uPVC Sliding Sash Windows

Llanelli


Leekes has been installing quality uPVC Sliding Sash Windows in homes across Llanelli for many years. These windows are the ideal replacement for old timber or wooden products, maintaining the character and look without high maintenance issues. Contact our team now to discuss how our range of uPVC Sliding Sash Windows will improve your Carmarthenshire property.

Classical Design, Modern Performance

Our uPVC Sliding Sash Windows are popular with the Llanelli homeowner as they remain true to the timber design they are inspired by. We use a modern uPVC profile that despite having a classical look, provides you with a modern performance. Unlike timber, you won’t be blighted with any high maintenance issues that are associated with timber. Even after constant exposure to the changeable Carmarthenshire weather, this window will continue to maintain its quality look.

A uPVC Sliding Sash Window is a clever way of maintaining the traditional look of your Llanelli home or adding character to a new build. The design provides you with ventilation without compromising on the security of your property. The bottom sash lifts vertically to sit beneath the top half. For those who want to secure their home further, our uPVC Sliding Sash Windows can allow for the two sashes to be tilted.

Benefits of Our uPVC Sliding Sash Window Range


We appreciate that every Llanelli property is different. That’s why at Leekes, we offer uPVC Sliding Sash Windows that can be customised to fit every type of Carmarthenshire home. You’ll be able to opt from a range of colour options to fit in perfectly with your property. If you live in a more traditional property, a woodgrain foil might be better, or you might want something brighter for a modern home.

Colour is not the only customisable factor of our uPVC Sliding Sash Windows. You can choose to have Georgian Astral bars or single panes fitted on your window to give it an authentic appearance. Whatever you need for your property, we will offer a window that provides the perfect fit for your Llanelli home.


It’s important when purchasing any double glazing product, be it our uPVC Sliding Sash Windows or a door, that it secures your home. Leeke’s sash design does just that. The window is fitted with several safety features, including key operated travel restrictors, security bars and sash locks.

The Llanelli homeowner can improve the security of our uPVC Sliding Sash Windows further through Yale locking. These locks, when combined with the double glazing and multi-chambered uPVC frame, provides the best security across the whole of the frame. If you require further peace of mind to choose our sash window, it has been manufactured to Secured by Design standard and built in regulation with the latest British Building Regulation Standards.


Our range of uPVC Sliding Sash Windows will save the Llanelli homeowner money on energy bills. The multi-chambered profile works alongside the panes of double or triple glazing to maintain a warmer property for longer. Due to this, you’ll benefit from a comfortable temperature within your Carmarthenshire home throughout the year, even in the cold winter months.

As your Llanelli home stays warmer for longer, you’ll rely less on your central heating. This will lead to lower energy bills and help shrink the carbon footprint of your home. If you want to improve your home’s thermal performance further, our uPVC Sliding Sash Windows can be fitted with triple glazing. This creates an extra barrier to trap heat and against uninvited visitors.


When buying our range of uPVC Sliding Sash Windows or any home improvement product for your Carmarthenshire property, you want to be sure you’re getting the best. By choosing Leekes, you’re opting for a FENSA and TrustMark accredited company who is a proud member of the Ultraframe Ultra Installer network. Our quality was further recognised at the G19 Awards, where Leekes was named as a finalist for Installer of the Year and Sustainability Initiative of the Year.
