Double Hung Window Construction Features

  • Precision Mitred, Fusion Welded Frames & Sashes

    Both the frame and sash are welded simultaneously using the latest Fusion Technology - which heats the vinyl and then under pressure fits the vinyl members together forming a super strong weld.
  • Dual Interlocking Rails

    Both top and bottom sashes overlap at the interlocking rail to form an airtight seal.
  • Stainless Steel Pivot Shoe

    Patented shoe lock that allows the window to rotate for easy indoor cleaning.
  • Finger Latch

    Our low profile design keeps the thumb latch inside the sash frame for easy operation when you need to tilt the windows in for cleaning.
  • Standard & Custom Colours

    Solar Bond™ paints are weather and fade-resistant and come with a 15-year warranty. 14 standard colours or an endless number of custom colours are available. Standard Colours: White, Cream, SDT, Sable, Grey, Hickory, High Gloss Brown, Gentek Commercial Brown, Sandlewood, Pebble, Dover Grey, Cashmere, Forest Green, and Black.
  • Fly Maze

    As a standard practice, Armor installs a sponge-like insect guard inside our hollow multi-chamber frames. This prevents insects from nesting or entering through the window frame.
  • Triple Weather Seals

    Santoprene bulbs in combination with high fin pile weatherseals virtually eliminate air infiltration.
  • Constant Force Balances

    Constant-Force spiral assembly for smooth sash operation.
  • AdvanceEdge® Spacer

    Our AdvanceEdge® Spacer Technology is made of the world’s finest 100% polymer foam, non-metal technology. The foam matrix is breathable and works fast to absorb moisture and reduce condensation. Our Spacers outperform those from our competitors in the industry’s toughest durability tests – lasting a simulated 90 years!
  • Sash in Pocket Sill

    When closed it forms a water tight and air tight seal.
  • Self Closing Locks

    Self closing locks for ease of operation and added security.
  • Drainage Flaps

    Unlike other companies that just punch holes, we use flaps that only open when water needs to drain out.
  • Full Screen Overlap

    Full screen with overlapping frame keeps bugs and debris outside while the steel pins allow for easy removal and cleaning.
  • Flip Lock

    The Armor Flip Lock combines intuitive functionality with a sleek, ergonomic design.<br>It is an Innovative automatic lock for Hung and Slider windows. Easy to install and serve as a visible reminder.

double hung window 2

Double hung windows are typically tall, narrow and operate using two sashes that move up and down. Double Hung windows provide the customers with the ability of opening tilting inwards towards themselves for easy cleaning and maintenance. This “double sash” open and close provides a wide range of ventilation combinations for controlled air circulation.
