Welded Vinyl (6000 Series)

The 6000 series are our premium grade window. Using extrusions from a leading supplier of high performance polymer-based components (REHAU), this series of windows is engineered to give the best performance out of our residential series. Not only will these windows attract curbside appeal and cut down those energy bills, they will increase the value of your home because of their exceptional quality.

This product series includes Double Hung, Slider, Picture, Casement and Awning windows.

6000 Series Features:


  • Constructed with fusion welded sash and fusion welded frame. This provides greater levels of structural stability and enhances the window’s lifetime.
  • This series is designed with 50% more chambers in the frame compared to our other series, giving this premium series far superior durability and insulation.
  • The standard window frame depth is 3-1/4”and we use a 7/8” Insulated glass unit (IGU) for optimal insulation.
  • Made with 100% virgin vinyl, which provides better structural integrity and color retention than recycled vinyl.
  • Double strength glass is used for all standard sizes for increased durability.
  • Designed with a beveled face and frame, these windows will give your home an attractive curbside appeal.
  • We use a heavy duty integral lift/pull rail which provides even more structural integrity to the sash.
  • Designed with true sloped sills that force any rainfall to drain outwards and keep your home protected from the elements. These sills also give the advantage of having a larger daylight opening.
  • Auto-locking fiberglass or aluminum screens are available and made with a sturdy aluminum frame. Double hung and slider windows come standard with half screens, though full screens are available.
  • We integrate a double weather-stripped system into the design providing a weather tight performance.
  • The Double Hung and Slider models have interlocking sashes to guarantee a tight seal every time you lock your windows. Dual locks also come standard on all Double Hung over 27” wide and Sliders over 27″ high  to ensure a secure seal.

Double Hung (6100)

The Double Hung is the traditional window that is a staple for any home. At Diamond we made it even easier for homeowners to be able to clean their windows from the inside with our recessed tilt latches in both of the sashes. This means that both of the sashes are able to tilt inwards to allow for easy cleaning and maintenance.
Double hung windows come standard with ventilation limit latches, which help to prevent unwanted operation by children as well as helping to prevent against unwanted intrusions.



Picture Window (6200)

A picture window is the perfect window for homeowners looking to add natural light to any living space because of their big daylight opening while adding an upscale architectural appearance. These can be combined in a series of fixed and operable windows (Mulled Units) to enhance your house’s aesthetic appeal.


Two Lite Slider (6300-2)

Two operable sashes that slide side to side with a tilt in function to maximize your opening and make cleaning easy. Diamond’s slider windows are your go to windows for large wide openings. They offer an unobstructed view and slide with ease. Whether you’re looking for a slider for your basement or for your living space, or kitchen, we have what you need.



Three Lite Slider (6300-3)

If the 2 lite slider is not big enough, that’s no problem as we offer a 3 lite slider which will replace a very wide opening or replacing several windows. The 3 lite slider includes two operable sashes that slide side to side with a fixed sash in between. This also comes with tilt in capabilities to make cleaning a breeze. This is available in equal sashes or ¼ operable sashes with a ½ fixed sash.


Casement (6500)

A single lite sash that vents outward with a crank that opens the window to the left or right. This is available in multiple casements mulled together with cranks in either direction.



Awning (6600)

A single lite sash that vents outward with a crank from the bottom. They are an excellent addition to openings above a doorway, staircase, lofts, etc… to add natural light and ventilation.



Optional Add-ons


Grids can help add that extra aesthetic that you were looking for. We currentlyhave either Flat or Contoured profiles. Grid configurations are available in equal sqaure, diamond, or prairie pattern. Available in 2,4,6,8,9,12, or 16 lites. For custom grids, please contact our customer service department.

Grid types include between the glass (BTG) or simulated divided lites (SDL). BTG offers a smooth surface that is easy to clean while SDL offers a more traditional look.


Thermal performance of a window is improved by replacing the air between the panes of a window with either Argon or Krypton gas. This helps prevent heat loss and improves overall energy efficiency.

Argon vs Krypton: Both gases are an inert, slow moving gas that helps protect your home from energy loss, however, as Krypton is denser than Argon, this further enhances it’s energy efficiency.




Triple pane insulated glass units (IGU) are available for all window types and provides significantly improved insulation and reduced ambient noise.

Glass options include clear, low E, and double low E (Solar-ban 60/Pilkington low E).

Specialty glazings such as tinted, obscured, spandrel and tempered glass are available as well.



Fiberglass comes standard with all our windows, however, Aluminum is available if you require a stronger material for your screen.

Available in half or full screen for all windows.
