Hello Lakshmi, There are a lot of materials that can be used and many of them have good life. Our preference is with BWP ply/board laminated on both sides. It works good and is price effective as well. Please go for branded ply only. Thanks, Amit CORNERSTONE DESIGNS Bangalore.

HDF is High Density Fibreboard as opposed to MDF which is medium density fibreboard. If sealed properly it can be used outdoors as panels set within hardwood frames. Better still is marine grade plywood

Sree, There are so many products that can be used for finishing a TV unit. Laminates, Veneers, Glass, Charcoal, WallPaper, MDF, Duco, PU, Wooden & Stone Claddings .. just the few that come to top of mind. But what is that you wanted to understand about these. Thanks, Nitin Cornerstone Designs, Bangalore.

There is nothing special about Kerala climatic conditions that require anything special (yes, I have several years experience with kitchen cabinets there). You can use BS 710 or 303 plywood with laminate on them with excellent results. Several interior firms also use HDF/MDF with laminate without much complaints from their clients.
