Leading Thermal Performance

The Sheerline Prestige bi-fold door features the innovative Thermlock multi-chamber thermal design, which is cleverly concealed within the door’s slim frames. This technology creates insulating chambers that form an effective thermal break, offering better performance than traditional polyamide alternatives. 

This design effectively insulates homes against the unpredictable UK weather, achieving U-values of just 1.4 W/(m²K) with double glazing and an outstanding 1.0 W/(m²K) with triple glazing.

Uncompromising Security

A multi-layered security system is integrated into every Prestige bi-fold door. The system is built around a powerful 5-point locking mechanism with double deadbolts. Full-length security interlocks keep the sashes tightly together to prevent them from being forced apart.

An innovative mishandling device ensures the bifold doors lock in the correct sequence every time, giving homeowners peace of mind and providing installers with a strong, security-focused selling point.

Balanced Look

The Sheerline Prestige bi-fold doors’ refined and minimal aesthetic is the result of clever engineering. Custom-designed single rollers mean that the profile has no need for floating mullions, allowing for regular 138mm sash-to-sash sightlines. 

This detail creates the “trademark balanced look” that defines the Sheerline Prestige bi-fold door range, providing uninterrupted panoramic views that elevate any property design.

Flexible Configuration

The Prestige bi-fold door system is incredibly versatile, designed to suit any style of home. A vast range of configurations is available, from 1 to 7 panes, with flexible options for doors to split or slide entirely to one side. 

The bfolding door system can accommodate dimensions of up to 6.5m wide and 2.6m high, making it ideal for creating dramatic openings. For everyday convenience, many layouts can include a dedicated ‘traffic’ door, so you don’t need to open the entire system just to come and go.
