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
It's a 5-chamber system across frame and sash, built to a 70 mm installation depth with a 108–109 mm combined frame-plus-sash height. Frame heat retention is Uf 1.3 W/m²K (Uw ≤ 1.3), with two sealing circuits (8 mm inner / 7 mm outer overlap) in EPDM or TPE, and a galvanized steel insert of 1.5–2.0 mm for rigidity.
The 70 mm depth accepts infills up to 41 mm, clamped by glazing beads with a co-extruded seal. Available sealed units are:
White sash sizes top out at 1500 × 1500 mm (or 2300 mm height for balcony doors), and colored profiles should be cut by ~20% to avoid warping under solar heat. Security tops out at RC2 (ENV 1627) with suitable hardware. For passive-house Uw or large heavy-glass openings, step up to Synego or Geneo instead.
It is the value entry point. Brillant-Design 70 shares the 70 mm / 5-chamber base but reaches Uw ≤ 1.2; the 80 mm Synego (7 chambers, Uw ≤ 0.94) and 86 mm Geneo (Uw ≤ 0.85) are far warmer and pricier. Euro-Design 70 stays at 1.3 W/m²K from €320, making it the budget all-rounder below those systems.
Standard acoustic performance is around 43 dB Rw, rising to up to 45 dB with a dedicated soundproof glass unit. Tested to DIN EN 14351-1, it earns the top Class 4 air permeability (EN 12207) and Class 9A watertightness (EN 12208), so it copes well with wind-driven rain and busy urban streets.
The face uses timeless Softline contours with 15° bevels and Rehau's HDF (High Definition Finishing) coating — a smooth, glossy surface that resists dirt and wipes clean easily. Combined with a slim 108 mm sightline for a larger daylight opening and a rated lifespan beyond 40–50 years, it keeps its looks long-term.
