Double Hung Window Features

Our Classic Series PVC windows feature a traditional, ornate profile, which goes equally well with heritage and contemporary homes. Both sashes of our hung windows slide up and down for ventilation, and tilt in for easy cleaning. The multiple air chambers offer great insulation, while the 4.5” frame depth adds extra efficiency as well as protection against the elements.

Double Hung Windows - Multi-Chamber Construction

Multi-Chamber Construction

Our multi-chamber construction allows for superior thermal protection. It also adds strength to the window, making it more energy efficient and durable.

Double Hung Windows - 4½” fusion-welded frame

4½” fusion-welded frame

Our double hung windows come standard on a 4-1/2” deep frame, which is stronger and more durable than the standard 3-1/4” sold elsewhere. The deeper frames give extra dimensional stability and strength. It also allows for a lower sash profiles to maximize the glas surface.

Double Hung Windows - Dual-pane insulated glass units

Dual-pane insulated glass units

Two layers of glass are joined together to create a sealed hollow chamber that act as a thermal buffer. This drastically reduces direct heat transfer through the glass, as well as helps prevent condensation and ice build-up. It also helps soundproof the interior, especially in conjunction with a high-quality cellular spacer.

Double Hung Windows - Low-emissivity coated glass

Low-emissivity coated glass

An invisibly thin coating is applied onto one or more of the glass surfaces, reflecting most of the heat in the form of infrared radiation back inside the home during winter and outside during summer, while letting most visible light pass through.

Double Hung Windows - Argon gas filling

Argon gas filling

The air between the glass panes inside a thermal glass unit is replaced with argon. This inert, odourless gas is heavier than air, reducing convection between the panes. Its lower specific heat capacity reduces direct heat transfer. The argon fill hence reduces heat loss, and offsets water vapour to prevent condensation between the panes.

Double Hung Windows - Ener-Edge® warm-edge spacer

Ener-Edge® warm-edge spacer

Our insulated glass units use a cellular silicone warm-edge spacer with the lowest thermal conductivity on the market, minimizing heat transfer between the interior and the exterior. It also allows for the natural expansion and compression of glass due to environmental temperature changes without failing the seal between them.

Double Hung Windows - Multiple weather seals

Multiple weather seals

Our window seal is made up of three continuous layers that wrap around the entire window. The co-extruded flexible PVC seals offer the highest degree of protection from air and water infiltration.

Double Hung Windows - PVC-cladded interior wood extension

PVC-cladded interior wood extension

Our double hung windows use an interior wood extension that can be manufactured in any depth. This extension is cladded with maintenance-free PVC, providing a finish that does not need sealing or painting. It also allows for the installation of blinds or other window treatments, and adds to the window strength and durability.

Double Hung Windows - High-gloss finish

High-gloss finish

We use the highest-grade PVC powder and fabrication techniques which result in a high-gloss PVC finish. As a result, our double hung windows are easier to clean, more durable, and won’t fade or yellow over time.

Double Hung Windows - Decorative cam action locks

Decorative cam action locks

Our decorative cam action locks are a one-piece, die-cast metal system that is anchored to a metal sash rail reinforcement to provide exceptional durability and security.

Double Hung Windows - Coil-spring, constant-force balance system

Coil-spring, constant-force balance system

Our constant force balance system delivers a consistent lift throughout the entire travel of the window. This results in window operation which is smooth, quiet and easy to use. The system fills the entire cavity of the window to reduce air leakage.

Double Hung Windows - Integrated sash latch

Integrated sash latch

Unlike most other sash latch designs, our integrated sash latch is moulded into the sash instead of being screwed on top. Aside from a more modern look, this design also reduces the chance of damage to the latch, and is easier to clean.

Double Hung Windows - Half screen/full screen option

Half screen/full screen option

Choose your preference. Half screens only allow for either one of the sashes of the window to be covered, but allow more natural light to enter your home, and offer access to the exterior through the other sash. Full screens allow for more airflow and ventilation while both sashes are open. With their durable elegant aluminium finish, these screens won’t warp or break down over time like some of the competition.

Double Hung Windows - Added brickmould (option)

Added brickmould (option)

A brickmould added to the window frame at the factory cuts down on installation time, guarantees a perfect fit when installing your window, and reduces the risk of water infiltration.

Double Hung Windows - Durable standard colours with hybrid aluminium-PVC construction

Durable standard colours with hybrid aluminium-PVC construction

Our Classic series PVC windows are also available in several exterior colours. These colours are baked onto external extruded aluminium profiles, offering a finish that’s extremely durable.

Add Colour with Hybrid PVC / Aluminum Construction

For a more colorful look, our double hung windows, and all our windows for that matter, can be manufactured with Hybrid PVC / Aluminum construction which allows you to add colour (ivory, khaki, commercial brown, black, white) to your windows.
