Serenity Mat™ Flooring Underlay

Serenity Mat Floor Underlay can reduce footfall noise (IIC) and block airborne sound (STC) all in one step. Serenity Mat Floor Underlay can be used on many floor types, with any sub floor assembly, without making any changes to your current construction.

For details on soundproofing your floor make sure you take a look at our “How to Soundproof a Floor” solution article. If you can not deal with the problem floor itself and want some peace a quiet in the room below make sure you read “How to Soundproof a Ceiling“.

  • 93% Recycled Materials and Made in USA
  • Serenity Mat adds weight to the floor, blocking airborne sound giving it a high STC rating.
  • Serenity Mat absorbs the noise from footsteps on rigid floors. You will hear fewer footsteps from above.
  • Serenity Mat™ Underlay will be used to “float” a new double layered sub floor, effectively decoupling the direct connection An excellent option when compared to poured gypsum topping and an additional plywood subfloor.
  • Serenity Mat Floor Underlay can be glued down directly for Engineered Hardwood.

How Serenity Mat Works

Compare the springs on the right. The first spring is in a resting state and uncompressed. If we apply energy to the top of the spring it compresses, then will oscillate up and down until it comes to rest expending all the compression energy. Serenity Mat™ behaves just like the spring.

All of this takes place in a fraction of a second. Serenity Mat™ Flooring Underlay uses a proprietary blend of recycled rubber with different density (Durometer) material to broaden the effective frequency range of isolation.

Because of the need for oscillation to reduce the impact, we have to take care not to insert screws and nails that will lock the movement of the mat and reduce oscillations. Nails and screws will partially reduce the performance

FAQ – Frequently Asked Question about Serenity Mat™

Q – What is the difference between thinner and thicker underlayments?

A – Mass is a big contribution of soundproofing underlayment. The thicker the underlay is layers means it will oscillate more slowly. This slower oscillation with help guard against lower frequencies better than thinner underlays. Average mid-frequency noise is audibly improved as the thickness increases.

Q – Can I build walls on Serenity Mat™ Soundproofing Floor Underlay?

A – You can. You’ll be anchoring to the upper ply layer floated on rubber. Easier to attach wall plates to the original subfloor or slab.

Q – Do I use Glue when installing Serenity Mat™?

A – Glue is recommended. The glue assists with sound isolation as well as keeping the rubber from shifting during flooring installation.

Q – What if I want to protect the old floor and don’t want to glue to it?

A- Float the new floor. Cover old floor with the rubber without adhesive.
