Wider openings.
When the brief is to open a whole wall, bi-folding doors can turn the threshold into a flexible connection between the home and garden.
Specification
before selection.
The system is only part of the answer.
Sightlines, glass, thresholds, drainage, structure, reveals and installation tolerances all affect the finished result. We coordinate those decisions before manufacture.
Product performance varies by system and configuration. RÄHMEN provides the final technical specification with the quotation rather than publishing generic headline figures as guarantees.
The building decides
the level of specification.
For this range, the final system is selected according to opening size, thermal performance, sightlines, glass, thresholds, security and installation conditions.
Essential
Proven performance for well-proportioned openings.
Premium
Greater size, reduced sightlines and enhanced options.
Bespoke
Project-engineered where the opening demands more.
