Choosing a new front door is one of the bigger decisions you’ll make for your home. It sets the tone for your property from the street, it has to handle Irish weather year-round, and it needs to keep your family secure. Two names that come up regularly for Dublin homeowners looking at the premium end of the market are Internorm and Palladio – and for good reason. Both are strong products. But they’re not the same, and which one suits you depends on what you’re actually looking for.
At Thermoglaze Windows & Doors, we supply and install both. This guide gives you a straight look at each, so you can make an informed decision before you get in touch with us.
What Is an Internorm Front Door?
Internorm is an Austrian manufacturer and one of the largest window and door producers in Europe. Their entrance doors are built from aluminium and are designed to perform in terms of both energy efficiency and visual impact. Thermoglaze is an official Internorm partner in Ireland, which means you’re getting the genuine product backed by local expertise and installation.
Key Features of Internorm Front Doors
- Aluminium construction – built to last with minimal maintenance over time
- Wide design range – available in full door leaf or with glass cutouts, classic or contemporary
- Extensive colour and finish options – enough variety to match any new build or renovation project
- Strong thermal performance – aluminium profiles built for insulation, not just looks
- Very low maintenance – no painting, warping, or rotting to worry about
The Internorm front door suits homeowners who want a door that reads as architectural – clean lines, a quality finish, and a look that holds up over decades rather than years. If your home is modern or you’re going for a specific design statement, Internorm tends to be the stronger fit.
What Is a Palladio Composite Door?
Palladio is an Irish-owned company and a market leader in composite doors on this island. That matters – an Irish-made product, built with the Irish climate in mind. The Palladio door range is constructed from fibreglass monocoque (single-piece) construction, which means no warping, no bowing, and no shrinkage over time.
Key Features of Palladio Composite Doors
- Irish-owned and made – designed specifically for the Irish and UK climate
- Monocoque fibreglass construction – one solid piece, which resists the movement that affects timber and uPVC doors over time
- 28 designs across 13 colours – a large range for both traditional and modern homes
- 10-point locking system as standard – PAS 23/24 approved and Secured by Design certified
- Triple-glazed glass panels as standard – toughened safety glass throughout
- U-value of 0.98 (combined with triple glazing) – strong thermal performance for Irish homes
- Solid door leaf U-value of 0.205 – one of the best insulation figures in the composite door market
Palladio doors appeal to homeowners who want strong security credentials, proven weather resistance, and a composite product with a real track record in Ireland. They also come with a 10-year guarantee, which gives peace of mind on what is a long-term purchase.
Internorm vs Palladio: A Direct Comparison
Material
Internorm uses aluminium. It’s a premium, rigid material that gives a sharp, architectural finish. Palladio uses fibreglass composite. Both materials outperform uPVC in durability and thermal performance, but they suit different property styles and buyer priorities.
- Aluminium (Internorm): Best for contemporary homes, new builds, properties where design is the primary driver
- Fibreglass composite (Palladio): Best for period homes, traditional streetscapes, or buyers prioritising security ratings and insulation figures
Security
Both are strong options, but Palladio is particularly notable here. The 10-point locking system, PAS 23/24 approval, and Secured by Design certification make it one of the most security-credentialled composite doors available in Ireland. If this is your main concern, Palladio hall doors are worth serious consideration.
Internorm aluminium doors also offer multi-point locking and robust hardware, so they’re not lacking in security – but Palladio’s certifications are a clear talking point.
Thermal Performance
Both products perform well for Irish homes, where keeping heat in is a practical priority rather than just an energy rating exercise.
- Palladio’s solid door leaf has a U-value of 0.205 – very strong for a composite door
- Combined with triple glazed glass, the overall U-value is 0.98
- Internorm aluminium doors are engineered for thermal efficiency and are compatible with high-performance glazing options
If you’re looking to support a broader home energy upgrade – and potentially apply for an SEAI grant – both options are worth discussing with our team to confirm current eligibility.
Design Options
Palladio gives you 28 designs across 13 colours. Internorm gives you a full range of finishes, colours, and profiles – both with full door leaf and glass panel options. Neither range is limited, so design shouldn’t be the deciding factor unless you have a very specific requirement that one clearly meets.
Maintenance
- Internorm aluminium: Essentially maintenance-free. Wipe clean, no repainting required.
- Palladio fibreglass: Also very low maintenance. Fibreglass doesn’t fade, warp, or rot, and holds its colour well without repainting.
Both beat timber hands down on maintenance, and both are a step above standard uPVC in terms of long-term performance.
Which Door Is Right for Your Home?
There’s no single answer here, because the two products are genuinely different in character.
Choose Internorm if:
- Your home is a modern new build or a property with a contemporary aesthetic
- Design and kerb appeal are your primary drivers
- You want a clean aluminium finish that reads architecturally
- You plan to explore Internorm windows as well and want a matched system
Choose Palladio if:
- Your home is a period property or a traditional Dublin terraced house
- Security certification (PAS 23/24, Secured by Design) is important to you
- You want an Irish-owned product built specifically for this climate
- You prefer a composite door with strong insulation figures and triple glazing as standard

Conclusion
Both Internorm and Palladio are genuinely strong front door options for Irish homes – they’re just built for slightly different buyers.

Palladio composite doors suit buyers who want certified security, proven insulation figures, and an Irish-made product at a competitive price point.
