Description

The Slimline Bifold Door is 20% slimmer by design than our original Stellar bifold. At just 117mm wide, the meeting stiles create an attractive ultra-slim sightline, letting the glass take centre stage for maximum appeal.

Uniquely, it offers 4mm of adjustment – no more cutting the last sash to size. It also enables the master sash to be easily adjusted on site. Coupled with Stellar’s patented fast-fit ‘knock-in’ beads and pre-inserted gaskets, low threshold options and PAS 24 security gearing, this door is packed with features that benefit the fabricator, installer and consumer alike.

The multi-chambered polyamide thermal break technology delivers a highly thermally insulating bifold that exceeds Part L requirements with standard 28mm double glazing and achieves 0.9 W/m²K U-value.

A new integrated cill option adds even more appeal, saving 35mm of height compared with a traditional bifold cill. It also uses fewer component parts and is quicker and easier to install, especially on refurbishment projects.
