The Highest Levels of Thermal Efficiency & Security

  • Thermal efficient materials such as PVC-U skins, thermally efficient glass, reinforced frames and Polyurethane foam all work together to achieve the best possible energy saving ratings.
  •  S-Glaze technology also ensures the glass cannot be prised out of the door making it impossible for potential intruders to use this method to gain entry to your home.
  • Reinforced inner frame makes them 60% stronger than a standard composite door. A Rockdoor cannot be rammed and forced open.
  • Diamond Secure 3 Star Cylinders are used on all exterior doors. With a TS007 3 star rating (the highest rating available), there's no way a burglar can force, snap or drill the lock cylinder.
