What Do You Put Under Vinyl Flooring? A Comprehensive Guide
Choosing the right underlayment for your vinyl flooring is crucial for maximizing its lifespan, comfort, and overall performance. The best option depends on several factors, including the type of vinyl flooring you've chosen (luxury vinyl plank (LVP), luxury vinyl tile (LVT), sheet vinyl), your subfloor's condition, and your budget. This guide will explore the various underlayment options available and help you determine the best choice for your project.
What are the different types of underlayment for vinyl flooring?
Several underlayment materials offer distinct benefits. These include:
-
Foam Underlayment: This is a popular and affordable option, often made from polyethylene foam or polyurethane foam. It provides cushioning, sound insulation, and can level minor imperfections in the subfloor. Different thicknesses are available, influencing the level of cushioning and insulation.
-
Cork Underlayment: A natural and eco-friendly option, cork underlayment offers excellent cushioning, sound absorption, and insulation properties. It's more expensive than foam but provides a higher level of comfort underfoot.
-
Fiberboard Underlayment: Made from compressed wood fibers, fiberboard is a dense and durable underlayment. It offers good dimensional stability and helps to create a flat surface for the vinyl flooring. However, it typically offers less cushioning and sound insulation than foam or cork.
-
Rubber Underlayment: Rubber underlayment is known for its exceptional durability and sound dampening capabilities. It's a good choice for areas with high foot traffic or where noise reduction is a priority. It can be more expensive than other options.
What type of underlayment is best for luxury vinyl plank (LVP) and luxury vinyl tile (LVT)?
LVP and LVT are generally installed over a relatively smooth and level subfloor. For these types of flooring, a thinner underlayment is often sufficient. Foam underlayment is a popular choice due to its affordability and ease of installation. However, cork provides superior comfort and sound insulation, making it a worthwhile consideration, particularly if you have a noisy subfloor or want a more luxurious feel.
Do I need underlayment for vinyl flooring?
While not always strictly required, using underlayment with vinyl flooring is highly recommended. It provides several key benefits:
- Improved Comfort: Adds cushioning and makes the floor warmer and more comfortable to walk on.
- Better Sound Insulation: Reduces noise transfer between floors.
- Subfloor Leveling: Helps to create a smoother surface, minimizing unevenness and preventing the vinyl from showing imperfections.
- Moisture Protection: Some underlayments offer a degree of moisture protection, shielding the vinyl from subfloor moisture.
- Increased Durability: Helps protect the vinyl flooring from damage and extends its lifespan.
What kind of underlayment should I use on a concrete subfloor?
Concrete subfloors can be cold and damp, so choosing the right underlayment is crucial. Foam underlayment with a moisture barrier is often recommended to prevent moisture from damaging the vinyl flooring. Cork underlayment can also be a good option, providing insulation and comfort. Ensure the underlayment is specifically designed for use over concrete.
Can I use any type of underlayment under vinyl flooring?
Not all underlayments are suitable for vinyl flooring. Some underlayments may be too thick, causing the vinyl to buckle or wrinkle. Others might not provide adequate moisture protection or cushioning. Always check the manufacturer's recommendations for your specific vinyl flooring and underlayment before installation. Using the wrong underlayment could void your warranty.
How thick should the underlayment be for vinyl flooring?
The optimal thickness of the underlayment depends on factors such as the type of vinyl, subfloor condition, and desired level of cushioning and insulation. Generally, underlayments range from 1/8 inch to 3/16 inch in thickness. Thicker underlayments provide more cushioning but might require more precise subfloor preparation. Consult your vinyl flooring manufacturer's recommendations for guidance.
By considering these factors and carefully choosing your underlayment, you can ensure a successful vinyl flooring installation that lasts for years to come. Remember to always follow the manufacturer's instructions for both the vinyl flooring and the chosen underlayment.
