Rationel sliding doors help to create a light filled energy efficient space thanks to the slim frame profile and energy efficient double glazing. The ALDUS alu-clad range has a very slim frame depth making it an ideal choice as a replacement unit for old PVC sliding doors.
Passive House Standard
Improving the energy efficiency of your window can greatly reduce your heating bills and improve the comfort of your home. Rationel windows are a great choice when looking for energy efficient windows as their alu-clad timber construction offers superb air tightness and when combined with the latest triple glazing glass can achieve very high U value.
The Rationel sliding doors come in a standard range of colours as well as the option to customise further with the option to select any RAL colour for an additional cost.
All Rationel products come with energy efficient double glazing as standard, exceeding current UK building regulations. The inner pane of the glazing unit is fitted with an invisible metal coating allowing thermal gain from the sun's rays and reflecting internal heat back into the room. Additional glazing options are also available including OBSCURE, SOLAR, SOUND, SECURE, FACADE and SAFETY.
Rationel have invested a lot of development into the security of their doors and have been tested and certified to police security standard. If you are looking for a door that meets the strictest security standards you are in safe hands with a Rationel sliding door.
