Thermal Insulation Performance Measurement for Architectural Glass & Reflective Thermal Insulation Coatings for Buildings

Architectural glass needs to meet transmittance and thermal insulation requirements, while building reflective thermal insulation coatings are required to have qualified thermal insulation performance. The SPM30250 UV-VIS-NIR spectrophotometer performs full-spectrum scanning within 300–2500 nm, outputting parameters including solar reflectance, visible reflectance, near-infrared reflectance, solar transmittance, visible transmittance, shading coefficient and haze of materials. It complies with standards such as GB 50411-2019 and GB/T 2680-2021.
