Marvins' Vinyl Window?

At a few of the home shows, we've had even builders ask about the Marvin Vinyl Window.  Guess what? Marvin does not make a vinyl window.  Vinyl is extremely soft (they make cheap blinds out of this stuff) and not suited for any building product.  It expands and contracts quite easily and can get soft and brittle, which is not something you want in a window.  The material is soft and easily bent into some nice looking round tops, but it has a very short shelf life. You'll be replacing those vinyl windows in 5 years.  Even vinyl & vinyl wood composites (fibrex) are 60% vinyl and struggle from the same durability and performance issues as vinyl.

Marvins' solution to that is their ultrex window, by Integrity.  Ultrex is pultruded fiberglass.  Fiberglass is used to make boats.  It's super strong and does not bend.  Fiberglass expands and contracts at the rate of glass (not much) and hence, a great material for building.  In fact, it might just be the perfect building material since it's super strong, 8x stronger than vinyl, basically waterproof, and requires no maintenance.  This allows Marvin to give the Integrity Ultrex window a full 20 years warranty on glass seals and 10 years on manufacturing defects.

The window on the left is made from Ultrex.  Since the tensile strength is so high (one sq inch can support 34,000 lbs) it holds it's square shape, stays true, and doesn't break down over stress.  It also reduces thickness of the frame, allowing for more daylight openings (more glass).  It also doesn't require additional sash locks like its' vinyl counterpart because it's not going to expand and contract with the weather (ultrex: 833% LESS expansion than vinyl) and lose it's shape or alignment.  By expanding and contracting at the same rate as glass, Integrity windows and doors are also much more resistant to seal failures and leaks.

The Ultrex window also has a finish 3x thicker than competitive products.  It's 100% paintable, it won't crack, dent, chip, or peel.  It comes in 6 standard colors and is the first and only AAMA verified 624-10 finish in the industry.

So, the reps tend to get a little worked up when the ultrex gets referred to as a vinyl window, because it's so far a superior product in every way.  It's stronger, more durable, better looking, has better finishes, and won't rip itself apart after 5 years of fluctuating weather patterns.  Want to learn more?  www.integritywindows.com
