Installation of the energy-efficient lining Valéron AVA is part of the programme which includes improved flooring, nipple drinkers and step-up multi-tier systems.

The investment is taking place over two years on farms in Fife where the durable radiant barrier has already been installed in seven houses on three farms, with further houses included in the plans for the next 12 months.

"We plan to use Valeron in another five houses this year," said Sam Davison, engineering manager of Noble Foods. "We are currently seeing the benefits of improved ventilation, faster heating and retention of heat, and easier clean down between flocks. Initial results indicate more than 25 per cent saving in gas consumption."

Allan Meldrum, director of Food Chain Innovation, said a saving in brooding costs of up to 30 per cent is being seen by customers in many countries.

"Initial heating up times are reduced to a few hours from the usual 24 hours plus through the insulating properties of Valeron and its ability to seal the unit," he said. "The lining has the ability to reflect 95 per cent of radiant heat, helping to keep birds of all ages in a more comfortable environment in all climates."
