DMX SoundGuard™ is a premium underlayment designed to provide superior noise reduction and warmth for your floors. Its tri-layer design offers sound insulation, thermal comfort, and moisture protection, making your living space quieter and more comfortable.

It is suitable for use under:
– Engineered hardwood flooring
– Vinyl plank flooring
– Laminate flooring

No, our 12 thou HDPE core provides commercial grade puncture & tear resistance.

The underlayment’s advanced tri-layer design absorbs and reduces impact sound (like footsteps) and airborne sound, eliminating the hollow sound common with many floating floors. It’s tested at IIC-74, which makes it ideal for condos, apartments, and upper levels where sound insulation is essential.

DMX SoundGuard™ can be used in basements, but if moisture management is your top concern, DMX 1-Step 2.0 is the better choice.

DMX SoundGuard™ focuses on superior soundproofing and thermal insulation, ideal for condos, apartments, and upper floors.

DMX 1-Step 2.0™ has an air gap design that allows moisture to evaporate, preventing mold growth, perfect for basements.

DMX SoundGuard™: Designed for condos and upper levels. Provides exceptional noise reduction, warmth, and comfort.

DMX 1-Step 2.0™: Designed for basements and concrete floors. Features an air gap system to manage moisture and prevent harmful mold growth.

Yes! The reflective foil layer radiates warmth back into your flooring, adding a layer of comfort underfoot.

We do not recommend DMX SoundGuard™ for basement or slab-on-grade installations. For
these applications, we strongly recommend DMX 1-Step 2.0™, which is designed to allow
moisture vapor from concrete slabs to dissipate. Without this airflow, moisture can become
trapped and may lead to mold or mildew.

This is very common in the flooring industry. Flooring manufacturers often do not test or
approve flooring underlayments in their systems. We took note of this, and our warranty is
reflected as follows: When installed according to the DMX SoundGuard™ Installation Guide,
DMX assumes responsibility for: DMX SoundGuard™ and the affected floor covering in the
event of a failure related to the product for a duration of 25 years from date of purchase.

As heat travels downward through the floor, DMX SoundGuard’s aluminum layer reflects
radiant heat back toward the living space, helping maintain floor temperature.

DMX SoundGuard™ is only 1 mm thick, making the height difference nearly indistinguishable
compared to installing flooring without an underlayment.

Yes. Every roll of DMX SoundGuard™ comes with a FREE roll of DMX Joining Tape, so you can properly seal the seams without additional cost.

Perfect for:

• Home offices or any space where sound reduction is important
• Condos and apartments
• Upper levels of homes

For basement or slab-on-grade applications, we recommend DMX 1-Step 2.0 for vinyl (5 mm
or thicker), laminate, and engineered hardwood.
For above-grade installations where moisture is not a concern, DMX SoundGuard is still
recommended because it:
● Reduces sound transmission
● Reflects heat back into the living space
● Improves underfoot comfort
● Offers superior durability and tear resistance compared to typical attached pads

DMX SoundGuard™ can be used under the following floor coverings:
● Vinyl (plank, peel-and-stick, and glue-down)
● Laminate
● Engineered hardwood
● Solid hardwood (nail-down or click systems)

Install DMX SoundGuard™ with:
● The white side facing the subfloor
● The aluminum foil side facing the flooring

Each roll of DMX SoundGuard™ includes a generous amount of DMX Joining Tape. If
additional tape is needed, a standard sheathing tape from your local hardware store is
acceptable

No. DMX Easy Shims™ are only compatible with DMX 1-Step 2.0. DMX SoundGuard™ is a flat
underlayment and does not have the profile required to nest the shims.

Under the “Test Results” tab on our website, both homeowners and condo boards can
access third-party test data for DMX SoundGuard™ to verify its performance claims.

To minimize joint overlap, we recommend installing DMX SoundGuard™ perpendicular to the
direction of the flooring.
Example: If your flooring runs in a north–south direction, install SoundGuard east–west, or
vice-versa.

No. Double stacking is not recommended. If additional sound reduction is required, consider
a floor covering with a manufacturer-approved attached pad, which is specifically designed
for that purpose

IIC (Impact Insulation Class) measures how well a floor assembly reduces impact noise such
as footsteps, running, or dropped objects. The higher the IIC rating, the less noise transfers
to the room below. DMX SoundGuard has an IIC rating of 74, which is considered very high
for residential applications.

Leftover material can be reused in many ways, including:
● Under area rugs
● Inside closets or mudrooms
● Cold storage rooms
● Under workout equipment

DMX SoundGuard™ is often used as a cost-effective alternative to radiant heating. If you plan
to install radiant floor heating, we recommend confirming compatibility directly with the
radiant heat manufacturer, as DMX does not test SoundGuard with these systems.

If DMX SoundGuard™ was installed according to our Installation Guidelines, it can remain in
place. But before installing new flooring, ensure the subfloor is still level and structurally
sound, as minor changes can occur over time
