It provides insulation and drainage in one, designed to enhance water drainage from flat roofs, which are waterproofed with mechanically fixed single-ply waterproofing. We provide a supporting design service to identify the most cost-effective tapered system design solution for flat roofs to meet rainwater run-off and insulation requirements.
