Icopal's Anderson Elastotherm Torch-on Capsheet Range of Roofing Membranes

Anderson Elastotherm Torch-on Range

Anderson Elastotherm®  is intended for use as a partially bonded single layer top sheet within a bituminous built-up roofing system. The membranes utilise a stripe technology which plays a special role by allowing any trapped water vapour to disperse through the system eliminating blistering created by the build-up of water vapour pressure within the roof construction.

Elastotherm® is suitable for use in a warm roof over suitable insulation, or to refurbish ageing roofs which have not yet been damaged by water ingress and are structurally sound. The self-finished mineral surface provides a decorative and solar reflective finish for the built-up waterproofing system.

Features & Benefits

  • 30% faster application than traditional torch-on membranes.
  • Technically advanced low heat-reactive bitumen .
  • Striped resinous profiles to help eliminate blistering and prolonging roof life .
  • Lap security gives maximum resistance to wind uplift


Detailing to edges of Elastotherm roofs are carried out using Expandrit Plus fully bonded mineral surfaced detailing capsheets
