Elegant Design for Contemporary Living

Crafted from hot-rolled steel sections with Crittall’s signature slim sightlines, Innervision® internal sliding doors maximise glass area whilst maintaining structural integrity. The minimalist steel frames create an airy, open aesthetic that floods interiors with natural daylight, making them the perfect choice for open-plan living or flexible room partitioning.

Each door features welded corners and precision manufacturing to tolerances of +/- 1.5mm, ensuring a refined finish that complements both contemporary and traditional architectural styles.

Versatile Opening Configurations

Innervision® sliding doors provide ultimate design flexibility with multiple opening options to suit your interior layout. Choose from pocket door systems where doors slide discreetly into wall cavities, rebate configurations for tighter spaces, or face-mounted installations for straightforward fitting. This versatility ensures seamless integration into diverse architectural projects, from residential renovations to commercial fit-outs.

The concealed top running gear and discreet floor tracks deliver a sleek, unobtrusive finish that maintains the minimalist aesthetic. Optional soft-close damper mechanisms provide gentle, controlled closing, adding a premium touch to the user experience whilst protecting the integrity of the glass and frame.

Superior Steel Construction

Manufactured to BS 6510 W20 section standards, each Innervision® door undergoes hot-dip galvanisation to BS EN ISO 1461 followed by Duralife™ polyester powder coating. This dual-layer protection ensures exceptional durability and longevity, whilst the steel construction delivers the authentic slender profiles that define Crittall’s heritage aesthetic.

The hot-rolled steel sections provide superior strength compared to alternative materials, allowing for genuinely slim frames without compromising structural performance. Woven pile draught strips secured into jamb extrusions work alongside applied EPDM compressible seals to enhance insulation and weather resistance, whilst glazing beads are designed without horizontal ledges to prevent dust accumulation.
