Who is Gealan: German technology with the most modern design on the market

Gealan Fenster-Systeme GmbH is one of the leading European manufacturers of PVC profiles for windows and doors, headquartered in Thüringen (Germany) with a presence in over 70 countries. Founded in 1960, it has been manufacturing systems combining energy efficiency, durability and design for over 60 years. Its most popular systems in Spain are the GEALAN-LINEAR® — its most versatile all-rounder — and the S 8000, an economical yet high-performance system. Both work with a depth of 74 mm and are designed to accommodate glazing up to 48-50 mm (with the exclusive STV® technology). The S 8000 is certified by the Passivhaus Institut, making it a solid option for high energy efficiency projects.

Our experience with Gealan windows

Gealan has been manufacturing PVC profiles in Germany for over 60 years. Their GEALAN-LINEAR® system is the most angular and minimalist design in PVC.

The STV® technology allows glazing up to 50 mm to be installed without additional seals. Their sustainability commitment is genuine: up to 59% recycled material.

Gealan's price is more competitive than Veka or Kömmerling for similar performance.

GEALAN-LINEAR®: the minimalist all-rounder

The GEALAN-LINEAR® works with 74 mm and achieves a Uf of 1.0 W/m²K — comparable to 76 mm systems from competitors.

Available with flush sash, creating a flat facade without relief. An architectural finish very sought after.

IKD® technology improves insulation beyond standard multi-chamber geometry. With STV®, it accepts glazing up to 50 mm.

GEALAN S 8000: high performance at an optimised price

The S 8000 is certified by the Passivhaus Institut — unusual for a mid-range system.

It has passed all water tightness (class 9A), air permeability (class 4) and wind resistance (class C5) tests.

For projects where energy efficiency is needed without premium system costs, the S 8000 is a solid option.

Gealan Innovation: AluConnect and VISION XXL

IKD® Technology: factory-improved insulation

IKD® acts on the profile geometry to improve insulation structurally, not with foams.

The result is a Uf of up to 1.0 W/m²K with 74 mm — better than many 76 mm systems.

STV® Technology: glazing up to 50 mm without additional seals

STV® allows glazing up to 50 mm to be installed directly in the profile rebate.

With other manufacturers, 50 mm glazing requires special adaptations. With Gealan, it is standard.

GEALAN-acrylcolor®: surface more resistant than standard PVC

GEALAN-acrylcolor® is an acrylic layer integrated into the profile during extrusion. It cannot peel or yellow.

Available in bright whites, modern greys and metallic colours.

Our rating of Gealan as installers

4.6/5
The GEALAN-LINEAR® is the most minimalist and angular design in PVC — a window that looks like aluminium

Gealan is one of the German PVC brands that has surprised us most. Its GEALAN-LINEAR® system has such a clean angular design that our clients cannot believe it is PVC until they see it up close. The IKD® technology and the ability to install glazing up to 50mm thanks to STV® make it a technically very solid option. Up to 59% recycled material. The price is more competitive than Veka or Kömmerling.
