Tailored For You


Aluminium is a genuine long-life product. The aluminium profiles are designed to give strength and durability to ensure a structurally sound product that requires minimal maintenance and delivers reliable performance over a lifetime of use.


Our bi-folding doors are designed specifically around quality, endurance and aesthetics. These beautifully designed, versatile doors are suitable wherever a transformation is required. Choose between a large range of door configurations ranging from 2 panels to 8 panels with square or rounded edge profile options.


Our bi-folding doors are available in any RAL colour. We also offer a special colour range called ‘Sensations’. Sensation colours offer a unique finish to the bi-folding doors, that will make an individual statement and set the property apart from the crowd. You can also specify a dual colour.

Product Overview

  • Sliding Facility: The bi-folding doors glide on stainless steel rollers, which allows for unrestricted thoroughfares and maximum use of space and light.
  • Secured by Design: the 'Secured by Design' door is not standard and must be requested as part of the door specification.
  • Glass: Glass specification is key when affecting the doors' thermal performance as glass generally accounts for 80% of the surface area of the doors.
  • Energy Efficient: Our doors include multiple rigid rubber seals and draught excluders to ensure that you get nothing but sunlight passing through your doors.
