Double hung windows are a classic favorite
Double hung windows are the most popular window style found in American homes. This window features two operable sashes that slide vertically within the frame – and can be raised from the bottom or lowered from the top, giving improved access to air circulation and ventilation. Double hung windows differ from single-hung windows in that both sashes operate whereas single hung windows only open from the bottom sash.
Our multi-chamber construction allows for superior thermal protection. It also adds strength to the double hung window, making it more energy efficient and durable.
Our 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 glass surface.
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.
An invisibly thin metallic coating is baked onto one or more of the glass pane 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.
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 and the associated heat loss through the insulated thermal glass unit. It also offsets water vapour to prevent condensation between the panes.
Our thermal glass units use a cellular silicone warm-edge spacer with low thermal conductivity, minimizing heat transfer between the interior and the exterior. It also allows for the natural expansion and compression due to temperature changes without failing the seal between them.
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.
Our double hung windows accomodate a very securely fit interior wood extension cladded with a thick layer of no-maintenance PVC. It allows for the easy installation of blinds or other window treatments, and results in greater window strength and durability.
We use the highest grade PVC powder and fabrication techniques which result in a high gloss PVC finish. As a result, our windows are easier to clean, more durable, and won’t fade or yellow over time.
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.
Our constant force balance system delivers a consistent lift throughout the entire travel of the double hung 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.
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.
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.
A brickmould added to the window frame at the factory cuts down on installation time, guarantees a perfect fit when installing your double hung window, and reduces the risk of water infiltration.
Our Classic series PVC double hung windows are also available in several exterior colours. These colours are baked onto external extruded aluminium profiles, offering a finish that’s extremely durable.
More Efficient.
We build our windows for maximum indoor comfort, year-round. Our windows lead national charts with the highest Energy Rating (ER) with both double and triple-pane glass – in standard configuration!
Brighter.
The extra strength of microcellular PVC allows manufacturing our windows with slimmer frames and sashes. This adds an extra 1.5” of glass in each dimension compared to ordinary PVC windows. Our internal mullions are only 4.5” wide, as opposed to the usual 6-7”. And our glass is clearer. As a result, you get more glass, and more natural light inside your home.Isn’t that why you get windows in the first place?
Stronger.
Our window frames, sashes, mullions, and brickmoulds are solid inside, which makes then stronger than the typical hollow chambers used in PVC replacement windows. All of our windows come standard with a 4.5” deep frame, 38% more than the industry standard of 3.25”. This makes them more rigid and help seal the wall opening better.As a result, our windows achieve a whopping Performance Grade of 85, levels above the nearest competitors
Add an Extra Touch with Grilles
Take advantage of our customization expertise to get a personalized window solution that gives your home a unique and distinctive look. The internal grilles allow for easy cleaning, while the external grilles simulate traditional divided lites. Any of our grille configurations can be combined with any grille type to get the exact look you desire.
