RIB-ROOF - Zambelli GmbH & Co. KG

ECOLOGICAL AND ECONOMICAL CONSTRUCTION AND RENOVATION
ACT RESPONSIBLY
EnEV 2009 German Energy Saving Ordinance:
Compliance without requiring additional measures
Energy reduction measures put high demands on
new buildings and renovation of older structures.
While energy-reducing measures are required
by several of the metal roofi ng systems that
are currently available on the market in order to
fulfi ll legal requirements, RIB-ROOF metal roofi ng
systems need no further adjustment. A RIB-ROOF
surface has optimal values concerning thermal
Technology and progress in harmony with nature
This has always been our goal for supply and
disposal which is why our products not only
always use state-of-the-art technology, but are
integrated with quality and our own environmental
management system. We are continually
developing our manufacturing technology further
in order to achieve a longer life for our products
along with optimal energy recovery, therefore
transmittance, without any further complicated
additional measures such the installation of
thermoclips serving as thermal bridges, as recently
shown by studies from the “Forschungsinstitute für
Wärmeschutz e.V.”.
Buildings with RIB-ROOF metal roofi ng system
are good for both the environment and your bank
account.
