Innovative Sheerline Index Bifold Doors
Index offers all the features and benefits Sheerline’s customers have come to expect.
A single roller eliminates the need for a dummy or floating mullion, creating slimmer more balanced sightlines. The double wheeled design differentiates Index from lower-quality alternatives. Index doors also use high quality tri-material gaskets, standard Sheerline patented corner cleats to lock in quality and strength, and standard, installer friendly pre-gasketed clip-in beads.
FEATURING THERMLOCK® TECHNOLOGY
Featuring a sleek and modern exterior, the innovative Thermlock® multi-chamber thermal design is cleverly hidden, ensuring properties remain well insulated against the challenging UK weather. These insulating chambers function as a thermal break and, when combined with high-performance glazing, deliver superior thermal performance that far exceeds that of conventional polyamide thermal breaks.
Colour Options
Hipca Gloss White 9910
Anthracite Grey Matt 7016
Jet Black 9005
DOOR HANDLES
For the finishing touches these lever handles bring a curved form to the traditional lever door handle. The door handles are available in an attractive range of colours, with fixing centres between 211mm and 122mm. They are also reversible so they are non-handed.
