After system design and material selection, Benson manufactures a Performance Mock-Up (PMU) assembling a representative sample of the building’s exterior façade. During this phase, Benson procures new die shapes, gaskets, silicone, architect approved glass, and paint colors to then fabricate, assemble and glaze curtain wall units to represent what will be produced once project manufacturing begins. Typically 2-1/2 stories high and 25 – 50’ wide, the PMU is installed at an independent testing lab similar to the way they will be installed on-site. This specimen is then put through a battery of tests to verify the curtainwall system performance specifications for air and water pressures, structural and thermal characteristics, window washing and re-glazing methodology.
Benson also prepares mock-ups for NFRC and acoustic testing when required. Our rigorous testing procedures validate our engineering and assure the project curtainwall meets the highest standards.
