Glass is popular because it is so clean and easy to maintain. The robust composite panels, which can be up to 32mm thick, consist of toughened safety glass bonded to a lightweight aerated concrete base. Airtec has several completed sites in the UK. Airtec Glass is made in Germany, where it can be cut to almost any size for your project, even up to sizes as large as 3000x1200mm. Whilst not the cheapest façade material, Airtec Glass is unrivalled in its appearance. Modern ceramics and glazed terracotta simply cannot compete with a look that is so clean and precise.
