Glazing Options

HOW DOES IT WORK?

Simply put, the additional pane of glass improves heat retention by helping to keep warmth inside your home.

Our windows have achieved a high energy-efficiency rating in Ireland and the UK. By helping to retain heat inside your home, they can also reduce your energy bills.

With two specialised coatings and krypton gas-filled cavities, this triple-glazed unit is designed to deliver excellent insulation performance in Ireland and the UK.

This product’s insulation performance can add value to a property, improve its energy rating and help reduce heating costs.

KEEPING YOUR COSTS DOWN IN 2026

The difference in the cost of triple glazed windows can contribute towards the savings with regard to rising energy prices and the amount of heat that is lost through standard windows. For homeowners looking to reduce heating bills, this energy-efficient option can make a significant difference.

Triple glazing also has a further benefit in its ability to insulate against noise. Modern life involves greater dependence on transport, and many homeowners find themselves near flight paths or busy roads with increased traffic noise.

Double glazing can help reduce external noise, while triple-glazed windows may provide additional sound insulation and improve indoor comfort.

Benefits​

WHY HAVE uPVC Windows?

  • Warmth Retention

Our A-rated window range helps you contain and conserve energy while increasing your home’s value. Whether it is heat generated indoors or heat from the sun, the extra pane in our windows helps to maintain that heat and maximise energy efficiency.

  • Noise Reduction

Triple glazing has a further benefit in its ability to insulate against noise. Modern life sees greater dependence on transport and many householders now find they are on a flight path or adjacent to a busy route which has a massive increase in road traffic noise.

  • Safety

Each and every detail is an advantage to keep intruders from your home. Our windows have an additional pane which makes it more difficult to break them, this helps ensure complete safety for your family and home. All the windows come as standard with a multi-point locking system, and they are also made with top of the range materials on the market. All our windows come with guaranteed resistance.

Triple Glazing for uPVC Windows

Triple glazing is a type of window construction where three panes of glass are used instead of the standard two in double glazing. When combined with uPVC frames, triple glazing can provide excellent energy efficiency, sound insulation and security.

How Triple Glazing Works

Three Panes of Glass: Triple glazing consists of three panes of glass separated by two cavities, which are typically filled with an inert gas such as argon.

Argon Gas: This gas helps reduce heat transfer and improve insulation.

Low-E coating: Applied to one or more panes of glass, this coating helps reflect heat back into the room, improving energy efficiency.

Is Triple Glazing Right for You?

Whether triple glazing is the right choice depends on several factors:

Climate: If you live in a region with extreme or changing weather conditions, triple glazing can be particularly beneficial.

Noise levels: If your home is in a noisy area, triple glazing can help reduce external noise and create a quieter indoor environment.

Energy efficiency goals: If reducing your carbon footprint and energy bills is a priority, triple glazing may be a worthwhile investment.

Budget: Before investing in triple glazing, compare the installation cost with the potential savings on your energy bills.

uPVC Triple Glazing: A Perfect Fit for Irish Homes

To withstand Ireland’s damp, temperate climate, you need windows that combine excellent heat retention with resistance to the elements. uPVC triple glazing is an ideal fix. Its three-pane construction and argon gas spacers significantly cut down heat loss in the winter and keep heat out in the summer, ensuring year-round comfort and lower energy bills.

This means substantial savings on energy bills and improved indoor comfort. Beyond thermal performance, triple glazing excels in noise reduction, creating a peaceful interior. The low-maintenance nature of uPVC frames further adds to its appeal. While the initial investment is higher than double glazing, the long-term benefits in terms of energy savings, comfort, and reduced noise pollution make it a worthwhile consideration. When combined with proper installation and ventilation, uPVC triple glazing offers a comprehensive window system that not only withstands Ireland’s climatic challenges but also elevates the overall quality of life within a home.
