Photos of Origin's Aluminium Bifold Door

Threshold: Create that truly seamless link between your home and your outside space

Creating that truly seamless link between your home and outside space is all in the threshold. We recommend a weathered threshold, which can be sunk into the floor. It leaves a minimal lip but provides a protective weathertight seal.

Non-weathered options offer a level floor finish and create a seamless transition between the inside and out. Non-weathered options are largely recommended for internal usage.
