High-performance RPT profiles
We use aluminium profiles with thermal break that combine the rigidity of metal with an interior insulating polyamide barrier. This prevents the outside temperature from transferring indoors, eliminating condensation and reducing energy consumption. They are ideal for the large windows of homes around the Bay of Cádiz.
Salt-resistant lacquering
We apply Qualicoat Seaside certified lacquers that guarantee finish resistance in environments with high salt concentration. Your window maintains its original colour and texture for decades, without needing repainting or fixing chips caused by the Cádiz sea breeze.
High-performance glazing
We combine low-emissivity glass with solar control so maximum light enters without overheating your home during the Cádiz summer months. Argon gas chambers reinforce thermal and acoustic insulation, offering year-round comfort without relying on air conditioning.
Aluminium with thermal break is the professional solution for Cádiz homes that need large-format windows without sacrificing insulation. Unlike traditional aluminium, which transferred cold and heat directly, RPT profiles incorporate a polyamide barrier that interrupts thermal conduction and eliminates the condensation so common in seafront flats.
The main advantage of aluminium over PVC is its structural strength. It allows manufacturing panoramic windows, multi-metre lift-and-slide doors and glazed facades that would be impossible with plastic profiles. For homes with sea views around the Bay of Cádiz, where light and landscape take centre stage, RPT aluminium is the option that maximises glass area with minimal profiles.

What you ask us most.
What is the difference between aluminium with and without thermal break?
Aluminium without thermal break transmits cold and heat directly indoors, causing condensation and energy loss. The thermal break incorporates a polyamide barrier between the outer and inner faces of the profile that interrupts this conduction. In the Cádiz climate, with summers above 35 degrees and high humidity, this difference is essential for comfort and savings on air conditioning.
How much do aluminium windows cost in Cádiz?
An RPT aluminium tilt-and-turn window with double glazing starts at around 450 euros per installed unit. Lift-and-slide doors for large openings range between 1,500 and 3,000 euros depending on dimensions. After visiting your home, we provide a detailed quote where every item is broken down.
How long do aluminium windows last against salt air?
With Qualicoat Seaside lacquers and stainless-steel hardware, our aluminium windows maintain their function and appearance for over 40 years in a coastal environment. It is essential that the lacquer has specific coastal certification, as a conventional lacquer can deteriorate in less than ten years with the salinity of the Bay of Cádiz.
Aluminium or PVC for a home in Cádiz?
It depends on your priorities. PVC offers better thermal insulation for standard openings and is more affordable. RPT aluminium is superior for large formats, structural strength and minimalist aesthetics with slimmer profiles. For homes with large windows facing the sea, aluminium is unbeatable. For old-town flats with standard openings, PVC usually offers the best value for money.
Do aluminium windows need maintenance?
Practically none. Just clean the profiles with a damp cloth and mild soap a couple of times a year. The stainless-steel hardware needs no greasing. With Qualicoat Seaside lacquer, the finish lasts decades without repainting or restoration.
