Type 1		Type 2
	As a product without a surface material, it presents the advantages of flame-retardant and self-extinguishing properties of PIR insulation materials in an economical way and reduces the concerns of spread of fire.		This is a product with a surface material, which can be chosen according to user needs. Various surface materials, including non-woven fabric, paper, vapor barrier, aluminum, etc., can be used to improve workability and broaden the scope of application.
