It is a legal requirement for buildings to be designed to prevent the spread of fire from one structure to another and consideration must be given to this while designing and specifying building materials for use in an inverted flat roof. There has been an increased focus on fire safety in residential buildings following the 2017 Grenfell Tower fire, where combustible materials used in the cladding of the tower are believed to have contributed to the spread of fire. However, this does not mean that only non-combustible materials can be used safely in an inverted flat roof.By the end of the CPD delegates should have a greater understanding of: - How Approved Document B applies to inverted flat roofs- Broof(t4) classification and testing regime- The impact of EC Decision 2000/553/EC on testing requirements- The importance of selecting appropriate insulation material- How fire regulations apply to inverted roofs and how this impacts on specification of insulation materials.

Since 1990, Building Regulations have required ground floors to be insulated in order to save energy. This article looks at the factors that need to be considered when addressing ground floor insulation, including: construction techniques, thermal bridging, calculating U-values, and the impact of insulation on a project’s design. By the end of the CPD you should have a greater understanding of:- The core principles of flooring insulation- How to calculate U-values- Loading- The importance of correct insulation material- How to perform a more accurate U-value calculation for a ground floor

This CPD article will discuss the Water Flow Reducing Layer as central to the thermal performance of an inverted flat roof - minimising heat loss due to the rainwater cooling effect. It explains the crucial role they play and how to properly account for their presence in U-value calculations. By the end of the CPD you should have a greater understanding of: - Core principles of an inverted roof- The difference between declared lambda and design lambda- The role that a Water Flow Reducing Layer (WFRL) plays in an inverted roof- How to perform a more accurate U-value calculation for an inverted roof taking into account moisture conversion factor
