uPVC Windows

Why Choose uPVC Windows for Your Home

Modern uPVC windows deliver an outstanding combination of energy efficiency, security, durability, and low maintenance that no other window material can match at the same price point. Our tilt-and-turn opening system is the gold standard for Irish homes - it allows the window to open inward from the top for secure night ventilation, or swing fully inward for easy cleaning from inside. Unlike traditional casement windows, there are no external hinges to corrode and no reaching out of upper floor windows to clean the glass. Frames are precision-engineered with multi-chamber profiles that trap warm air and dramatically reduce heat loss, directly improving your home's BER rating. Every window is custom-measured and manufactured to the exact dimensions of your openings, guaranteeing a draught-free, weathertight seal from day one.

Our uPVC Window Range

We supply and professionally fit four core window and door configurations to cover every room and application in your home:

• Two-Part Windows – One fixed pane and one tilt-and-turn sash. The ideal solution for kitchens and utility rooms. Compact, practical, and highly energy-efficient with energy-saving double glazing as standard.
• Three-Part Windows – A central tilt-and-turn opening with two fixed side panels. Perfect for living rooms, bedrooms, and home offices where a wider glazed area is needed without compromising on ventilation control.
• Balcony Blocks – A fixed window section combined with a full-height tilt-and-turn door in a single coordinated unit. The standard solution for balcony and terrace access - providing light, ventilation, and secure outdoor access in one efficient frame.
• Loggia Glazing – A four-section configuration with two central tilt-and-turn panels flanked by two fixed outer sections. Designed to fully enclose loggias and large balconies, transforming open spaces into warm, usable living areas throughout the year.

All configurations are available across our full range of profile systems, from budget-friendly entry-level options to high-performance six and eight-chamber frames engineered for maximum energy saving. Choose different profile systems for different areas of your home depending on your budget, BER targets, and insulation priorities.

Profile Systems - Finding the Right Specification

The heart of any uPVC window is its profile system - the engineered PVC frame that determines thermal performance, structural strength, and long-term durability. We offer a carefully selected range of profile systems to suit every project and budget:

• S400 (4-chamber, 58mm) – A practical and affordable entry-level profile ideal for balconies, outbuildings, and applications where budget is the primary consideration. Solid thermal improvement over single-glazed or aluminium alternatives.
• S500 (5-chamber, 60mm) – A five-chamber European-manufactured profile at an accessible price. Recommended for apartments, private houses, and heated balconies. A reliable mid-range specification delivering genuine energy savings.
• S700 (6-chamber, 70mm) – A six-chamber profile offering superior thermal resistance of 0.85 m²°C/W. The most popular choice for residential properties, meeting all standard building regulation requirements for window thermal performance. Excellent value at the premium end of the mid-range.
• V90 (Class A, 6-chamber, 90mm) – A German-manufactured Class A profile with a 90mm frame depth, delivering maximum thermal insulation. The specification of choice for energy-efficient homes, BER A-rated properties, and homeowners who want the best long-term performance available.

Frequently Asked Questions

What is a tilt-and-turn window?

A tilt-and-turn window has a single sash that can open in two ways. Tilting inward from the top provides secure background ventilation - the window can be left open even in rain without draughts, and it cannot be pushed fully open from the outside making it much safer for upper floors. Turning fully inward like a door gives full access to both faces of the glass for easy interior cleaning, making it particularly practical for first and second floor windows where external cleaning is difficult.

How do uPVC windows affect a home's BER rating?

Windows are one of the leading sources of heat loss in Irish homes. Upgrading from single-glazed or older double-glazed windows to modern multi-chamber uPVC windows with energy-saving glazing units can significantly improve a property's BER rating. Higher-specification profiles such as our S700 and V90 deliver thermal resistance values that comfortably exceed standard building regulation requirements, contributing meaningfully to both your BER score and your annual heating costs. We can advise on the best specification for your target BER during your free home survey.

Are uPVC windows low maintenance?

Yes. uPVC frames require no painting, varnishing, or staining and will not rot, warp, or corrode regardless of weather conditions. Cleaning is straightforward - a wipe with warm soapy water keeps the frames looking like new. The grey sealing gaskets used throughout our window range are specifically chosen for long-term durability and colour stability, and will not discolour over time. With proper installation and occasional hardware lubrication, our uPVC windows are designed to perform trouble-free for decades.
