Since Ultrex is significantly stronger than vinyl or Fibrex, the frame profile can be slimmer.
Infinity From Marvin Frame
Instead of the white, shiny, and plasticky feel and look of vinyl, Infinity from Marvin patented an amazing co-extruded acrylic cap. The acrylic cap is 3x thicker than a painted finish. It is the first and only exterior finish on a window that is verified by AAMA’s 624-10 & 625-10 rating. This is the highest rated exterior finish that exists. You need this type of product in our extreme weather!
