Instead of being built in modules with each section glued or screwed to another like most multi-paneled windows sold, our windows come in one solid frame. That makes it stronger and more durable. It also provides better protection against air and water leakage as well as more glass area and less frame.
Higher thermal protection and more strength resulting in a more durable window are possible with our multi-chamber construction.
4 1/2″ PVC Welded Frame
The 4 1/2″ frame provides more strength and durability than the more common 3 1/4″ frame other window manufacturers would offer. This frame which is larger enables the thermal pane to be installed closer to the inside of the house allowing a higher thermal protection as well as a stronger window.
Double-Glazed Low-E Argon Gas
For superior levels of energy saving and home comfort as well as UV rays protection, our double-glazed glass units are Energy Star® certified.
Triple Weather Seals
Wrapping completely the window, our seal counts three continuous layers of co-extruded flexible PVC, providing the highest level of protection from air and water infiltration.
Tremco® EnerEDGE® Warm-Edge Spacer
Tremco® EnerEDGE® Warm-edge spacer system is highly durable and possesses a lower thermal conductivity value. This results in superior thermal performance when compared to the traditional, standard aluminum spacer bar.
Interior Wood Extension cladded with PVC
Easy installation of blinds, greater window strength and durability are possible with our interior wood cladding.
High Gloss Finish
For an optimum gloss PVC finish, we rely on maximum grade PVC powder and high fabrication savoir-faire. This allows us to offer durable windows that are very easy to clean.
Decorative Cam Action Locks
For durability and security, we use our decorative cam action locks. They come in a 1-piece die-cast locking system which is anchored to a metal sash rail reinforcement.
Coil Spring Constant Force Balance System
For a smoother, quieter and easier window operation, we use our constant force balance system. This offers a consistent lift through-out the entire window path. Moreover, air leakage is decreased with the entire cavity of the window being filled.
Integrated Sash Latch
Our integrated sash latch is moulded into the sash instead of being screwed on top – like most other sah latch designs. Aside from a more modern look this sash latch design also reduces the chance of damage to the latch.
Full Screen / Half Screen Option
Choose your preference. Full screens allow you to have the top and bottom sash of the double-hung window open. This increases airflow and ventilation. Half screens only allow for either the top or bottom sash of the window to be open, but allow more natural light to enter your home.
Added Brickmould cuts down on installation time, guarantees a perfect fit when installing your window, and prevents water infiltration in the walls.
Add Colour with Hybrid PVC and Aluminum Windows
Our Energy Star® certified windows are available in Classic White PVC which offers our highest energy efficiency ratings also can be built in a Hybrid PVC and Aluminum construction which comes in five distinct colours.
Add Style with Grilles
Each windowpane will have its own look through its grilles. Depending on the style of your building, you can choose the grill that fits best.
Many grille shapes and materials are available for you to choose the ones that match your taste and the look of your home.
Choose a Glass Finish for Customized Lighting and Privacy
Light will always penetrate in case you choose textured or coloured glass for privacy or for an elegant look.
Energy Efficient Double Hung Windows

Lambden Window & Door' double hung windows use Tremco® EnerEDGE® Technology, a pre-desiccated, ready-to-apply, cellular silicone warm-edge spacer that is suitable for a wide range of insulating glass constructions in fenestration applications. EnerEDGE® spacer is inset and applied to our glass lite’s perimeter to enable fabrication of dual IG units inconjunction with a quality applied perimeter sealant.
