ULTREX finish is the highest rated in the industry the first and the only one to have achieved AAMA 624 verification. Our finish performs so well we offer ULTREX also carries the best energy efficiency ratings in the replacement window industry.
Instead of bulky wide and unappealing frames with an unfinished corner, we created thin elegant frames that are built for life. If you compare our beautiful finish to all other window frames you can see the difference in the manufacturing quality, the gorgeous design, the smoothly welded corners, and the ultimate sleek finish. You can choose from 7 interior and exterior color options and 8 wood grain options.
Want long-term color retention in a variety of styles? Ultrex® uses an acrylic finish that is paintable, fade-resistant and virtually maintenance-free. With a finish that’s 3 times thicker than competitive options, Ultrex® resists chipping, denting or peeling.
There are two other companies that started producing fiberglass windows in the last few years and there is a huge difference when you compare the quality and performance. Infinity from Marvin has been producing ULTREX fiberglass for 25 years and is the only company that that has the patented pultruded co-extruded acrylic finishing. During the manufacturing process Infinity allies 3 layers of their patented special acrylic finish which is unlike anything else in the industry. The propriety thick, even acrylic Finish is free of pinholes, striations, and imperfections and will resist scratches, fading, and chalking to retain its original beauty. This propriety acrylic Finnish is applied both to the outside and inside frames for added protection from the harsh sun and weather for decades to come.

Let’s now compare what happens with ULTREX® frames. ULTREX® expands and contracts almost the same as the glass. When the 4.6 glass heats up it expands toward the ULTREX® frame 4.0 which is strong as steel and unmovable. The result is a frame as strong as steel with a thin elegant design that provides more viewable glass. This means that our windows and doors stay tight and true even after extreme temperature swings. ULTREX® expands at virtually the same rate as glass and maintains a tight seal, so it’s resistant to leaks, seal failures, and stress cracks that can compromise energy efficiency and long-term performance.
Vinyl has a 30.0 expansion when it heats up so it expands 8 times more the glass is surrounds, pulling away from the glass and causing ceil failure. Vinyl can crack, peel, chip and fade under the heat and cold changes daily. When a vinyl window is installed contractors must leave up to a 1/4 inch gap between the frame and a vinyl window because a vinyl window frame must have the room to expand and contract under the heat and cold if they did not leave that gap of air the vinyl window would warp and even explode when it expands into the frame. Plastic bends, warps, cracks and fades it is a fact.
Vinyl can warp and shift under everyday conditions — potentially making vinyl windows difficult to open and close and affecting their all-around performance. Ultrex® resists sticking, swelling, and warping so Infinity windows and doors will continue to easily open and close.
Vinyl frames must be manufactured thicker wider, bulkier in order to support the heavyweight of the glass. Because vinyl needs thicker wider frames in order to support the heavy dual-pane glass the result is more frame and less viewable glass.
Wooden windows offer classic beauty that, depending on the environment can require maintenance and care. Infinity windows capture the beautiful details and profiles of wood — without the maintenance.
ULTREX® not only provides unmatched durability compared to other window replacement materials, but it also makes a lasting impression both inside and out. From narrower profiles that deliver bigger views and more daylight to color options that resist fading, Ultrex® simply delivers.
Because ULTREX® is so strong, we actually use less material in Infinity window frames. That means you get more daylight, more view of the outside, more glass, without bulky materials obstructing your view. We pay extra attention to the details that matter — like our clean, non-welded, corners that let you make the most of your beautiful view.
ULTREX® exclusive patented frames are as strong as steel so they are thinner sleeker and more elegant which results in more viewable glass with a sleeker frame.
UlLTREX® windows are as strong as steel, our frames are manufactured thinner, trimer, and sleeker because they are strong. Thinner, sleeker frames result in more viewable glass.
ULTREX® expands at a 4.0 virtually the same rate as glass, at a 4.6 so our windows stay tight and true. This makes Infinity windows resistant to leaks, seal failures, and stress cracks that can compromise energy efficiency and long-term performance.
Compared to other materials, Ultrex® is the strongest window framing material in the replacement industry. This means Ultrex® resists bending and flexing — that’s confidence Fibrex® and vinyl simply can’t match.
The Material You Choose for your windows and doors will have impacts far into the future.
Your window and door choice affects your energy efficiency, the security of your home, even the quality of your life. It’s not a decision that should be made lightly. Our advice? Study the facts and choose wisely
Vinyl has a high rate of expansion and contraction compared to glass. This can lead to seal failures and stress cracks. Some vinyl/wood composites are 60% vinyl infused with wood fibers and struggle from similar performance issues as their vinyl counterparts.
Infinity windows and doors are built with Ultrex®, a highly durable, state-of-the-art, pultruded material with acrylic capping. This pioneering technology benefits from 20 years of proven performance in the field
Comparing ULTREX® Window Frames to Vinyl Window Frames. Sliding Doors, French doors and Bi-Fold Doors require large amounts of heavy glass, your frames must stay true and be strong enough to support all that heavy glass. Southern California temperatures can start off at 40 degrees and reach up to 110 degrees on the same day.
Vinyl frames expand and contract bend and warp with the changing heat and cold temperatures of everyday conditions, potentially causing the vinyl to chip, peel, bend and fade making vinyl windows difficult to open and close and affecting they’re all-around performance.
The glass expands at a rate of 4.6 the vinyl frames expand at a rate of 30 which is 652% more than the glass. So as the different materials expand at different rates the vinyl expands 652% more than the glass, the frames pull away from the glass which eventually will cause ceil failure in your windows, the argon gas leaks out and your windows are no longer energy efficient. Remember this happens every day they expand in the heat and contract in the cold with the daily temperature changes. In this engineer specification sheet above, you can see the different rates in which each material expands and contracts. ULTREX® Fiberglass outperforms all other materials hands down.
Vinyl frames expand and contract. Vinyl is a soft material subject to chipping, peeling, cracking, fading, and can warp and shift under everyday conditions — potentially making vinyl windows difficult to open and close and affecting their all-around performance.
We created Ultrex® with one goal in mind: develop the most durable window material in the industry. It’s not only 8 times stronger than vinyl — it resists expanding and contracting in any climate. So you get a tight, snug fit that will last.
Vinyl Window Frames Expand and Contract: Vinyl materials are great for many different products, like patio chairs and lawn furniture. However what happens to plastic furniture when you leave it in the sun for a few years? It starts chalking and deteriorates, it warps and falls apart in just a few years. There is a reason boats are made from fiberglass because they take the beating of the ocean waves, the heat of the sun, and the cold of the water, and ULTREX® just keeps going. Window Replacement is made for Fiberglass because it’s strong and it lasts.
Compare Fibrex® material is made from 60% vinyl and 40% wood products mixed together to attempt to make a stronger vinyl window. It is the best vinyl window you will find it’s 3 times stronger than most other vinyl windows, however, it is still a vinyl window and is subject to the same problems that vinyl windows have. They don’t have a protective acrylic coating like Infinity from Marvin’s ULTREX® frames so the colors are subject to fading in the sun over time and it can be subject to the same problems as other vinyl windows. Compare the performance of the Fibrex material to
