The coastal lifestyle is simply fabulous – you get amazing scenery, access to the beach and an incredible view during your walks. However, there are also some obstacles that you (and your home) may need to face. Salty air, high winds and humidity can influence your property greatly. And let us tell you – your windows are the first to battle with harsh conditions. So what actually works? In short, aluminium and uPVC windows are the most reliable choices for coastal homes. When it comes to opening styles, casement and fixed options tend to perform best.
In this guide, we’ll explore this topic in more detail. You’ll also get some recommendations from Fenbro experts. Let’s dive in!
Best windows for coastal areas – what are the challenges?
We will start by answering this unobvious question: what’s actually different near the coast in Ireland?
First things first – salt in the air. You don’t see it, but it settles on surfaces, including frames and fittings. In course of time, it can affect finishes and smaller elements like hinges or handles.
Then there’s the wind. Not just occasional strong gusts, but regular exposure. Windows need to stay stable, well-sealed and resistant to pressure practically 24/7.
Sand and sun cannot be forgotten either. Wind can bring along sand that scratches glass surfaces, and the high levels of UV radiation reflected from the ocean may cause the frame to become discolored or even break.
And finally – moisture. It’s the silent enemy; constant humidity means a higher risk of condensation and water getting into places it shouldn’t.
That’s why windows in coastal homes need to be much more than standard ones.

What are the best windows for coastal homes?
The main question is: which windows should you actually invest in if you live close to the sea? What material to choose, and what kind of glazing will work best?
Aluminium windows
We asked our Sales Specialist and they are unanimous – aluminum windows are the best choice for coastal areas!
Why? Because they simply handle demanding conditions better. They don’t rust, and with a proper finish, they deal well with salt exposure. It’s worth paying attention to the type of finish itself – in aluminium systems, anodised or high-quality coated surfaces provide additional protection against corrosion. These windows are also very strong – which matters more than you might think in windy areas.
Another thing people often appreciate? Slim frames and bigger glass. If you’re building or renovating a coastal home, that’s usually a big plus. Thanks to large glazing, you can achieve breathtaking views of the sea and coastline – straight from the catalogue.
We’d like to draw your attention to our bestseller: Aluminum window MB-79N SI with a thermal break. It’s really one of the greatest choices. We also recommend: Aluminum window MaxLight Modern and Aluminum window MB-86N SI.
Please note: In coastal conditions, triple glazing is absolutely a must-have. This feature provides a stable indoor temperature and reduces drafts. It also helps with issues like outside noise and prevents moisture and condensation.
uPVC windows
What if I’m not right by the coast, just a bit further inland? Do I have any other options?
That’s where uPVC comes in. It’s probably the most common option across Ireland, and not without reason. We’ve already praised this material enough in our previous articles. It doesn’t corrode, handles moisture well and doesn’t need much maintenance. On top of that, it usually offers very good insulation, which is important in Irish weather. You can count on u-values even up to 0.7 W/m²K with uPVC Fenbro windows.
Is it as strong as aluminium? Of course not. But for many homes, it’s more than enough – particularly when budget matters. Just like with aluminium, triple glazing is essential here. It does make a real difference in insulation and overall comfort.

Windows for high wind areas – which styles work best?
Now another question: does the way a window opens actually matter? Yes, in this case it does.
Casement windows
First up: casement windows. These are the ones that open on side hinges, a bit like a door. They are characterised by how tightly they close against the frame. You’ll see them everywhere in the UK and Ireland. And there’s a good reason for that. In windy areas, this really works in your favour – the stronger the wind, the tighter the seal. That means less draft and better protection from rain getting in.

Fixed windows
Fixed windows = no opening, no hinges, no weak points to be attacked by harsh weather. Sounds like a plan, doesn’t it?
As you might have guessed it right, they don’t open at all – just large panes of glass set in the frame. That’s why fixed windows tend to perform really well in exposed locations. Fewer moving parts simply mean fewer things that can go wrong. And if you’re after a view they make a lot of sense.

What windows are NOT suitable for coastal homes?
You may ask yourself: is there anything I should avoid? Any specific material?
Not everything is a hard “no”, but some options are simply more demanding. Wooden windows, for example. They can look great, but near the coast they need regular maintenance. Without it, moisture and salt can start to affect the material very quickly. Then there’s the issue of quality. Lower-end systems might look similar at first, but finishes can wear faster and seals may not hold up as well. We also recommend avoiding single glazing or double glazing of older technology.
And this is where problems can start – drafts, moisture and the need for repairs that will break the bank.

Main conclusions from this article? Aluminum windows are for sure the best solution for houses located near the coast. They are strong, exquisite, and an investment that will last for years, despite the higher price. In case your home is located a little further from the sea, more inland, then uPVC windows with high-quality triple glazing should suffice. Also, please pay attention to how the window opens, as certain designs are better suited for challenging conditions than others.

Frequently Asked Questions (FAQ)
What are the best windows for coastal areas?
It really depends on how exposed your home is. If you’re right by the sea, anodised aluminium is usually the safer option. If you’re a bit further away, good-quality uPVC windows from Fenbro will work just fine.
Does Fenbro offer windows for coastal areas?
Yes, we do. We supply both aluminium (with anodised finish) and uPVC windows that perform well in coastal conditions, and we work on projects all along the Irish coastline. If you’re not sure what to choose, just reach out – we’ll help you figure it out.
Can salt air damage my windows?
Without doubt, it can. It’s mainly because of the salt itself. Coastal air contains tiny salt particles (sodium chloride) that settle on surfaces, including window frames and fittings. Over time, this salt attracts moisture and creates a thin, damp layer. That combination (salt + moisture) can speed up corrosion.
Is strong wind dangerous for my windows?
Yes, it can be, if your windows are old, badly fitted or not well sealed. In Ireland, strong winds are a very common phenomenon. That’s why investing in high-quality Polish windows from a trusted supplier is a real deal.
What are the best windows for windy areas?
You want something strong, so aluminium is often a good call. It also helps to choose window types that seal tightly, like casement windows. That way you get less draft and better protection from the wind.
Are aluminium windows a good choice in Ireland?
Yes, especially in coastal areas. They deal with wind and moisture really well, which makes a big difference in the course of time. You’ll see them used a lot in Irish counties like Donegal, Cork or Galway for that reason.
Are special windows needed in coastal areas like Donegal?
Not really “special”, but they do need to be well chosen. The material, sealing and overall build matter more in these challenging conditions. Fenbro delivers across all of Ireland, so no matter where you are, we can help with pleasure.
