Wooden windows with aluminium 102
The next generation window with an aluminium shield.
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.
Aluminium shielding makes usage of the wooden windows totally comfortable, since it ensures maximal durability of the windows.
The system with aluminium displays the following features:
- very thick frame of the window
- very thick glazed unit
- superb thermal insulation parameters
- unsurpassable quality of surface finishing
- durability of the new 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 3-glazed unit GN)
System 92 with aluminium shield (total frame thickness – 102mm) 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.

Solid window structure allows producing windows of custom dimensions.
Side hung and tilting
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.
Certificate QM328, issued by IFT institute at Rosenheime, Germany, on the basis of the European standards EN13126-8 and EN1191.
35 (-1;-5) dB
It is possible to optionally make it up to 50 dB with a special sound-insulating glass unit.
All materials used for manufacturing of wooden windows are certified, tested and durable.
The product is durable due to aluminium clad used in the structure.
Wooden article is durable due to Gutmann Cora aluminium system used on the outside. Aluminium fully covers and protects the wood on the outside. Wood is chained by Gutmann Cora aluminium system while leaving air gaps between aluminium and wood for the wood to “breath”. Nonetheless Gutmann Cora system provides full protection of wooden surfaces of the product against any adverse atmospheric impact (UV radiation, rain, wind, cold).
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.
Windows can be optionally fitted with locking handles to completely limit possibilities to open the windows from the inside.
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 to the interior. The external aluminium system covering the window creates an impression of sedateness and luxury.
Traditional or unconventional: trapeze, arch etc.
Aluminium can be coated with a colour from RAL and NCS palettes. Interior side can be coated optionally by varnish of a selected shade or RAL and NCS paint.
The interior side can be coated with varnish of a selected shade or paint.
Elegant, matt, silver-coloured hardware
Handle colours are optional.
Wooden windows can be decorated with real or dummy glazing bars.
Wooden window can be fit with a triple glazed unit.
What makes a glazing unit weather tight in a window?
The overall quality of glazed units is ensured by a certified manufacturer.
A glazed unit is installed into the wooden frame and does not come into direct contact with the aluminium shielding, thus retaining the best thermal insulating parameters.
Aluminium shielding has no direct contact with the glazed unit and does not support it in the wooden window construction, therefore it has no negative effect on the sound proofing characteristics of the window.

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.

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.
