Distinction Doors has just received the test results on the energy efficiency of its 44.5mm composite door. It was tested in comparison with a well-known 48mm solid timber core composite door and a 44mm timber panelled door. The results were astonishing. The Distinction composite door was proved to be 19% more thermally efficient than the 48mm solid timber core composite door and 17% more thermally efficient than the 44mm traditional timber panelled door.
Dave Walker, Distinction’s Technical Director said, “We’ve always known that our composite doors offer excellent thermal efficiency. These test results prove this to be the case.”
The doors were tested at the University of Salford, which is renowned for its work in energy research and innovation. The test was conducted in the University’s Energy House. This is a typical Salford 1919 terraced house that has been reconstructed in a fully environmentally controllable chamber, in which climatic conditions can be maintained, varied, repeated and patterns monitored.
Dave Walker and his technical team at Distinction Doors project managed the testing. Working with the team at the University of Salford, they tested Distinction’s 44.5mm composite door, a 48mm solid timber core composite door and a 44mm timber panelled door. For the test, the inside temperature of the Energy House was 25C with an exterior temperature of 5C.
The photos show 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. The scores of each door are also shown; the lower the score the more thermally efficient it is. The Distinction composite door scored 6.8, the 48mm solid timber core composite door scored 8.4 and the 44mm timber panelled door scored 8.2.
Dave Walker concludes, “We have always known about the thermal efficiency benefits of our high density polyurethane foam core composite doors. Now our customers have the official proof that they are better than the alternatives, something that we know will help them to close more sales.”
