SIG Design & Technology - BBA Accreditation for SIG SIGnature 25 Waterproofing System

BBA Accreditation - Roof Bitumen Waterproofing - Membranes Waterproofing

SIG - Layfield School

SIG’s SIGnature 25 roof waterproofing system has been awarded the BBA (British Board of Agrément) certification.

The quality accreditation is for SIG’s own range of Torch-On roofing bituminous membranes. These comprise polymer-modified bitumen waterproofing membranes, insulation boards and a vapour control layer (VCL) for use on flat and pitched roofs with limited access.

Suitable for warm or cold roofs, the SIGnature Torch-On range is available in three underlay options, with the potential for either 20 or 25 year warranties.
