About Gillioz SA
Founded in 1962 in Isérables in Valais, Gillioz SA is a family business for all work in wood. The company manufactures custom-made doors, windows, shutters, stairs, parquet and floors as well as furniture, built-in wardrobes, kitchens and libraries in its own joinery workshop. In timber construction it realises roof structures, extensions and enlargements, glass facades, terraces and exterior cladding, also with prefabricated timber construction elements in spruce or larch. Planning and preparation of building applications (mise à l'enquête) is also offered; in addition, Gillioz SA is a partner of Programme Bâtiments and specialises in thermal insulation. Production is carried out by handcraft in the workshop in Isérables, whose machine park has been continuously renewed since the 2000s. The company trains apprentices every year and serves customers from architecture, construction and renovation as well as private clients.
