Flooring Underlay Buying Guide

What Is Flooring Underlay?
Flooring underlay is a layer installed beneath
compatible flooring systems. Its purpose depends
on the product and type of flooring.
For example, carpet underlay can add comfort
and support. Meanwhile, suitable hard-floor
underlay may provide acoustic performance,
support or other installation benefits.
Why Is the Right Underlay Important?
Underlay forms part of the complete flooring
system. Therefore, choosing a compatible
product is important for installation quality,
comfort and long-term performance.
However, thicker or softer underlay is not
automatically better. Density, compression
resistance, construction and manufacturer
approval also matter.
Carpet Underlay
Broadloom carpet generally uses a compatible
carpet underlay. It helps support the carpet
and can influence the comfort and feel
of the finished floor.
Carpet underlay comes in different materials,
densities, thicknesses and grades.
The best option depends on the carpet,
traffic level and intended use.
Carpet Underlay Materials
Carpet underlay may use foam, rubber
or other resilient materials.
Different constructions provide
different levels of support and comfort.
When comparing options, consider
the carpet manufacturer’s requirements
rather than choosing by thickness alone.
Laminate Flooring Underlay
Most laminate flooring requires
a compatible underlay unless the
selected product includes an
approved attached backing.
Underlay requirements can differ by
laminate construction and locking
system. Therefore, always check
the manufacturer’s installation guide.
Engineered Timber Underlay
Suitable floating engineered timber
generally requires a compatible
underlay beneath the boards.
Direct-stick engineered timber,
by contrast, uses an approved
adhesive system rather than
traditional floating-floor underlay.
Does Hybrid Flooring Need Extra Underlay?
Many hybrid flooring products already
include attached acoustic backing.
Adding a separate underlay without
manufacturer approval can affect
the performance of the locking system.
For this reason, never assume additional
underlay is suitable simply because
a room needs more acoustic insulation.
Acoustic Flooring Underlay
Acoustic underlay can help reduce
impact noise transmitted through
a suitable flooring system.
However, acoustic results depend
on the floor covering, underlay,
substrate and installation method
tested together.
Always review the relevant test
report when an apartment or
commercial project has specific
acoustic requirements.
Underlay for Apartments
Apartment buildings may have acoustic
requirements set by the owners
corporation or building documentation.
Some projects specify a maximum
weighted impact sound level,
such as an LnTw value.
A lower LnTw result indicates better
impact sound insulation under the
relevant test conditions.
However, results from different floor
systems cannot always be compared directly.
Check that the test data reflects
the proposed flooring, underlay
and structural floor arrangement.
Rubber Flooring Underlay
Rubber underlay is available for
selected acoustic and flooring
applications. Its performance
depends on material composition,
thickness, density and intended use.
Not every rubber underlay suits
every flooring system.
Check both underlay and flooring
manufacturer requirements.
What Underlay Thickness Should I Choose?
Underlay comes in different thicknesses,
but the thickest option is not
necessarily the most suitable.
Carpet and floating hard floors
need different levels of support.
Too much movement beneath a click-lock
floor may affect its performance.
Compare thickness together with
density, compression resistance
and product compatibility.
Can Underlay Fix an Uneven Subfloor?
No. Underlay is not a substitute
for proper subfloor preparation.
Significant unevenness may require
grinding, patching or levelling
before installation.
Always assess the subfloor against
the flooring manufacturer’s
flatness requirements.
Can Underlay Be Installed Over Concrete?
Suitable underlay can be used over
concrete when the complete flooring
system allows it.
However, the substrate must meet
the applicable moisture, flatness
and surface requirements.
Some flooring systems also require
a specific moisture barrier
or moisture-management treatment.
Underlay vs Moisture Barrier
An acoustic underlay and a moisture
barrier do not necessarily perform
the same function.
Some underlay systems include
an approved moisture-control layer.
Others require an additional
compatible product.
Always follow the flooring and
underlay manufacturer’s instructions
when choosing a moisture-control system.
Choosing Underlay for Your Flooring
Start by confirming the exact flooring
product and installation method.
Then consider the subfloor and
any acoustic or moisture requirements.
- Confirm the flooring type and brand.
- Check the approved installation method.
- Review underlay thickness and density.
- Check acoustic test data where required.
- Assess subfloor flatness and moisture.
- Confirm manufacturer compatibility.
- Review warranty and installation conditions.

Flooring Underlay for Melbourne Homes
Choosing the right flooring underlay is an important part of installation. Different products provide different levels of support, comfort and acoustic performance.
At Dex Flooring, we help customers compare underlay requirements for carpet flooring , laminate flooring and engineered timber flooring .
Carpet Underlay & Floating-Floor Underlay
Carpet underlay can improve comfort and support beneath suitable carpet. Meanwhile, floating-floor underlay must provide the support required by the selected hard-floor system.
These products are not interchangeable. Therefore, compare the manufacturer's requirements before choosing an underlay material or thickness.
Acoustic Underlay for Melbourne Apartments
Acoustic performance is especially important in multi-storey buildings. However, an underlay's performance depends on the tested flooring system, not just the product itself.
Before installation, review any owners corporation requirements and the relevant acoustic test reports.
