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 fiberglass just keeps going. Window Replacement is made for Fiberglass because it's strong and it lasts.
Ask yourself why don't they make boats out of vinyl? Because a boat made out of vinyl would be a very bad idea. Between the beating and pounding of the boat against the water and the heat of the sun, the vinyl would break apart on the first trip to Catalina.
Vinyl is a soft material and can warp and shift under everyday conditions — potentially making vinyl windows difficult to open and close and affecting their all-around performance. 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 their all-around performance.
VINYL VS FIBERGLASS WINDOWS EXPANSION AND CONTRACTION COMPARISON
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, you can see the different rate in which each material expands and contracts.
VINYL VS FIBERGLASS REPLACEMENT WINDOWS
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. Ultrex resists sticking, swelling, and warping so Infinity windows and doors will continue to easily open and close.
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.
ULTREX STAYS TRUE
Ultrex fiberglass 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 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.
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 FRAMES 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. This not only makes Infinity from Marvin the best fiberglass windows it makes them the most energy-efficient fiberglass windows made.
What does all this mean to you as a homeowner? ULTREX® HAS VERY LOW THERMAL EXPANSION RATES. This means that Marvin fiberglass 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.
The most energy-efficient windows and the greenest windows in the world. Infinity from Marvin Ultrex Fiberglass windows and frames are made completely from sand which is the most abundant natural resource in the world. No bi-products no waste just sand.
