Prefabricated waterproofing membrane composed of distilled bitumen and elastoplastomeric polymers (APP) reinforced with heavy duty fibreglass mesh for use as a vapour shield. The particular conformation of the upper surface, featuring "dimpled" elements, associated with the particular bituminous compound, allows it to be used as a vapour shield, underneath the insulating element. ISOLVAPOR NB can be successfully used even on steep slopes without compromising the end result.
Advantages:

• Reduction of overall installation times
• Strong grip of the insulation on the membrane owing to the presence of the adhesive dimples
• Easy installation
• Easy and safe installation of the insulating panels obtained with the fusion of the adhesive dimples (more than 1000/mq)
• Safer operation for the contractor without the encumbrance and the danger of a boiler
• A plasto-elastomeric compound that gives the membrane good workability at low temperatures, resistance to mechanical stress and an elastic performance.
