Fiberglass is a great frame material for windows and is known for its strength, durability and performance. As a building material, fiberglass is nothing new. It’s been around for a long time- floating boats and adding strength to ladders for many years. But, until recently, the complex profiles required for window designs have been impossible to attain with fiberglass. Innovative window manufacturers like Milgard® have solved these challenges and today you can buy fiberglass windows and patio doors designed to maintain their beauty in every season, in any climate.
Fiberglass windows look like wood. They can be painted and stained, and come in a wide array of colors but best of all fiberglass is impervious to water, cold, heat, insects, salt air and ultraviolet rays. Unlike wood, fiberglass frames won’t crack from dryness, swell, peel or warp. What’s more, because fiberglass frames are basically glass fibers and resin, the frames expand and contract very little and at about the same rate as glass. This puts less stress on the seals and increases their durability and effectiveness.
Fiberglass windows are a popular choice because, just like a wood window frame, you can paint Them! But there is one more big difference—you don’t need to treat fiberglass frames with toxic preservatives to prevent rot and decay, and they won’t deteriorate if the paint gets scraped off or damaged.
Fiberglass frames are popular because a wood veneer can be added to the interior as well. This gives you the best of both worlds: the durability of fiberglass frames on the exterior and the warmth and beauty of wood interiors.
Fiberglass windows are usually a little more expensive than windows and doors made out of vinyl or aluminum but fiberglass windows and patio doors can be a much better value over time. Their attractiveness adds much greater value to your home than other other window materials. Equally important, their durability and long life enable them to hold their value for years and years.
