of standard CMUs. They also provide an R-valueMeasure of resistance to heat flow; the higher the R-value, the lower the heat loss. The inverse of U-factor. of 4.74 for a 7.67"-thick block, significantly better than the R-value of conventional blocks (R-1.11 for an 8" block). Builderscrete also offers a Super Insulator Block that contains a core of high-density EPSExpanded polystyrene. Type of rigid foam insulation that, unlike extruded polystyrene (XPS), does not contain ozone-depleting HCFCs. EPS frequently has a high recycled content. Its vapor permeability is higher and its R-value lower than XPS insulation. EPS insulation is classified by type: Type I is lowest in density and strength and Type X is highest. foam and no thermal bridgingHeat flow that occurs across more conductive components in an otherwise well-insulated material, resulting in disproportionately significant heat loss. For example, steel studs in an insulated wall dramatically reduce the overall energy performance of the wall, because of thermal bridging through the steel. . It is available in thickness from 4" to 12" and has an R-value up to 23, depending on thickness of the block and foam core. Builderscrete products will hold a nail or screw without drilling pilot holes
