Gemini Exterm 88

Top-quality windows whose profile depth of 88 mm virtually does not impose any limitations on the thickness of glass units or size of glazing. At the same time, as an option cheaper than the flagship premium 92 and passive 92 models, it is even more popular among buyers.

Very tough and durable structure

The window frame is constructed of four layers of properly prepared timber. Each layer is glued to another in such a way that their rings are arranged alternately. This makes the construction material is highly resistant to warping, twisting and mechanical deformations.

On the outside, the frame is secured with aluminium protecting its entire surface. Thanks to that, water ans the sun do not penetrate the wood.

As a result, the frame of the whole window is stable and resistant to temperature* and humidity changes The frame also provides one of the best possible acoustic insulation.

Warm panes of glass

In this model we mount a thermal insulation unit consisting of three panes of glass. The spaces between panes of glass are filled with noble gas (argon). The unit is fitted with warm frames which improve thermal insulation properties in the area where it is joined to the window frame. As a result, the panes of glass achieve the heat transfer rate Uw of 0.5 W/m2K, and the whole window (in the reference size) of 0.8 W/m2K. With larger windows the coefficient for the whole window is also reduced.

Windows can be really big

Due to the strong, layered structure of the frame and high-end hardware, it is possible to construct a very large window surfaces. Tilt and turn window may be 1.6 m wide and up to 3 m high. Windows without the opening function (known as fixed glazing) may come in even larger sizes. And if you are looking for really large glazing, see our sliding systems offer.

Certified wood and organic varnishes

Wood used for the construction of windows is harvested in a sustainable way and is FSC certified.

We cover it with the highest quality GORI lacquers in the 4-layer technology.
Each layer performs a special function, such as closing the pores of wood, educing discolouration, ensuring proper adhesion of layers as well as mechanical ans chemical resistance.
We use water-based paints that are safe for users and the environment. With the process of automatic application, windows that look like new for years are produced in the most modern paint shop in Poland.

Various types of wood

For the production of windows we use only high-quality wood selected from European and exotic trees.

Oak, larch, spruce and pine are the European species popular among customers. The latter is also characterised by one of the best thermal insulation performance. European wood windows, often harvested locally, meet the expectations of those who are looking for products made from raw material obtained near the site of production.

Exotic species include, among others, meranti prime select, majau, sapeli, palapi and matoa. They feature a high hardness and natural resistance to atmospheric agents and are perfect for our weather conditions. They are also characterized by different graining and colours.

Elegant and modern colours

Wood can be stained in various colours and shades, at the same time preserving its visible woodgrains and authentic appearance of this noble material. When needed, it also can be painted for the desired effect of interior design.

The outer layer of aluminium can be painted in any RAL colour, may feature various textures and even „imitate” wood. This enables us to customize the window appearance to the building type and colour of the facade.

Modern and classic style

Apart from the colour, you may also choose shape of the profiles, separately for the inside and outside of the window. Below we present available variants of aluminium cladding shown in welded versions where the join of two components is completely invisible.

Various forms of wood

Our offer also includes three kinds of wood forms on the inside. The contemporary-style, simple Modern, softly rounded Smart and classic, with delicate, decorative milling Smart+. All of the above aluminium versions can be independently combined, giving 24 individual combinations to choose from!

Comfort of use

Top-class hardware is hidden under the beauty of nature. It ensures unchanging and comfortable operation of the mechanisms over the years. Thanks to it the use of windows is convenient, even when opening large surfaces. This element really affects the durability of the whole window because good hardware prevents unnecessary stress and hold the sash in the right position.

In our windows hardware by SIEGENIA and ROTO is installed. With automatic sash assembly line the installation is carried out perfectly (read more about the technology here). As standard each window is equipped with Hoppe handle with Secustik® security. On request, we use anti-theft hardware systems of RC1 and RC2 classes for break-in protection.

The windows can also be equipped with stepped tilt, electric drives, opening brakes, a ventilator can be installed or the position of the handle changed. There is also the possibility of using concealed hardware which makes sash hinges are not visible. We also offer solutions for the safety of children. When choosing the tilt first system, you may only tilt the window, and the opening function requires the use of a key. As a result, you can be calm about your children.
