Welcome to JANSSENS NV.

Choosing a greenhouse or a conservatory requires some serious thought.


A good conservatory  is a sure guarantee for a lifetime of living enjoyment and provides a lasting added value to your house.
Modern sun rooms are perfect illustrations of creative and technical ingenuity.
The construction side is best left to specialists who are able to take into account all the consequences – technical, financial and practical – and thus avoid any nasty surprises.
JANSSENS NV gives sound advice. More than 57 years of experience and know-how guarantee the highest quality work. You can also choose an all-in concept that can be completely tailor-made down to the smallest detail. Our very own Ancona conservatory system allows extensive design and material choices. Whether you choose a classic or modern design, a Victorian model or a veranda that is fully integrated in the house, Janssens nv guarantees the very best thermal and construction properties. Time and again, our people come up with surprising and ingenious designs that are entirely in keeping with your house and wishes.
