Bi-Fold Doors

The Thermashield Bi-Fold door delivers 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. Thermashield Bi-Fold doors are the fashionable alternative to conventional sliding patio doors and French doors.

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 feature slim sightlines and incorporate a unique specially designed frame interlock to optimise weather performance.
