Some laminate flooring planks come with the underlayment attached to each plank. Underlayment is not optional. If your laminate planks don't have it already attached, we recommend that you buy rolls of underlayment on which to install your laminate floor.
The answer will vary depending on the material used for the floor and the way that the boards are constructed, but, as a general rule, both laminate and engineered timber floating floors do need some form of underlay to have optimal functionality and longevity.
A floating timber floor requires the same underlay as a laminate does. It is always recommended that you use closed-cell foam, which will last the floor's life span.
Laminate flooring is designed to be a floating floor that may be installed over virtually any type of sub floor. And by “floating”, we mean that it doesn't need to be nailed or glued to the sub floor.
To float a floor means to lay it loosely over an underlay. The planks of flooring will, of course, be fixed together, but nothing will be fixing it to your subfloor. It is a very popular method of installation as it tends to be quicker and easier that gluing, nailing or screwing hardwood flooring down.
What are the problems with floating floors? Floating floors can be susceptible to moisture and humidity, which can cause warping or buckling. They also tend to be more prone to gaps between planks due to their lack of attachment.
You might wonder what keeps a floating floor from moving if it's not secured. The individual planks or tiles are heavy and when they are locked together the weight is dispersed over a wide area and the floor acts as one big heavy flat object.
Without underlayment to add a layer between these damp subfloors and the surface flooring, your laminate can quickly become wet, warped, and mildewy, harming its overall integrity. Moisture over time can also break down floor adhesive which causes the floor to start warping.
Because the flooring isn't attached to the sub-floor, it can move slightly when walking over it. However this is often tiny movements, caused by the underlay compressing underfoot. A hollow or echoed sound can sometimes occur when walking over a floating floor.
But, it can also be one of the big disadvantages of floating floors if you live somewhere that experiences extremely high humidity. This is also due to the space between the floor and subfloor. If a lot of moisture accumulates in there, it may contribute to warping, pitting, or mold growth.
All concrete holds moisture in it, it's a characteristic of concrete. So flooring manufactures require you install your floating floor with a vapour barrier. The easiest way to do that is to have it included in your underlayment roll.
Floating floors are not designed to hold the extra weight of cabinets, and over time they can damage the floor and cause more issues in the long run. Therefore, we recommend that you install the cabinets before the floating floor.
If you're planning on installing the flooring yourself, or you want to minimize your labor costs when having engineered flooring put down in your home, your best option is floating hardwood flooring. That's because this type of flooring goes down faster and easier and is more cost-effective overall.
While there are a number of good options in the market, cork and foam are the usual favorites for a laminate floor underlay. Depending on your lifestyle, you may appreciate cork for its thickness and sound absorption; foam, on the other hand, is an excellent, cost-efficient material that works as a moisture barrier.

Underlayment for laminate flooring can come in different materials like foam, cork, felt, and rubber. Foam is usually a cheaper option, while rubber and felt are often a more premium option.
Laminate floors can be installed directly over concrete, plywood, OSB, parquet, vinyl and tile. The underlayment must be applied to the original flooring surface first, and then the floating floor can be installed.
Because the materials simply lay on the subfloor and are rather thin, floating floors typically feel somewhat hollow and are sometimes loud underfoot—especially laminates. This problem can be minimized by installation of a good-quality foam underlayment.
This back-and-forth movement can wreak havoc on a floating floor if it's not installed correctly. The snapping sounds are almost always traced to an uneven subfloor. Laminate flooring materials don't tolerate humpy and bumpy subfloors. Subfloors need to be quite flat.
A floating floor with great materials, structure, and properly cared for may last anywhere from 40 to 80 years or even more. If you're using thin and low-quality floorboard planks, expect a shorter floor lifespan.
