Welcome to SFERICS®

the building biology contact
for effective EMF shielding and data protection.

Regardless of whether it is a commercial EMC requirement for the data center or a private concern for protection against mobile phone radiation and the neighbour’s WIFI. Through our combination of building biology, measurement technology, certified materials and products, the planned shielding project is a guaranteed success.

SFERICS® emerged from PROnatur24® with the specialization in building biology and measurement technology and is more than just an online shop. For people and for companies. For office, for home office and for a healthy place to sleep. For the EMF professional as well as for the layman who wants to read up on this complex topic of shielding.

Each individual product is described in a correspondingly simple manner and yet rich in details for the EMF professional – when every single dB counts!

SFERICS® is the professional EMF contact for everyone
