Research output: Working paper


This document provides the technical information and guidance required for Energyflo® dynamic insulation products to be assessed within SAP Appendix Q. It provides a brief overview of two types of dynamic insulation, the analytical equations that describe their performance and the validation of these equations against empirical data from a series of Modified Hot Box Tests of the products by the National Physical Laboratory (NPL).

Documents detailing the analytical models, copies of NPL reports and the SAP Appendix Q Effective U-value calculation spreadsheet that embodies these models are bundled as part of the proposed calculation method.
