Bertrand Windows and Doors

Why is Smoovio a great choice?

Beautiful, exceptionally tight and easy to use. This is the modern Smoovio sliding system that you can find in our offer. It's really worth taking a closer look at them. See for yourself why. 

It is worth starting with what the BERTRAND SMOOVIO system actually is. – This is a sliding window system that allows for the construction of large-sized structures – says our Premium Customer Advisor, Robert Zwara. – This system was created from scratch – both the profile and the fittings. Thanks to this procedure, the system, in addition to its functional values - all you need to do is turn the handle and the door leaf is ready to move - is characterized by excellent thermal parameters, and also has special hooks placed on the post, ensuring high tightness and increasing safety - emphasizes our Advisor.

Smoovio is an innovative, designer solution and, above all, very convenient to use. – Its design allows the threshold to be partially embedded in the floor, which translates into comfort of use – emphasizes Robert Zwara.


Sliding systems, increasingly common, are also very practical. If you have traditional windows and doors, when arranging your apartment, you should take into account the opening zone of the sash. However, in the case of sliding systems, we can use the space directly under the window. Thanks to this, we gain even more valuable free space in our interior.

But Smoovio is not only about unique design and saving space in our home. It is also exceptionally tight. In existing sliding systems, comfortable operation often went hand in hand with low tightness. This is changing, because thanks to the innovative closing mechanism in the new SMOOVIO sliding system, possible leaks have been completely eliminated. The unique properties of the new slider are the result of a synergistic combination of elements such as the new design of fittings, innovative profile geometry and well-thought-out shape of seals.

It is these seals that - to put it colloquially - "do the job". Because Precisely they are very precisely fitted, thanks to which they ensure the highest level of sealing and protect against atmospheric influences when the door is closed. Intelligent components do their job precisely while remaining invisible to the eye. Special roller systems and a unique closing mechanism ensure both smooth sliding and the above-mentioned high tightness. They are perfect both in Poland and in places where it is cold or where various atmospheric phenomena occur - e.g. sandstorms.

Importantly, thanks to the use of the highest quality materials The Smoovio sliding system is exceptionally durable and resistant to weather conditions. – It is also available in a very wide range of colors – emphasizes Robert Zwara. – Combined with modern design and smooth and light operation, it is a frequently chosen solution – says our colleague.
