NBR Rolls & Sheets

Aerofoam® NBR Rolls & Sheets are made from closed cell rubber foam, which has a microcell, non porous structure and a closed cell content bigger than 90%. They can be coated with different types of foils and can have also a factory-applied self-adhesive backing, depending on the customers’ needs. The Aerofoam® NBR rolls & sheets have a very good dimensional stability and offer an excellent protection against condensation, thermal loss and sound transfer. The installation time is reduced more than 40% due to the cutting easiness and the quick adhesion capacity of the material.


The rolls & sheets represent no hazard to the human health, being used no CFC or HCFC in their production and having a very low VOC level. They are considered environmental friendly products (with low Ozone Depletion Potential – ODP – and Global Warming Potential – GWP) and comply with the LEED requirements, helping buildings to get more LEED points.
