Usually, Yes! A carpet pad is necessary to protect your carpet. The pad keeps the underside of your carpet from wearing against the subfloor. It also absorbs the impact from footsteps and furniture, lessening the stress on the carpet. In addition to offering protection, the right carpet padding provides thermal insulation and reduces sound within the room, helping to make living spaces more comfortable. Choosing your padding is a very important step in your carpet's performance.
There are certain types of carpet that are appropriate for a glue down installation. The carpet is glued to the subfloor and no padding is used. You usually find glued down carpet in businesses or residential kitchens or baths. Your Lowe's specialist can let you know if the type of carpet you have chosen is appropriate for a glue down installation.
