Description

The Residential bi-fold doors have an in-frame bottom roller track that allows greater carrying capacity and facilitates the 'lay-back' option where two-panel configurations can swing back against an adjoining wall for clutter-free decks.

These are bottom-rolling and rated to 2.1m high in very high wind zones. For higher doors consider using the Metro Series or APL Architectural Series.

Key Features

For mainstream residential use
A flat-face frame, rails and stiles for a clean, contemporary look
Recommended maximum 2100mm high doors in Extra High wind zones. For larger sizes consider using the Metro Series and APL Architectural Series
The efficient bottom roller system allows optimum load capacity and increased panel width
For uncluttered decks a 'lay-back' option allows two panels to swing back against adjoining walls rather than project out at 90° (available in 2-panel, 2+1 and 2+2 configurations)
Corner bi-folds (90°) are available that do not require a corner post
Same profiles as hinged and French doors ensure continuity of style
Rebated sill track option allows flush floor levels inside and out (for sheltered locations only)
