VINYL VS FIBERGLASS WINDOWS

ULTREX® FIBERGLASS

ULTREX® fiberglass for unmatched 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.

MATERIALS MATTER

Vinyl frames expand and contract

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 VS FIBERGLASS

Comparing Ultrex Fiberglass Window Frames to Vinyl Window Frames. Sliding Doors and French 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 making vinyl windows difficult to open and close and affecting they're all-around performance.

EXPANSION AND CONTRACTION

The glass expands at 4.6 the vinyl expands at a 30 which is 652% more than the glass. So as the different materials expand 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.

Let's now compare what happens with Ultrex frames. Ultex 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 sleek beautiful design that provides more viewable glass that is as strong as steel and built for life.

ULTREX STAYS TRUE

Ultrex fiberglass Frames 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 fiberglass 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.

Vinyl expands at a 30. This is what happens to window frames with heat and cold temperature changes. When temperatures heat up outside the glass and vinyl both heat up and expand.

Stands up to the pressure

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.

ULTREX FIBERGLASS STRONG AS STEEL

Ultrex resists sticking, swelling, and warping so Infinity windows and doors will continue to easily open and close. The fact is the engineering specification proves that a vinyl window expands and contract 800% more than our Ultrex frames. Ultrex frames are even 4 times stronger than aluminum-framed windows and have the tensile strength of steel.

What does all this mean to you as a homeowner? ULTREX® HAS VERY LOW THERMAL EXPANSION RATES. 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 MORE FRAME LESS VIEWABLE GLASS


Ultrex vs. Vinyl Windows

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.

Ultrex vs. Wood

Windows Wood 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 MORE VIEWABLE GLASS THIN SLEEK FRAME

More view for your money

Ultrex® fiberglass not only provides unmatched durability compared to other window replacement materials — 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 of it in Infinity window frames. That means you get more daylight and greater views outside coming through your window, without bulky materials obstructing your view. And we pay 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 Fiberglass frames are as strong as steel so they are thinner sleeker and more elegant which results in more viewable glass with a sleek frame.

Beauty that lasts

Infinity from Marvin is the only company that applies this proprietary, high-performance, co-extruded acrylic finishing process which is unlike anything else in the industry. Our 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.

A Finnish That Resists Fading

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.
