The external bifold doors include a thermal break to provide high thermal performance and energy efficiency. Further to this, their multi-point lock mechanisms on the main opening sashes provide assurance for top security while the doors are also secured by shoot-bolt locks on the floating mullions.
The standard rebated threshold of the aluminium doors provides improved weather resistance, whilst we also offer an option for low threshold to ensure an unimpeded access. Our doors are solely beaded from the inside preventing thieves removing your glass from the outside and ensuring your home is secure.
We offer a choice of colours (standard and non-standard), both single or dual powder coating colour options to ensure every preference is met.
