ENERGY SAVING

Energy Saving From Sunrise

When you get a product fitted by Sunrise Windows you will be given a unique label.

This label will display the following information:

  • The rating level – A, B, C, etc…
  • The energy rating eg. -3kWh/(m²·y) in this example the product will lose three kilowatt hours per square metre per year.
  • The window U value eg. 1.4W/(m²·K)
  • The effective heat loss due to air penetration as L eg. 0.01 W/(m²·K)
  • The solar heat gain eg. g=0.43
  • The unique authorised user number – in our case AR 138

Simply put this will determine how well a product will perform the functions of:

  • Helping you contain and conserve heat within your building in the winter
  • Keeping out the wind
  • Resisting condensation
  • Contributing to improved sound insulation
