About this document
U-Value Calculation for Flat Roofs by Roben is a document available to read on EtoBox.
This document provides a thermal transmittance (U-value) calculation for a flat roof component according to BS EN ISO 6946. The calculation considers 9 inhomogeneous material layers and determines the U-value is 0.18 W/(m2K) with a thermal transfer resistance of 5.52 m2K/W. It also analyzes the component draft and calculates upper and lower limits for the thermal transfer resistance.
