We install false ceilings for shops or offices. The cost is 70 BDT per square foot for PVC boards, and 75-80 BDT for gypsum boards. These are installed using aluminum channels. If you choose powder-coated channels, the cost is 65 BDT for PVC boards and 70 BDT for gypsum boards. These are brand new and suitable for tin-shed houses or offices. We have various designs for PVC and gypsum boards available for you to choose from. Gypsum boards are typically used to keep the AC cooling inside.
