Basic Properties Of Insulation Cores

| Material |
Description |
Characteristics |
| PUR | Rigid Polyurethane Foam | Most popular, widely used, ideal insulator. It is thermosetting material when exposed to fire, does not drip or melt; forms a strong carbonaceous char that protects the core and prevents spread of flame. Additions of FR agents further augment fire retardant properties. It is CFC free & self extinguishing. Conforms to IS-12436-88. |
| PIR | Polyisocyanurate Foam | Offers higher fire rating and is non-ignitable. Better closed cell structure offered by trimerisation process offers better thermal performance. It is CFC Free, longer lasting, hygienic and food safe. Ideal for Cold Rooms. |
| ROCKWOOL | Rockwool | Naturally occurring fibre with very high temperature resistance properties. It is fireproof, emits no smoke or gases, is water repellant & Non-capillary. The process re-orientation of vertical fibre structure imparts high Shear, Compressive and Tensile strength, thus making the Panels strong and stable. Rock wool with excellent acoustic properties is chemically neutral, vermin proof, re-cyclable and bio degradable. Ideal for Partitions, Internal walls, Acoustic Insulation, and FR & HT applications for Power Plants etc. Conforms to IS-8183. |
