Insulation work

Step 1: GI Duct surface iscleaned and all the dust particles are removed. Also remove any grease or debris if present.
Step 2: Apply Duct Adhesive on the GI sheet with the help of brush or roller on all the 4 side of the rectangular duct.Starglue 81-10 applied with brush or roller
Step 3: Wait 10-15 minutes and when the surface becomes touch dry, the fiber glass wool insulation is wrapped on the surface of duct.
Step 4: In order to protect the fiber glass insulation from external damage, canvas cloth is wrapped around the glass fiber wool insulation.
Step 5: To bond the Canvas Cloth with the fiber glass wool insulation, a water based thermal insulation is used. Thermal insulation coating is applied with a brush or roller. It provides excellent heat and UV resistance. It is very important to ensure that each coat is totally cured before the next coat is applied.
Step 6: To counter the possibility of mold and fungus growth, an Anti-Fungal Duct Coating is applied on top of the Thermal Insulation Coating. It is very important to ensure that each coat is totally cured before the next coat is applied.
Step 7: When Ducts are in an Open Atmosphere, there is a high chance of rain and moisture causing damage to the Insulation Coating. In order to protect the Duct System a specialized Vapor Barrier Coating is applied so that the surface becomes anti-fungal, fire retardant and waterproof. Some applicators may directly apply over the Thermal Insulation Coating. It provides excellent water resistance & tough weather protection.
