WORLDDOMEHOUSE has developed and operating our new constant-temperature facility to replace the existing vinyl greenhouse.

Existing vinyl houses which are used by most farm houses have poor durability because it is composed only of vinyl and pipes even though constant temperature facility definitely requires consistent cultivation. Accordingly,  farmers are suffering considerable losses and damages every year like snowfall, hail, cold weather and high temperature etc. In order to solve these problems, we have been developing and distributing our exclusive Dome Greenhouse,  a new constant-temperature facility which can replace existing vinyl greenhouses. We are planning to develop to a “Plant Factory” in the future through the technical cooperation with various agricultural research institutes.

Application areas

Greenhouse / cold storage facilities / storage facilities / mushroom growers / chicken farms / duck farms / pig pens, etc.
Facilities where constant temperature is required to be maintained or damages are expected due to rapid temperature changes.
