Cold Storage

Cold Storage applications create one of the most hostile environments to which insulation can be exposed due to large temperature differentials and associated severe water vapor pressures. Twiga Insul is the most patronized product for cold storage application in India.

Apart from its thermal performance (with Twiga Insul, excellent thermal conductance value (U Value) can be achieved), other major check point is Fire safety of material in Cold Storage for Partition and Ceiling/ roof applications.

Fiberglass wool conforms all the stringent fire standards including BS 476 (part 4,5,6 and7).

-BS 476 Part 4: Non combustible

-BS 476 Part 5: Class P (highest class in Ignitibility test)

-BS 476 Part 6: Fire propagation (main index<12, sub index<6)

-BS 476 Part 7: Class 1 (Surface Spread of Flame is NIL)

Twiga Fiberglass wool is completely fire safe material & it is Class ‘O’ and Class 1 material which is the highest rating in fire standard. * (LINK TO Twiga Insul )
