Rehau Synego Slide breaks the myth that sliding doors inevitably bring "drafts". It relies on an innovative locking mechanism: as you turn the handle, the sash doesn't merely halt—it moves perpendicular to the frame and clamps tightly against the rubber seals around its full perimeter.
With its 7-chamber profile (80mm depth) and room for thick glass units (up to 51mm), this system rivals premium casement windows in both thermal and acoustic insulation. It's the perfect pick for:
- Living rooms opening onto a terrace, where staying warm in winter and cool in summer counts;
- Houses next to busy roads (cuts up to 43 dB of sound);
- Replacing dated, awkward PSK portals that are hard to operate.

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
It is a sealed sliding system using Rehau's Smarter Sliding press-to-close action: as the sash closes it clamps to the frame around the whole perimeter for top airtightness. Each leaf carries up to 200 kg with effortless one-hand operation, and the structure reaches up to 4000 × 2600 mm on an 80 mm sash / 156 mm frame build.
The 7-chamber frame / 6-chamber sash accepts infills up to 51 mm. Options include:
It carries an A+ rating with Uw ≤ 1.0 W/(m²·K), an unbroken continuous gasket (no brush gaps) and frame Uf up to 1.3 W/m²K. Airtightness is Class 4 (EN 12207). Note it has a structural frame threshold you step over, not a flat zero sill.
It is excellent for sealed everyday terrace access, but has honest limits:
Against the budget High-Design Slide (brush seals, 24 mm glass, Uw ≤ 1.5), Synego Slide seals tighter with up to 51 mm glass and Uw ≤ 1.0. Panorama Swing (slide-and-turn, up to 100% opening) and Geneo HST (lift-and-slide, 400 kg, Uw ≤ 0.80) handle bigger or heavier walls — but Synego Slide is the airtight everyday slider in the middle.
The press-to-close clamping means the sash can't be levered like a normal window, giving burglar resistance up to Class RC2, stronger with anti-vandal laminated glass. Watertightness reaches up to Class 9A (EN 12208) and air leakage is Class 4 (EN 12207) — heavy wind-driven rain stays out.
