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
The lift-and-slide (HST) mechanism handles a leaf load of up to 400 kg, with a tallest leaf of 2600 mm and a widest leaf of 3000 mm. Overall unit span reaches 6500 mm, depending on whether you choose a 2-, 3- or 4-sash configuration. Because the sash rises before sliding, even the heaviest panel moves with little effort.
The 76 mm sash accepts glazing units up to 50 mm thick, suiting large-format heavy panes. Available infills include:
Yes. It uses a low aluminium threshold with a thermal break, sunk into the floor for a barrier-free transition, helping with wheelchair access and trip-free crossing. The HST design seals tightly because the sash drops onto the gaskets under its own weight, reaching airtightness Class 4 (DIN EN 12207) and watertightness Class 9A (DIN EN 12208) even in heavy rain.
Built on lead-free Greenline PVC with a 5-chamber profile, 76 mm sash / 179 mm frame depth and substantial steel inserts, it reaches a whole-system Uw of up to 1.0 W/(m²·K) in the top configuration, rated energy class A+. The two-seal system also delivers sound reduction of around 43–44 dB.
PremiDoor 76 sits in the middle of Kömmerling's sliding range:
At €1900–2700, the 400 kg HST hardware is built for medium-to-large panoramic openings. For smaller everyday terrace exits where a lighter slider suffices, PremiSlide 76 (from €1000) or entry-level PremiLine costs far less. If you want maximum thermals for the same panoramic span, step up to PremiDoor 88 instead.
