Ventilation

Why Roof Space Ventilation Matters

Prevents condensation – Proper airflow helps remove excess moisture, reducing the risk of damp, mould, and timber rot.
Improves insulation performance – Good ventilation prevents moisture build-up, which can reduce the effectiveness of loft insulation.
Prolongs roof lifespan – By reducing trapped heat and humidity, ventilation helps protect roofing materials and timbers from deterioration.
Regulates temperature – Allows hot air to escape in summer and reduces the risk of ice dams forming in winter.
Meets building regulations – Adequate roof ventilation is a requirement for most homes to ensure a healthy living environment.
Protects indoor air quality – Prevents musty smells and airborne mould spores from entering the home.

Ventilation with insulation

The Relationship Between Ventilation and Insulation

Ventilation and insulation work hand-in-hand to keep your home energy-efficient and healthy. Insulation slows down heat loss, keeping your home warmer in winter and cooler in summer. However, without proper ventilation, moisture can become trapped in the roof space. Over time, this condensation can reduce the effectiveness of insulation, cause it to clump or compress, and lead to mould growth and timber decay.

By ensuring your loft has the right balance of insulation and ventilation, you protect your home from damp, maintain insulation performance, and create a more comfortable living environment. At Eco Insulation Cornwall, we make sure every installation includes a check on ventilation so you get the best results for years to come.
