GRP-based design solutions for the construction industry

In the construction industry, conventional materials such as steel, aluminium, PVC and wood only meet requirements for energy efficiency, durability, robustness, cost-effectiveness and low maintenance to a certain extent. By contrast, pultruded composite profiles can absorb high mechanical loads while also meeting insulation requirements.

With thermal conductivity in the range of 0.3 W/m°K, GRP pultruded profiles have low thermal conductivity and thus a good insulating effect. At the same time, the GRP material has low thermal expansion (10*10°-6/°K), making this property 6 times lower than for PVC profiles.

Fibre composite materials such as pultrusion profiles are ideal for large window, door and gateway areas that have to withstand high wind loads while also providing good insulation. The modulus of elasticity is in the range of 23 GPa. or 23,000 N/mm². However, we can also manufacture GRP profiles with significantly higher mechanical properties. Talk to us!

Our GRP components are custom-made for you. We are also able to manufacture according to your surface requirements. whether sanded, with textured paint or in a smooth finish. We use samples to demonstrate the different possibilities.

GRP profiles for energy efficiency in the constructions industry

Global climate change and the necessary decline in the dependence on fossil fuels lead directly to better insulation for all types of buildings. The energy footprint of buildings is greatly affected by its windows and doors. Conventional materials such as steel, aluminium, PVC and wood only meet requirements for energy efficiency, durability, robustness, cost-effectiveness and low maintenance to a certain extent. By contrast, pultruded composite profiles can absorb high mechanical loads while also meeting insulation requirements.

Façade elements for the Deichman Library in Oslo

The new Deichman Main Library, which opened in 2020, stands right beside the Norwegian Opera House in Oslo. Now complete, the library is a paragon of energy efficiency and low greenhouse gas emissions. We are delighted to have contributed towards the success of this project. Some of the extra-large, solid window frontage profiles on the six-storey building were manufactured using modern machinery at Techno-Composites Domine GmbH. At approx. 0.5 metres thick and featuring several hollow chambers, these façade element profiles are clearly visible on the building.

Roller shutter housing connector

We worked with a customer from the construction sector to develop a GRP connecting element that optimally connects the window frame and window blind box. This transfers the high mechanical loads exerted by wind in an optimal way. At the same time, the GRP profile improves the insulation capability of the entire system. The GRP profiles are drilled and counterbored on a large scale using a CNC machine, thus making installation significantly easier for the workmen.
