Our CF68 Aluminium Bifold Doors come with incredible threshold technology which provides the highest performance weatherproofing even with low thresholds – as well as offering burglar resistance Class 2 for an exceptional level of safety for your customers’ homes.

Our standard threshold is just 30mm, which provides guaranteed full weatherproofing for any external bifold doors exposed to the elements.

Additional weatherproofing is also available to handle more extreme environments: the Double Weather Seal has 300Pa of water tightness with a very low threshold of just 23mm – 44mm.

Either threshold can be fitted with a choice of 3 cills to make sure the doors are suitable for any property: 150mm, 180mm and 220mm.
