The advantage of the Invisa system

It is assembly without screwing or any interference with the window frame. The side guide rails on which the slats lower are immersed in a pre-prepared groove in the plate. Also, the mask or box of the venetian blind is plaster embedded into the facade. Thus, the system of venetian blinds in the facility, when the slats are rised, is invisible.

Moving towards energy efficiency

With the development of Invisa, we have taken a step forward in increasing energy efficiency, as the system provides us with an optimal solution for heat losses.

Discover different forms of slats

You can choose between different forms of slats that not only fulfil their functional role, but also complement the appearance of your room. There are four different forms of slats available, which differ in shape and functionality.

C slat

C80 slats are shaped in the letter C, which provide the blinds with strength and stability. Their cleaning is simple, and the water drains quickly and efficiently.

T slat

T80 slats give a slightly more robust impression with distinct and clear lines. Their advantage is that the closed venetian blinds package is lower.

S-delux slat

S Delux 90 slats are the most technologically advanced slats. At the bottom edge, they are equipped with a rubber seal to better darken the room.

Z slat

Z 90 slats with rubber seal on the lower edge offer optimal darkening and are among the most modern forms of slats.

External venetian blinds colours

Create a carefree environment with insect screens

Protect your home from annoying insects and create a relaxed and carefree atmosphere with innovative insect screens. Like the guide rails of venetian blinds, the insect screen guide rails are plaster embedded, and the insect screen box is discreetly hidden in the mask of the venetian blind. The mesh consists of UV-resistant glass fibres, which prevents it from stretching and shrinking. Insect screens are custom-made and available for windows and doors of different sizes.

Corner joint solution

The steel cable, a thin but extremely durable steel material, not only solves the aesthetic dilemma, but also provides strength and stability to the venetian blinds. The advantage of the steel cable stands out even more if windows without visible frames are glazed, as they do not obscure the view to the surroundings.

"Venetian blinds offer much more than just light regulation"

Invisa venetian blinds are unique as all their components, including the box and guide rails, are installed under the facade.

The Invisa system allows installation without screwing into the window frame, as the guide rails are immersed in a pre-prepared groove in the panel.

Lowered external venetian blinds prevent the glass from heating up in the summer, which reduces direct heat entry into the room. In winter, however, they act as an additional thermal insulator, which can save you a few euros for heating.

By adjusting the angle of the slats, you can limit the view into the room, while allowing natural light to penetrate the interior of the room.

Fully lowered venetian blinds act as an effective protection against possible burglaries. It is very important to deter most potential villains before they even try to break in.

They add aesthetic value to the facility and adapt to different window shapes.

Povpraševanje

Invisa venetian blinds are distinguished from other types of external venetian blinds mainly by their fulfilled appearance. The main feature of Invisa venetian blinds is that both the mask and the side guide rails are plaster embedded, which means that the elements of the venetian blind are maximally hidden in the facade. This discreet integration into the architecture of the facility improves the appearance of the facility.

The Invisa system is an ideal choice primarily for new constructions, but also for older buildings that are in the process of renovation, with the facade also being renovated. For the Invisa system, it is essential that the elements of the venetian blind are plaster embedded, which is only feasible if the facade is not yet completed.

In cases where there are several windows on the wall in succession and the shading is solved with an assembly of venetian blinds, an Invisa system with plaster embedded guide rails is installed on the far sides of the venetian blinds, while a steel cable or classic guide rails are used for the central venetian blinds.

Yes, Invisa venetian blinds are custom-made, which means that they are suitable for both standard windows and irregular windows, of different dimensions.

Yes, it is possible to integrate the insect screen into the Invisa Venetian blind system. The insect screen is discreetly built into the Invisa venetian blind mask, whereby the side guide rails, as with the venetian blinds themselves, are plaster embedded into the facade.
