The I-tec Core.
Show-stopping performance.


Our HF410 timber/aluminium-clad window showcases precision engineering throughout the entire core. Our Austrian factory processes thin glued timber layers, a process commonly found from super stable roof beams and supports. This effective process exhibits a multitude of benefits constructing this superb, high performance window that really is the best of the best. The HF410 I-tec core layers ensure excellent load bearing properties which allow you to create larger window sizes, creating beautiful picture windows that flood your home with natural light. The combination of timber layers makes your HF410 considerably more humidity resistant, much more durable and so much stronger. This strength allows us to slim down our window sight lines and introduce more natural light to your home.


Windows with I-tec Glazing.

One of a kind.


We've taken all round glass fixing and we’ve raised it. Our Internorm I-tec glazing system delivers all out performance. Our Internorm windows have always been the best in form and function, however the team of designers behind the HF410 have taken it to another level with their process of all-round glass fixing. The process starts with the glass. Your Eclaz coated triple glazing is precision installed into the frame. The remaining gap between the glass and the window is filled with adhesive and afterwards, this glue joint is concealed beneath the decorative cover bead. This process establishes an all round fixing, with no gaps, producing a super thermally efficient and soundproof window.
