Fiberglass windows are created through a process called pultrusion. In this procedure, the fiberglass, in the form of roving and strand mats, is extracted through a machine that covers the fiberglass in resin.
Once coated, the fiberglass is pulled through a heated die to harden the material. The smoothed rigid pieces that emerge called lineal are cut to length, coated, and then fitted with corner blocks.
The nylon-reinforced blocks are screwed and glued together to create tight and extremely durable joints.
Pultrusion shapes glass fibers into durable pieces for window frames. Image from This Old House. One of the biggest pros of fiberglass is its ability to withstand the demands we put on our windows. The inherent properties of fiberglass plus smart engineering merge to produce top-of-the-line products that last the lifetime of your home.
Fiberglass is stronger than vinyl, as well as wood. The combination of its durability paired with its resistance to moisture guards against rotting, mold, or shrinking and swelling. In fact, The Spruce. Also, fiberglass holds up against heat that can cause vinyl and wood to flex, sag, or change dimension. This reduces the chance of leaks around the window perimeter since fiberglass and the window glass - made of the same materials - expand and contract at the same low rate. Fiberglass resists aging associated with heat and moisture.
While fiberglass is weather resistant, the material is sensitive to UV rays and can fade. One way to protect against this is to apply a long-lasting coating. Since fiberglass can undergo traditional painting, you have many options to customize coating and color to your needs. With no shrinking, warping, sagging, or corrosion, fiberglass creates a strong boundary between your home and the climate.
Fewer gaps in your windows create fewer drafts, meaning less work to keep the temperature inside of your home regulated. Glass fiber is energy efficient because it has very low thermal conductivity. By preventing hot or cold temperatures to pass through it, fiberglass effectively creates a thermal seal against the elements.
Not much, other than cleaning the glass and replacing the weatherstripping every decade or so. If the factory-applied coating gets scratched, you can touch it up with a percent acrylic paint. Most parts for a fiberglass window are fabricated by pultrusion. In this automated process, lengths of fiberglass roving and strand mat are bathed in a resin, covered with a fiberglass veil, and pulled into a heated die that hardens the resin. Separate dies are used for each window part.
The smooth, rigid lineal that emerges from the die is then typically cut to length, coated, and fitted with hidden nylon-reinforced corner blocks. When screwed and glued together, lineals and blocks form tight, clean, nearly indestructible joints.
Shown: These insert windows are installed from the inside, so the existing wood trim can remain in place. They resemble painted wood inside and out. For about 10 percent more, Pella can apply different colors on the interior and the exterior. The sills, sashes, and frames are fiberglass, but the interior surfaces are covered with either wood veneer or solid wood shown.
Compared with all-fiberglass models, the ones with solid-wood interiors command about a 15 percent premium. Only the sash of the Andersen A-series window shown is fiberglass, which moves as little as glass.
The interior parts are wood, while the exterior frame is a composite of ground wood and vinyl. Its price is comparable to that of a wood window clad in aluminum. No longer plain-Jane vinyl look-alikes, fiberglass windows have undergone big changes in key areas. Coatings Factory-applied finishes are much tougher and more UV-resistant than before, whether as a thick acrylic layer applied during the pultrusion process or as a spray-on paint or powder coating added before window assembly.
Colors Once available only in white, fiberglass windows now come in a range of colors, both on the interior and the exterior right. And if you want a different hue later on, fiberglass can be painted as easily as wood. Curves The pultrusion process makes only straight pieces, but manufacturers can now mold fiberglass into classic arch-tops left and curves.
Combinations Windows no longer have to be grouped together on-site to put together bays, bows, and other combined sets; they can now be delivered as integrated, ready-to-install units.
Energy performance By itself, fiberglass does a fairly good job of keeping out the cold. Filling the frame with foam and adding triple-pane glazing improves performance even more.
This extruded plastic makes the least expensive and most commonly installed windows, but it turns brittle with age and exposure to cold.
Joints are heat-welded together, leaving obvious bumps at corners. These high-end wood windows have an exterior layer of vinyl or metal—usually aluminum—that reduces maintenance and improves longevity. They are a close match to fiberglass in performance, but have a much higher price point. This lightweight, extruded metal is about as rigid and low-maintenance as fiberglass.
In addition to their structural virtues, fiberglass windows hold their own in terms of aesthetics and versatility. Gray, black, forest green—colored windows are more popular than ever, but dark colors are especially vulnerable to fading.
The powder-coat finish on these custom casements and double-hung windows is virtually immune to UV rays.
