Mould and Loft Insulation Cornwall
Kernow Insulation – Creating Healthier, Energy-Efficient Homes
Loft insulation plays a key role in improving energy efficiency, but when it’s installed without proper ventilation or moisture control, it can lead to condensation and mould growth. Across Cornwall, many properties suffer from mouldy loft spaces, damp insulation, and poor air circulation — issues that can damage timber structures and affect indoor air quality.
Kernow Insulation specialises in mould treatment, loft insulation replacement, and ventilation upgrades, ensuring your home remains warm, dry, and healthy.
The Problem – When Insulation and Moisture Don’t Mix
In Cornwall’s damp coastal climate, lofts often experience condensation, particularly in winter. When insulation blocks airflow or traps moisture against cold surfaces, mould can develop on timbers, rafters, and plasterboard.
Common causes include:
-
Poor or missing ventilation (eaves or ridge vents).
-
Non-breathable spray foam or over-packed insulation.
-
Roof leaks or high indoor humidity.
-
Blocked trickle vents or extractor fans.
Left untreated, this can lead to timber decay, reduced insulation performance, and unhealthy indoor environments.
