Have you found yourself wondering 'what is a thermal bridge?' It's an important question in the world of energy efficiency and the answer plays a critical role in keeping your home warm and cosy. 

Think of thermal bridging as the uninvited guest that slips through your insulated walls, impacting your building's temperature regulation. The culprits? Areas such as wall corners, windows, doors, and the junctions where your ceilings and floors meet.
