The traditional method where you need to cut the insulation and roof covering, which provide more material consumption.

Grade Roof's circular fall. No cutting of insulation or roof cover when building drainage to the drain.

Flexible system that can be turned to the location of the drain.

The video says more than 1000 words. Here you can see three roofs (52m²) of stone wool being laid in parallel. You will gain insight into the differences in planning and the method for laying both insulation and roof covering.

Before GradeFloor AS introduced the circular fall to flat roofs, the 4-way fall was essentially the best option. It will therefore be more accurate to compare it with the 4-way fall. 

The savings are not just related to the laying of the insulation. The roof cover is also applied much faster on the GradeRoof ™ insulation. It will also become easier to glue and wield. The simplest is often the best.
