Underlay or underlayment generally refers to a thin layer of cushioning made of materials such as sponge rubber, foam, felt, or crumb rubber. This material is laid beneath carpeting to provide comfort underfoot, to reduce wear on the carpet, and to provide insulation against sound, moisture, and heat.
Floor Underlayment Main Purpose
Sound Reduction or Dampens Noise
Underlayment allows to block sound from transferring from room to room. An underlayment built with recycled fibers absorbs sound and keeps it from traveling to other rooms. Makes click-together floating floors sound solid underfoot.
Moisture Protection – Blocking Harmful Damage To Your Floor
Certain underlayment come with built-in vapor barrier that blocks moisture from getting to your floor. Concrete subfloors is notorious for emitting moisture and causing flooring to be in contact with water and chemicals from concrete.
Consistent traffic can lead to dented areas of your flooring. Dense recycled fiber underlayment supports the click-together mechanism and upholds supportive configuration under consistent traffic of overlying floor.
Smooths Subfloor Imperfections
All subfloors are not consistent in levelness. However, underlayment can form to a certain degree around subfloor surface roughness, helps to cut down on extra subfloor surface prepping time.
Providing additional comfort to the entire home during seasonal temperature changes.
Approved for In-Floor Heating Systems
Allows heat to permeate evenly while helping to protect the floor covering material from thermal shock.
Certified Clean and Safe Indoor Air Quality
Flooring underlayment should not be smelly or give off any weird smells. Always look for some certification for indoor air quality testing done. This protects your family from getting unwanted headaches or sickness.
An underlayment shouldn’t break the bank but protect you from moisture and reduce noise.
It is always best to review your flooring installation instructions to follow what they recommend for underlayment. Some flooring manufacturers don’t call for such material and some do. If you are looking to help reduce noise, consider an underlayment that does sound absorption with moisture protection/management.
