Introducing an Innovative, Ultra-Durable Fiberglass Siding from Marvin

Put away your paint brushes and scrapers.  With new APEX™ Ultrex® siding from Marvin, you can have the beautiful look of wood with the maintenance-free advantages of fiberglass siding.   The siding is manufactured with Ultrex pultruded fiberglass, a material patented by Marvin.  For nearly 20 years Ultrex® has proven to be a great choice for  low-maintenance, high-performance window and door products.  And now Marvin has extended this exciting technology to siding as well.   Its proven ultra-durability makes it a perfect choice for siding. 

Designed by Marvin with four elements as priority – strength, beauty, heritage, and performance – APEX™ Ultrex® siding products are now available to Minneapolis/St. Paul area homeowners.  Window Outfitters, Inc., one of Minnesota’s leading home remodeling contractors, is proud to be among a select group of Minnesota companies selected by Marvin to carry and install this innovative siding system. 

What makes Ultrex®  different from other siding products on the market today, and what are its advantages to you as a homeowner?  Ultrex siding is:

  • Able to withstand a wide range of extreme temperatures, from 350?° to -30°
  • Superior resistance to impact
  • Incredibly stable – resists warping, twisting, and buckling
  • Virtuallly impervious to moisture, meaning it won’t rot or suffer deterioration from dampness
  • Pest resistant – rodents don’t like the taste, and insects can’t eat it
  • Compared to other siding materials, it has a low expansion/contraction rate
  • Finish, which is four times thicker than factory-applied paint, and is resistant to chipping, dents, and splintering
  • Great color retention –   resists chalking, fading, and streaking

APEX™ Ultrex® siding and trim accessory products are available in both 4″and 7″ widths, with your choice of either smooth or woodgrain finish.  A wide variety of colors is available to choose from, and the finish has that freshly-painted look.
