Built-up roof finishes

SIG Design Technology

SIG D & T’s Rhepanol hg membrane system is the perfect solution for all forms of green roofing, particularly intensive green roofs, or roof gardens, which are designed to provide recreational space for the building’s occupants.

A solid foundation for waterproofing for green roofs, Rhepanol hg is a root and rhizome barrier and carries FLL accreditation.

Made from 70% natural materials, Rhepanol hg is the perfect sustainable solution.

Rhepanol hg is also suitable for Biodiverse roofs; another form of semi-extensive green roof (i.e. low maintenance) that makes use of recycled materials intended to create a natural wasteland for flora and fauna of all kinds.

For PVC applications, Rhenofol CG is reinforced with a glass fibre mat and can be used as a root and rhizome barrier.

Rhenofol CG is an attractive and economical solution that is quick and easy to install. Proven over 40 years, Rhenofol PVC is not as temperature-sensitive as other membranes and is up to 30% more efficient to weld.
