Aluminum Windows & Doors
For years, architects and builders have specified aluminum windows for their overall strength and lasting value. Because of their rigidity and durability aluminum windows can be configured into a wide variety of combinations. Though not as efficient as other materials, aluminum allows huge glass expanses that not only accentuate your view but also welcome more natural light. Aluminum can easily be designed with great intricacy, which provides narrow sightlines, allowing the door or window to blend into the architecture rather than overpower it.
Aluminum windows are also popular because of their low maintenance. Aluminum won’t rust or rot so it is one of the most durable and easily maintained window and door materials. Aluminum windows and doors are offered in several maintenance free finish processes depending on manufacturer and project requirements. These include high durability baked on paint or powder coat and tough anodized finishes.
The downside of aluminum windows in the past was that they weren’t very energy efficient. Aluminum readily conducts heat and cold. Today, better quality aluminum windows, equipped with thermal frames, separate the interior and exterior surfaces of the window to improve their energy efficiency. There are two common methods: Pour/De-bridge and I-Strut. The former process involves pouring liquid polyurethane into an extrusion pocket and removing the underside once the liquid hardens. The I-Strut process involves mechanically joining a polyamide strut to two separate extrusions. Both are proven systems but struts offer more attractive extrusion designs in certain shapes.
Aluminum is naturally plentiful and perpetually surviving. Many aluminum windows and doors are made from recycled material. Moreover, aluminum rates very high in Life Cycle Assessment and leaves a small ecological footprint. All windows and doors eventually must be replaced but aluminum windows and doors last decades longer than wood and vinyl.
Aluminum is a fantastic window and door material for those interested in having narrow sightline, low maintenance, and energy efficient windows and doors.
