Cortizo COR Vision PLUS is a system that stretches the limits of the possible. Where the standard Vision series wins admiration for its slimness, the PLUS version is built to amaze through sheer scale. It is engineered specifically to bridge enormous openings: sashes can reach 4 metres in height, turning the facade into an uninterrupted glass screen. The central interlock shows just 25 mm of visible width, trifling for a structure able to bear glass weighing up to 700 kg.
The PLUS version's chief technological edge over the standard model is its capacity for ultra-wide glazing units up to 54 mm thick. This changes the game: you can now fit a full triple-glazed unit (4 panes) or the most robust armoured laminated glass into a minimalist sliding system. With it you gain not only the breathtaking design of a "glass house" but also Passive House-level thermal insulation, beyond the reach of thinner alternatives.

PVC and aluminium are the two frames you will be quoted for almost every window in Spain, and the right answer changes from Valencia to Vigo. This guide compares them head-to-head on insulation, price per m², coastal durability, sizes, colours and noise, then gives a clear verdict by scenario and region.
Aluminium is Spain's home-team window material — and the customs data shows why. Spain net-exports roughly $1.2 billion of aluminium extrusions and finished windows a year, shipping to France, the UK and Latin America, led by Galician giants like Cortizo. A full data report on the aluminium value chain, who makes it, the thermal-break problem, and where PVC is eating in.
Corredera, lift-and-slide, folding or minimalist — Spain's terrace doors come in very different forms, and the wrong choice means draughts, trip hazards or a door you can barely move. This guide walks through the types, thermal performance, thresholds, security and realistic 2026 prices so you can compare quotes with confidence.
Floor-to-ceiling glass and near-frameless sliding walls turn Spanish living rooms into light-filled spaces with uninterrupted views. But large-format glazing brings real questions about solar heat, structure, security and cost. Here's how panoramic systems work and how to specify them well in Spain's climate.
Frameless glass curtains, framed enclosures, sliding and folding glass, thermal vs non-thermal systems — this guide explains how to close a terrace in Spain, what it costs per m², and the community-of-owners rules that catch buyers out. Compare verified enclosure specialists on Estimia.
Triple glazing is the default in the Alps and Scandinavia, but in Spain it only pays off in the right climate. This guide explains what triple glazing actually does, where in Spain it makes sense (the cold interior and mountains), where it is a waste of money, and exactly what to specify — so you can compare like-for-like quotes from verified companies on Estimia.
FAQs
This is a minimalist slider built for oversized formats. Each sash takes a width up to 4000 mm and a height up to 4000 mm, covering up to 14 m² of glazing per sash. The frame depth is 180 mm (three tracks or more) on a 57 mm sash, with the central interlock exposed at just 25 mm.
Sash mass runs up to 400 kg by hand and up to 700 kg motorised, riding on Cortizo's patented stainless-steel bearings built into the frame. An optional concealed motor adds fully automated opening, so even the largest panels stay easy to operate.
Infill reaches up to 54 mm, enough for serious glass packages:
Tested performance is high across the board: watertightness Class 7A / 9A, air tightness Class 4 and wind load rating Class C5. Sealing on a reinforced thermal break with polyamide inserts up to 34 mm wide keeps it airtight enough for an A++ energy rating.
If your spans are modest, standard COR Vision is the lighter, cheaper choice: a 116 mm frame against 180 mm here, glazing up to 30 mm against 54 mm, and roughly €950–1250 against €1200–1600 per m². PLUS only earns its premium on colossal, heavy sashes.
It is the thermal and structural flagship of the slider range:
