Cortizo A 70 is the flagship offering from Spain's leading window manufacturer, dispelling the myth that high-quality windows have to carry a sky-high price tag. It is a finely balanced solution with a 70 mm installation depth and 5 air chambers that deliver outstanding thermal insulation, keeping interiors cool through scorching Spanish summers and snugly warm during the occasional winter chill. The clean, straight lines of the profile lend the structure a contemporary, architectural look that is prized in modern urban projects.
The key strength of this system lies in its structural rigidity. The profile is rated Class A (3 mm outer wall thickness), which ensures remarkable stiffness and a long service life. Support for glazing units up to 40 mm thick unlocks broad acoustic possibilities: you can fit specialised soundproof glass and shut out street noise entirely, be it a busy motorway or loud neighbours. Opting for the Cortizo A 70 means choosing a product that thousands of Spanish households already rely on.

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.
Traffic, terraces, airports and nightlife — Spanish streets are loud, and your windows are the weakest link. This guide explains acoustic ratings (dB and Rw), exactly what makes a window quiet, the realistic noise reduction you can expect, and precisely what to specify in a quote so you can compare verified companies on equal terms.
FAQs
The A 70 is a 70 mm, 5-chamber PVC frame-and-sash system with a frame heat transfer of Uf 1.3 W/m²K and a whole-window Uw ≤ 1.1 W/(m²·K). A twin-circuit EPDM gasket gives it Class 4 air tightness (the top grade), Class E1200 watertightness against torrential rain and a Class C5 wind-load rating.
The rebate accepts infill up to 40 mm thick. That leaves room for single, double or multifunctional (solar-control plus heat-retention) units, plus Silence acoustic laminated glass. For street noise you can run a laminated-air-laminated build or panes of mismatched thickness inside the 40 mm limit. Anything beyond 40 mm (e.g. wide triple-glazing) won't seat in this profile.
Galvanized steel reinforcement housed inside the profile resists bowing, supporting a tallest sash of up to 2400 mm for balcony doors and a widest tilt-and-turn sash of up to 1400 mm. The steel core keeps the leaf from drooping over time so seals stay tight. For openings beyond these limits you should step up to a heavier system.
The A 70 tops out at 40 mm glazing and a Uw of ≤ 1.1 W/(m²·K), so it isn't the right call for passive-house targets.
Within Cortizo's PVC casement range the A 70 (70 mm, 5 chambers, Uw ≤ 1.1) is the accessible tier, priced from €700. The A 84 Passivhaus goes deeper at 84 mm with 6 chambers and 3 seals for Uw ≤ 0.66. For sliding openings Cortizo offers the PVC C 70 and the heavy E 170 lift-and-slide — different system types, not direct casement rivals.
The compound is impact-resistant PVC reformulated to withstand intense UV exposure, and the system was engineered around the demands of the Iberian climate. Finishes also span the full Cortizo lamination range, including matte textures and lifelike wood reproductions, so a white frame keeps its tone while colour options resist fading on sun-facing facades.
