Installation process

Our Soundproofing Installation Process

Every vehicle is carefully stripped, inspected and treated in multiple stages. Each layer targets a different source of vibration, road noise, resonance and heat.

Step 1
LandCruiser interior strip down
Preparation

Vehicle strip-down

Seats, carpets, trims, door cards and other required interior components are carefully removed to access the vehicle body.

Step 2
Vehicle floor inspection and rust treatment
Inspection

Inspection & rust treatment

The exposed body is inspected for corrosion, moisture and previous repairs. Rust treatment is carried out where required before soundproofing begins.

Step 3
Vehicle body cleaning and degreasing
Preparation

Cleaning & degreasing

Metal surfaces are thoroughly cleaned and degreased to ensure strong, long-lasting adhesion of the soundproofing materials.

Step 4
Floor vibration damping installation
Floor — Layer 1

Vibration damping

The first layer is applied across the floor and transmission tunnel to reduce metal resonance and structural vibration.

Step 5
Floor acoustic and thermal insulation layers
Floor — Layers 2 & 3

Sound & heat protection

Additional acoustic and thermal layers are installed over the floor to reduce airborne road noise, tyre noise and heat transfer.

Step 6
Inner door skin soundproofing
Doors

Inner door skin treatment

The inner metal skin is treated with vibration damping material to reduce panel resonance and improve overall door rigidity.

Step 7
Outer door skin soundproofing
Doors

Outer door skin treatment

The external door skin and accessible cavities are treated to reduce side-entry road noise, vibration and unwanted resonance.

Step 8
Roof vibration damping and thermal insulation
Roof — Layers 1 & 2

Roof sound & heat insulation

Vibration damping is applied to the large roof panels, followed by acoustic and thermal insulation beneath the headliner.

Step 9
Wheel arches side walls and rear wall soundproofing
Rear body

Wheel arches, side walls & rear wall

High-energy tyre-noise areas and large rear body panels are treated to minimise road noise, vibration and body resonance.

Step 10
Interior plastic trim soundproofing
Interior trims

Plastic trim soundproofing

Interior plastic panels and contact points are treated to minimise rattles, squeaks and unwanted trim resonance.

Step 11
Bonnet soundproofing
Bonnet soundproofing

Bonnet soundproofing

Bonnet soundproofing to minimise engine noise.

Step 12
Vehicle reassembly and final testing
Final stage

Reassembly & final testing

The vehicle is carefully reassembled and checked for correct operation, trim fitment, rattles and overall installation quality before delivery.

Typical installation time: 1–8 days. The exact installation time depends on the selected soundproofing package, vehicle body style and the areas being treated.

Installed system vs well-known material brands

Public-source basis (checked September 2026): Car Builders describes 2.0–2.2 mm butyl/aluminium Stage 1 material, 4 kg/m² MLV and 70 Series vehicle packs; SoundSkins Pro publishes a foam + butyl + aluminium composite; Dynamat Xtreme publishes 1.7 mm thickness and 0.417 loss factor at 200 Hz / 20°C. SDS numeric lab values are intentionally not invented — add verified SDS test data later if you want a defensible technical-superiority claim.

70 Series soundproofing FAQ

Questions owners usually ask before booking

Will soundproofing affect my Toyota warranty, especially on a new 70 Series?

Our soundproofing process is designed to avoid permanent modifications to the vehicle. We do not modify factory mounting points, wiring, connectors or other original components. Soundproofing materials are installed only in suitable areas and in accordance with the material manufacturer’s installation requirements. This approach helps preserve the vehicle’s original structure and systems, including on new 70 Series vehicles. Warranty coverage ultimately remains subject to Toyota’s warranty terms and the specific nature of any future warranty claim.

How quiet can my 70 Series be after soundproofing?

Every 70 Series is different, so the result depends on your vehicle, tyres, setup and the areas being treated. During our free noise assessment, we inspect your vehicle and take noise measurements. We also use a specialised noise generator attached to the vehicle to demonstrate how sound travels through different areas of the cabin. This allows us to show you the expected before-and-after difference and recommend the right soundproofing treatment before you proceed.

How long does Toyota LandCruiser 70 Series soundproofing take?

Installation time depends on the areas being treated and the overall scope of work. Most soundproofing projects take between 1 and 7 days. As a general guide, two doors take around 1 day, four doors around 2 days, the floor approximately 2–3 days, and the roof around 1–2 days. These times are estimates and may vary depending on the vehicle and selected package. Contact us for a more accurate timeframe for your 70 Series

Which 70 Series body styles can you treat?

Wagon, Single Cab, Troop Carrier and Double Cab. The material layout changes with the body structure and the areas included in your package.

Do you treat the firewall and dashboard?

They are available in an Individual build and are included only where safe access and the planned scope allow it. The final method depends on the vehicle and fitted accessories.

Can you work around drawers, touring accessories or custom interiors?

Usually yes, but access and removal time can change the scope. Send photos of the current setup when requesting a quote so the job can be planned correctly.

Why use different materials in different areas?

Vibration damping, absorption, decoupling and sound blocking do different jobs. A roof, door, firewall and wheel arch do not need exactly the same layer stack, so the system is selected by location and available clearance.

Ready to quieten your LandCruiser?

Tell us your body style and the noise you want gone first.

We’ll recommend the package and treatment zones that make sense for your 70 Series rather than loading the vehicle with unnecessary material.
