“…Using insulation materials in buildings increases the thermal comfort of residents (Hong et al, 2009), reduces their energy bills (Webber, Gouldson and Kerr, 2015) and carbon footprint (Jenkins, 2010). Extensive modelling studies (Kerdan, Raslan and Ruyssevelt, 2016), experimental tests (Antonyová, Antony and Korjenic, 2016) and post-occupancy evaluations (Campbell et al, 2017) have been conducted to quantify the impact of various insulation materials on energy use and IEQ (thermal comfort). To understand the benefits of using PU insulation (both PUR/PIR rigid boards and SPF) for increasing thermal comfort, Figure 2 summarises the conductivity of common insulation materials with the full dataset included in Appendix A.…”
