The IKO SBS Sanded Torch-On Top Layer Underlay is a fully bonded, torch-applied, polyester-reinforced, and SBS-modified bitumen top layer or underlay that can cope with greater ranges of ambient temperature whilst maintaining flexibility.
It has an upper surface finish of sand and a thermo-fusible film on the underside.
The IKO SBS Sanded Torch-On Top Layer Underlay is intended for use as an underlay or intermediate layer within a bituminous built-up roofing system.
It can also be used as a sanded top layer to be protected by further material such as a solar reflective paint, or chippings bedded into chipping compound.
