Veka Softline 82 is a premium-tier system built for passive houses and cottages with demanding energy-saving targets. Its expanded 82 mm installation width and 7-chamber frame deliver record-setting thermal insulation that holds heat in even through the harshest winters. A third, central sealing circuit splits the inner cavity into two chambers, adding an extra air barrier and dependably shielding the hardware from moisture.
As with every Veka system, Softline 82 is produced with Class "A" walls (3 mm thick), giving the structure exceptional rigidity and longevity. The deeper rebate accepts glass units up to 52 mm thick set at a generous 25 mm seating depth, which cuts the risk of edge condensation to a minimum and noticeably raises a room's acoustic insulation.
Brand
Veka — one of the oldest and largest PVC profile manufacturers in the world. The company is known for its signature Softline design with rounded edges and consistently high quality. If you're looking for reliable windows with a classic look — Veka is an excellent choice.

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.
The oscilobatiente window opens two ways from a single handle: tilt inward for safe ventilation or swing fully open for cleaning. Here's how the mechanism works, how it compares with sliding and casement windows, and what it costs in Spain in 2026.
The best window for a bedroom is not the best window for a kitchen, a bathroom or a living room. This room-by-room guide explains what to prioritise in each space — acoustics and blackout for sleeping, easy-clean ventilation for cooking, privacy and moisture resistance for bathrooms, light and views for living areas, safety for children's rooms — so every window in the house earns its place.
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
Softline 82 is a 7-chamber frame (6 in the sash) with an 82 mm build depth and three MD sealing circuits. The frame thermal value is Uf 1.0 W/m²K, and with the right glazing the whole window reaches Uw ≤ 0.80 W/(m²·K). The frame carries a closed square steel reinforcement to support heavy units.
Yes. With its 82 mm depth and Uf 1.0 W/m²K, it is one of the few PVC systems that reach Uw ≤ 0.80 W/(m²·K), the level demanded for passive house certification. This requires the correct specification — a warm glass unit and thermal inserts in the reinforcement (raising R₀ to 1.06 m²°C/W and above).
The system accepts infill from 24 mm to 52 mm, with a 25 mm glass rebate depth. That deep seating lets you fit wide triple-glazed units while guarding the edge seal against freezing. A bonded glass unit can also be set into the sash to build oversized structures.
Honestly, not every project needs it. Consider a lighter system if:
Softline 82 steps up from Softline 76 on every front: 7 chambers versus 5, an 82 mm depth versus 76 mm, and glazing up to 52 mm versus 48 mm. Thermally it moves from Uw ≤ 1.1 to ≤ 0.80 W/(m²·K), and from energy class A+ to A++. Three MD seals come as standard.
Softline 70 is the A-class workhorse — 5 chambers, 70 mm depth, glazing to 42 mm and Uw ≤ 1.3 W/(m²·K). Softline 82 nearly halves heat loss to Uw ≤ 0.80 via its 7-chamber, 82 mm build and triple sealing, jumping to class A++. Choose 82 for cold climates and energy targets; 70 for value on a sheltered facade.
