MedO GS EdgeGuard is supplied self-finished as standard but can be supplied powder coated in any colour, contact Radmat Building Products for lead time. Curved lengths are also available. These require a separate jointing piece for each length
Loose lay over a suitable Radmat waterproofing membrane, ProTherm inverted roof insulation WFRL or MedO drainage/retention board.
