Double Hung Window Features
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.
4-1/2” fusion-welded frame
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.
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.
Low-emissivity coated glass
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.
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 and the associated heat loss through the insulated thermal glass unit. It also offsets water vapour to prevent condensation between the panes.
Ener-Edge® warm-edge spacer
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.
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.
PVC-cladded interior wood extension
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.
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.
Coil-spring, constant-force balance system
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.
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.
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.
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 double hung window, and reduces the risk of water infiltration.
Durable standard colours with hybrid aluminium-PVC construction
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.
Energy Efficient Double Hung Windows
The manufacturing process of all Energy Star® certified double hung windows installed by Nordik Windows and Doors are audited by an independent accredited certification body and approved by Natural Resources Canada. Our windows and doors carry the Energy Star® label showing their rating.
