Living Near the Sea Brings Specific Challenges for Your Windows
- Marine Environments Accelerate the Corrosion of Standard Window Hardware
- Salt in the Air Reduces the Durability of Non-Protected Materials
- Strong Solar Exposure Increases the Energy Consumption of the Home
Why the Maritime PVC Window Line Is Different?

Salt-Resistant and UV-Protected uPVC Window Profiles
Our high-performance uPVC profiles are designed for coastal environments, helping protect your home against strong sun, salty air and humidity. They maintain thermal efficiency, structural stability and visual appeal over time, making them ideal for homes in the Algarve and other seaside locations.
Specialised Installation for the Algarve and Coastal Areas
We provide expert installation of uPVC windows and doors for homes located near the sea, with solutions tailored to the specific challenges of coastal climates. Our systems are designed to perform well in environments exposed to salt air, humidity and intense sun, making them an excellent choice for properties in the Algarve and across Portugal’s coastline.
Our services are available in the main Portuguese coastal regions, including Algarve, Costa Vicentina, Setúbal and Arrábida, Cascais and Estoril, Costa da Caparica, Figueira da Foz, Aveiro, Porto Coastline and Viana do Castelo.
Winkhaus Tricoat Hardware – Superior Protection for Coastal Environments
Windows are only as secure and durable as the hardware that supports them. At Caixilho PVC, our projects are equipped with Winkhaus hardware with Tricoat coating, an advanced anti-corrosion technology designed to withstand the most demanding environments.
The Tricoat treatment creates a highly resistant protective barrier against humidity, salt air and oxidation, making it particularly suitable for homes located near the sea and in coastal regions, where salt exposure accelerates the deterioration of conventional hardware.
