Aesthetic Horns

Your uPVC double glazed windows have the option of decorative sash horns to be included in your finished product, adding a finishing touch to the traditional look of your windows.

Spring Balance

Each uPVC window contains spiral balances to calibrate its weight distribution, ensuring smooth and fluid operation. Our sash  windows offer effortless operation.

Top-Level Security

Each of our sliding sash double glazed windows are fitted with lockable catches for added security. We know how important the safety and security of family and property are.

Hidden Gaskets

The range of uPVC sliding sash windows come with concealed, low-level PCE gaskets as standard. Their function ensures that unpredictable weather conditions are kept at bay while staying neatly hidden.

Tilting Operation

Our sliding uPVC sash windows incorporate an ingenious pivot bar which allows the sashes to pitch inwards. This function is a great solution for ease of cleaning or to simply let extra airflow into any room.

Putting Safety First

To ensure your peace of mind, child / travel restrictors can be included to inhibit the bottom sash from being completely opened. This will keep your children safe as well as providing added security to your home.o.

uPVC Sash Windows

Our uPVC sash windows are an excellent alternative to traditional timber sliding sash windows. If you currently have wooden sash windows that look tired, worn out and let the cold air in then you’ll be amazed by how our uPVC sash windows will revolutionise your home.

Choosing Boyne Windows & Doors for your uPVC sliding sash windows will mean an elegant and traditional look for your  home. The double glazing expertise that goes into each of our sliding sash windows ensures an outstanding product every time. Attention to engineering detailing means effortless operation coupled with a classic aesthetic that will compliment your home.

We ensure the durability of each uPVC sliding sash window by utilizing the very best hardware available. Ease of use is also incredibly important, as is the ‘A’ window energy rating we have achieved. By combining these factors, we know we have beautifully tailored products on offer for homeowners. 


Superb Energy Efficiency


All our double glazing products benefit from providing you with cheaper heating bills by allowing you to get and retain energy from the sun; our largest and free natural resource.

Each uPVC window combines compact frame weatherseals and a thin, invisible metallic coating to the inner surface of the double glazed units. These functions operate together in the prevention of bad weather entering your home and by ensuring the sun’s heat is reflected back into your property. This great partnership means your home is dry and warm and, even more importantly, more cost effective to run.

We have a wide range of both external and internal colours to compliment your home.

Please note a computer or smart phone screen will never replicate the true colour
