What is Loft Insulation Specialists?
Loft insulation is a layer of insulating material laid between and over the ceiling joists to slow the escape of heat through the roof. Because a large proportion of a home’s heat is lost through an uninsulated roof, upgrading loft insulation to the recommended depth is one of the most cost-effective energy improvements available. Correctly installed insulation also needs balanced ventilation to avoid trapping moisture — something we always account for as damp and ventilation specialists.
The warning signs to look for
Catching the problem early keeps repairs simpler and less costly. If you notice any of these signs, it is worth booking a specialist survey before the damage spreads.
