Architects are increasingly using perforated sheet metal to design facades. The product’s flexibility makes it a great application choice for not only the aesthetic features architects seek, but also the functional features building occupants need.
The sheets offer numerous benefits when mounted in front of glass surfaces. By varying the size of the panel, hole diameter and hole spacing, they can:
• Control sun exposure by reducing heat radiation. They also can diffuse light to eliminate glare and reduce colour fading of interior materials.
• Serve as an acoustical element to reduce indoor or outdoor noise.
• Enhance privacy so people can only see partially from the outside while the interior view outward remains nearly unobstructed.
In adverse weather conditions, perforated panels provide effective protection. Panels can diffuse strong winds to take the pressure off the building exterior. During heavy rain, windows that are behind perforated screens are largely spared while providing substantial visibility.
Designers often use perforated sheet metal on parking garage staircases or railway stations so that the areas are enclosed, but remain “airy.” With restoration projects, perforated facades or elements can be an option to stay within budget and still maintain aesthetically and functionally pleasing results.
Perforated metals are available in almost any alloy, but most commonly are made of aluminium, stainless or carbon steel. They are assembled into panels that can be formed to profile, and either attached to a building or wall mounted to a separate frame. If damaged, they can be easily replaced or duplicated. They are also resistant to dirt so they may never need cleaning, and can accommodate various coatings to emphasize colour.
Using perforated sheet metals means architects don’t have to compromise their designs to deal with functional needs. The sheet metals’ flexibility and minimum maintenance requirements make them an ideal choice to control the sun and withstand uncontrollable weather.
