The U-Max Series H540 is a marvel of European Tilt Turn Window design. While we still use the latest glass technology and materials, the H540 reaches its .14 U-Value with the sheer brute force of its mass as reflected by its beefy 4.25" profile thickness of solid Quadruple Laminated hardwood.  Add to this a 1-7/8" Triple Pane glass unit and you have a Tilt Turn Window that has few if any competitors.  The H540 keeps it simple, by giving you a robust and  substantial window or door that meets the demanding energy requirements of today & tomorrow, without using fancy new materials or technology.  The H540 shows the world that "old school" values of quality materials and craftsmanship can still lead the way!
