If you’re looking for traditional-looking windows, sash windows are an excellent choice, and they’re still widely seen in both old and new homes across the nation. However, what are sash windows, how do they work and are they worth it?

Here’s everything you need to know in our beginner’s guide to sash windows.

What Are Sash Windows?

Sash windows are one of the most historical window styles on the market, often associated with traditional properties and period homes. However, they’re still chosen for modern installations thanks to their classic style, adding some heritage and character to both the interior and exterior of a property.

Sash windows consist of one or more movable glazed sashes that move up and down, achieving a window that’s great for ventilating rooms as you wish. Their long list of other design features will depend on the style and manufacturer chosen, but common elements include top and bottom rails, sills, cords and sash weights.

Sash windows work uniquely when compared to other window styles which open outwards like casement designs. The mechanism of moving the sashes up and down is supported by the use of a sash weight concealed within the lining of the box frame, counteracting the weight of the sash. It’s usually connected to a cord or rope, attached to a pulley along the top rail. The design allows for a smooth and seamless movement when operating the moving sashes.

Is Timber Still Used for Sash Windows?

Absolutely! While you may have heard about uPVC alternatives, there’s nothing as truly authentic as real timber sash windows. The timber used for modern products is of a much higher quality than wood used decades ago, so you can design a sash window replacement to your exact specifications, emulating the appearance of the original fittings.

The fine materials used means your windows will have enhanced energy efficiency to keep in warmth, while eliminating draughts, providing secure locking and double glazing. If you choose a bespoke window supplier, they can even replace your existing casement windows with timber sashes. If you do want uPVC sash windows, speak to a specialist company so that they can help you make the design as authentic as possible.
