Emperor Concealed Bi-folding Doors

Emperor Concealed Hinge Bi-folding Doors

With our Emperor Concealed Aluminium Bi-folding doors there are no unsightly hinges breaking up the clean lines of the doors. When closed, the cleverly engineered patented hinges are fully concealed within the door leaf, resulting in a contemporary, clean and aesthetically pleasing bifold door. These folding sliding doors will give you over a 90% clear opening and have a uniquely designed flush-line handle, which allows for a very tight panel stack when the doors are open.


Our Emperor Concealed Bifold doors are not only thermally efficient and strong, but they are also highly secure and have passed PAS 24:2012 for enhanced security. Constructed from a low maintenance polyamide thermally broken aluminium profile, these doors will create an open, flexible, modern space for both living and working environments. Using the natural strength of aluminium they provide the maximum amount of glass and light, while minimising the amount of frame.
