About the Manufacturer

Hoklartherm is a German based company whose motto is to build ideas out of metal and glass for your home, court and garden. For more than 20 years Hoklartherm has been developing and producing greenhouses, sun rooms, and roofing for swimming-pools, pavilions, terrace roofing, solar verandas and a lot more. Innovation and creativity is always of the utmost importance.

The company was established by Werner Hollander, a graduate in engineering, in August 1982. However, it was in 1978, when the first “thermo semicircular arch greenhouse” was erected in the garden of the Hollander family. This pioneer greenhouse was so magnificent that this design was quickly followed by many other greenhouses of this kind.

The additional design series and the continuous further development of the greenhouse range made HOKLARTHERM become the biggest manufacturer of high-quality leisure greenhouses in Germany.
