IKO ULTRA Torch-Free (T-F) Detailing Underlay is a polyester reinforced bitumen membrane used as an underlay within a built-up roofing system. The membrane is coated on both sides with a self-adhesive bitumen, SBS elastomeric coating.
The upper surface is protected with a protective film that facilitates rapid bonding of the waterproofing layers. The self-adhesive coating underside is protected by a release film. The underside has a self-adhesive bitumen coating for fully bonded and all waterproofing detailing applications.
The IKO ULTRA T-F Detailing Underlay is used as a fully bonded detailing underlay within a built-up roofing specification system. It is to be used for all associated detailing, abutments, internal gutters, and penetrations as part of a two-layer built-up roofing application.
All detailing works must be undertaken in accordance with the IKO detail drawings and IKO specification documents.
