Energy efficient glass
The energy rating label runs from A-G with band E as the lowest level permitted for replacement windows. This generally requires a Low-E sealed unit.
Domestic extensions have to be band D or higher. This generally requires a Low-E Argon filled or warm edge spacer (Super Spacer or Enviro-TXN) sealed unit. New build can be up to band G, but only if the whole house meets other energy saving targets.
The Energy Saving Trust will allow the use of their logo for windows that achieve band C or higher. This generally requires a Low-E, Warm edge spacer and Argon filled as a minimum standard.
Pilkington Energikare
Pilkington energiKare is different from standard double glazing.
It reduces the amount of heat lost through the windows and it also allows more heat (energy) from the sun in through the window, known as solar gain.
Pilkington energiKare is made up of two special types of glass, Pilkington K Glass, low emissivity glass which stops heat escaping and Pilkington Optiwhite, a special ‘extra clear’ glass which allows more solar heat in through the windows. The use of argon gas or air filling with warm edge spacer further improves the thermal performance, and your home benefits by feeling warmer without the need to turn up the heating.
The Benefits of Pilkington energiKare:
• Improves the energy efficiency of your home.
• Reduces the amount of energy you use.
• Saves you money on your heating bills.
• Is more effective than single or standard double glazing.
• Is the only product that offers you the reassurance of Pilkington quality and enables windows to be eligible to apply as part of Energy Saving Recommended scheme.
• Pilkington energiKare is suitable for use in PVCU, timber and aluminium windows.
• Manufactured to the highest British and European quality standards.
