6) WER simulation requirements
Installers may wish to declare up to three insulated glass unit simulations detailing components that will give them a ‘B’ or ‘A’, 'A+' or 'A*' WER. Specifications for each will be required to include details of:
• Outer pane glass
• Inner pane glass
• Mid pane glass (for triple glazed units)
• Cavity dimensions
• Cavity gas
• Spacer bar
• Primary sealant
• Secondary sealant
• Secondary sealant depth
1. Check for existing WERs on file
2. Get your IG components list
3. Are components exchangeable?
4. Get your thermal conductivity values
5. Consider Aluminium and Warm Edge
