HT 180 Sand is intended for use as an underlay or capsheet in a bituminous built-up roofing system.
The material consists of a special high strength core of continuous polyester coated with bitumen and surfaced with fine sand.

The core of HT 180 Sand is formed from a polyester carrier weighing 180g/m².

The carrier is fed through tanks containing stabilized liquid bitumen which coats it to an approximate thickness of 2.2mm in one continuous operation.

As the material emerges from the tank it is coated with a top surface finish of fine sand. Sand is applied to prevent sticking in the roll.
