Vacupor® NT-B2-S is a microporous insulation material which has an extremely low thermal conductivity coefficient giving it very good insulating properties.
Vacupor® NT-B2-S consists of inorganic oxides. The main constituent is fumed silica, the other components are opacifiers for minimizing infrared radiation, and silicates
Vacupor® NT-B2-S is approved by DIBT under the certification number Z-23.11-1662.The approval is valid for construction applications DAD, DAA, DZ, DI, DEO, WAB, WAA, WH, WTR and WI according to standard DIN 4108-10, and prefabricated facade panels with insulated glass character.
Vacupor® NT-B2-S corresponds to the material class B2. The examination of fire behaviour according to DIN 4102-1, May 1998, building material B2; no test certicates. H.3-145/07 and H.3-146/07, was issued by the Research Institute for heat protection in Munich.The core material of Vacupor® NT-B2-S is not flammable and classified A1 according to DIN ISO EN 13501-1.
Application
Vacupor® NT-B2-S was specially developed for applications in the building and construction industry where an approval by the building authorities is required.
By using a special metalized multi-layer plastic film, the panel is suitable for applications where there is an increased demand for fire protection. The low density and IR opacifiers contained in these grades, greatly reduce the thermal conductivity of Vacupor® NT-B2-S Systems.
