Advantages of Vinyl Frames

  • Extremely durable
  • Non-corroding
  • Virtually maintenance-free
  • Exceptionally energy efficient


Vinyl frames are made primarily from polyvinyl chloride (PVC). This material has many advantages, including being virtually maintenance-free. There will be differences in the quality of one manufacturer’s vinyl compared to another. This is because a vinyl frame is made from a compound—a recipe of sorts—that dictates its performance over time. Each additive to a company’s vinyl recipe helps determine the long-term characteristics of the final product, like its weather and impact resistance. For example, titanium dioxide makes the vinyl more heat resistant. At first glance, competing windows may look the same, but there can be key differences in the vinyl recipe used and how vinyl parts are formed to make a window structurally strong and optimize insulation performance.

Generally, vinyl doors are available in white and various neutral colors. Milgard recently developed a two-coat formulation of seven premium exterior vinyl finishes available in light and dark variety, in addition to standard white and tan. New coating technology allows UV rays to pass through the color formulation and reflect off the vinyl frame. This preserves the exterior finish. Consequently, a vinyl window or patio door can look nearly new for years.
