Why Choose Tapered Insulation?

Falls should be incorporated into the roof to ensure sufficient water channelling and drainage to avoid standing water or ponding.

Problems associated with standing water on roof decks include additional weight on the structure from standing water (causing deflections to the roof’s structural deck), reduced lifetime of the waterproofing system and health & safety risks to building maintenance operatives (ice formation and moss/algae can cause slip hazards).  Standing water will most likely result in refurbishment of a roof area or even the entire roof much earlier than intended.

If the roof fall cannot be provided within the structure then the provision of a fall within a warm deck flat roof is normally achieved in one of three ways:
• tapered insulation;
• timber firrings under a plywood base; and
• screed laid to falls.
