Things You'll Need:
- Carpet specifications
- Room measurements
-
Step 1
Establish the carpet padding thickness required. Each type of carpet comes with recommendations from the manufacturer for the under layer of floor padding.
-
Step 2
Identify the type of sub-floor upon which the carpet will be installed. Clarify whether concrete sub-floors are slab on grade, which could require thicker moisture-resistant backed carpet padding.
-
Step 3
Determine whether radiant floor heating is embedded in the floor. Select carpet padding with a lower "R" value so that it is less resistant to heat rising up through the floor covering.
-
Step 4
Verify the warranty offered on the carpet padding. Look for a lifetime warranty and evaluate the definition of "lifetime".
-
Step 5
Choose carpet cushion with higher density for rooms where there will be a greater volume of traffic. Select lower density carpet padding for floor space that will have less traffic.
-
Step 6
Purchase the same yardage of carpet pad as the actual carpet so that the floor space is completely cushioned.
