What To Put Under Laminate Flooring In Basement

Essential Aspects of Choosing an Underlayment for Laminate Flooring in Basements

Installing laminate flooring in a basement requires careful consideration of the underlayment. Here are key factors to guide your decision:

1. Moisture Resistance

Basements are prone to moisture, so moisture-resistant underlayment is crucial. Choose materials such as polyethylene or closed-cell foam that repel water and prevent moisture from damaging the flooring.

2. Insulation Value

Underlayment provides insulation, making the floor warmer and reducing heat loss. Consider materials like cork or rubber, which offer excellent thermal insulation properties.

3. Sound Absorption

Basements tend to be noisy. Sound-absorbing underlayment can minimize impact noise and create a quieter living space. Cork and felt are excellent sound-absorbers.

4. Thickness

Underlayment thickness affects the overall height of the flooring. Choose a thickness that is compatible with your laminate flooring and the existing subfloor. Common thicknesses range from 2mm to 10mm.

5. Cost

Underlayment cost varies depending on material and thickness. Determine your budget and research the cost of different options to find a suitable balance between price and features.

6. Installation Ease

Some underlayment materials are easier to install than others. Consider the ease of installation if you plan to DIY the flooring project. Self-adhesive underlayment or roll-out sheets can simplify the process.

7. Compatibility

Ensure the underlayment you choose is compatible with your laminate flooring. Some types, such as waterproof laminate, require specific underlayment materials designed to handle moisture.

Types of Underlayment for Basements

Common underlayment options for basements include:

Polyethylene (PE): Moisture-resistant, affordable, and easy to install.
Closed-cell foam: Moisture-resistant, provides insulation, and reduces sound.
Cork: Excellent moisture resistance, insulation, and sound absorption.
Rubber: Durable, sound-absorbing, and thermal insulating.
Felt: Cost-effective, sound-absorbing, but less moisture-resistant than other materials.

Conclusion

Choosing the right underlayment is essential for the longevity and performance of laminate flooring in basements. Consider factors such as moisture resistance, insulation, sound absorption, thickness, cost, installation ease, and compatibility. By selecting an appropriate underlayment, you can create a comfortable, durable, and moisture-resistant flooring solution.
