Who are we?

We are a carpentry company, based in Sierre in Valais (Switzerland), active since 1939 in the window and carpentry sector.

Our workforce consists of 25 experienced employees and 3 apprentices in training. We manufacture and install our products with a high-quality standard. Thanks to our high-performance machinery, a "Logos" CNC machining center for windows and a CNC Weeke for carpentry, we are able to produce the most complex objects in a very short time.

A technical office with 5 experienced technicians working with 2D and 3D CAD software, with an online connection to our machining centers, is ready to take up any challenge.

We have our own assembly teams and adequate lifting equipment.

TZ is a family business, managed in the 3rd generation by Jacques Tschopp. A 2-level workshop with 3,400 m2 of production area allows us to handle large orders without any problems. In stock 360 m3 of solid wood of different types (spruce, larch, pine, oak) allows us to respond quickly to demand. A 40 m3 capacity wood dryer guarantees you dried wood that meets the requirements of our Valais climate.

TZ is a Swiss certified window manufacturer. This label is controlled by the FFF (Swiss Association of Window and Facade Manufacturers)
