The new funding program from the Sustainable Energy Authority of Ireland (SEAI) is a breakthrough for the housing market, offering up to €5,600 in support for replacing windows and doors. Find out how much you can save, what to look for, and why 2026 is the perfect time to replace old windows or doors.
2026 Grants: A Warmer Home and Better Energy Efficiency
The changes introduced in March to the SEAI grant program create an excellent opportunity for homeowners to invest in the future of their houses or apartments. The new rules simplify the retrofit process, allowing windows and doors to be replaced without the need for a full renovation at once.
Modern Joinery: Quality That Makes a Difference
What parameters should you consider when choosing joinery with SEAI funding?
Above all, it’s worth selecting high-quality products made from certified materials, which enable a fast and effective improvement in a building’s energy performance and remain cost-effective in the long run. Pay attention to thermal transmittance values – the lower the value, the better.
- DAKO windows achieve a U-value starting from 0.75 W/m²K, placing them among the most energy-efficient solutions on the market.
- Entrance doors with a Ud value starting from 0.71 W/m²K ensure excellent insulation, eliminating thermal bridges and reducing heat loss in the entrance area.
This is a long-term investment: efficient, energy-saving joinery can reduce your annual energy costs by up to €900.
Innovative Solutions Designed for Irish Conditions
When choosing new windows and doors, it’s worth opting for products with parameters that will noticeably improve living comfort and reduce energy bills. DAKO products have proven their performance in Ireland and the UK, where wind, humidity, and rain regularly test building tightness.
- Advanced triple-glazing units with warm edge spacers effectively reduce condensation – especially important in humid island climates.
- Multi-point sealing systems ensure full watertightness and resistance to strong wind pressure.
- Certified hardware from reputable suppliers additionally protects interiors from cold infiltration, even in demanding coastal areas.
Thanks to a wide range of designs (from minimalist, modern styles to more classic forms), our models fit perfectly into both new builds and renovation projects.
