Introduction: Why Vibration Control Matters in Industrial Settings
Vibration is an unavoidable byproduct of industrial machinery. From CNC machines and generators to HVAC systems and printing presses, equipment vibration creates problems that extend far beyond simple noise. Unchecked vibration damages machinery, degrades product quality, disturbs workers, and can even cause structural issues in buildings.
Anti-vibration rubber mats provide a cost-effective solution to these challenges. By isolating machinery from floors and structures, these specialised mats absorb and dissipate vibrational energy before it can cause harm. In this comprehensive guide, we examine how anti-vibration matting works, when you need it, and how to select the right solution for your specific application.
Understanding Industrial Vibration
Before selecting an anti-vibration solution, it helps to understand what youre dealing with. Industrial vibration typically falls into several categories:
Types of Machinery Vibration
Rotational vibration occurs in equipment with rotating components—motors, pumps, fans, and turbines. This vibration typically occurs at frequencies related to the rotation speed (measured in RPM or Hz).
Reciprocating vibration comes from equipment with back-and-forth motion—compressors, piston engines, and certain manufacturing equipment. This creates more complex vibration patterns.
Impact vibration results from sudden forces—stamping presses, hammers, punch presses, and similar equipment. These produce high-amplitude, short-duration vibration events.
Random vibration contains multiple frequencies without a clear pattern—often seen in fluid handling equipment, conveyors, and complex manufacturing processes.
How Vibration Causes Problems
Vibration creates issues through several mechanisms:
- Structural transmission: Vibration travels through floors and building structures, affecting distant areas
- Resonance: When vibration frequency matches a structures natural frequency, amplification occurs—potentially causing serious damage
- Fatigue: Continuous vibration weakens materials over time, leading to failures
- Airborne noise: Vibrating surfaces radiate sound energy, creating workplace noise
The Science Behind Anti-Vibration Rubber Mats
Anti-vibration mats work on fundamental physics principles. When machinery vibrates, it generates kinetic energy. Rather than allowing this energy to transfer into the floor, anti-vibration matting absorbs and dissipates it through several mechanisms:
Energy Absorption
Rubber is a viscoelastic material—it exhibits both viscous and elastic properties. When compressed by vibration, rubber deforms and then returns to shape. During this cycle, some vibrational energy converts to heat through internal molecular friction, effectively removing it from the system.
Frequency Filtering
Every isolation system has a natural frequency determined by the mass it supports and its stiffness. When vibration frequency exceeds this natural frequency by a factor of √2 (approximately 1.4), isolation begins to occur. The further above this threshold, the greater the isolation.
This is why softer, thicker mats generally provide better isolation for high-frequency vibration, while stiffer materials may be needed for low-frequency sources or heavy loads.
Impedance Mismatch
Rubber has very different acoustic properties to concrete or steel. This mismatch in acoustic impedance causes vibrational energy to reflect at the interface rather than transmit through—similar to how light reflects at a glass-air boundary.
When Do You Need Anti-Vibration Matting?
Common Applications
Manufacturing Equipment: CNC machines, lathes, milling machines, and precision equipment require vibration isolation to maintain accuracy and extend tool life. Even small vibrations can affect surface finish quality and dimensional accuracy.
HVAC Systems: Air handling units, chillers, cooling towers, and rooftop equipment transmit vibration into buildings. This creates noise complaints in occupied spaces and can damage building structures over time.
Generators and Compressors: Backup generators, air compressors, and similar rotating equipment produce significant vibration. Without isolation, this vibration travels through floors and walls, affecting entire buildings.
Printing and Packaging: High-speed printing presses and packaging machinery create vibration that affects print quality and machine longevity. Isolation improves output quality while reducing maintenance requirements.
Data Centres: Server rooms contain numerous sources of vibration—cooling systems, UPS units, and the servers themselves. Isolation protects sensitive equipment while reducing acoustic noise levels.
Gym Equipment: Commercial gym flooring beneath weights areas, treadmills, and exercise machines protects building structures and reduces noise transmission to neighbouring spaces.
Signs You Have a Vibration Problem
Consider anti-vibration solutions if you observe:
- Excessive noise from machinery or transmitted through floors/walls
- Premature bearing or component failures
- Quality issues related to machine vibration
- Complaints from workers or neighbouring occupants
- Visible movement in nearby objects or structures
- Cracks developing in floors or walls near equipment
- Difficulty calibrating precision instruments
Types of Anti-Vibration Rubber Products
Anti-Vibration Matting Sheets
Available in various thicknesses from 4mm to 25mm, these sheets can be cut to size for custom applications. Thicker options provide better isolation for higher-frequency vibration but may reduce stability for tall equipment.
Our Anti-Vibration Rubber Mat provides excellent machine isolation in thicknesses from 4mm to 12mm, suitable for a wide range of industrial applications.
Acoustic Soundproofing Rubber
For applications where airborne noise is the primary concern, acoustic rubber sheeting rated for specific sound reduction levels (up to 86dB) addresses both vibration and noise transmission simultaneously.
Ribbed Matting
The air gaps in ribbed rubber matting create additional isolation through air cushioning effects. This design also allows ventilation beneath equipment—important for motors and equipment generating heat.
Interlocking Mats
Interlocking industrial mats allow you to cover larger areas while maintaining the isolation benefits of solid rubber. These work well for protecting entire machine bays or workshop areas.
Anti-Fatigue Industrial Matting
Many industrial anti-fatigue mats provide vibration isolation benefits alongside worker comfort. These are ideal for workstations near vibrating equipment where operators stand for extended periods.
Material Considerations
Natural Rubber (NR)
Natural rubber offers excellent vibration damping properties and is suitable for most general applications. It performs well across a wide temperature range and provides good resilience. However, it has limited resistance to oils and petroleum products.
Best for: General machinery isolation, HVAC equipment, clean environments
Nitrile Rubber (NBR)
For environments with oil or fuel exposure, nitrile rubber maintains its properties where natural rubber would degrade. This makes it essential for workshops, garages, and manufacturing areas where lubricants are present.
Best for: Workshops, engineering facilities, anywhere with oil/grease exposure
EPDM Rubber
EPDM (Ethylene Propylene Diene Monomer) excels in outdoor applications and environments with ozone, UV, or weather exposure. It also handles steam and hot water well.
Best for: Outdoor equipment, rooftop HVAC, applications with steam/hot water
Recycled Rubber
Many anti-vibration products use recycled rubber—primarily from end-of-life tyres. This provides excellent performance while contributing to sustainability goals. The vulcanisation process used in tyre manufacturing creates a dense, durable material well-suited to vibration isolation.
Selecting the Right Thickness
Thickness selection involves balancing isolation performance against stability and load-bearing requirements:
Light Duty (4-6mm)
Suitable for:
- Small motors and pumps
- Office equipment (printers, servers)
- Light workshop machinery
- HVAC ductwork
Medium Duty (8-12mm)
Suitable for:
- Industrial machinery
- CNC machines and lathes
- Larger HVAC equipment
- Compressors and generators
- Printing equipment
Heavy Duty (15-25mm)
Suitable for:
- Very heavy machinery
- Impact equipment (presses, hammers)
- Large rotating equipment
- Critical isolation applications
Load Considerations
The mat must support the equipment weight without excessive compression. If the rubber compresses more than 15-20% of its original thickness, isolation performance degrades significantly. For heavy equipment, harder rubber compounds or thicker material may be needed.
Installation Best Practices
Surface Preparation
- Level the floor: Uneven surfaces cause point loading and reduce effectiveness
- Clean thoroughly: Remove oil, dust, and debris that could affect adhesion or create high spots
- Check for moisture: Trapped moisture can cause issues over time
- Consider drainage: For outdoor or wet applications, ensure water cannot pool beneath mats
Placement Considerations
- Size matters: Mat should extend at least 50mm beyond the equipment footprint on all sides
- Even loading: Ensure all mounting points contact the mat evenly
- Avoid hard bridges: Rigid connections (pipes, conduit) bypassing the isolation will transmit vibration
- Consider flexible connections: Use flexible hoses and cables where equipment connects to fixed services
Securing Methods
For most applications, the weight of equipment provides sufficient anchoring. However, some situations require additional securing:
- Adhesive fixing: For permanent installations or where movement is a concern
- Perimeter strips: Metal or rubber strips securing mat edges
- Recessed installation: Mat set into a floor recess for a flush finish
Measuring Vibration Isolation Performance
Transmissibility
The key metric for vibration isolation is transmissibility—the ratio of vibration amplitude after isolation to amplitude before. A transmissibility of 0.1 (or 10%) means 90% of vibration is being isolated.
Isolation Efficiency
Isolation efficiency is expressed as a percentage: if transmissibility is 0.1, isolation efficiency is 90%. Professional applications often target 80-95% isolation efficiency.
Decibel Reduction
For noise-focused applications, reduction is measured in decibels (dB). Our acoustic rubber products provide tested dB reduction ratings, making specification straightforward for sound control applications.
Industry-Specific Applications
Manufacturing and Engineering
Precision manufacturing requires exceptional vibration control. CNC machines, coordinate measuring machines, and similar equipment need isolation from both external sources and their own vibration.
Key considerations:
- Match isolation to machine weight and vibration frequency
- Consider isolation mounts for individual machines plus floor matting for general workshop isolation
- Dont forget ancillary equipment—coolant pumps, chip conveyors, and dust extraction create their own vibration
Building Services (HVAC)
Mechanical services are often the largest source of building vibration and noise. Proper isolation at installation prevents decades of complaints and remedial work.
Key considerations:
- Rooftop equipment needs UV-resistant materials (EPDM)
- Isolate both the unit and connecting ductwork
- Consider spring isolators for very low-frequency equipment, with rubber matting beneath for secondary isolation
Printing and Paper Processing
High-speed printing equipment creates significant vibration that affects print quality and machine longevity. Web-fed presses, in particular, require careful isolation to maintain registration and prevent web breaks.
Key considerations:
- Isolate individual print units where possible
- Consider the entire paper path—vibration affecting any roller can cause quality issues
- Oil-resistant materials are essential due to inks and lubricants
Data Centres and Server Rooms
Modern data centres contain significant vibration sources while housing sensitive electronic equipment. Proper isolation protects both the equipment and building acoustics.
Key considerations:
- Raised floor systems benefit from isolation pads at pedestal locations
- CRAC/CRAH units are often primary vibration sources
- Generator and UPS rooms require special attention
Cost-Benefit Analysis
Direct Costs
Anti-vibration matting typically costs £30-80 per square metre, depending on thickness and material specification. For a typical machine installation requiring 1-2 square metres, material costs are minimal compared to equipment value.
Avoided Costs
Proper vibration isolation provides returns through:
- Extended equipment life: Reduced vibration means less bearing wear, fewer component failures, and longer service intervals
- Improved product quality: Particularly in precision manufacturing and printing
- Reduced noise complaints: Avoiding acoustic consultants, remedial works, and potential legal issues
- Lower maintenance costs: Less time spent on vibration-related repairs and adjustments
- Worker wellbeing: Reduced noise exposure and hand-arm vibration concerns
ROI Timeline
For most industrial applications, the investment in anti-vibration matting pays for itself within 6-18 months through reduced maintenance and improved equipment longevity. Where noise complaints or quality issues are already present, the return is often immediate.
Regulations and Standards
Workplace Noise
The Control of Noise at Work Regulations 2005 set exposure limits for workplace noise. Where machinery contributes to excessive noise levels, isolation is often part of the required control measures.
- Lower exposure action value: 80 dB(A) daily exposure
- Upper exposure action value: 85 dB(A) daily exposure
- Exposure limit value: 87 dB(A) daily exposure
Vibration Exposure
The Control of Vibration at Work Regulations 2005 covers both hand-arm vibration (from handheld tools) and whole-body vibration (from vehicles or transmitted through floors). Floor-transmitted vibration from poorly isolated machinery can contribute to whole-body vibration exposure.
Building Regulations
Part E of the Building Regulations addresses sound transmission between spaces. For commercial buildings with sensitive neighbours (residential, healthcare), vibration isolation of mechanical plant is often required to achieve compliance.
Maintenance and Longevity
Expected Lifespan
Quality rubber anti-vibration matting typically lasts 15-25 years in normal service. Factors affecting longevity include:
- Load relative to material rating
- Chemical exposure
- UV exposure (for outdoor applications)
- Temperature extremes
Inspection Schedule
Annual inspection should check for:
- Excessive compression or permanent deformation
- Cracking or degradation
- Chemical attack or swelling
- Shifting or movement from original position
When to Replace
Replace anti-vibration matting when you observe:
- Permanent compression exceeding 20% of original thickness
- Cracks or splits affecting structural integrity
- Material hardening or softening indicating degradation
- Return of vibration or noise problems previously controlled
