WSD Skylight / Sloped Glazing Lab Test Results

Wisconsin Solar Design’s overhead systems share a common set of details and have been laboratory tested for water penetration, air infiltration, and thermal performance - U-factor and Condensation Resistance Factor (CRF).

(Please note that our thermal testing is with a representative insulated glass unit. Glass makeups vary widely, and affect the thermal performance, light transmittance, solar heat gain, appearance, etc. of a glazed structure. Please contact WSD to select or verify the glazing for your project.)
