The Trend to BRONZE for Thermally-Broken Windows

You may have recently noticed the slow change in the hue of metal doors, windows, and equipment in hospitals and medical facilities across the world. The ever-increasing list of metal options is giving way to a variety of unique architectural finishes. The hard glare of stainless steel is slowly being replaced by warm and comforting tones of BRONZE, BRASS, and COPPER.

According to a study done by the United States Environmental Protection Agency (EPA), certain brass and bronze material containing at least 60% copper are naturally antimicrobial. Copper has the ability to kill up to 99.9% of microorganisms in a matter of one to two hours, whereas these types of microorganisms can live for weeks on stainless steel surfaces.

These red hue metals are also just as durable as stainless steel and become completely immune to outside elements once oxidized. They embody a luxurious and rare aesthetic alongside protection and practicality for any home.

Portella is the only manufacturer of thermal steel windows to include a thermally-bonded zinc galvanizing corrosion resistant coating. With the new trend to red hue metals such as bronze, brass, and copper, we are now introducing our Bronze metal option to our current top-of-the-line thermally-broken windows.
