Combi Alu+ windows are provided with energy-saving triple glazing package, with low-emission glass and argon filled space between the panes.
The overall heat transfer coefficient for the entire window is 1,02 W/m2K.
The wood the windows are made of is subject to very thorough selection. Timber used to make the windows is carefully dried. All anatomical flaws of the wood - such as knots, burls or twisted fibres - are removed. We make our windows using pine timber.

Due to natural characteristics of timber, some colouristic differences in the wood appearance are acceptable. Moreover, due to various monitor display parameters, the presented sample can differ from actual colours.
Optionally, the windows can be equipped with one of three types of mullions:

The low emission glass decreases the temperature of the inside pane, which makes the room warm even at low outdoor temperatures.
The heat transfer coefficient for such glazing unit is Us=0,6 W/m2K
Antisol - decrease effects of sunrays, while providing splendid thermal insulation. They are recommended to be installed on southern and south-western facades of buildings.
The anti-burglar panes are used when special protection of life, health or property is required. The external pane consists of two glued panels, between which several layers of antiburglar foil are placed.
They prevent injuries in the case of breaking the pane. They are characterized by increased impact strength. They are recommended to be used in sports halls, offices, commercial facilities, public buildings.

Sound insulation is ability to muffle noise. Increased sound absorbing power means muffling of noise by at least 38 dB. Windows equipped with glazing units with increased sound insulation are recommended for buildings situated near roads, airports, railway tracks, etc.
Reflexive (mirror) panes decrease effects of sunrays, and the mirroring effect protects privacy of the inhabitants.
