29066964_sUSA: Insulation manufacturer Armacell claims that Armacell insulation has been employed in eight out of twelve Brazilian World Cup stadiums.

The new World Cup stadiums in Brazil are said to have relied primarily on products from Armacell when insulating refrigeration installations. In service and administration facilities, the insulation material protects the chilled-water pipes and air ducts of the air conditioning systems against condensation and energy loss.

While extensive renovations equipped six existing arenas for the championship, the six other stadiums were new construction. The sporting venues in which Armacell products were installed include the Estádio Nacional in Brasília, the second largest World Cup stadium with a capacity of over 70,000 seats, the magnificent Estádio Mineirão in Belo Horizonte and the Arena da Amazônia in Manaus, the most controversial and – from an architectural point of view – most unusual stadium of this World Cup. All in all, more than 150,000 linear feet of insulation tubes and nearly 50,000ft² of sheet material were installed in eight World Cup stadiums and the  Arena Grêmio in Porto Alegre, which was constructed at the same time.
