Double Hung Windows - Structural Construction

Structural Construction

Most multi-paneled windows are built-in modules where each section is glued or screwed together. Our windows are engineered on one solid frame which results in a stronger, more durable window. This advanced technology results in better protection against air and water leakage. Additionally, the strength of the frame allows for a leaner design, which results in more glass and light for your window.

Double Hung Windows - Multi-Chamber Construction

Multi-Chamber Construction

Our multi-chamber construction allows for superior thermal protection and also provides greater overall strength to the window resulting in a more efficient and more durable window.

Double Hung Windows - 4 1/2″ PVC Welded Frame

4 1/2″ PVC Welded Frame

Our 4 1/2″ frame is stronger and more durable than the standard 3 1/4″ frame available from most other window manufacturers. Our larger frame allows us to put the thermal pane closer to the inside of the house resulting in better thermal protection and a stronger window.

Double Hung Windows - Double-Glazed Low-E Argon Gas

Double-Glazed Low-E Argon Gas

We use Energy Star® certified, double-glazed glass units that provide the highest levels of energy efficiency, home comfort, and also protect against UV rays.

Double Hung Windows - Triple Weather Seals

Triple Weather Seals

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

Double Hung Windows - Tremco® EnerEDGE® Warm-Edge Spacer

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.

Double Hung Windows - Interior Wood Extension cladded with PVC

Interior Wood Extension cladded with PVC

Our windows include an interior wood cladding that allows for the easy installation of blinds and other window treatments and results in greater 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 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 locking system that is anchored to a metal sash rail reinforcement to provide durability and exceptional 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 through-out 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

Our integrated sash latch is moulded into the sash instead of being screwed on top – like most other sash latch designs. Aside from a more modern look, this sash latch design also reduces the chance of damage to the latch.

Double Hung Windows - Full Screen / Half Screen Option

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.

Double Hung Windows - Added Brickmould

Added Brickmould

Added Brickmould cuts down on installation time, guarantees a perfect fit when installing your window, and prevents water infiltration in the walls.

Double Hung Window Profile Style

Our Energy Star® High Efficiency rated double hung windows are built with a solid 4½" frame with the same, modern colonial look (Symphony) as our casement and awning windows.

The Colonial Look

The Colonial Profile, which is the same as our Symphony profile for casement and awning windows, add a modern, comtemporary feel to your window.
