Every Home Should Take This Test!

What is Air Tightness Testing and how can it help in draught proofing your home?

This week Robert is joined on location by Dean Fielding from the charity Zero Carbon World and also Fully Charged LIVE’s Home Energy Advice Team.

They’re in a domestic property to see one of the most effective and cost efficient tests you can do to identify where your home is leaking warm air, and therefore energy and money.

Outside of new build developments, air permeability or air tightness testing isn’t widely known, yet it can be very successful in finding areas of your property where warm air is leaking out.

By identifying and fixing these problem areas there is the potential to make your home warmer, quieter and more comfortable to live in, whilst at the same time saving you money on your energy bills.
