Double Hung Windows

Double Hung Window Toronto Custom Sizing Lifetime Warranty Eco Friendly


Colonial style double hung windows offer a classic look with extreme functionality. 
In the double hung style both sashes tilt in for easy cleaning.
The double hung window is equipped with a full screen to maximize comfort in your home.

  • UPVC- made from non-recycled PVC powder
  • Multi-chambered frame and sash profiles for better thermal performance and structural integrity
  • Fusion welded corners in both the frame and the sash to eliminate air and water infiltration and increase the strength and insulating value of the window
  • Triple-seal weather-stripping and step-down frame design provide superior protection against air and water infiltration.
  • Full 7/8 insulating glass with white S-Class Plus Super Spacer
  • LowE/Argon high performance glass
  • Recessed tilt latches for a clean, smooth appearance
  • High performance sloped sill, with interior and exterior drainage cavities, designed to keep water out
  • Easy tilt wash feature makes it simple to clean the exterior glass from inside your home
  • Delco’s cam-action locks pull the sashes against the weather stripping to create a tighter seal against the elements. Goodbye, drafts!


Delco’s collection of window grilles offers a range of styles, colours and patterns.  The grilles have an elegant profile, plus they offer a two-sided color scheme, allowing you to have grilles that match not only the white interior but also the exterior colour of your choice. Grille designs are typically sealed between the two panes of a thermal unit requiring no maintenance. Some grille designs can be surface mounted to the exterior of the glass on both sides of the sealed unit also known as SDL.  All grille types are shown below:

  • Colonial Grille PatternColonial

When it comes to your windows and doors, it is a fact that they can be a major source of heat loss. This is why many Canadians expect high performance windows and doors that meet ENERGY STAR standards. By choosing Delco’s windows and doors it is guaranteed that energy costs will be reduced considerably resulting in substantial savings. Low-E Glass, Argon Gas and Edgetech Superspacer are all standard properties of every window that is provided by Delco Windows.


The "E" is for "Emissivity" and the dictionary defines emissivity as "the relative power of a surface to emit heat by radiation." Low-E glass works by reflecting heat back to its source. This coating provides optimal year-round energy savings by filtering the suns energy in summer and reducing heat loss in winter. In the summer low-E products let in visible sunlight while blocking infrared and ultraviolet solar energy that drives up cooling costs and damages curtains, window treatments, carpeting, furnishings and art work. In winter low-E glass reflects room-side heat back into the room.


When the air space between the two panes of glass is filled with Argon gas, heat loss is reduced and energy efficiency is improved. This occurs because the thermal conductivity of this inert gas is lower than air. By replacing air between the window panes with Argon gas, thermal performance is increased.


Approximately 80% of energy loss through a window occurs at its edge, Super Spacer ™ thermally efficient all-foam, non-metal properties will significantly reduce such loss. This will reduce the energy required to heat or cool your home, which is great for you and for the environment. Warm Edge Technology also means that Super Spacer ™ controls condensation and mould resistance like no other spacer. Insulation works both ways. As Super Spacer ™ is less conductive than metal spacer, it blocks heat from escaping or entering your home through the glass edge, providing optimal performance and the lowest U-value in the industry. The U-value of a window is the measure of its ability to transfer heat, so windows with the lowest U value are the most efficient insulators.


There are many glass options that can be added to your window. Below are options available to you.

  • Frosted Glass

  • Triple Glass

  • Pilkington Active
    Self Cleaning Glass

  • Custom leaded
