Widolux has taken over the activities of Vitrotoit SA and operates throughout French-speaking Switzerland!

With many years of experience with Velux products, I founded this company to bring you the best of my expertise in roof windows.

I am very happy to offer you a new range of products, in particular those of the Roto brand for which we provide after-sales service throughout
french-speaking Switzerland.

Widolux is also the exclusive representative for Techfoam products in Wallis. I am looking forward to offering you an innovative solution for high performance sprayed insulation.
