Glazings

Insulated glazing units (IGUs) are a fundamental component of the thermal performance of the transparent building envelope. Their two key parameters, the Ug-value (thermal transmittance) and the g-value (solar factor), must be carefully balanced depending on the climate zone. A low Ug-value reduces heat losses in winter, while an appropriate g-value allows beneficial solar gains and limits overheating in summer. The correct selection of glazing optimises the building’s energy balance, improves indoor comfort and supports compliance with Passive House requirements.
