Over one third of home heat is lost through the ceiling, so it's most important to have effective ceiling insulation.
Whether with blanket or segment insulation, ceiling insulation needs to be well installed and thick enough for your type of house. Most houses need at least 16cm depth of insulation. To get the best benefits from your ceiling insulation, it is essential for it to be installed correctly. Poor installation – small gaps, folds or tucked-in areas, etc – can reduce your insulation's performance significantly.
