After system design and material selection, MiTek manufactures a Performance Mock-Up (PMU) assembling a representative sample of the building’s exterior facade. During this phase, MiTek 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 curtain wall system performance specifications for air and water pressures, structural and thermal characteristics, window washing and re-glazing methodology.
MiTek also prepares mock-ups for NFRC and acoustic testing when required. Our rigorous testing procedures validate our engineering and assure the project curtain wall meets the highest standards.
