Some of the greatest benefits of ventilated tensile membrane facades are their ability to block UV rays and reduce the overall impact of solar heat gain for large-scale facilities while adding to the aesthetic appeal of your building.
With advances in the energy efficiency of windows, there are options for reducing solar heat gain somewhat by replacing the facility’s windows, but for high-rise corporate offices or large manufacturing plants, this can seem like an unnecessary and inefficient cost. Also, once the window replacement process was complete, the building will still rely on unsightly and expensive curtains and blinds to block the glare.
Tensile membrane facades do the work for you by reducing solar heat gain and blocking troublesome glare. As seen in the illustration, facades are installed parallel to the building's envelope with some ventilation room between the building and the mesh wrap. The tensioned PVC or PTFE-Coated Fiberglass membrane reflects some of the UV rays, absorbs and releases some, and allows a small amount to pass through as natural lighting.
While the exact numbers vary based upon the specific fabric being used with a tensile membrane facade, it's common to see 40% of the solar radiation reflected, 32% absorbed by the membrane and released in the ventilation shaft, and only 28% being transmitted into the building. This means the interior of the building enjoys diffused natural light without the impact damaging UV rays.
