Why Aluminum is Better Than PVC

What are the key differences between aluminum and PVC you should consider?

Aluminum, arguably, has surpassed PVC in the benefits and choices it offers.


Aluminum is 3½ times stronger than vinyl (PVC) and 43 times stronger than wood with a high strength-to-weight ratio, making it the ideal material for windows and doors. In the commercial market, aluminum has long outperformed vinyl (PVC) and wood windows and has proven to be the window and door frame material to meet the highest demand in strength, performance and longevity. This lightweight, yet extremely strong metal is used on jumbo jets and stands up to the humid, corrosive salt air by never warping, rotting or corroding.


Aluminum is a much more robust compound and with proper care will stand the test of time without compromise. Aluminum windows and doors are known to last decades longer than wood and vinyl (PVC). Aluminum resists rodents, termites and vermin.

Cleaner profile

One of the ongoing complaints with PVC, especially with more period properties, is the thickness of the profile (the frame). Because aluminum is a much stronger material, the frames can be made much thinner. This allows more light into the property and leaves the window looking cleaner with a higher ratio of glass to frame than PVC can offer.

Energy efficiency

Vinyl (PVC) and wood window frames absorb heat and cold into the frame, causing that material to fail prematurely. Aluminum is thermally stable: it does not swell and shrink when temperature or humidity levels change. To the contrary, with vinyl (PVC) and wood frames, energy is lost due to their high level of expansion and contraction.

Consistent frames all year round, from year to year

Wooden framed windows often swell, warp or rot over time. PVC can be prone to expansion and contraction with heat. But, aluminum is chemically much more robust and stable.

Where this really stands out is large panels of moving glass, such as french doors or Bi-Fold doors. The aluminum frames withstand the elements to remain consistent from year to year, whatever the weather.

Low maintenance

Aluminum offers a wide variety of beautiful finishes that require minimal maintenance. The corrosion resistant qualities of aluminum provide a low maintenance frame and is resistant to weathering under a range of harsh environmental conditions. Unlike many other materials, it will not swell, crack, split or warp over time; ensuring an extended product life.

Environmentally friendly

Aluminum is a 100% recyclable, non-toxic and a fully sustainable product. It is naturally plentiful and perpetually surviving (recyclability). Additionally, aluminum rates very high in Life Cycle Assessment and leaves a small ecological footprint. Aluminum is an abundant and sustainably harvested resource. In fact, about 8% of the earth’s crust consists of aluminum bauxite. This bountiful supply exceeds global demands and because of its recyclable nature, aluminum is the material for the next century. Lastly, 94% of the world’s supply of bauxite is mined in non-forested regions, minimizing global environmental impact.
