Webpolystyrene foam insulation, prescribes a short-term (6 months) R-value for XPS insulation, despite the new FTC R-value Rule requirement. In contrast, the corresponding Canadian material specification, CAN/ ULC S701.1, requires a minimum predicted R-value at 5 years of age, typically referred to as the Long-Term Thermal Resistance (LTTR). WebPerlite offers thermal insulation and stable U-value performance that lasts for the entire design life of the building. Perlite lightweight concrete is ultra-lightweight, which allows for the reduction of structural building elements during the design/construction phase. Perlite is non-combustible and fire-resistant.
