Teachers and pupils at a Brighton school have come up with a hairy way of fulfilling their building's insulation needs.
As part of their efforts to boost the efficiency of the Dorothy Stringer establishment's environmental centre, the planet-conscious academics shaved their heads to provide a 'renewable' insulation source.
In addition to their tresses, sheep's wool, hemp and cotton have been harnessed to fill the walls of the centre, with thermometers fitted inside and outside walls to ascertain which material is the most effective.
"Everyone has really got behind the project. Each day, I find another pupil has dropped off a bag of hair for us to use after getting their hair cut," ecology teacher Rob Sandercock told The Argus.
"At the moment it's really useful because we need as much as we can get," he added.
Mr Sandercock went on to echo the views of an increasing number of green homes specialists, who acknowledge that making buildings 'airtight' with effective insulation is key to going zero-carbon.
Double glazing is proven to save heat and energy lost through poorly-insulated windows and doors. With Energy Efficiency windows and doors as standard, homeowners can now save even more on their heating bills and reduce their carbon footprint.
