The limitation of fire class and halogen containing flame retardants are two significant issues for polystyrene based insulation materials. In this chapter, the necessity of external thermal insulation composite systems and related concepts are briefly introduced. Then, based on the approaches in literature to halogen-free flame retardants for polystyrene, melamine derived and expandable graphite based substances on polystyrene production and properties are investigated. Flame retardants were added both during the polymerization reaction and also blending. Chemical and mechanical properties are investigated by means elemental analysis, high temperature gel permeation chromatography, thermal gravimetric analysis, tensile and flexural strength together with Young’s and elastic moduli. Moreover, the horizontal fire class tests were also performed. According to results, except virgin PS could not pass while all blended materials passed UL 94 HB test.
