Rehau High-Design Slide is a refined yet practical answer for situations where every centimeter of space matters. In contrast to casement windows, this system's sashes glide to the side, leaving the windowsill and the area in front of the window entirely clear for your plants, furniture, or decor.
Thanks to its multi-chamber PVC profile and support for glazing up to 24mm, the system runs considerably warmer than aluminum "sliders". That said, for heated living areas (bedrooms, children's rooms) we suggest opting for sealed systems from the Synego or Geneo families.
The system pairs Rehau's renowned, dirt-repellent HDF (High Definition Finishing) surface with dependable hardware. The sashes slide smoothly and silently, and a choice of opening layouts (2, 3, or 4 tracks) makes it possible to glaze wide openings.

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 parallel-sliding PVC system available in 2, 3 or 4 tracks, with a build-in depth of 86 mm (2-track) or 160 mm (3-track) and a 41 mm leaf depth. Hard limits per sash:
The leaf takes infill up to 24 mm thick. You can fit single glass from 4 mm or a single-chamber energy-saving unit of 20–24 mm, available clear, tinted, laminated or decorative. With the right glass it reaches up to 28–30 dB of acoustic damping — but a sealed casement is needed for thicker, higher-spec units.
It seals with a double brush seal plus a fin-seal insert running the full sash perimeter, which catches dust and softens wind but is not a rubber gasket. Its Uf is approx. 2.7 W/m²K ("semi-warm"), with an air-leakage Class 4 and watertightness Class 5A–7A. It excels at enclosing balconies and loggias, not as a primary bedroom window.
The High-Design Slide is a light-duty parallel slider (≤100 kg leaves, brush seals, Uw ≤ 1.5). Step up when you need more:
The sashes glide sideways along the track rather than swinging inward, so they claim no room as they open — ideal where a casement leaf would block furniture on a narrow balcony or loggia. The multi-chamber profile carries steel reinforcement for rigidity under wind loads, and 2/3/4-track layouts let panels stack or pass each other.
Yes — it is rated Energy B with Uw ≤ 1.5 W/(m²·K) and a frame Uf of about 2.7 W/m²K, classed as "semi-warm" for unheated zones. Its compact PVC profiles run noticeably warmer than aluminium sliders, and the HDF (High Definition Finishing) surface is smooth, easy to clean and weather-resistant.
