The PUR material makes the hive three times lighter than the wooden hive and 10 times more thermally insulating (1.5 cm PUR = 15 cm fir wood). The PUR hive resists very well to the aggression of environmental factors: wind, precipitation, frost, heat; it does not absorb water, does not rot, does not crack, does not provide an environment for the development of bacteria and harmful insects. The polyurethane hive is very well accepted by the bees, and thanks to the excellent thermal insulation, in winter the bees consume less food, stay healthy, live longer, and in spring the family develops strongly. In hot weather, bees don’t have to ventilate the hive. Energy savings due to thermal insulation are used by bees for colony development and production. Literature data shows that in PUR hives production increases by about 30%.
