Installing laminate flooring? Great choice. It’s affordable, stylish, and durable. But there’s one detail many people overlook: Underlayment. It’s not the star of the show, but trust me, it plays a big role. The right underlayment can make or break your laminate flooring installation. In Pueblo, CO, where the climate swings between dry and humid, choosing the right one matters even more.
Let’s walk through what you need to know so your laminate flooring performs at its best.
What is underlayment, and why does it matter?
Underlayment is a thin layer that goes between your subfloor and your laminate planks. It serves several purposes:
· Absorbs sound
· Provides cushioning
· Evens out minor imperfections in the subfloor
· Adds insulation
· Helps with moisture protection
If you skip underlayment or choose the wrong type, you could end up with noisy floors, poor insulation, or worse—damage from moisture. That’s the last thing you want after investing in new flooring.
Know your subfloor before you choose
Start with what’s already in your home. Are you installing over concrete or plywood? Different subfloors require different underlayments.
· Concrete subfloors: These need moisture protection. Always choose an underlayment with a built-in vapor barrier or add a separate moisture barrier.
· Wood subfloors: These are less prone to moisture, so you can focus more on cushioning and sound absorption.
In Pueblo homes, we often see concrete slabs in basements and wood subfloors upstairs. That means you may need different underlayments depending on the room.
Moisture matters in Colorado
Even though Pueblo has a dry climate, basements can still trap moisture. Moisture protection is a must if you're installing laminate floors in a basement or slab-on-grade foundation.
Look for these features:
· Vapor barrier: Blocks moisture rising from the concrete
· Sealed seams: Prevents leaks between underlayment sheets
· Mold-resistant material: Reduces the risk of mildew under your floor
For added peace of mind, some homeowners use a 6-mil polyethylene moisture barrier under the underlayment itself.
Pick an underlayment that reduces noise
Laminate floors can be a little loud. That hollow tapping noise when you walk? Underlayment helps fix that. If noise is a concern, especially in multi-level homes, go with an option that has sound-dampening features.
Look for:
· STC rating (Sound Transmission Class): Higher is better
· IIC rating (Impact Insulation Class): Helps reduce footstep sounds
We usually recommend at least an STC rating of 50 for homes where quiet matters, such as upstairs bedrooms or home offices.
Consider built-in underlayment vs separate roll
Some laminate planks come with pre-attached underlayment. That can save time during installation, but it may not be enough on its own, especially if your subfloor needs moisture protection or extra soundproofing.
Ask yourself:
· Is the attached underlayment thick enough?
· Does it have a vapor barrier?
· Will it meet local building codes?
If not, you might need to add another layer underneath. This isn’t always ideal, so double-check the product specs before you buy.
Match the right features to your space
Every room is different. What works in one space may not work in another. Here’s a quick guide to help:
· Basements: Moisture barrier + mold-resistant underlayment
· Second floors: Noise-reducing underlayment with high STC/IIC
· Main floors: Combo of support and soundproofing
· Sunrooms or enclosed patios: UV-resistant and moisture-proof underlayment
Also think about radiant heating systems. Not all underlayments are rated for them, so if you have heated floors, choose one that’s compatible.
