The old stratigraphy is not adherent, still retains dampness and has been stabilised with nailing all over the entire surface and the detached covering of the projecting parts has been removed. Therefore, to avoid bubbles, a new flame-bonded vapour barrier in semi-adherence is needed, consisting of TECTENE BV BISTRIP EP/V or, for high vapour production environments, of TECTENE BV BISTRIP EP ALU POLIESTERE. Before laying the BV, the edge between the vertical and flat parts must be reinforced with a DEFEND or DEFEND ALU POLIESTERE strip which will bring forward for 5 cm the thickness of the thermal insulation on the vertical element.
