When evaluating Bronze Reflective Glass, you must prioritize Visible Light Transmittance (VLT) and the Solar Heat Gain Coefficient (SHGC). For high-performance buildings, look for a VLT between 20% and 40% to balance natural lighting with glare reduction. Ensure the glass thickness meets your structural requirements, typically ranging from 3mm to 12mm. Additionally, verify the coating durability, specifically whether it is a 'hard coat' (pyrolytic) for better weather resistance or a 'soft coat' (sputtered) for superior thermal insulation.
