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.
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.
FAQs
PremiLine is a parallel-sliding system: the sashes glide along aluminium or steel track rails rather than swinging inward. A single unit can carry 2 to 4 active sashes, with steel reinforcement in both frame and sash keeping wide structures statically stable. It's built around an 80 mm frame / 54 mm sash depth in a 3-chamber profile.
Each leaf can reach up to 2300 mm tall and up to 1500 mm wide, while the total unit span extends up to 6000 mm depending on sash count and opening type. These limits make it well suited to glazing balcony and loggia openings in Spanish apartments where wall-parallel travel saves floor space.
PremiLine takes glazing units up to 28 mm thick. Available infills include:
The 3-chamber profile uses 2 seals and carries tested ratings of Class 4 air permeability (DIN EN 12207), Class 7A/8A watertightness (DIN EN 12208) and Class B2/C1 wind load (DIN EN 12210). The frame heat retention (Uf) sits around 1.6–1.8 W/m²K, making it dependable for everyday balcony and terrace use.
As a parallel-sliding system with 2 seals, PremiLine is rated for Uw ≤ 1.4 and 34 dB — fine for everyday glazing, but not the top tier for thermal or acoustic demand. For extreme noise or seafront sites, step up to PremiSlide 76 (5 chambers / 3 seals, Uw ≤ 1.1, 45 dB). For large full-height patio access, a lift-and-slide PremiDoor 76/88 is the better fit.
PremiLine is the entry-level slider: 80 mm frame, 3 chambers / 2 seals, 28 mm glazing, Uw ≤ 1.4, 34 dB. PremiSlide 76 raises this to 5 chambers / 3 seals, 50 mm glazing, Uw ≤ 1.1, 45 dB. The PremiDoor range goes further still — PremiDoor 76 at Uw ≤ 0.9 and PremiDoor 88 at Uw ≤ 0.75, 48 dB.
