This White Paper examines the cost analysis of the alternatives to tapered roofing systems to provide a fall in a warm flat roof. It concludes that:
- Using tapered roofing systems to achieve a U-value of 0.16 W/m2.K could be up to 26.9% cheaper than using alternative methods to create a fall in a flat roof for drainage purposes.
- Kingspan Thermataper Systems do not need time to dry out, saving time in the scheduling of a construction project
- Kingspan Thermataper systems can be as little as 1.5% of the weight of a solution using screed to falls with a flat insulation board
