Is Tapered Insulation better than Screed to Falls?

A traditional flat roof construction would involve creating a fall on the deck, which could be screed to fall, timber firrings or metal at a tilt. Tapered insulation removes the need for this and instead creates the fall in the insulation. This is the main benefit of using a tapered system over a more traditional method -  the system itself is designed to ensure no water ponding on the roof, avoiding issues like slip hazards, stress on waterproofing membranes and a poor aesthetic appearance.

Other benefits include:
  • By using tapered roof insulation, you could achieve a saving of up to 26.9% over traditional methods.
  • Tapered insulation is as little as 1.5% the weight of screeds, therefore allowing a cheaper deck structure.
  • Tapered roofing can be created based on an area weighted U-value or an average U-value across the roof, further reducing the cost.
  • Tapered insulation eliminates drying out time, which is needed for screed to falls, which means it is usually the faster option and contractors do not have to rely on a third party to create falls correctly.
