Product Introduction
Bead Method Insulation Board Type 2 (EPS)
Known by trademarks such as Neopor and Zeroboard, and referred to internationally as Grey EPS, this insulation material is manufactured by adding graphite, a carbon-containing synthetic material, to bead method insulation materials.
This addition enhances the product's insulation capabilities against radiant heat by increasing its heat accumulation capacity.
Offers approximately 9% better insulation than Bead Method Insulation Board Type 1.
Can be installed at 15-20% thinner than Bead Method Insulation Board Type 1, allowing for a more efficient use of space.
Composed of independent microbubble structures, making it resistant to moisture and mold.
High absorption rate; insulation performance decreases when water is absorbed.
Vulnerable to heat and prone to deformation, with weak resistance to chemicals.
