Gradient provides school with flat roofing system

Gradient Flat Roofing has refurbished a school roof, highlighting the company's ability to create factory-cut bespoke insulation to suit specific projects.

The roof of the Simmondley Primary School in Derbyshire was originally constructed using a factory-produced cranked beam system, creating a series of varied ridges and valleys across the entire roof area.

These were topped with a built-up felt and gravel surface layer.

The roof design had allowed water to pool in various places, creating areas of thermal stress which had caused the felt layer to degrade.

Derbyshire County Council asked Gradient to design a new insulation layer which would eliminate the existing valleys and backfalls and allow the entire roof to drain effectively.

Gradient proposed a combination of cork underlay board and PIR insulation.

The resulting roof would also provide thermal insulation which exceeded building regulation requirements.

The 23 week project was completed with the application of a 3-ply built-up mineral felt surface layer over the Gradient insulation.
