Uncompromising security
Liniar Sliding Folding Doors have been designed with innovative security features. A unique five-point lock makes your bifold door system as secure as it is beautiful. Each lock runs the full length of the door and combines with high-strength rollers and hinges to provide optimum security for your home.
Each door system sits on a custom-made roller assembly, which sits deep within the tracks for maximum stability. Integral dog bolts also bind the doors together when closed, for added peace of mind and protection against forced entry.
Industry-leading insulation
Liniar bifold doors are purpose-built to keep your home thermally insulated. They use a radically different design approach to traditional aluminium doors.
A thermal core hidden within each door is the secret to these bifolds’ performance.
This thermal core outperforms the typical aluminium door, drastically reducing the threat of cold bridging on doors. Each bifold door is triple-sealed to ensure weather resistance and to stop draughts from getting in.
