A high-performance glass façade must provide excellent thermal insulation, ensuring comfort and compliance with building energy regulations.

Key considerations:

• U_g-value of glazing – lower U_g-values mean better insulation.
• Comfort – prevent cold drafts and condensation inside.
• Sustainability – reduce heating and cooling demand for greener buildings.

Recommended glass types:

• Low-emissivity glass with low-e coatings to reflect interior heat back inside
• Insulating Glass Units (IGUs) with argon or krypton gas fill
• Triple glazing for maximum insulation in cold climates
• Warm-edge spacer technology to minimise heat loss at edges
