The wooden patio door of minimalist design, perfect surface finish and as never before extremely accurately cut profiles will perfectly fit in classic and modern interiors. A wooden patio door will give your home some indispensable cosiness.

These wooden terrace doors may come in fairly large dimensions without any glazing bars, and as result bring lots of light and aesthetics to the interior. This is the right choice of terrace doors, as non-opening sections may be selected and arranged according to specific preferences.

Colours can be selected from RAL and NCS palette.
The interior side can be coated with varnish of a selected shade or paint.

Glass unit

The patio door can be fit with a triple glazed unit.

Basic requirements for wooden patio doors
Safety glazing should be used for patio doors: the glazing should be laminated to protect from break-in and to avoid injuries.
At least, a tempered glass must be used to avoid injuries, when the wooden patio door equipment must be simplified.

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.

This product features very good static qualities and resistance to deformation, as it has been produced of timber made of glued prime radially-cut lumber.


All materials used for manufacturing of wooden windows and patio doors 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.
- Paint holds well to radially cut wood at the surface, since the wood is dense and moves minimally; paint wear at the corners of wooden patio door 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 and patio doors 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 and patio doors 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 patio door is durable due to a tight glazing unit that is installed into the patio door using totally moisture-tight SANITARY silicon.

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

Technological advantage

Wooden windows are produced using German WEINIG system. 
WEINIG brand is the token of technological advantage. WEINIG ranks top among wood processing industry systems as the world’s leading brand offering premium ideas and technology. 
This is the reason why UAB “Sumeda” has chosen WEINIG as its reliable partner in order to create long-term value for its customers. 
WEINIG equipment allows us to offer our customers a variety of windows and doors and be sure that they will ideally match the design, because WEINIG guarantees high standards of its products: maximum precision, uninterrupted material feed, top quality of surface treatment.


Main requirement for maintenance of wooden products: wooden parts must be treated with special wood care milk once or twice a year.

System can be braced by aluminum

Wooden window or door may be more durable.

Maximum durability of the window of door is provided by the aluminium profile that covers the window from the outside. The German aluminium profile absorbs all movements, thus eliminating any possibilities of eventual cracking. The aluminium profile also protects wood against environmental impact, yet allowing the wood to “breath” for maximum positive effect. Most other aluminium systems tend to block “breathing” ability of wood and do not protect against cracking.


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.

Glass unit is fitted into the wooden frame without resting against or any direct contact with aluminium, thus maintaining maximum thermal insulation.
Aluminium clad does not have any direct contact with glass unit and does not support it in the overall structure of the window, leaving sound insulation properties of the window or terrace door intact.

Exceptional durability

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).

Technological advantage

Gutmann Cora aluminium system for wooden windows is a special product developed in Germany.

It presents a separate aluminium system fixed to the surface of a wooden article. This system uses 1.7 mm thick aluminium with high tensile strength, smooth surface and colour. Due to special configuration of the profile, aluminium does not move or deform in the course of time.

Aluminium coating is fixed by plastic clamps that protect the wood and firmly hold aluminium while absorbing any tension and preventing the wood from cracking.

Air gaps between aluminium clad and wood allow the wood to “breath” without compromising full protection of wood against adverse atmospheric impact.

Aluminium clad is clamped in the corners by metal joints, protecting the coating against cracking.

Paint coating

Gutmann Cora aluminium clads are paint coated under special technology. Colours can be chosen from RAL or NCS palettes.

Surfaces painted by powder coating are almost maintenance-free. High quality coating technology applied on the aluminium provides seamless protection against UV radiation and significant temperature variations. Powder coating technology is cost-efficient, eco-friendly, and ensures aesthetic properties of the coated articles.


Articles with aluminium clad do not require repeated paint coating or any special care products.

Aluminium clad should be cleaned twice a year with warm water (max 25°C), small amount of neutral or low alkaline detergents can be added.

Soft non-abrasive cloth should be used during washing or cleaning.

Detergents used on the washed surfaces must be removed within one hour.
