Lead free, thermally superior UPVC Bi-Fold Doors

Sheerframe UPVC Bi-Fold doors deliver a contemporary style along with high-performance and reliability. Available in a range of configurations and styles to create a striking visual and functional feature to a property whilst bringing flexibility to room design.


Sheerframe Bi-Fold doors are the fashionable alternative to conventional sliding patio doors and French doors. Large, clear openings are possible removing the barrier between living accommodation and the garden.

The system is engineered using the highest quality ball-bearing raced roller mechanisms to give smooth and easy operation.

As standard it comes as inward opening and sliding at the bottom although other options such as outward opening and hung at the top are possible.

The frame sections incorporate a unique specially designed frame interlock to optimise weather performance.

Appearance and Colour Options:

Smooth surface finish in white and woodgrain foils. Doors are also available finished with any standard RAL colour.

Thermal Efficiency:

U values as low as 0.8 W/m2K can be achieved, easily beating Building Regulations’ standards.
