What is the maximum U-value for external roofs?

The maximum U-value for external roofs is crucial in energy efficiency and thermal performance standards. It measures how effectively a building element retains heat, with lower values indicating better insulation properties. The correct U-value of 0.31 W/m²·K aligns with the intention of Estidama, which aims to promote sustainable building practices in the UAE.

This value ensures that roofs are sufficiently insulated to minimize heat loss, contributing to a reduced energy demand for cooling, which is especially important in the hot climate of the region. A U-value of 0.31 W/m²·K signifies a balance between construction feasibility and energy efficiency requirements, supporting the overall goals of the Estidama program to enhance sustainability and promote environmental responsibility in building design.
