Professional Oscar Iso-Mount

Soundproof Ceiling Installation by Arthur Acoustic

​

Arthur Acoustic specialises in the professional installation of premium acoustic management solutions across the United Kingdom. We supply and install the class-leading Oscar Iso-Mount Soundproof Ceiling System, engineered by Oscar Acoustics. This high-performance system creates an isolated, floating ceiling structure that stops structural vibrations and blocks unwanted noise transfer between floors. Whether you need to eliminate heavy footsteps, muffled voices, or loud music from neighbours above, our specialised team delivers a flawless, flat, and regulation-compliant finish.

 

 

The Benefits of the Oscar Iso-Mount Ceiling System

​

• Maximum Space Preservation: The system limits ceiling height loss to as little as 5mm to 6mm, keeping your rooms feeling spacious.

• No Overhead Disruption: We complete all acoustic installation work entirely from the room below, eliminating any need to access the property above.

• Unequalled Noise Reduction: The engineered rubber isolation blocks break the direct path of impact and airborne sound waves.

• Perfect Architectural Finish: The system levels out uneven timber joists, leaving a completely flat surface that looks like a standard plastered ceiling.

• Certified Fire Safety: The system delivers a robust, independently verified fire resistance rating of up to 90 minutes.

• Enhanced Thermal Performance: Combining the mounts with mineral wool insulation traps heat and lowers your domestic energy bills.

 

 

Why Isolate Your Ceiling with Arthur Acoustic?

​

Standard rigid ceilings act like giant drums, amplifying the impact of footsteps, dropped objects, and low-frequency bass from the room above. Conventional resilient bars often lack sufficient isolation and can easily fail if short-circuited by incorrect screw lengths during plasterboard fixing.

The Oscar Iso-Mount Hanger Range resolves this vulnerability entirely. By decoupling the new plasterboard ceiling from the building structure using resilient rubber dampers, the vibration pathway is permanently severed. Our professional installation team ensures that every component is perfectly isolated from the surrounding walls using high-density acoustic perimeter foam, preventing flanking noise transmission.

 

 

Versatile Options for Every Property Type

​

Every building structure requires a tailored technical approach. We install the two primary variations of the Iso-Mount range depending on your property's specific architectural layout:

 

Oscar Iso-Mount Type 1

This option is designed specifically for exposed timber joists in residential houses, flat conversions, and refurbishments. The hangers fix directly to the sides of the structural timber, adjusting vertically to correct uneven joists whilst losing mere millimetres of headroom.

 

Oscar Iso-Mount Type 2

This variation is ideal for existing concrete ceilings, commercial spaces, and listed buildings where the original plasterboard cannot be removed. Type 2 hangers mount directly underneath the existing surface with minimal fixings. They can also be integrated with specialized extensions to create deeper voids for heavy insulation and service ducts.

 

 

Proven Compliance with British Building Regulations

​

Our installations do not merely meet domestic acoustic requirements; they comfortably exceed them. The Oscar Iso-Mount System has been independently tested by the Building Research Establishment (BRE). It comfortably exceeds the rigorous requirements of Approved Document E of the British Building Regulations for both airborne and impact sound insulation.

 

Performance Metric | Building Regulations Document E | Oscar Iso-Mount Performance

​

Airborne Sound (Minimum) | 43 dB \(D_{nT,w} + C_{tr}\) | Exceeds Requirements

​

Impact Sound (Maximum) | 64 dB \(L'_{nT,w}\) | Exceeds Requirements

​

Fire Resistance (Tested Configuration) | Standard Residential Level | Up to 90 Minutes

​

Maximum Safe Load Capacity | Variable | 18kg per individual mount

 

 

Our Professional Installation Process

​

1. Site Inspection: We assess the ceiling layout, trace service lines, and locate the lowest structural points.

2. Structural Preparation: For Type 1 setups, we expose the timber joists and seal all subfloor gaps with acoustic sealant.

3. Precision Mounting: We anchor the genuine Oscar Iso-Mount brackets at calculated intervals using a maximum spacing matrix.

4. Channel Framework: We secure industry-standard steel C-channels into the rubber-insulated acoustic clips.

5. Void Insulation: We pack the open cavity with high-density mineral wool insulation to maximize dampening performance.

6. Perimeter Isolation: We apply self-adhesive acoustic foam around the perimeter walls to isolate the new floating frame.

7. Dual-Layer Plasterboard: We install two layers of dense acoustic plasterboard, offsetting the joints to eliminate air gaps.

8. Acoustic Sealing: We seal all outer perimeter joints with specialist acoustic sealant prior to final plaster skimming.

 

If you want to discuss your soundproofing requirements, let us know:

​

• Is your property a house, flat conversion, or commercial premises?

• Is the underlying ceiling structure made of timber joists or solid concrete?

• Are you looking to stop impact noise (footsteps) or airborne noise (voices/television)?

​

We will provide a definitive, high-performance acoustic plan tailored to your property.
