One of the country’s oldest established brickworks, located in an idyllic Cotswold village, has updated its production facilities saving not only time and money but significant amounts of energy – thanks to the use of Marmox Multiboards for the refurbishment of its drying chambers. Ten separate drying kilns have now been upgraded at Northcot Brick’s premises in Blockley, Gloucestershire, with two different thicknesses of the high performance, moisture resisting insulation boards having been employed to infill their walls and roofs.
While Marmox Multiboards are typically utilised in building work as a floating floor beneath tiles and other finishes or as the lining to shower rooms and other wet environments, Northcot identified their rugged long life potential as potentially offering a solution to its persistent problems.
Marmox Multiboards are manufactured from extruded polystyrene or XPS and offer a range of positive physical characteristics in addition to being fully waterproof. They are both light to handle and easy to cut, while still being able to sustain substantial loadings if required.
Thanks to their stability and resistance to the aggressive chemical atmosphere created by the gases emitted from the drying bricks, the Multiboards are proving to offer a greatly extended working life compared to the old rock mineral wool based panels. Even more importantly, they are making it far easier to control humidity levels during the drying process and to maintain the required temperature. The overall temperature has been reduced by five degrees to 750 C and the total drying period by a whole day while they can be switched off at weekends without affecting the cycle, leading to an overall 25% reduction in energy costs.
