Upgrade Your NJ Home with Double Hung Windows

What Are Double Hung Windows?

Double hung windows feature two operable sashes that slide vertically within the frame. Unlike single hung windows, both the top and bottom sashes can open, giving you flexible ventilation options. Both sashes also tilt inward, making them much easier to clean from the inside of your home. Their balanced look and versatility have made them a favorite style for generations of New Jersey homeowners.

Why Choose Double Hung Windows for Your Home?

When it comes to replacement windows, double hung models are the clear favorite for families in Trenton and the surrounding areas. Homeowners choose them because:

• Effortless Cleaning: Tilt-in top and bottom sashes let you clean glass from inside your home, no ladders needed.

• Energy Savings: Reduce heating and cooling costs thanks to insulated frames, advanced weatherstripping, and high-performance glass.

• Classic Style: Their balanced design works with both historic homes in Trenton and newer construction in nearby communities.

The OKNA 600 Series Difference

Not all windows are built the same. The OKNA 600 Eco-Pro Double Hung window offers superior design, security, and performance compared to many competitors.

Slim Frames for More Glass

OKNA’s narrow frames allow more natural light and larger views. Other manufacturers use bulky vinyl frames that shrink the glass space and look clunky. With OKNA, you’ll enjoy bigger views and a sleeker finish (and a little more sunshine for your morning coffee).

Smooth Tilt-In Cleaning

Both top and bottom sashes tilt in easily, making cleaning faster and safer. The interlocking design keeps the sashes steady and reliable when in use, so you can clean with confidence.

Even better, you’ll finally win the battle against those mysterious outside smudges without having to juggle a ladder.

Reinforced Hardware & Locks

OKNA 600 hardware combines style and strength. Brass locks are available in white, antique brass, brushed nickel, and bronze to match your home’s design.

A high-density composite reinforcement inside the locking sash ensures wide windows don’t bow, while vent latches and optional window opening control devices (WOCD) let you ventilate securely.

Built for Strength & Longevity

The OKNA 600 is engineered to last. Their fusion-welded sashes and frame corners prevent gaps. The heavy-duty block and tackle balance system is tested for 28,000 cycles, and the windows are independently tested for high wind loads, including structural performance appropriate for coastal storms.

Energy Efficient by Design

OKNA windows use advanced insulation to help reduce energy consumption. Foam-filled extrusions are available across the 600 Series. Low-E glass with argon gas fill reduces heat transfer, with a triple-pane upgrade available.

Triple weatherstripping and a HeatSeal spacer improve thermal performance and provide better acoustic insulation, keeping air and water infiltration out.

Exterior Design & Water Management

A beveled, wood-like exterior adds elegance and curb appeal. Rigid uPVC resists fading and chalking, maintaining its finish for years. The sloped sill system channels rainwater away from your home, while a sill dam wall mortised into the jamb adds strength and lowers the chance of leaks.

(In other words: no water sneaking in where it doesn’t belong.)

Everyday Convenience and Security

OKNA double-hung windows also provide convenience and security with:

• Spring-loaded vent latches that let you keep the sashes partially open for safe ventilation. This means you can enjoy fresh air while keeping safety in mind.

• Slim-profile sash locks that are built to last and designed to keep your windows secure.

• Half screens are included with each window, with upgrades to full screens available. This flexibility allows you to match your home’s ventilation needs and style preferences.

Your windows should fit your home’s design as well as your lifestyle. With OKNA double hung windows, you can choose:

• Colors: Euro-White, Almond, Adobe Gray, Cocoa, Matte Bronze, plus hardware finishes in Brushed Nickel and Antique Brass.
