Air Dome Thermal Science: Multi-Layer R-Value Insulation Envelopes & Automated Snowmelt Systems

1. Calculating Composite Thermal Resistance

Champion dual-membrane and triple-membrane envelopes incorporate an engineered air gap (300mm to 500mm) delivering a thermal resistance of R-12 to R-20, cutting indoor heating operating expenses by up to 48% compared to uninsulated structures.
