Bifold doors offer a choice of opening configurations to suit any application. Choose to fold the sashes internally or externally, place the opening at the side so the sashes all fold one way, at one end, to create a single entrance door for easy access, or in the middle to give the option of a double door. All Visofold profiles feature a polyamide thermal break that enhances the thermal performance of the profile and improves the overall U-Value.
