Foam backing for doors keeps blade firm green

Hart Door Systems has supplied a range of doors for Clipper Windpower's offshore wind blade facility, a phase of which has been completed at Shepherd Offshore's Neptune Energy Park, Wallsend.

Nick Hart, technical director, says the contract was a challenge in that the doors needed to achieve certain u-values to ensure that building was able to maintain its green credentials.

He says: "We supplied two very large Speedor Maxi doors which are 8m wide x 8m high to enable a production flow through the building to take place immediately adjacent to the river in a very windy environment.

Hart says Speedor is high-speed, automatic and energy saving.

However the large Speedor Maxis required a special foam backing to achieve a U value of 1.44. Insulated roller shutters are also part of the project using the latest high specification insulated aluminium laths.

A further feature of the Speedor Maxi is its ability to withstand winds up to 90 mph. Each door has an insulated roller shutter and a steel fire door exit to either side of it.
