Our leading products 

SMARTS Bi-Folds
SMARTS offer three designs : The Standard, The Slim Line and The Concealed Hinge to suit whatever look you are trying to achieve. The standard and slimline sightline doors are great doors providing a high specification door with a robust stainless steel running system whilst the concealed hinge door, patented by our fabricators, provides the cleanest finish on the market with all the hinges being hidden inside the frame when the doors are closed. With over 35 years experience, SMARTS have stood the test of time and continue to provide a high end yet affordable door system with clean and pleasing aesthetics.

ORIGIN Bi-Folds
ORIGIN offer two systems: The Standard and The Slimline. Both doors are fabricated to the highest of standards and incorporate unique features such as finger safe Q-Lon gaskets to the door sashes as opposed to normal rubber gaskets. The added bespoke finishing options such as colour coded gaskets and woodgrain finish options really make these doors stand out for when trying to tweak the doors to your exacting needs.
Having placed themselves in the market to deliver a very high specification door along with super fast turnarounds, ORIGIN bifold doors have quickly become one of the UK’s market leaders.
