Alpsteg Fenster AG (Niederlenz)

A PIONEER IN THE INDUSTRY REINVENTS ITSELF When Alpsteg Fenster AG was founded, it was a carpenter's workshop in Dürrenäsch. At that time, we were one of the first manufacturers in Switzerland to start producing vinyl windows. Thus, we are considered pioneers in the industry.

But we did not want to rest on our laurels and we expanded our product portfolio. Today we focus on our certified wood and wood-aluminum products in all shapes and colors. Our trade products vinyl and vinyl-aluminum windows, house entrance doors and shading elements perfectly complete our product range. Our after-sales service additionally ensures that existing products can reach their maximum service life. For us, a smooth project execution is decisive for our good service to you.

We want our customers to feel that high quality products and good customer relations are not incompatible contradictions, but make us a modern and service-oriented company that knows how to combine opposites:

Traditional craftsmanship and current, technical know-how.

Comfortable living space and environmentally friendly exteriors

Natural products and modern design

Maximum light transmission and energy efficiency

Light and shade

Complex installation situations and fast processes

Extensive customer consulting and efficient approach

Heat and cold

Because we manage to unite these opposites, our products are the perfect links of your exterior and interior. We design the right product for your individual situation.

But not only our products are therefore on a very high level compared to the rest of the industry, but also our services. Because we do not see the contradictions, but the challenge to work out a solution for you.
