Peri Decking used to support 'Bubbledeck' heat-efficient roof. Air is trapped inside the plastic balls and retains heat for longer. The neccessary Decking was erected to details of supplied drawings, the 'Bubbledeck' was delivered to site and lifted in with a crane. The 'Bubbledeck' has a pre-cast concrete base which was temporarily held in position by the Peri Decking. Steel-Reinforcement was fixed in position by qualified Steel-fixers and neccesary Formwork was fixed. Concrete was poured forming a 200mm slab ontop/ attached to the 'Bubbledeck', this Reinforced Concrete is what held the slabs/ 'Bubbledeck in position' once Peri Decking was removed.
