Cortizo A 84 Passivhaus represents the technological summit of the PVC profile lineup, built for those unwilling to compromise on thermal insulation. The system carries official certification from the renowned Passivhaus Institute (Germany) in the "cool temperate climate" category, making it the natural pick for passive houses and projects demanding the very highest energy savings. Under Spanish conditions this window acts as a formidable thermal barrier: it keeps 100% of the heat indoors in winter, while in the heat of summer it shuts the warmth out, yielding substantial air-conditioning savings.
The profile architecture is striking: an 84 mm installation depth, 6 separate air chambers and, crucially, three sealing circuits (the central gasket included). This layout drives heat loss down to its physical minimum. The system is engineered to hold heavy triple glazing units up to 56 mm thick. Choosing Cortizo A 84 is an investment in the future: these windows sit decades ahead of today's building standards, delivering luxury-grade quiet and climate control.

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.
A full data report on windows and doors in Spain: the PVC value chain traced through customs data (resin, profiles, finished units), where Spain buys its profiles and ships its windows, the €4.16-billion domestic sector, the swing from aluminium to PVC, and the subsidy bottleneck holding back a 20-million-home renovation backlog.
A neutral, like-for-like comparison of the PVC profile brands sold in Spain — Kömmerling, Veka, Rehau, Deceuninck, Schüco and the major Spanish systems — by chambers, Uw, reinforcement and price tier. We also explain why the company that fits the window matters at least as much as the brand on the box.
The oscilobatiente window opens two ways from a single handle: tilt inward for safe ventilation or swing fully open for cleaning. Here's how the mechanism works, how it compares with sliding and casement windows, and what it costs in Spain in 2026.
The best window for a bedroom is not the best window for a kitchen, a bathroom or a living room. This room-by-room guide explains what to prioritise in each space — acoustics and blackout for sleeping, easy-clean ventilation for cooking, privacy and moisture resistance for bathrooms, light and views for living areas, safety for children's rooms — so every window in the house earns its place.
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 an 84 mm-deep PVC system with 6 chambers across frame and sash and 3 EPDM sealing circuits (outer, central and inner). The result is a frame heat transfer of Uf 0.74 W/m²K (with thermal modules) and a whole-window value of Uw ≤ 0.66 W/(m²·K). Steel reinforcement, optionally with a thermal break, keeps the profile rigid.
The deep 84 mm frame leaves room for a sealed unit of up to 56 mm. That bay accepts a double-chamber, triple-pane build with low-emissivity coatings and an argon or krypton fill. More panes and gas-filled cavities are what drop the window to Uw ≤ 0.66 W/(m²·K); a thinner unit could not reach that figure.
The A 84 carries an official Passivhaus Institut certificate (Darmstadt) for passive buildings. Paired with its A+++ energy rating, that means the system has cleared the standard's strict heat-loss criteria, so it can be specified directly into a certified passive or zero-energy project without separate qualification of the window.
At €1,300–1,700 it is Cortizo's most expensive window, so it is overkill in a mild climate where a 70 mm system would suffice. It is also a hard opening limit:
Against the A 70 (70 mm, 5 chambers, Uw ≤ 1.1), the A 84 adds an extra chamber and a third seal to reach Uw ≤ 0.66. Even Cortizo's aluminium flagship COR 80 Industrial stops at Uw ≤ 0.8, making the A 84 the lowest-U window in the range and the only one with Passivhaus certification.
Tested figures place it at the top of the range: watertightness Class E1800, air permeability Class 4 and wind-load Class C5. The deep profile and 56 mm glazing capacity push acoustic damping to up to 48 dB (≈ 48 Rw), the highest of any Cortizo window here, enough to insulate against heavy traffic or airport noise.
