At Global Windows & Doors we believe that everyone has to make an effort to keep the environment clean and stop pollution.



This is the reason we have applied a green method of manufacturing in our company.


From the led free Upvc and Aluminium produced with polyamide, to keeping the waste at minimum and recycle all the scrap material.




And besides keeping an environmentally friendly behaviour in our production, our products will help you to save on fuel consumption, keeping your home warm with less heating and consequently less emission of CO2.

Window Energy Ratings (WERs)

Window Energy ratings tell you how energy-efficient your windows are.  The rating system is based on a scale of A-G, with A-rated windows being the most energy-efficient.



The Window Energy rating assesses the whole window energy performance and covers the frame material, the frame design, the glass type and all the other components that make up the window. The rating is carried out by computer simulation and gives a single number that can be used to compare the energy performance of a window simply and quickly.


Window Energy Ratings (WERs):




  • allow consumers to rapidly compare the energy efficiency of competing products


  • allow specifiers to select windows based on a validated performance figure.


  • allow legislators and others to ensure that fitted windows meet the legal requirements.


  • allow energy agencies to direct support to energy efficient products.


  • provide a method to link thermal window performance to other thermal assessment systems.
