Extruded Polystyrene (XPS)

WHAT IS XPS INSULATION BOARD?

XPS Insulation Board is a high compressive strength product. XPS insulation is widely used for building envelop insulation & protection from heat ingress. This insulation contains millions of densely packed air cells; the closed – cell structure with continuous skin formed on both side surfaces provides excellent resistance to water, mildew, corrosion and rot. It is also Fire Retardant (FR) as per ASTM Standards.

WHERE IS XPS INSULATION BOARD USED?

XPS Insulation Board is a material of choice for insulating roof, wall, fl oor for various building types including residential, offi ces, hospitals, institutions, hotels, malls, cold storage buildings, etc.

The performance of this insulation for INFILL applications is exceptional. Typical applications include, concrete fl oors, foundations, roadways, rail beds, permafrost protection and other high load – bearing applications.

• Properties shown are representative values for 50 mm thick material tested at 24 (+/-) 1º C
• ‘R’ Means the resistance to heat fl ow; the higher the value the greater the insulation. This insulation must be installed properly to obtain the desired ‘R’ value. Follow manufacturer’s instructions carefully.
• Meets requirements of ASTM C 578 – Type IV
