Preisig AG
Zürich
Tap a star to rate
Preisig AG has been active in construction since 1934 and built up its solar business as an extension of its building envelope services. The combination of roof waterproofing and PV installation suits flat-roof buildings, where the roof and the solar system get done in a single job.
Reference projects in the canton of Zurich include residential and school buildings. The company's own solar calculator on the website gives a first estimate. For complex facade or roof projects in the city of Zurich, Preisig is a reliable partner with local know-how.
