Why INFINITY from MARVIN?
MADE FROM A PATENTED MATERIAL
CALLED ULTREX FIBERGLASS
It’s 8x stronger than vinyl, 3.5x stronger than wood/vinyl composites (Fibrex), and one square inch can support 34,000 pounds!
ULTREX FRAMES CAN TAKE THE HEAT
The temperature threshold of Ultrex is 350 degrees. Frames made of vinyl (PVC plastic) are prone to warping from temperatures that are common in the Arizona summers and don’t conduct heat like aluminum frames.
PATENTED, MECHANICALLY BONDED INLINE ACRYLIC FINISH
The acrylic coating is up to 3x thicker than competitive finishes, providing superior resistance to discoloring,
Ultrex is manufactured with the base material of silica sand — an abundant natural resource and NON-TOXIC… unlike vinyl that needs massive amounts of petroleum and other harmful chemicals. If you’re concerned about your carbon footprint, INFINITY from MARVIN is the way to go!
AS STRONG AS LOW-CARBON STEEL
This strength keeps windows square, level, plumb and true. That means no warping, cracking, or premature failure of the frame. It’s a fact… Arizona weather is brutal on windows. The constant heat expands lesser frames by causing warping and sagging. Ultrex is so strong…we guarantee it, for life.
