Features

Protech 4 and 4E comprises of an APP-modified bitumen matrix
which has been combined with a composite core of polyester
and glass fibre.

This composite carrier imparts high tensile strength and dimensional stability. It is centrally located in the sheet's
thickness which results in greater flexibility and ease of torching.
