These days, we all worry about how much energy our homes use. The rising cost of our energy bills and our impact on the environment mean we want to keep our consumption to a minimum. One of the best ways to do this is to choose thermally efficient products that keep warmth in and cold out, saving money and emissions.

SafeGuard composite doors are one of the UK’s leading brands of residential doors, manufactured and assembled using only the best of components, you can rest assured these hand built doors are amongst the best available. The alphabetical, colour coded scales shown in this brochure follow the same grading system as that found in white goods with ‘A’ representing the most energy efficient. The testing shows the thermal efficiency of each of the doors. The darker the blue, the less heat is being lost. Reds and greens – the predominant colours on the timber door – indicate high heat loss. Doors were tested at the University of Salford’s Energy House. This represents a typical Salford 1919 terraced house and its construction represents 21% of the UK’s current housing stock. The house has been reconstructed in a fully environmentally controllable chamber, in which climatic conditions can be maintained, varied, repeated and patterns monitored. For the test, the inside temperature of the Energy House was 25ºC with an exterior temperature of 5ºC.
