Large glazing units under full control. Discover the new B50 and B55 internal roller blind systems

Window covers


The trend for large-scale glazing is here to stay – it provides interiors with spaciousness and a modern character. However, the comfort of using such spaces requires precise light regulation. Introducing the B50 and B55 internal cassette roller blinds, designed to take care of exactly that.


The B50 and B55 cassette blinds are solutions created specifically for large-format joinery, serving as a natural complement to our range. Where the capabilities of standard systems (such as the B5) end, our new heavyweights step in.


The B50 cassette roller blind: Functional elegance

Designed for partitions up to 2.5 m wide, the B50 cassette system is convenient in every respect. It allows for installation on the wall, ceiling, or within the window recess, whilst its compact cassette subtly blends into any interior design.


The B55 cassette roller blind: Designed for the largest formats

When it is necessary to shade glazing up to 3 metres wide, the B55 roller blind comes into play. A stable box that can act as a mounting rail, higher load-bearing capacity, and functional guides guarantee its reliability.


Why include the B50 and B55 in your offer?

Our new blinds are a tool for comprehensive project support, even after completion, when the client begins to appreciate the importance of effective light control.
