Sash Windows
More than just a classic frame, a sash window is a timeless design that has adorned homes for centuries. Expert repair, restoration, and installation available at Perma Seal across Edmonton Whether you’re modernising a house or remodelling a heritage one, our uniquewindow solutions mix performance with elegance.
What Is a Sash Window?
Renowned for their timeless elegance, sash windows open vertically and define classic architectural design. Though they are still a common choice in both heritage and modern construction today, you will typically see them in period homes.
Usually composed of two framed panes—or “sashes”—one placed in front of the other, it makes up a standard sash window. We more precisely refer to this style as a sliding sash window. The vertical grooves in the frames let the sashes slide naturally up and down without scraping or binding.
Counterbalances let opening and closure go more naturally. Usually concealed weights inside the frame, coupled by ropes and pulleys, enable the sash to move freely. Some designs have the weights clearly seen from the inside, giving the appearance some character.
Sliding sash windows, unlike casement, lack hinges and swing outward instead. But many contemporary models now have a tilt function, which makes cleaning them from inside the house much simpler.
Why Choose Sash Windows for Your Home or Project?
Sash windows open the ideal mix of use, history and design. Here’s the reason builders, architects, and homeowners still rank them as a top choice:
- This design is ideal for period-style constructions or heritage residences.
- Double-opening sashes enable exact control of airflow.
- Modern glass and materials increase thermal performance.
- Easy repairs and restorations can maintain individual sashes and components without complete replacement.
- A property’s exterior appeal and attractiveness are enhanced by original sash windows.
Our repair and replacement programmes guarantee decades of protection for your investment should you be thinking about upgrading.
Types of Sash Windows We Offer
At Perma Seal, we provide several styles to suit various architectural needs:
- Single-Hung Sash Windows: Single-hung windows are a conventional window type with a single moveable sash. Only the lower sash moves up and down within the frame, offering simple and dependable ventilation.
- Double-Hung Sash Windows: Double-hung windows are a classic style with two moveable sashes that glide up and down within the frame, allowing for flexible ventilation and simple operation. Both sashes move vertically—ideal for ventilation and easier cleaning.
- Sliding Sash Windows: Sliding windows, also known as glider windows, feature one or more movable sashes that slide horizontally rather than vertically like double-hung windows. These windows are designed with everyday convenience in mind. Many styles allow the sashes to tilt in, swing open, or even be removed entirely, making cleaning a breeze—no need for ladders or tricky manoeuvres.
Each sash window can be customised with a variety of materials, finishes, and glazing options. Whether you’re drawn to timeless, traditional details or want something with a more modern edge, we’ll help you create a solution that fits your home or project perfectly.
Materials and Finishes Tailored to Your Needs
We establish our sash window frames from carefully selected, premium materials so that every window guarantees style, energy economy, and longevity.
- Wood is a traditional choice, particularly for historical buildings. Our selection of wood types and treatments helps to accentuate the inherent appeal and character of your house.
- The ideal of both worlds is metal-clad wood. Strong, weather-resistant aluminium or copper on the outside complements the warmth and beauty of wood on the inside.
- Aluminium is low maintenance, sleek, and modern. Perfect for modern styles and neat architectural lines.
- Strong, low-maintenance, and great insulating composites like Fiberglass are clever, sensible choices and preserve the classic or historical exterior and the dignity of your place.
We also provide bespoke colour matching and a range of texture finishes to help your new windows blend in wonderfully and thus enhance the exterior of your building.

FAQ’s
Q: How to open the sash windows?
A counterweight or spring system will help you slide sash windows either vertically or horizontally. Double-hung windows move top and bottom panels.
Q: Could sash windows be fixed rather than replaced?
Absolutely. Many times, one may fix or replace individual sashes, cords, or glazing without taking down the entire frame. This is both cost-effective and more sustainable.
Q: Are sash windows energy-efficient?
Modern sash windows meeting current energy standards and with double glass, weather seals, and insulating frames can be rather efficient.
Q: How long do sash windows last?
A well-kept hardwood sash window can last for 100-plus years. Modern materials like fiberglass could provide less maintenance and a longer lifetime.
