Plastic window 40x40 cm (400x400 mm) fixed (non-opening) | TROCAL


Quality plastic windows with German profile

The 40x40 cm (400x400 mm) plastic window from the quality German Trocal profile system meets the demanding requirements for thermal insulation and thus saves heating costs and improves the thermal comfort of buildings.

Modern windows in white

The uPVC windows we offer in stock are in white. The Trocal profile has a modern straight design and has a glossy and smooth surface. The material composition of the profile meets the latest strict standards and UV stabilisers are used to guarantee the colour fastness of the windows. The new plastic frames are perfectly smooth and maintenance and washing of the new windows is quick and easy. The windows are fitted with elegant grey seals.

The windows are supplied with plastic caps (caps for external drain holes).



Soundproof windows - noise dampening

The Trocal 40x40 cm (400x400 mm) fixed plastic window also significantly dampens noise from the surroundings that would otherwise penetrate into the home. The windows are glazed with high quality double glazing from PILKINGTON with an inter-glass frame, which further improves the insulation properties and prevents dew.


Trocal profile

The Trocal profile is manufactured by the German consortium Profine Group, which represents renowned brands of plastic windows and doors such as KBE, KÖMMERLING and the TROCAL profile offered by us.

Profine Group and the best window in the world

The Profine Group was founded in 2003 by bringing together several major manufacturers under one roof and today supplies quality windows and profiles to 87 countries around the world. The Profine Group is managed directly by the majority owner and is based in North Rhine-Westphalia, Germany. A production output of approx. 450,000 tonnes of high-quality profiles per year is testimony to the stability of this manufacturer and 3,500 employees at 29 locations in 22 countries strive to achieve the company's goal: "The best window in the world!".
