Quality windows

Dedicated research and development, a broad knowledge of traditional materials and craftsmanship, and a respect for quality design and architecture make M SORA a very special company.

M SORA windows are made exclusively from the highest quality Slovenian wood, harvested from the country’s expansive pristine forests and processed using only the most advanced and environmentally friendly technology available today.

There are a lot of windows out there on the market, many of them good. Yet no other window delivers on all of the important promises like M SORA: saving you energy and money, serving you well for years, even decades, making your home a more beautiful and functional place, naturally; and putting a smile of genuine satisfaction on your face.

M SORA applied for the European Business Awards in 2016. After judging we gained a title »National champion« in the category »The Award for Environmental & Corporate Sustainability« and are now competing in international public voting. Category includes care for environment, sustainable development, care for employees, etc.

Competition is running with public voting all over the world. One “National public champion” for each country will be selected based on number of votes and will represent Slovenia in final stage of European Business Awards competition. Voting is opened until 1st March 2017.


M SORA was awarded with Golden national award for innovations for passive window made of thermally modified spruce . Nature Optimo XLT! Innovation was presented as TED talk at Innovation day 2016.

Windows are not just a piece of furniture. They are our connection to the outside world and in most cases the only real breathing component of our apartment. Windows frame our view of the world and bring fresh wind into our home.

European project WINTHERWAX (WINdow based on THERmally modified wood with high performance WAX coating) started on 1st March 2015. The overall budget of project is 1,85 mio € and will last for 22 months.

Window M SORA Natura Optimo XLT represents an upgrade of the window M SORA Natura Optimo XL and is made of thermally modified spruce instead of the normal spruce whereas the TGI spacer is replaced by Super Spacer®. Thermal transmittance of window (Uw) using glazing with Ug value of 0.5 W/m2K is 0.66 W/m2K.

Wood windows are always a great choice. Wood windows breathe, save energy, give space a noble appearance and can even live longer than we do as far as duration is concerned. Each M SORA window goes through a complex and carefully controlled assembly process that transforms your windows into the source of a pleasant and healthy stay; thanks to these windows your space will  obtain optimal brightness and energy efficiency.


A panoramic window brings light into your home; it instantly inspires and links you with the great outdoors. Panoramic windows are also an effective means to improve the quality of life because they enhance the mood, minimize lack of space problems and provide a better use of space.
