Home › Triple Glazed Windows Dublin
Triple glazed windows in Dublin achieve U-values as low as 0.8 W/m²K, roughly 35% better than standard A-rated double glazing, making them the right choice for passive house retrofits and coastal Dublin homes where Atlantic salt air accelerates heat loss. Our triple glazed uPVC units include argon-filled cavities and warm-edge spacer bars as standard.
As an SEAI-registered contractor, we provide the A-rated triple glazing and post-works BER documentation that lets Dublin households apply for up to €5,600 in grant support — homeowners submit the application directly to SEAI. Owen responds within 24 hours and fixed-price quotes are issued after survey, backed by a 10-year guarantee and installed by our own directly employed team.

Yes — for Dublin's damp, coastal climate, triple glazing delivers measurable returns:
Dublin homeowners typically save €400-€600 annually on heating costs compared to old double glazing. At current energy prices, triple glazing pays for itself within 12-15 years through reduced oil, gas, or electric heating bills.
North-facing rooms that never get direct sunlight, homes near busy roads (M50, N11, Luas routes), coastal properties exposed to Atlantic winds, period homes with BER ratings below C1, properties near Dublin Airport flight paths
Costs 20-30% more upfront but delivers 30% better heat retention (U-value 0.8 vs 1.2-1.6), superior noise reduction (40+ decibel reduction vs 25-30), zero condensation issues, higher BER ratings (improves resale value €3,000-€5,000)
Triple-glazing windows are a great way to improve your home's insulation, heat retention, and security. Installation services can be arranged to suit your needs, so don't hesitate to call us today. Not only will triple-glazing windows keep your home warmer in the winter and cooler in the summer, but they will also provide you with increased privacy and reduced noise levels inside your home. And because triple-glazing windows require no maintenance or replacements, you can enjoy years of trouble-free use.

Triple-glazed windows are a good choice for people who value privacy and security. Not only do they offer good insulation and protection from the elements, but they also have a lifespan of up to 30 years. They're getting more and more common now in Dublin as building codes adopt the push towards R-5 windows.
Triple glazing achieves U-values as low as 0.8 — 35% better than standard double glazing (1.2-1.6 U-value). This superior thermal performance cuts heat loss by 30%, reducing oil, gas, or electric heating costs by €400-€600 annually for typical Dublin homes. Three panes of glass with two argon-filled cavities create a thermal barrier. Low-E coatings reflect internal heat back into your rooms. Coastal dampness and Atlantic winds make heat loss through windows a major issue — triple glazing prevents condensation buildup that damages frames and promotes mould growth.
Three panes of toughened glass make triple glazing significantly harder to break than single or double glazing. Combined with multi-point locking systems: longer break-in attempt time, enhanced frame strength (70mm+ depth), shootbolt locking at top and bottom of sashes, internal glazing beads (glass cannot be removed from outside). All windows achieve PAS 24 security standard and meet Irish building regulations for residential security.
Triple glazing reduces external noise by 40-50 decibels — significantly better than double glazing's 25-30 decibel reduction. Ideal for homes near M50, M1, N11, Luas Green and Red Line tracks, Dublin Airport flight paths, busy city centre streets, DART and Commuter Rail lines. Traffic noise (70-80dB at busy Dublin junctions) reduces to 30-40dB inside — equivalent to quiet library levels. Homeowners near Dublin Airport report 60% less aircraft noise disruption.
Real-world impact: Traffic noise (70-80dB at busy Dublin junctions) reduces to 30-40dB inside, equivalent to quiet library levels.
Upgrading to A-rated triple glazing typically improves your BER by 1-2 grades (e.g. C2 to B3 or B1). Dublin properties with B1-B3 BER ratings sell for €3,000-€5,000 more than equivalent C-rated homes. Every BER grade improvement reduces annual heating bills by 10-15%. Landlords must achieve minimum D2 BER ratings by 2025. Triple glazing installation may qualify for SEAI Better Energy Homes grants (up to €5,000 depending on project scope).

Triple glazing costs 20-30% more than double glazing upfront — typically €750-€950 per window vs €600-€750 for double glazing. The extra weight also requires stronger frames and hinges, which can limit suitability for older wooden frames in period properties. Reduced solar gain is another consideration — triple glazing blocks slightly more natural heat from sunlight compared to double glazing. For south-facing rooms in Dublin that receive good sun exposure, this can mean higher heating costs on cold but sunny winter days. However, most Dublin homeowners find the benefits outweigh these drawbacks — especially for north-facing rooms, noisy locations, and exposed coastal properties.
For a full home replacement (10-12 windows), expect: Free survey and quote same day/next day, manufacturing lead time 4-6 weeks after order confirmation, installation 2-3 days for full home, clean-up and final inspection same day as installation. We work room-by-room to minimise disruption — your home remains liveable throughout. Installation includes removal of old windows, disposal of all debris, and frame sealing.
Yes — SEAI (Sustainable Energy Authority of Ireland) offers Better Energy Homes grants for window upgrades as part of whole-home retrofits. As an SEAI registered installer, your installation qualifies — you apply directly to SEAI.
Both are inert gases used to improve insulation. Argon gas (standard): Used in 95% of triple glazed windows, achieves U-values of 0.8-1.0, most cost-effective option, included in our standard triple glazing at no extra charge. Krypton gas (premium): Denser than argon provides better insulation, achieves U-values as low as 0.6-0.7, typically adds €150-€200 per window, recommended for passive house standards or north-facing rooms. For most Dublin homes, argon gas delivers excellent performance. We only recommend krypton upgrades for passive house projects or homes in extremely exposed coastal locations.
Generally no — window replacement is considered "exempted development" under Irish planning law, meaning no planning permission required. We advise checking with Dublin City Council or your local planning office before ordering. For period properties, we can match original sash proportions and use heritage-appropriate colours to satisfy conservation requirements.
