Areas of application
EVT Backing Material (Fire Rated) may be used in expansion joints, connection joints and profile glass sealing, in areas requiring fire protection, in order to increase the joint depth and avoid triple-surface adhesion.
Properties

Application
Use the backing material in the dimensions specified in the table below, thus, any bad fitting of the sealant is avoided. Insert the backing material up to the required depth without stretching or compressing it.

To achieve the desired fire protection, please follow the figures given by the table.
