The invention relates to creating health benefits from an energy efficient thermal insulation device of a reinforced impermeable aluminum sheet combined with a protective cover divided into a number of air filled square and rectangular shaped modules that provide health and comfort benefits by improving indoor and outdoor air quality and indoor air circulation by reducing energy flux through the building fabric where the insulating device is fixed to a wall or free standing behind a heat emitter and thereby reducing the heating fuel consumption and therefore storage requirements of heating fuel and thereby extending fuel reach for the fuel supplier and reducing carbon dioxide emissions into the atmosphere.

A radiator containment bag includes a bag section configured as a container and sized and shaped so that in use at least the lower end of a radiator fits within and is retained by the bag section. The bag section is formed at least partly from a waterproof material so that liquid in the bag section will be retained within the bag section. At least one containment strap is connected to the bag section and is configured to pass over and around the top of a radiator located in the bag section in use to hold the radiator in the bag section. A plurality of grab handles extends from the bag section and are configured to allow a user or users to grasp the handles to lift the
