Exel Composites and the Dutch window and door manufacturer Venster Techniek have developed a composite doorsill with a Belgian blue hardstone look. “Venster Techniek turned to us to find a solution for their Flemish-speaking market to replace traditional bluestone doorsills with a more energy-efficient material”, says Mr. John Hartley, R&D Manager of Exel Composites UK.

“We saw an opportunity in expanding our product range to doorsills with a traditional Belgian blue hardstone look in order to open up new markets especially in Holland and Belgium. The product was developed in close cooperation with Exel Composites. We will shortly be able to deliver exactly the product needed for this market”, says Mr. Jurgen Rensen of Venster Techniek. 

The biggest advantage of composite doorsills over those made from traditional bluestone is the superior thermal performance. Glass fiber is an excellent insulator and thus eliminates thermal bridging, condensation and mold. Also, glass fiber profiles have high stiffness and strength, they are abrasion resistant and nearly maintenance free.
