Foam emerged as a material extremely effective thermal insulation qualities and high strength to weight ratio at low temperatures. These inherent physical characteristic enable it to perform extremely well with other alternatives products Rigid insulation, minimum 95% closed cells, remains durable for years, no thermal bridges, high mechanical strength.
Polyurethane foam is also available in pipe section form, the thickness of pipe sections that are available are (25,40,50,65,75,100 and 125mm). The internal diameter of PU form pipe sections are available in (15,20,25,32,40,50,65,80, 100,125,150,200,250,300 and 350mm).
