How Much Do UPVC Double Glazed Windows Cost?

Upgrading your windows is one of the most effective ways to improve your home’s energy efficiency, comfort, and value. If you’re researching how much UPVC double glazed windows cost in Ireland, this guide breaks down the real pricing factors, installation costs, and what influences your final quote — so you can budget confidently before requesting estimates.

Key Takeaways

• Cost varies by size, style, and complexity. Larger or custom designs are more expensive.

• Installation expenses typically range from £100–£200 per day (€170–€250/day) in Ireland, depending on labor complexity and regional rates.

• Regional price variations exist due to local demand, distance, and labour availability.

• High-quality materials and enhanced features (like triple glazing, security locking, or custom finishes) add to cost but significantly boost durability, insulation, and home value.

• Customization options, such as coloured frames or energy-efficient glass, impact the final price.

• UPVC windows are generally the most affordable option compared to wood or aluminium.

• Energy-efficient models can reduce heating bills and may qualify for SEAI grants in Ireland.

What Is UPVC?

UPVC (Unplasticised Polyvinyl Chloride) is a resilient, weatherproof, and low-maintenance material widely used for windows and doors. It doesn’t rot, warp, or need painting, making it ideal for Ireland’s wet climate. UPVC windows usually last 20–30 years and are fully recyclable.

How Double Glazing Works

Double glazing means two panes of glass separated by a spacer and filled with air or an inert gas (often argon). This structure acts as a powerful insulator, reducing heat loss and noise. Modern UPVC windows usually have additional features like advanced weather seals or multi-point locking.

Benefits include:

• Lower energy bills

• A quieter home

• Greater comfort in all seasons

• Improved security and property value

What does UPVC Double Glazed Cost?

The following detailed breakdowns use up-to-date Irish market data:

Average Price Per Window

Prices vary based on finish (e.g., white or woodgrain), hardware, and glass type.

Whole-House Example Costs

• 3-bed semi-detached house (9 windows):

  • UPVC double glazed: €4,050 – €9,000 (all in)

• Detached house (15 windows):

  • UPVC double glazed: €6,000 – €11,400 (all in)

In-Depth: The Key Factors That Drive UPVC Window Cost

1. Window Size & Style

• Larger sizes cost more due to materials and handling.

• Complex shapes (e.g., bay, bow, arched) require more fabrication and precise installation, increasing price.

• Sash windows cost significantly more than standard casement windows, due to their engineering.

2. Frame Colour & Finish

• White UPVC is most affordable; woodgrain or coloured finishes typically add 10–20% to the cost.

• Bespoke colour options, such as anthracite grey or dual-colour frames, require custom orders.

3. Glazing Options and Energy Ratings

• Double glazing is the standard in Ireland. U-values for standard A-rated double glazed UPVC windows range from 1.1–1.4 W/m²K.

• Triple glazing provides enhanced thermal performance compared to standard double glazing. It increases insulation levels and may be considered in high-efficiency or new-build homes. However, it also increases overall project costs. Whether an upgrade is worthwhile depends on your home’s insulation level and long-term energy goals.

• Low-e coatings and argon gas fillings increase energy efficiency, reducing household energy bills.

• BER (Building Energy Rating): Windows with low U-values help homeowners achieve better BER, essential for resale and grant eligibility.

4. Security Features

• Multi-point locking, laminated/toughened glass, and grills increase security but raise price.

• Modern UPVC windows commonly feature glass that resists shattering and frames with anti-jemmy guards.

5. Labour and Installation Complexity

• Straight swap of standard windows is fastest and cheapest.

• Replacing windows in old homes, properties with non-standard openings, or where access is tight can cost more due to extra labour, scaffolding, or making good around reveals.

• Waste removal and old window disposal fees typically range from €30–€50 per window.

6. Regional Price Variations

• Prices are highest in urban centres (Dublin, Cork, Galway) due to higher labour rates.

• Rural regions may see slightly lower pricing but sometimes longer lead times.

Energy Efficiency: Long-Term Savings & Comfort

Investing in high-performing windows offers more than immediate thermal and security improvements—it pays off on energy bills and property valuations.

Understanding U-Values and Energy Ratings

• Lower U-value = Better insulation.

• Most A-rated UPVC double-glazed windows have U-values between 1.1–1.4 W/m²K.

• Triple glazed or passive-certified options can deliver U-values as low as 0.7–0.8 W/m²K.

Impact on Your Home and Bills

• Estimated heating bill reductions: Up to 20–30% compared to single glazing, especially in older homes.

• Noise reduction: Thicker sealed units block out more exterior noise, making homes more peaceful.

• Security: Stronger frames and advanced locking mechanisms mean a safer home.

Choosing the Right Installer: Why Expertise Matters

Expert installation ensures energy performance, airtightness, and a perfect finish. Poor fitting can lead to draughts, condensation, or even invalidate warranties.

What to Ask When Getting Quotes

• Are you SEAI-registered or certified?

• What warranty is offered on frames, glass, and installation?

• Do your installers provide full disposal of old windows?

• Can you see examples of previous work or references?

Typical Labour Costs in Ireland

Installations are typically completed within 1–2 days for one to ten windows.

Popular UPVC Window Styles

Understanding different window styles helps explain why pricing varies. Certain designs require more materials, complex fabrication, or additional installation time — all of which influence cost.

• Casement Windows: Hinged on the side or top, outward-opening, versatile and popular.

• Sash Windows: Vertical sliding, often chosen for traditional Irish homes—beautiful but pricier.

• Tilt and Turn: Offer dual opening modes for easy ventilation and cleaning from indoors.

• Bay/Bow Windows: Multi-panelled, projecting windows—focal points with expansive views.

Enhanced Features That Boost Value

• Acoustic Glass: Reduces street noise; ideal for city or roadside homes.

• Solar Control: Tinted or coated glass reduces summer heat gain and glare.

• Decorative Glazing: Leaded, bevelled, or frosted glass adds personal style.

• Child Safety Locks: Give peace of mind for families.
