Unrivalled benefits

The Liniar ModLok™ bi-fold is the first to combine the structural benefits of an aluminium bi-fold with the thermal and colour benefits of PVCu. Available in configurations from 2 to 7 panes, opening in or out, it matches perfectly with the rest of the Liniar range of windows, doors and roofs.

Crammed with innovative features

A neat master/slave lock means the wrong door cannot be opened first, avoiding sprained locks, and folding keys avoid potential issues when keys are left in locks. The unique built-in ‘keep within lock’ faceplate gives the ModLok™ bi-fold an unparalleled appearance with no protruding hooks.

Thermally efficient

The EnergyPlus multi-chambered outer frame and sash offers maximum thermal efficiency. The Liniar ModLok™ bi-fold is also triple-glazing ready, and can achieve a U-value of 1.0 W/m²K. It even achieves a fantastic U-value of 1.3W/m²K with economical double glazed units.

Family friendly

Liniar’s low threshold is just 24mm high, offering easy access for family living. The low threshold can be combined with an optional double ramp for Part M compliance and is available with a half option for those wanting to put flooring up to the track for a seamless finish.
