When it comes to enhancing the beauty and functionality of your living space, few design elements can match the allure of Crittall® style bifold doors.

At Colin’s Sash Windows we have years of experience with aluminium Crittall® style doors. We realised that, although very popular, not everyone can afford the original Crittall® doors made of steel. We have chosen aluminium profiles that replicate the look made by the UK’s biggest supplier – Smart Systems. The bifold door options can be cheaper than our Crittall® style French doors because they can be made higher so you don’t need a fixed top light. We offer 3 types of their bifold doors:
- Visofold 6000 which is their slimmest system with 94mm sightlines where the door sashes meet . This is the most expensive option. It has 48mm transoms that horizontally divide the doors into sections with individual sealed units. Because the profiles are so slim the maximum dimensions per leaf are 1000mm wide and 2200mm high. Price around £1000 plus VAT per leaf.
- Visofold 1000 with 134mm sightlines. Each leaf can be up to 1200mm wide and 2500mm high. They have 24mm horizontal astragal bars dividing the single sealed unit into sections. We also offer a slightly slimmer version – Visofold 1000 slim with 122mm sightlines. Price from around £630 plus VAT per leaf.

The standard hardware of our modern and aesthetically pleasing bi-folding doors go hand-in-hand with the optional accessories available.
The door leaves are fixed to stainless steel rollers for reliable and smooth operation. Sashes are hung from a floating mullion and slide on a recessed bottom roller and top guide, which allow ultra-slim profiles, smooth operation and robust security.
The doors also feature magnetic catches. These prevent the doors from hitting each other when opened, which could potentially cause damage. They also serve to hold the doors open, ensuring that they will not be caught and slammed by a sudden breeze when left open. As a result, they are a great little feature for protecting your doors from everyday wear and tear.
