History

In 1984, Alois Heiler began developing frameless, easy-to-care-for shower enclosures and supplements these with his own self-manufactured line of fixtures for sliding, revolving and swinging doors made of glass.


sitec.glas GmbH was founded in 1991. This opened the opportunity for Heiler to produce their glass themselves. The state-of-the-art manufacturing facility for single pane safety glass opens the doors to new paths in the technical further development and expansion of our product range.


Heiler GmbH is formed in 2003, which is responsible for the room divider segment.

In 2004, the new manufacturing and logistics building is christened and has since then been optimizing production and logistics. Also Heiler all-glass doors and room dividers for commercial construction are prefabricated here.


In 2005, our Thailand office opens. This office caters to the Asian market with individual, custom-made glass showers "by Heiler" and "Made in Germany".
