VINNAPAS®

WHY TO INSULATE AND CURRENT SITUATION OF INSULATION IN COLD STORAGES IN INDIA

• Conserve energy and save money

• Increase profitability

• 90% of existing cold storages are using inappropriate insulationmaterial (as per NHB expert committee report 1.1.1)

• level of insulation are very low (as per NHB expert committee report 1.1.1)

• 13 bil$ of fruits and vegetable get wasted annually (as per ISHS)

NHB= National Horticulture Board

ISHS= International Society for Horticultural Science


VINNAPAS®

PU, MINERAL WOOL & PF BOARD AS INSULATING MATERIALS

PU Boards:

Insulation effect much better than with conventional EPS boards

Thermal conductivity 0,022W/mK

brittle material - low impact strength

low flammability but highly toxic gases in case of fire

Phenol Formaldehyde Boards:

Thermal conductivity 0,022 W/mK

Insulation effect much better than with conventional EPS boards

comparable to PU boards

brittle material – low impact strength

severe shrinkage – very sensitive against water!

Mineral Wool

Mineral wool has a extremely open structure,

high water vapor permeability

TECHNICAL REQUIREMENTS FOR THE MORTARS (MOST IMPORTANT)

� Adhesive mortar: good adhesion (high tensile adhesion strength) on various substrates

� Base coat mortar: high impact resistance, high flexibility and good

adhesion on various substrate)

� Finishing coat mortar:low water absorption and high impact resistance, good adhesion to the base coat

The technical performance depends on dosage (amount) and type of polymer used in

combination with cement

Exposure of system under practical conditions: from - 40°C up to +70°C
