Air leakage can cause you to lose up to 30% of a dwelling’s heat, making the building less energy efficient and more expensive to run.
After looking at drawings and ensuring the building is suitably sealed, our technicians will temporarily fit a fan into a doorway to calculate the air flow within the building under different pressures. This will reveal the air leakage rate and determine how energy efficient your building is.
L1 Testing support you the entire way – from the booking to the execution of your Commercial Air Pressure Test. We provide same-day pass certificates upon successful completion so that you can get your building signed off in a timely and stress-free manner.
