Marvin composite windows material is unlike any other.
Some companies use materials like sawdust and vinyl to produce a composite material with fundamentally different properties and performance values.
But Ultrex is different. Its material makeup contains a high density of woven fibers bound by a thermally set resin, making it more resistant to pressure and temperature than vinyl-based composites.
Ultrex’s enhanced performance over time and exceptional durability make it an ideal choice for customers seeking a strong, versatile, and long-lasting window or door.
