How does loft insulation work?
Essentially, it works by trapping warm air inside your home and preventing it from rising through the roof. When properly installed, it allows moisture to pass through, preventing condensation. In a house without insulation, much of the heat escapes through various avenues—walls, floors, doors, and windows. The roof, especially through the loft, is a significant escape route for heat. This situation leaves you generating more heat than necessary, causing both increased energy bills and a higher carbon footprint. For many, understanding that loft insulation works suffices. However, if you're interested in the 'why' and 'how,' delve into the science of thermodynamics.
