EXTRATHERM80 B2 is the result of a research project aimed at optimizing radiator performance in order to offer a product with excellent mechanical properties and high thermal conductivity. Designed to allow installation in any premises and blend in with any interior style, EXTRATHERM80 B2, entirely made of aluminium alloy, delivers excellent heating performance for homes and commercial buildings.


  • Ideal for low-temperature applications
  • Double coating for lasting finish: anaphoresis + powder coating
  • No welds, so no problems with burrs
  • 100% MADE IN ITALY
  • Light for easier handling and installation

Fondital guarantees all EXTRATHERM80 B2 models for 10 years from the date of installation against all production defects.
