Windows have several functions in living spaces – aesthetics, natural light transmission, heat and sound insulation. In Lithuania, the most popular windows for the home are plastic, wooden or aluminium. The choice depends on the customer’s needs. Plastic windows are among the most popular because of their good price/quality ratio. Wooden windows are preferred by those who value naturalness and aesthetics. Aluminium windows are very robust and have excellent heat retention, but their appearance makes them a more popular choice for owners of modern premises, offices and factories.

1. Thermal insulation. Once you have decided on the materials for your windows, next consider their thermal insulation properties, i.e. how well the windows are able to trap heat inside the house. This is measured by Uw. The lower this coefficient, the better the windows will keep the heat in the house. High-performance windows are those with Uw less than 1.
For example, with Uw=0.73W/m2K, the windows are very good at retaining heat and meet the requirements for a passive house.

2. Double glazing We offer double or triple glazing in wood, plastic and aluminium. Windows in a warm house should be triple glazed.

3. Chambers Plastic window frames come in 5, 6, 7 chambers. The chambers are the air gaps in the frames, and the more chambers there are, the warmer the windows are for the home. Wooden windows do not have air chambers, but the thermal resistance of wood is high, so they will always be warm.

Sound insulation and security are also important features when buying windows for your home. You can consult with our professionals and we will advise you on the best products for your needs and the needs of your home.

A window in the sauna will help to ventilate the room more quickly, dry out moisture and provide more light during the day. The sauna needs to preserve heat as much as possible and only tempered glass windows should be used. We offer top-quality windows for saunas that are highly insulating and do not warp due to high temperatures, humidity or high temperature changes.

It’s best to think about a window for your sauna before you furnish the room. A window on the opposite side to the door will help to ventilate the sauna better. It is also important that it does not face nosy neighbours and is further away from the stove.

Terrace windows and sliding door systems

In Lithuania, people are increasingly appreciating light-filled houses with easy access to the terrace. As a result, terrace windows and doors are becoming an almost obligatory part of the home. Not only do they let in plenty of sunlight and warmth, but they also allow easy access to the outdoors. These windows should have an aesthetic appearance, a system that fits well and good thermal insulation. “Vekstrus patio windows and doors do just that!

Showcase windows. In a house or commercial premises with large shop windows, you want to stay longer. The high light flux makes the room feel cosy and contributes to a better mood, especially in winter, when there is less light in Lithuania. This is why houses with stained-glass windows are popular not only in Lithuania and Northern Europe, but also in many countries.

It is important that the room is ventilated when these windows are made, otherwise the air will be like a greenhouse in summer. As the windows do not open on their own, we offer them to be made and installed together with sliding or opening patio doors.

Our PVC, wooden or aluminium windows and doors are warm and airtight, so you can avoid energy loss in winter. Their colour can be matched to the overall interior or to other windows in the building.

A+ and A++ windows. Modern buildings from 2021 onwards have to be A++ according to European Union regulations, which means they have to be highly airtight, warm and very low energy consuming, and A++ buildings have to produce energy from renewable sources. Such buildings require appropriate windows with an ultra-low thermal transmittance, denoted Uw.

“Vektrus craftsmen carry out a special installation of windows suitable for A+, A++ and passive houses in the insulation layer, using special materials, guaranteeing airtightness and extremely good thermal and acoustic insulation.
