About BTA SA

We take care of everything, from design to assembly of your conservatory

If you’re looking for a reliable and reputable business for the manufacture of sunrooms, porches or patio and balcony enclosures, then you’ve come to the right place!

For the past 30 years, BTA SA has been an active player in the specialised aluminium construction market, all over French-speaking Switzerland.

We take care of everything for you from start to finish, from plan creation to final assembly, coordinating all the different on-site trades along the way.

We support our customers from the initial enquiry through to handing over the keys.

To guarantee the very best quality, we use suppliers with a solid reputation – Biossun, Cover, Glaströsch, Winter Creations, Technal and Finstral – who have been trusted partners of ours for many years.

We also create all of the aluminium and uPVC elements used to construct your conservatory in our very own workshops in Sion, Valais.

You may be an individual or an architectural firm with an interest in our products. Get in touch with us now so we can discuss your project and prepare a suitable quote.
