Replacing your doors is a big decision, and the cost is usually the first thing that puts people off. The good news is that the Irish government, through the SEAI (Sustainable Energy Authority of Ireland), offers grant money to help homeowners cover the cost of energy-efficient door upgrades – and aluminium doors can qualify.
This guide covers what the grant pays for, whether your aluminium door choice is eligible, how much you could get back, and how to get the ball rolling with Thermoglaze.
What Is the SEAI Grant?
The SEAI Better Energy Homes scheme pays grants to homeowners who upgrade their home’s energy performance. The scheme is funded by the Irish government and is designed to reduce energy bills and cut carbon emissions from Irish homes.
To be eligible, you need to tick a few boxes:
- You own and live in the home as your main residence
- The house was built and occupied before 2011
- The work is done by an SEAI registered contractor
- The products meet SEAI’s minimum energy performance requirements
If your home ticks all of those, you can apply for support across a range of upgrades – windows, doors, insulation, heating, and more.
See the full SEAI Windows & Doors Grant details on our website before you apply.
Can You Actually Get a Grant for Aluminium Doors?
Yes – but not every aluminium door automatically qualifies. The grant is based on energy performance, not material.
What the SEAI looks at is the U-value of the door. A U-value measures how much heat escapes through a surface. The lower the number, the less heat gets out, and the better the door performs. For an external door to qualify under the current scheme, it needs a U-value of 1.6 W/m²K or below.
Good quality aluminium doors with thermal breaks hit that number without trouble. Cheaper, non-thermally-broken aluminium doors may not.
What Does “Thermally Broken” Mean?
Raw aluminium conducts heat – press your hand against an untreated aluminium frame on a cold morning and you will feel it straight away. A thermally broken door solves this by inserting a non-conductive material between the inner and outer sections of the frame. Heat cannot travel across it, so the frame stays warmer inside and the door performs far better overall.
Most quality aluminium doors sold in Ireland today are thermally broken. At Thermoglaze, all our aluminium door options are built with this in mind.
How Much Grant Money Is Available?
Under the SEAI Better Energy Homes scheme, homeowners can claim up to €5,600 when replacing windows and external doors with energy-efficient alternatives.
A few things worth knowing:
- The grant is paid to you directly after the work is completed and signed off
- You can only make one application per property
- The more upgrade work you include in the same application, the more grant support you can access
The grant rarely covers the full cost of a door installation, but it takes a meaningful chunk off the bill – and when you factor in reduced heating costs over the following years, the numbers make good sense.
What Types of Aluminium Doors Does Thermoglaze Supply?
Thermoglaze stocks four main types of aluminium door, covering most situations a homeowner is likely to need:
- Aluminium Entrance Doors
The go-to for front doors. Solid, secure, and built to last. You can pick from a wide range of RAL colours so the door fits the look of your house rather than clashing with it.
- Aluminium French Doors
Good for opening a room onto a garden or patio. Our aluminium French doors bring in plenty of light through the glass panels while still meeting energy performance requirements.
- Aluminium Sliding Doors
Where you do not have room for a door to swing open, sliding doors are the practical fix. Slim frames, large glass areas, and smooth operation make them a popular pick for modern homes.
- Aluminium Bi-Fold Doors
Our aluminium bi-fold doors fold back against the wall to give you a wide, unobstructed opening. They work particularly well between a kitchen or living room and a rear garden.

Is an Aluminium Door Worth It If You Do Not Qualify for the Grant?
Honestly, yes. The grant helps, but it is not the only reason to choose aluminium. Here is what you actually get from a good aluminium door regardless of grant support:
- No warping or rotting – aluminium holds its shape in all weather
- Very little maintenance – wipe it down now and then and it stays looking new
- Strong security – multi-point locking as standard across our range
- More glass, less frame – aluminium’s strength means thinner frames and bigger glass panels
- Looks the part – the slim, clean lines of aluminium suit both modern and period homes
If you like the look of aluminium but want a timber feel on the inside, our alu clad doors give you aluminium on the outside with a timber interior – a combination a lot of our customers go for.
Conclusion
Aluminium doors can qualify for the SEAI grant in Ireland – as long as they meet the U-value requirement and you use a registered contractor. The grant can cover up to €5,600 towards windows and doors combined, which is a serious saving on a full door replacement project.
At Thermoglaze, we stock aluminium doors that meet SEAI standards, we know the application process, and we handle everything from quote to installation. If you are thinking about new doors, give us a call or drop into one of our Dublin showrooms and we will take it from there.

FAQs
1. Can I claim the SEAI grant for just one door?
Yes. You do not have to replace every door in the house. You can apply for a single external door as long as it meets the U-value requirement and the installer is SEAI registered.
2. Does the type of glass in the door affect grant eligibility?
It can. The overall U-value of the door – frame and glass combined – is what SEAI measures. Double or triple glazed units generally help bring the total U-value down to qualifying levels.
3. How do I know if a specific door model qualifies?
Ask us. When you contact Thermoglaze, we can check the product’s U-value data and tell you straight away whether it qualifies under the current SEAI scheme.
4. Can the grant be used alongside other SEAI measures?
Yes. You can include windows, doors, insulation, and heating upgrades in the same SEAI application. Doing more work in one application typically means more grant money overall.
5. Do I pay upfront and get the money back later?
Yes. You pay for the work upfront and SEAI reimburses the grant amount directly to you after the installation is signed off and verified.
6. Is there a closing date for the SEAI grant?
The Better Energy Homes scheme runs year-round, but grant amounts and terms can change. Check our SEAI grant page or contact us for the latest figures.
7. How long will an aluminium door last?
A properly installed aluminium door will last 40 years or more with minimal upkeep. The material does not corrode, rust, or change shape over time.
8. What colour options are available?
We offer a wide range of RAL colours with matt, gloss, and dual-colour finishes available. You can choose a different colour for the inside and outside of the door if needed. Come into our Swords or Rathgar showroom to see physical samples.
9. What security standard do your aluminium doors meet?
Our aluminium doors come with multi-point locking as standard. If you have specific security requirements, talk to our team and we can point you towards the right product.
