bi-fold-leftThe fantastic WarmCore range of aluminium doors solves the one problem that aluminium doors have. Aluminium is a brilliant building material as it’s lightweight, has a low profile, is very strong and resists corrosion but it is a good conductor of heat and as a result can let out heat, resulting in higher heat loss than uPVC.

WarmCore’s revolutionary full-width thermal core maximises use of low conductive material and is the market leader in thermal performance being 25% more efficient than normal aluminium door systems. You get the sleek look of aluminium along with outstanding energy efficiency. WarmCore doors are available with either double or triple glazing too.

The aluminium frame is incredibly strong and secure and the doors (or sashes) can be made in many different combinations. You can specify any opening door combination you like. The doors can be stacked open to one side or split and stacked to both sides. You can even have one panel opening like a conventional door or two panels opening like French doors. Most people like to have a single opening door (a traffic door) that they use regularly as a standard door allowing them to leave the opening sashes in place until they want the entire door opened up.

Incredibly stylish and flexible, our WarmCore range features include:

  • Aluminium construction, very low maintenance, no painting, no warping, so shrinking
  • High security locking system with full Secure by Design certification
  • Option of inward and outward opening doors
  • Extremely efficient with high performance glass fitted as standard
  • Low thresholds for easy access and low profile for minimum frame size and maximum glass area
