Strength, style and performance

Equally suitable for a front or rear entrance, Crystal Direct's residential doors are a refreshing alternative to timber, PVC-U or composite door designs.

They use our strong aluminium frames, with the same simple lines as our flush windows.  Doors can be fully or partially glazed, or incorporate a full height aluminium panel.  These doors are engineered for strength and security and are fitted with a multipoint locking system. 

Fully compliant with PAS24, they'll make sure any home is protected from the elements.  Effective seals keep the wind and rain outside.  Our advanced thermal break technology and high specification sealed units keep the warmth indoors, and of course, if you are choosing a glazed door, we will ensure safety glass is part of the package.

All aluminium sections are finished with a tough, durable polyester powder coat, certified to the Qualicoat standard, which surpasses European requirements. The finishes need next to no maintenance – just a quick wipe down to remove surface dirt. For more challenging environments, we can also supply special marine-grade finishes.  There’s a wide choice of stocked colours chosen to enhance all types of building materials and if you want to choose something different, it’s possible to have your windows or doors finished in any RAL colour.
