Many possibilities, everything from a single source. We plan and realize your project in a wide variety of shapes and designs, adapted to your wishes and your home.

Visit our exhibition and let us inspire you! We can advise you at our premises in Krauchthal or at your home anywhere in Switzerland.

Our aim is to make your wishes come true. We achieve this thanks to our many years of experience with extensions and glazing. Do you have an idea in mind? We'll put it on paper! In addition to a detailed quotation, we also create a visualization of your project in advance.

We have already realized living space extensions, conservatories and seating area roofing/glazing with many customers. They don't see us as a supplier, but rather as a partner. For us, our customers are not interchangeable. Every person is different, every person is special - as are their requirements. And Karl Blaser AG caters to precisely these requirements.

Be it for a patio roof, the glazing of your balcony or a conservatory. You are sure to find the right product with us. We look forward to hearing from you.
