Wooden windows

High-class energy-efficient wooden windows (A++)

Wooden windows are a popular solution in various constructions due to their thermal insulation properties and natural aesthetic appearance. In Lithuania, as of January 1, 2021, all new buildings must comply with the A++ energy efficiency class. The A++ class indicates that these windows are particularly effective in terms of energy efficiency.

Since 2016, Doleta has been manufacturing windows that meet the requirements of the A++ class. Modern and innovative technologies, along with years of experience, allow us to produce exceptionally warm windows suitable for passive, A++ class buildings. In the production of energy-efficient windows, we use special heat-saving materials and install additional energy-saving measures that meet thermal efficiency requirements.

Doleta exclusively manufactures windows with a thin profile. The thinner the profile, the more durable the window, as it withstands more cycles, looks more aesthetic, and allows more light into the room. The highest level of window thermal insulation ensures maximum energy savings.

Unique slim window system

A unique and slim window system: the only windows in the world using this solution, characterised by an extremely thin frame and very high thermal value. We are the only ones in the world who have created a solution for aluminium clad wooden windows, the frame width of which is only 60 mm.

Windows of an exclusive design and solution, characterised by an extremely thin frame. This solution represents the latest architectural trend that fits perfectly into modern buildings. The non-standard external and internal solution of the plane merges the extremely thin window frame with the general area, thus creating a greater sense of space. This allows for more natural light to enter the room and grants it a modern touch.

Aesthetics, ecology and minimalism are modern architectural trends. Thanks to our professional team and solutions, we fulfil the non-standard visions of architects and clients. Minimalistic and modern windows with an extremely thin frame, which thanks to a non-standard solution, offer an extremely high thermal value – Uw 0.7 W(m2*K).

Wooden windows

Natural aesthetics and warmth

Our high-quality products offer individual character, stylish luxury and efficiency. More and more, people understand that their home reflects them; nowadays we get the question "How much do the timber windows cost?" far less frequently. The cost remains in the background; as those who want to buy quality wooden windows realise that the products that are cheaper are inferior and never better; mostly our clients are more interested in the excellent aesthetic appearance of our finished products that are fantastically supported by outstanding technical characteristics. Our clients are no longer just seeking a deal or an offer as people more often now realise that this type of window systems are an investment for life.

Wood is a natural and environmentally friendly material with excellent thermally insulative qualities; this ensures a constant level of humidity within a room, and provides comfort and aesthetic pleasure. We use engineered timber manufacturing technologies that not only help to expose all of the natural qualities, but also allows the wood to be created into virtually unlimited shapes that is accompanied by a vast spectrum of colours and customisable technical solutions enhancing the diversity of applications, where even the most demanding of clients can find the solutions for their needs.

Our range and selections of bespoke windows are so diverse and varied that we can offer a solution to suit anyone, with products that compliment those enhancing traditional build homes to log built houses, sauna and garden house adaptations, as well as for one contemplating a new window balcony.

We produce wooden windows that achieve, not only a subtle and non-standard design, but that can also enhance excellent features. For example, we offer solutions that can be installed in a passive house style environment, with no active heat source; where even the larger window solutions for this type ensures both high energy efficiency and surprising thermal resistance characteristics.

In 2007, we became the first of the Baltic countries window manufacturer to acquired the German Institute Certificate of Conformity for wooden window systems, for passive houses "Passive House Quality". This series of window solutions attains a thermal conductivity coefficient of Uw <= 0.8W/m2K; and corresponds to as many as 5 of our primary window systems.

Wooden windows cladded with aluminium

The modern view of the world

Wooden windows is an ideal solution for those seeking quality, aesthetics and energy efficiency.

However, in order to preserve the unique characteristics of wooden window, reduce operating costs and extend the service life, we recommend wooden windows with wrought aluminium.

We were the first in Lithuania to introduce two systems of coating the windows with aluminium from outside. This technological solution protects the wood from external atmospheric exposure, and window maintenance does not almost need any additional costs.

Today we offer to choose from over 15 different systems of wooden windows cladded aluminium.

Comfort inside and minimal maintenance outside: the window reflecting a modern view of the world.

Wooden windows with outward opening

Scandinavian functionality

Where winds are raging and there is lack of sunshine, wooden windows with outward opening are mounted.

The windows of this type are very popular in the Scandinavian, United Kingdom and Ireland countries. With classic appearance, Danish-style windows are mainly used in windy coastal areas: the wind presses the window sash to the frame, and seals it naturally.

These windows are made with a narrower frame, so more light gets into the room. In addition, after the window is opened, it covers less living space: this is very important for those living in small flats or houses.

Outward opening wooden windows are also the specific to historical Lithuanian buildings. Therefore, they remain popular today as well: during the restoration of houses included in the list of cultural heritage, or construction of new ones, replicating our architectural heritage.

Aluminium Windows

Firm and durable

Products made of aluminium profiles are characterized by an exceptional resistance to external factors, stability and durability. This is especially relevant in industrial construction as well as for exterior doors.

A variety of overall dimensions and shapes, allowing implementing even the most daring ideas of architects, fire and intrusion prevention are main advantages of aluminium products.

We use powder paints for the decor of aluminium products, so the range of colours, gloss level or the choice of texture is very wide as you can choose from the imitation of bronze to wood texture. These products are resistant to chemicals, changes in the atmosphere, and they are easy to maintain.

No less important is that the modern aluminium products are environmentally friendly due to not only good thermal insulation parameters, but also the possibility of remodelling the construction in full.

Unique windows

Exclusive design and minimalism

There is more and more minimalism in modern architecture, which gives buildings exceptional design, uniqueness and exclusivity. We adapt to the needs of our customers and we create windows, which organically merge with the façade plane, are minimalist and at the same time exude a simple aesthetic.

Unique windows are windows that stand out with their non-standard design, as well as unique structural features that merge harmoniously into the building as a whole. Natural and ecological materials are used for the production of these windows: glass, wood, aluminum.

We produce windows that not only fulfill all architectural solutions, but also have excellent durability characteristics, the highest thermal and sound insulation, wind and water (in) permeability properties.

Steel windows

Exceptionally thin lines

Modern architectural trends and innovations encourage the creation and production of windows of exceptional design. Doleta, applying the latest technologies and customer needs, implements innovative solutions – designs and manufactures steel windows.

Doleta specializes in the production of doors and windows from narrow profile stainless steel systems. The uniqueness of steel windows is thin profiles, which are characterized by lightness, but at the same time durability. The steel windows are equipped with a thermal bridge, which corresponds to the highest thermal class. Steel is a very stable and strong material, so a large area of window sashes can be obtained.

Steel profile products can be of various shapes, widths and sizes, adapted to the nuances of the customer’s design. High resistance structures can be equipped with thermal insulation, fire prevention or protection against burglary. Steel profile systems are intended for use in facilities such as office and business premises, schools, shopping centers, airports, embassies, prisons and healthcare facilities, and of course private homes.

Fire-resistant wooden windows

Windows that protect you

With increasing urban density, fire-resistant windows play an important role in the construction of new buildings and the renovation of old ones. They stop the spread of fire between adjacent buildings or individual building elements in the event of a fire.

Doleta has started producing certified fire-resistant wooden windows, which have undergone initial type testing at the Fire Research Centre Products Research Division laboratory. The company is certified for fire-resistant wooden windows in the European Union, the United Kingdom, and Japan.

Fire-resistant windows are classified according to their fire resistance class: EI15 / EI30 / EI45 / EI60. The company’s certificate shows that its wooden fire windows are of the EI60 fire-resistance class. The abbreviation EI60 means that the wooden fire-resistant window remains stable for 60 minutes during a fire and stops flames from entering the area on the opposite side of the fire.

Bulletproof wooden windows

Maximum safety

When building a private residence or a very specific workplace, we always think of safety and comfort. Bulletproof wooden windows are one specialised solution that can contribute to the security requirements of the premises.

It is important to emphasise that certain security measures should not interfere with the desired architectural style and beauty of the building. Taking into account customers’ needs, specialised bulletproof windows are manufactured by installing bulletproof glass units and combining them with special high-end wood and bulletproof steel.

The first bulletproof wooden window was produced by Doleta in 2005 and demand is growing every year. Doleta designs bulletproof windows to provide maximum protection against any threat to your safety. They are designed and manufactured using only the highest quality materials that are resistant to shocks and bullets. Testing of bulletproof wooden windows is based on certificates.
