Underlayment For Laminate Floors - Is It Actually Necessary?

Laminate flooring is what we call a "floating floor" that requires installation over a subfloor because it lacks the structural strength to bear heavy loads independently. Even though this flooring type features multiple layers, these layers serve to protect the floor material itself, not for additional structural purposes.

So, do you need underlayment for laminate flooring? The answer is absolutely yes. Installing proper underlayment for your laminate floor creates a stronger connection between the flooring and subfloor, which results in enhanced performance for your entire home construction.

Without proper underlayment, your laminate floor will become unstable, lack adequate support, provide poor sound insulation, and compromise the planks' locking system integrity. Think of underlayment as insurance for your investment. A $300 underlayment installation protects your $2,000 flooring project.

How To Choose the Right Underlayment For Your Laminate Floor

Without question, there's no need to ask: "Do you have to use underlayment for laminate flooring?" So we're moving on to the next crucial section where you'll learn exactly how to choose the perfect underlayment for your specific laminate floor situation.

First, we need to identify which type of subfloor you're working with. There are distinct advantages and disadvantages for each type that we need to carefully consider for optimal underlayment installation for your laminate floor.

The Concrete Subfloor Challenge

Concrete subfloors provide the sturdiest foundation, so we won't require any additional structural support from our underlayment. The primary challenge we must address with concrete subfloors is moisture control. Installing laminate flooring without proper underlayment on a concrete subfloor can result in loosened adhesives, warped flooring planks, and serious mold and mildew problems.

That's exactly why you need to select a thin foam pad underlayment specifically designed to prevent moisture from seeping upward into your laminate flooring. The material composition of these pads typically consists of polyethylene or polypropylene - the same waterproof materials used in food packaging and shopping bags.

Working With Plywood Subfloors

While concrete subfloors require a vapor barrier to prevent moisture issues, the situation is completely different for plywood subfloors. Wood needs to breathe naturally since it's an organic material, and installing a vapor barrier like you would with concrete subfloors will make it extremely difficult for the wood to release trapped moisture properly.

When it comes to selecting appropriate underlayment for your laminate floor installation over a plywood subfloor, you can choose virtually any type as long as it doesn't feature completely waterproof materials. Do you need padding under laminate flooring? Probably not if your subfloor consists of plywood, thanks to the natural give that wood provides.

Standard Foam Underlayment: The Plywood Solution

This type works excellently for installing laminate flooring over plywood subfloors. The underlayment features a cushioning layer constructed with thin and soft materials that provide comfort and support. Since this underlayment type is not waterproof, you shouldn't use it for concrete subfloor installations.

Standard foam underlayment typically measures 2-4mm in thickness and costs between $0.30-$0.50 per square foot. The open-cell construction allows air circulation, which prevents moisture buildup that could damage your wooden subfloor over time.

Combination Foam Underlayment: The Universal Choice

This option is essentially standard foam underlayment with an integrated vapor barrier layer included in the design. You can successfully use this underlayment type for both concrete subfloors and plywood subfloors. Of course, the price point will be somewhat higher than basic standard foam underlayment.

The vapor barrier typically consists of a thin plastic film laminated to the bottom of the foam layer. This design blocks moisture from concrete while still providing the cushioning benefits of standard foam. Combination foam usually costs $0.50-$0.75 per square foot and comes in 2-3mm thickness options.

Cork Underlayment: The Premium Experience

This represents the premium soundproofing underlayment option available on the market. Cork underlayment also helps create an even surface before installing your laminate floors. However, since it doesn't provide high levels of waterproof protection and comes with a pretty expensive price tag, you should carefully consider whether this is the most suitable underlayment choice for your specific case.

Cork underlayment is definitely the most expensive underlayment option among these three choices, typically costing $1.00-$1.50 per square foot. The natural cork material provides exceptional sound dampening, antimicrobial properties, and thermal insulation benefits that synthetic materials cannot match.
