  • ‘Tilt and turn’ windows (great for easy cleaning from the inside)
  • Fully reversible windows
For doors choose from:
  • French doors – the popular alternative to sliding patio doors
  • Multi-fold doors – open up your kitchen or living area to the outside world. Also perfect for indoor open-plan living
  • ‘Tilt and slide’ patio doors
  • Stable doors – particularly suited to older style properties
  • Residential front doors
  • Composite doors
  • Porches and conservatories (window and door elements)


With the rising cost of fuel, not to mention reducing your carbon footprint, the issue of energy efficiency is an important factor to consider when improving your property. All of the uPVC window systems manufactured by REHAU have very good thermal insulation properties which can significantly reduce heating bills. By retaining heat for longer within your property, heating times can be cut - reducing your carbon emissions by burning less fuel.
The measure for thermal insulation is given by the U-value of a window or door. The U-value measures the heat loss, hence the lower the U-value the better the thermal insulation.
Another measure of window performance is the Window Energy Rating (WER) rating which also involves the solar gain of the glass and is measured from A-G, with A being better than B etc., WER ratings A-G are similar to those used on household appliances like fridges, dishwashers and washing machines.
However, energy efficiency is not only a personal choice but also forms an integral part of the Building Regulations and PART L – the Conservation of Fuel and Power concerns itself with reducing CO2 emissions.
Changes in the regulations in October 2010 mean that windows must now have a U value of 1.6W/m2K to comply or a WER rating of of ‘C’ and all REHAU uPVC windows can easily achieve these minimum values for compliance using either method
 
All REHAU window systems can easily achieve a U value of 1.6W/m2K and can go as low as 0.8W/m2K as well as achieving 'A' ratings when used in combination with the appropriate glazing unit.
Choosing uPVC windows with the correct thermal performance and requirements for your property can be confusing - talk to your local REHAU Authorised Partner and they will give you advice and explain your options.
