Picking the right windows for your home is a big decision, impacting the aesthetics and functionality of your property. There are lots of options available to help you make the right choice, with sash and casement windows being two of the most popular designs.
Both casement and sash windows come with their benefits and other considerations, so it’s important to know the differences before you take the plunge. Here are some of our top tips to help you make an informed choice.
Are casement windows better than sliding sash windows?
Casement windows are seen throughout UK homes, opening outward like a door and usually operated with a crank handle. They’re beloved for their versatility and modern appeal, forming clean lines and offering unobstructed views thanks to larger glass panes and fewer dividers. Casement designs often have great window energy ratings, sealing tightly when closed to minimise air leakage.
Casement windows are sometimes preferred over sash designs for their modern look or if the homeowner has become tired of challenges associated with old wooden fixtures. Traditional wooden sash windows may require regular maintenance, including painting and sealing to prevent deterioration and drafts, and may become stiff to operate.
What are the benefits of sash windows?
Sash windows are renowned for their classic vertical sliding design, consisting of two moveable panels. This window style is often associated with traditional and historical homes due to its timeless aesthetics.
One of the benefits of sash windows includes well-controlled ventilation by opening the top or bottom sash independently, helping you to maintain a comfortable indoor environment. Since sash windows open vertically, they also don’t require extra exterior space to operate, which is advantageous for homes with limited outdoor space.
Should you keep sash windows or switch to casement designs?
Ultimately, the choice between sash and casement windows depends on your personal preferences, your property’s architectural style and the functional aspects that matter most to you. If you value a timeless, elegant look with controlled ventilation, sash windows might be ideal. On the other hand, if you seek modern functionality, energy efficiency, and unobstructed views, casement windows could be the better fit.
You’ll need to think about the space you have, the aesthetics that appeal to you, energy efficiency ratings and your budget, all of which you can discuss with your window supplier. Rest assured that if you do love the look of sash windows but are concerned about their upkeep, there are lots of modern products to mitigate past concerns. This includes uPVC profiles with heritage detailing for an authentic appearance.
