Door Systems


As homeowners look to extend and refurbish their homes, many are choosing to add bi-folding or sliding doors to let in the maximum amount of light, retain heat and keep noise out. Our range of aluminium doors create vast openings in an instant, bringing alfresco living to life at the turn (or pull) of a handle. Due to the natural strength of aluminium, our aluminium doors can be made much slimmer than PVC which results in larger glass areas.

We also offer aluminium residential doors which not only enhance the appearance of any home but that also bring further security, energy efficiency and style to the property. Our aluminium residential doors are virtually indestructible whilst still maintaining slim sight lines for a sleek, modern look.

All our aluminium doors are supplied with high security locks as standard with additional security upgrades available for those that are particularly security conscious. They are all available in any RAL colour and in a number of textures and finishes. They are also marine coated and have a 25 year paint guarantee.


Windows are assessed by the British Fenestration Rating Council (BFRC) and rated using a A to G scale on the basis of their total energy efficiency where an A rated window is more efficient than a G rated window. The rating covers the frame material, the frame design, glass type and all other components that make up the window.


With energy bills on the rise, thermal efficiency remains one of the number one priorities for most homes. Loss of heat plays a major part in the usability and comfort of any living space and as a result causes high energy bills. All the Opal windows and doors are enhanced with innovative polyamide thermal barrier technology which enables all our systems to exceed the energy performance requirements of current UK Building Regulations.

  • Building control requires windows to satisfy either a U Value of 1.6 or lower or a WER of C or better.
  • Building control requires doors to satisfy either a U Value of 1.8 or lower or a WER of E or better.
