Building Regulations Part F covers a topic that has been relatively overlooked in our home's energy efficiency make-up: ventilation. Up until very recently, we all concentrated on insulation to increase the efficiency of our homes but airtightness in new and existing properties is now something that is imperative if an energy-efficient result is required.

Ventilation is crucial for a warm, airtight home, but it is often the forgotten part of the energy efficiency equation. Insulation is great, and more is better, but even a highly insulated wind tunnel will not hold heat. If your house isn’t airtight then the insulation applied cannot work properly, as the heat is simply lost in the air.
