Wooden windows 92

The new generation window.

Manufacturing of these windows is based exclusively on innovative technologies. The production is made on CONTUREX profiling centre, the first and only one in Lithuania, which is the newest and most advanced engineering achievement of WEINIG AG, Germany, the leader of wood processing technology.

Windows of System 92 are intended for buildings of exceptional value and and for complex solutions of window systems. System 92 means perfection of surface and construction, durability and exceptionally good thermal insulation.

System 92 means:
- very thick frame of the window
- very thick glazed unit
- superb thermal insulation parameters
- unsurpassable quality of surface finishing
- durability of the next generation
- thoroughly selected, tested and certified materials

This system of wooden windows is flexible enough to fit the most complex projects.
U = 0.83 W/m2K (with a 3-glazed GN unit)

The system was developed in cooperation with Leitz GmbH & Co. KG, Germany.

System 92 was born by combining our 17 years of experience in window manufacturing and the wooden window technology know-how of Leitz GmbH & Co. KG and their designed and tested window profiles.

A lot more aesthetics due to innovative solutions from now on!
A construction that contains hinged and fixed parts in one fame now looks much more attractive then ever. Aesthetic outlook is ensured by eliminating all additional inserts. Window parts of different height are joined very nicely.

The new generation opening mechanism

Siegenia Aubi (Germany)
The windows are equipped with the new generation SIEGENIA TITAN AF fittings.

What matters most?
1. Easy opening is more comfortable then ever
2. New generation security – three security points in the standard package
3. Solutions that improve durability

The fittings are sunken into the window frame, thus allowing for larger product dimensions that lead to higher strength. We were the first to use this fitting solution in Lithuania. SIEGENIA TITAN AF fittings feature an improve window tilt function: increased pull-in distance and improved stopping element ensures gentle and soft opening of the leaf. The new generation opening mechanism protects from draft – the windows don’t slam. The new fittings even more effectively protect against corrosion. Moreover, engineering improvements have reduced potential for errors and deviations. Even more fixing points from now on. The window became ever more secure.

All materials used for manufacturing of wooden windows are certified, tested and durable.

Durability due to innovative profile
- Our new window manufacturing equipment ensures unsurpassable manufacturing precision (timber cutting error is only 0.1mm). That allows us to ensure unmatched wood surface quality and durability.
- A completely new construction of the bottom part of the system: water boards at the bottom of the window frame are moved forward, significantly reducing cold bridge and improving protection the most vulnerable part of the wooden window against weather impact.
- Paint holds well to radially cut wood at the window surface, since the wood is dense and moves minimally; paint wear at the corners of wooden window profiles is protected by rounded profile edges.
- Our new window manufacturing equipment guarantees uninterrupted manufacturing process, eliminating manual labour and absolutely minimizing error potential. All necessary slots for installation of handles and hinges are precut exclusively by the Conturex profiling centre. Unrivalled advantage of the Conturex profiling centre is its ability to impregnate timber even in the slots for handles and hinges. Few other wooden window manufacturers can boast such timber priming technology.

Durability due to timber
Our wooden windows are durable due to properly selected timber and special water resistant glue used for joints. This glue strongly binds timber and impregnates it against permeation of humidity.

Durability due to paint
Our windows are durable due to sufficiently thick paint layer that is fit even for severe climatic conditions.
A wooden window will last very long if maintained properly.
TIP: According to Scandinavian experience, a wooden window is the most durable when painted from the outside and optionally painted or varnished from the inside. The lighter window colour is from the outside, the more durable it is.

Durability due to glazing units
The window is durable due to a tight glazing unit that is installed into the window using totally moisture-tight SANITARY silicon.

Durability due to fittings
The wooden window is durable due to strong German made fittings.


Safety guaranteed by systems solutions chosen for the specific project:

Protection against housebreaking
Wooden windows are fitted with extended safety hardware significantly limiting any possibilities of housebreaking.
Glass units are fitted inside the frames only – the glass pane cannot be taken out from the outside. In this case housebreaking is only possible by breaking the glass.
Windows can be optionally fitted with safety, laminated glass panes.

Protection against injuries
Windows can be optionally fitted with safety, tempered glass panes.

Children’s safety
Windows can be optionally fitted with locking handles to completely limit possibilities to open the windows from the inside.

Safe maintenance
Opening method of the window for safe cleaning from the inside.

Design: shapes and colours

The new window design is minimalistic due to ideal surface, smooth and highly accurate shapes, minimal number of auxiliary parts.
The window of System 92 features an innovative design, yet the wooden window frame lends a lot of cosiness and sedateness to the interior.

Traditional or unconventional: trapeze, arch etc.

Colours can be selected from RAL and NCS palette.
The interior side can be coated with varnish of a selected shade or paint.
Elegant, matt, silver-coloured hardware
Handle colours are optional.

Glazing bars
Wooden windows can be decorated with real or dummy glazing bars.

Glazing unit

Wooden window can be fit with a triple glazed unit.

What makes the glazing unit weather tight in a window?
The overall quality of glazed units is ensured by a certified manufacturer.

The windows are glazed with SPECIAL SILICON
We use neutral SANITARY silicon for installation of glazed units in all windows and patio doors without exception.
The conventional silicon is susceptible to mould, since silicon in a wooden window inevitably gets some moisture with changing seasons. Thus, we use only the sanitary silicon to eliminate the risk. What is special about this silicon? This type of silicon is mould-resistant even in zones with raised levels of humidity: baths, saunas. It protects from all micro-cracks and mould at the edges of glazed units.

Glass unit with three glass panes U = 0.5 W/m2K (52 mm)
(3 glass panes: 2 glass panes provide thermal insulation, filler – inert gas).
Light conductivity 55 %
Light reflectance 30 %
Total solar energy conductivity 37 %

Glass unit properties:
1. Thermal glazing
2. Solar energy controlling glass units
3. Sound insulating glass units. It is possible to make it up to 50 dB by fitting thicker or special laminated sound-insulating glass panes.
4. Safety glass units
5. Decorative glass units
6. Fire-resistant glass units
7. ANTIFOG glass units
8. Glass units using atmospheric effect to keep windows clean (BIOCLEAN).

Standard – 52 mm wide glass unit


The window design ensures superb thermal insulation due to:

Frame thickness
Very thick 92mm window frame and leaf.

Two rows of particularly elastic and durable gaskets.

Glazed unit
Maximal thickness – 52 mm thick glazed unit
Triple glazed, filled with inert gas
2 outer glass panels are thermally insulating
Thermal insulating parameters can be improved by using the warm TGI glazing unit frame
Window glazing is performed using special sanitary silicon that is weather resistant and doesn’t allow for micro gaps between the glazing unit and the window timber

Aluminium water board
A completely new construction of the bottom part of the window: water boards at the bottom of the window are moved forward, significantly reducing cold bridge and improving thermal insulation.
Aluminium water board at the bottom of the window stops penetration of rain and wind and protects the window from long term weather impact.


All wooden windows with opening and tilting functionality provide ventilation possibility by setting them to micro ventilation position.
Air vents can be either moulded into wooden window frame or leaf, or fitted on the top of the glass unit.

Note: it is first important to consider thermal losses prior to fitting the air vent.
