Milestone - vs - Standard G.M.W.
• The MilestoneTM series double hung is a higher end, more historically correct window than the “standard” Green Mountain Window.
  
• The most pronounced aesthetic features that set it apart from the standard GMW (and from the competition) are the concealed balance system and hidden tilt-in mechanism.
  
• The air infiltration rating on the Milestone double hung is .11 scfm/ft2, one of – if not the – best in the industry. The overall “Design Pressure” rating is DP35 with an option of DP40 with a slightly taller sill stop. The standard G.M.W. has an air infiltration rating of .20 scfm/ft2, with an overall rating of DP30.
  
• The Milestone double hung must be installed carefully and accurately to assure optimum performance. In order to operate correctly the unit must be plumb, square and the jambs must be straight.
  
• For a more through description of the standard GMW window please see our green brochure or contact your dealer.

Why Choose The Milestone Door?
• While inspired by historical detail, it is really the options that set this door apart all others.
 
• Just ask the competition to supply a French door with 5/8” muntins, a solid mahogany sill, oil rubbed finish on the multipoint lock system and a wood swinging screen. Then admire the cross-eyed look on their face.
 
• The Milestone door will be set up to match your Milestone windows. All of the casing, divided lite, and hardware finish options will remain consistent throughout your home.
 
• The Milestone door is also a popular choice for commercial jobs because the rails and stiles can be customized to fit special hardware such as panic bars or tall kick plates. In addition, the handicapped sill option meets the code often required on commercial jobs.
