Strong steel performance and sharp detailing — the Vinyl Basement Sliding Windows makes a confident first impression every time you come home.

Delco Windows offer a self closing lock which automatically locks the sliding sashes when brought into close position.

Stops the window from opening fully, a convenient and safe way to keep the room ventilated at night.

Spring screen is an effective solution for a durable and elegant application on single hung and single slider windows.

This is a unique feature of Delco Windows for a better water drainage while reducing air and insect infiltration. Flaps only open when water is required to drain.

The thicker walls, extra chambers and contour shapes allow to reach those level of rigidity required for large units and durability.

7% to 10% thicker PVC profile walls for all awning, casement, casement fixed and picture windows, when compared to the industry average. Engineered for heavier, triple-glazed glasses and to comply with large window structural requirements.
Brickmoulds seal the gap between your window frame and exterior wall, helping prevent water intrusion while creating a clean, finish appearance.









All Delco glass packages are produced using advanced hot-melt spacer technology designed to provide industry-leading gas retention and long-term energy performance
Delco's Low-E Coating is the highest base standard glass for Canadian climates throughout Toronto, the GTA, and Ontario areas. It raises the bar and creates the new EnergyStar standard for all of Canada.

Available in dual or triple glazed, the sealed unit itself is engineered to provide protection from the elements while being durable enough to last for decades.
A nearly microscopic coating of metal-oxide, the coating acts as a reflector of UV and IR rays. Acts like sunscreen, but for your home.
Along with the window frame, the spacer bar protects against thermal transfer along the edges of the glass. Available in foam, stainless steel, or aluminum.
A completely inert noble gas, argon acts to slow down convection currents inside the sealed unit. Provides greater insulation to the unit regardless of Low-E coating.
Window grilles, also called window grids, are decorative strips of wood, vinyl, or metal that divide glass into smaller panes, enhancing curb appeal and your home's architectural style.
Choose from a variety of patterns and styles, including between-the-glass grilles for easy cleaning, interior/exterior grilles for a traditional look, or simulated divided lite (SDL) windows for the authentic appearance of divided panes.
Perfect for custom windows, replacement windows, and energy-efficient windows.




Enhance your home's architectural appeal with grilles between the glass, a popular option for homeowners seeking the classic look of divided-lite windows with modern convenience.
These window grilles feature a durable spacer bar sealed between the panes of insulating glass, providing long-lasting performance, energy efficiency, and enhanced visual appeal.
Because grilles between the glass are fully enclosed, they are completely maintenance-free, won't collect dust or debris, and never interfere with window cleaning.
Available in a wide selection of grille sizes, patterns, and shapes, these grilles are ideal for custom windows, replacement windows, and new construction projects. Two-tone grille options are also available, allowing you to coordinate interior decor and exterior finishes effortlessly.






Upgrade your home's appearance with simulated divided lites (SDL) windows, a popular choice for homeowners seeking the classic look of traditional divided-pane windows with modern energy efficiency.
SDL window grilles are permanently attached to both the interior and exterior glass, creating an authentic architectural profile without sacrificing performance.
Our simulated divided lite grilles are available in a wide range of sizes, grille patterns, and shapes, making them ideal for custom windows, replacement windows, and new construction projects.
For added design flexibility, two-tone grille options allow you to match interior decor and exterior finishes seamlessly. View the available SDL grille sizes and shapes below to find the perfect style for your windows.
