Windows and doors resistant to coastal climates: How to protect your home from salt, moisture and wind?

1. PVC windows and doors – good insulation, but…

PVC windows and doors offer excellent thermal and sound insulation, do not corrode and are easy to maintain. In areas with strong UV radiation and constant humidity, however, white PVC may yellow or lose its shine over time unless UV-stabilised.

Recommendation: PVC windows and doors with a quality UV-protective layer and strong reinforced profiles suit buildings not directly exposed to the sea, such as those in the second row from the shore.

2. ALU windows and doors – durability and elegance

Aluminium windows and doors are highly resistant to corrosion, moisture and UV rays, especially with appropriate anodised or powder-coated layers. Their strength is ideal for large glazed areas increasingly common in modern coastal buildings.

 Ideal for:

• Buildings directly beside the sea
• Modern villas and apartments with panoramic views
• Facade and sliding systems

3. Wood-ALU windows and doors – natural appearance, outstanding resistance

Natural wood inside and aluminium outside provide a perfect balance of aesthetics and durability. The outer ALU layer protects wood from sea salt and UV rays while the inner layer brings warmth and luxury.

Advantages:

• Durability without frequent maintenance
• Resistance to extreme weather
• High energy efficiency

• Choose stainless steel fittings – to prevent corrosion and extend service life
• Regularly rinse exterior surfaces with water – especially in buildings directly on the coast
• Install glass with UV protection and a low-emissivity (Low-E) coating – to protect interiors from overheating and harmful rays
• Quality installation – professional fitting is crucial for preventing moisture and wind penetration

When building or renovating by the sea, choose windows and doors technically adapted to Mediterranean climate challenges. ALU and wood-ALU systems have proven the most resilient and cost-effective in the long term.
