FAQ'S

 

 

What is the purpose of the carpet underlay?

 

   The main purpose of the underlay is to provide the carpet extra wear resistance and to prolong the carpet's life. The other purposes of the underlay are to provide underfoot comfort, dust suppression and sound and thermal insulation.

 

Do I need underlay?

 

   If your new carpet has jute backing, secondary backing, action backing or is a woven carpet , then the answer is yes, unless your intention is to fully adhere the carpet to the subfloor. The only drawback when not using underlay is that you will not be able to enjoy the luxurious feel and thermal and sound insulation that the underlay provides.

   If your carpet is foam, silicone or rubber backed, then it must be installed straight on the floor, without underlay, using an appropriate carpet adhesive. This sort of carpet is usually used in a commercial environment.

 

Can I reuse my old underlay?

 

   You can, but you will be making a false economy. Even if it looks fine when you install the carpet, it could fail during the lifetime of the new carpet. Furthermore, carpet manufacturers guarantee that their products will perform as well as advertised, only if the carpet is installed on new, good quality underlay.
