Open-cell foam is porous, allowing water vapor and liquid water to penetrate the insulation. Closed-cell foam is non-porous, and not moisture-penetrable, thereby effectively forming a semi-permeable vapor barrier. (N.B., vapor barriers are usually required by the Building Codes, regardless of the type of insulation used.
In the United States, the International Building Code and ASTM International define Exterior Insulation and Finish System (EIFS) as a non-load-bearing exterior wall cladding system that consists of an insulation board attached either adhesively, mechanically, or both, to the substrate; an integrally reinforced base coat; and a textured protective finish coat.
Roll cages help to stiffen the chassis, which is desirable in racing applications. Racing cages are typically either bolt-in or welded-in, with the former being more straightforward and cheaper to fit while the latter is stronger and more substantial. [2] A roll bar is a single bar behind the driver that provides moderate rollover protection.
Some tractor operators have raised concerns about using ROPS in low-clearance environments, such as in orchards and buildings.
