An uncompromising system for prestige real estate, fully meeting strict Passivhaus requirements. Its seven-chamber, 88 mm-thick profile delivers record thermal insulation that turns the entrance door into an impenetrable shield against summer heat. The profile's structural rigidity makes it possible to design large, tall designer doors with no risk of deforming under their own weight.
Three seal circuits form an isolated "dry chamber" for the hardware, guarding the mechanisms from corrosion, dust, and sea salt. With the option to fit extra-thick armored panels and glass, the 88 Puerta system ensures maximum privacy and quiet at home. It is an investment in durability and comfort of the very highest order.

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.
Exterior entrance doors are where security, thermal performance and kerb appeal meet. This guide explains blindada vs acorazada security, aluminium vs PVC, multipoint locks, coastal weather resistance and 2026 prices in Spain. Then compare verified door specialists on Estimia.
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.
Triple glazing is the default in the Alps and Scandinavia, but in Spain it only pays off in the right climate. This guide explains what triple glazing actually does, where in Spain it makes sense (the cold interior and mountains), where it is a waste of money, and exactly what to specify — so you can compare like-for-like quotes from verified companies on Estimia.
FAQs
It is built on an 88 mm Greenline PVC profile (Passivhaus-certified) with a 7-chamber cross-section and three seal circuits, including an MD central seal. A maximum-cross-section steel core with welded corner connectors gives full torsional rigidity. Thermal protection reaches Uw ≤ 0.9 W/(m²·K), with frame value Uf up to 1.0 W/m²K and an A++ energy rating.
The deep 88 mm profile takes glazing units up to 56 mm thick, opening up infill choices a slimmer door cannot hold:
The extra build-in depth houses a full 7-chamber layout with three seal circuits, which is why the door reaches passive-house-grade Uw ≤ 0.9 W/(m²·K) and an A++ rating. The same mass and sealing drive noise reduction up to Rw 48 dB, while air leakage is certified Class 4, the highest tightness class.
Yes. It uses a highly insulated floor sill with a thermal break and a multi-stage defence against rainwater, so the entrance stays warm and dry without a high step. The door can be hung inward or outward and runs with automatic drives, and you can specify fully concealed hinges and a concealed door closer for a clean line.
It sits at the top of the door range:
At €2,300–3,100 it is the priciest non-clad door here; if you do not need passive-house values the 76 Puerta (Uw ≤ 1.0, from €1,900) covers most homes for less. It also has size limits: leaves run up to 2500 mm tall and 1250 mm wide. For an aluminium-clad exterior, the AluClip Puerta is the alternative instead.
