The warmest and most rigid portal you'll find on the market. RAU-FIPRO material stays dimensionally stable in both heat and cold, making sashes up to 2.8 meters tall possible with no risk of sagging.
The system opens up panoramic views and step-free access to the garden. Owing to its outstanding thermal insulation, Geneo HST is well suited to pool glazing and winter gardens where condensation needs to be kept at bay.

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
On this HST (Hebe-Schiebe-Tür) system, turning the handle raises the sash onto rollers so even a very large panel glides sideways with light effort. The reinforced hardware carries a leaf load up to 400 kg, with sashes up to 3000 mm wide and 2700 mm tall (2600 mm in colour) on an 86 mm sash / 203 mm frame depth.
The sash accepts infills up to 53 mm thick, so you can specify heavy units the lift mechanism is built to carry:
RAU-FIPRO is an ultra-strong fibreglass composite that is rigid by nature, so steel reinforcement can be dropped in most cases. That removes the steel thermal bridges of conventional profiles while still holding huge dimensions stable — sashes up to 3000 mm wide and structures up to 10 m. The result is Passivhaus-grade thermals (Ud down to 0.67 W/m²K) on a portal-sized panel.
Yes. It uses a low barrier-free threshold of roughly 5–15 mm, conforming to inclusive construction standard DIN 18040. That keeps the transition between indoors and terrace nearly flush for wheelchairs, prams and trip-free walking — unusual on a slider carrying panels this heavy.
The whole door reaches Uw ≤ 0.80 W/(m²·K) (energy rating A++), with frame Uf down to 1.3 W/m²K and installed Ud as low as 0.67 W/m²K, meeting Passive House standards. Sealing is rated Class 4 air permeability (DIN EN 12207) and Class 9A watertightness (DIN EN 12208), with RC2 standard / RC3 optional burglar resistance.
At €2,200–3,200 it is the priciest Rehau slider, justified only by genuinely large, heavy glass. For lighter needs:
