Air tightness is an important factor for many reasons within a building. Poor air tightness can result in significant heat loss & transfer of external/internal sounds.
In the majority of cases, apart from Passive House construction and a hand full of developers specialising in energy efficient construction, there appears to be limited understanding within the construction industry of what air tightness actually is, how to achieve it and its importance. Air leakage can account for up to half of the energy consumed for heating purposes.
By creating a warm roof with Icynene H2 FoamLite (LD-C-50) & installing Isothane Technitherm closed cell cavity wall insulation instead of traditional insulation methods will eradicate these issues.
