RE 2020

a commitment in line with the new energy regulations

RE2020 is both an energy and environmental regulation.

Unlike RT2012, RE2020 takes into account the whole life cycle of buildings and their carbon footprint. From the extraction of raw materials to deconstruction and reuse of all waste emitted by the building industry, RE2020 is moving with us towards the buildings of the present and future.


Already committed to environmentally-responsible production through its extrusion plant, Sepalumic is committed to contributing on its own scale to the implementation of these new energy regulations. Thanks to the expertise of our Project teams, we support architects and specifiers in the building industry by proposing the most appropriate solutions for the building’s exterior.

Thermal and insulating joinery ranges

We develop efficient, durable and recyclable aluminium joinery which guarantees occupant comfort and safety. Our ranges boast excellent thermal performance and meet the environmental requirements of RE2020. A strong commitment to greener and more energy-efficient construction, particularly for new residential and commercial buildings.
