Modern airtight windows retain heat very well, but at the same time they block natural air exchange. As a result, condensation, high humidity, fogged glass and even mold may appear indoors. Window ventilation systems solve this problem by ensuring a constant supply of fresh air without opening the window.
Baltijas durvis, with more than 15 years of experience, offers reliable micro-ventilation and air inlet solutions across Latvia. Our systems maintain warmth, silence and a healthy indoor climate all year round.
