Stronger.

Our RevoCell^® window frames, sashes, mullions, and brickmoulds are solid inside, which makes then stronger than the hollow chambers used in regular PVC 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 hung windows achieve a Performance Grade of 40, one of the best in this product category.

Brighter.

The extra strength of microcellular PVC allows manufacturing our hung 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 what you put windows in your wall for?

Hung Window Gallery

Take a look at this gallery to see what our Hung windows can look like installed in a home.

Custom Is The New Norm

Gone are the days when window companies dictated what your home should look like. Every single window we build is as unique as you want it. From factory finishes to custom paint, decorative grilles or simulated divided lites, textured or tinted glass, the combinations available are virtually endless.

Add some colour

Most homeowners get their replacement windows in stock white, which is a great all-around colour. But you don’t have to: our comprehensive palette of exterior factory finishes will match any home style and help elevate its look.

Standard colours

Our windows’ interior colour is white, but exterior colours are also available in several affordable factory finishes. Our standard colours are engineered in cap stock (coloured PVC) for lighter tones and durable, architectural-grade laminate for the darker tones. They are extremely colourfast and and more durable than paint. We also offer a full-black (exterior and exterior) on select windows. Please contact us to inquire about the availability of custom-painted colours.

RevoCell Hung and Slider mPVC windows are offered in a variety of colours.

Grilles Patterns and Styles

In the old days, large panes of glass could not be manufactured cost-efficiently, so windows were filled with many smaller pieces of glass held in the sash by bars called muntins. These divided lite looks have become a sought-after architectural element, especially on traditional home styles. Take advantage of our window customization expertise to elevate the look of your new windows.

Internal grilles are installed between the panes of glass, inside the the insulated glass unit. This allows for the easiest window cleaning. Our internal grilles are available in a variety of profiles, sizes, and finishes.

An example of a diamond patterned grille in a Nordik Window.

Simulated divided lites (SDL) are external grilles. They are applied on the exterior of the insulated glass unit and give a more realistic muntin appearance. Like internal grilles, our SDL’s are available in multiple profiles and finishes.

Grille Patterns

We offer a variety of patterns for window grilles. Here are a few of the most popular ones. You can mix and match internal and external grilles to get the exact style your require.

Rectangular

This classic divided-lite look offers a traditional Old-World aesthetic. Works equally well on traditional and newer homes, adding a timeless elegance.

Partial Covering

Our grilles can be aplied to a portion of the window only. Combined with an SDL profile, you can also reproduce a hung sash appearance on a casement window.

Contour

Contour grilles go around the perimeter of the sash. Often associated with the Prairie School style, they add a artsy touch that’s distinctively North American.

Diamond Pattern

The diamond pattern can add an artistic touch to a traditional home. The understated charm of thin grilles adds extra interest from up close.

Divided Lites

Our grilles can be aplied to a portion of the window only. Combined with an SDL profile, you can also reproduce a hung sash appearance on a casement window.

Specialty Glass

We also offer some alternatives to clear glass in your windows. Tinted glass can be used to lower light levels, or to alter the colour balance indoors. Textured glass adds a degree of privacy as well as decorative interest, while letting natural light inside.

Hung Window FAQs

Hung windows are a classic choice for their simplicity, ease of use, and timeless appeal. Whether you prefer single or double-hung styles, these windows offer great ventilation and are easy to maintain. In this FAQ section, we’ll answer your questions about hung windows and explain how our RevoCell® technology ensures top-tier performance, energy efficiency, and long-lasting durability for your home.

What is a hung window?

Hung windows are vertical sliding windows that come in two main styles: single hung (only the bottom sash moves) and double hung (both the top and bottom sashes move). They're a timeless, space-saving choice for many areas of the home.

Where are hung windows typically used?

Hung windows are popular in bedrooms, bathrooms, and living spaces. Their vertical operation makes them ideal for tighter exterior spaces like walkways or patios where a window that swings outward might not work.

What makes RevoCell^® hung windows better?

RevoCell^® hung windows are built with solid-core microcellular PVC, offering next-level performance and durability:

Superior insulation from the solid-core frame, minimizing heat transfer and improving energy efficiency.
Fusion-welded corners for airtight performance and long-term durability.
Slim profiles for a larger glass area and enhanced natural light.
Low-maintenance finish that won’t rot, crack, or peel over time.
Smooth sash movement with reinforced hardware and balance systems.

Are RevoCell^® hung windows energy-efficient?

Yes! RevoCell^® hung windows exceed ENERGY STAR® standards thanks to their advanced insulation, triple weatherstripping, and high-performance glass options that help keep your home cooler in summer and warmer in winter.

What is the difference between single hung and double hung windows?

Single hung – Only the bottom sash moves; the top sash is fixed.
Double hung – Both sashes move up and down for improved airflow and easier cleaning.

Double hung windows are often preferred for upper floors and areas where cleaning both sides from the inside is a plus.

Do hung windows tilt in for cleaning?

Yes, both single and double hung RevoCell^® windows feature tilt-in sashes, allowing you to clean the exterior glass safely and easily from inside your home.

How secure are RevoCell^® hung windows?

Very secure. RevoCell^® hung windows include a multi-point locking system and reinforced sashes that resist forced entry. The durable mPVC construction adds an extra layer of protection.

Are hung windows easy to maintain?

Absolutely. Just occasionally clean the glass and vacuum the tracks. The tilt-in sashes make cleaning effortless, and the solid-core frame means no sanding, painting, or sealing is ever needed.

Can I customize my hung windows?

Yes. Nordik offers a wide variety of customizations, including grille patterns, exterior and interior color finishes, hardware options, and energy-efficient glazing.

Do hung windows provide good ventilation?

Double hung windows are excellent for ventilation, especially when both sashes are open—warm air escapes through the top and cool air enters through the bottom. Single hung windows offer great airflow as well but with one operable sash.

Are hung windows a good choice for small rooms?

Yes! Hung windows are perfect for compact spaces because they open vertically without protruding outward. They’re also ideal for walkways, patios, and areas with limited exterior clearance.
