Systems
Technical referenceNear-total transparency, full enjoyment of the landscape and continuous investment in R&D. That is what a Lummenn opening brings to a project.
Designed, machined and assembled in Portugal.
Lummenn was born within Sernox, an aluminium fabricator with two decades of completed projects. We do not outsource what defines us: profile design, cutting, welding and the inspection of every opening all happen under the same roof.
Bring us your project.
We reply with a feasibility study of the opening and an estimate within five working days.
