And Floating Lock Interior Doors — featuring a minimalist central floating lock detail for a refined, modern edge that blends seamlessly into contemporary interiors.

Both styles are available with slimline aluminium profiles, bespoke glazing options such as clear, reeded, fluted, or privacy glass, and precision-engineered hardware for a smooth, durable operation. Each door is tailored to suit your space and can be configured as a single, double, or partition system — offering flexibility for home offices, living areas, and extensions.

Are they suitable for bathrooms?

Yes — privacy or fluted glass options are ideal for bathrooms, ensuites, and dressing rooms.

Do they provide sound insulation?

Yes, especially when specified with acoustic or laminated glass options.
