Thermal Insulation

This document provides the framework that enables organizations to develop studies / papers on the environmental performance of wall coating products, through the Life Cycle Assessment (LCA) and also to report such performance through Type III Environmental Product Declarations (EPD).

The product category for “insulation” includes different types of products designed to reduce heat transfer between buildings and other construction works and outer space, or spaces between these buildings. A product can be included in this category if they are shown the respective technical characteristics necessary for the performance described above (in document in accordance with national law). The thermal insulation products are materials with a lower thermal conductivity to 0.065 (W / m.◦C) and superior thermal resistance to 0,30 (m2.◦C / W), according to the national legislation applicable to the thermal behavior buildings. However, other materials that do not have these characteristics (ex .: light beads in bulk or lightweight concrete), can ensure the function of heat insulation of buildings and other construction works and be so included in this product category [1] .

[1] According to LNEC publication "ITE50 - heat transfer coefficients of elements of the building envelope"

An EPD performed according to this document shall communicate reliable and verifiable PCR information about the environmental performance of floor coatings. After the development of an EPD, the organization shall forward the process to a certification body recognized by the DAPHabitat System for validation of the reported information.
