Saving these materials from landfill, giving them value and recycling them into a long-life product, provides a harmonious solution to sustainable living.  The highly versatile Hyperion® Cladding comes with 15 year limited residential warranty against splits, splinters, rot and fungal decay. This low maintenance solution is therefore the perfect choice for your Garden Room which is available in a variety of colours, please see below (call us today for a free sample pack).
