What material can provide both lightweight insulation and sound absorption for railway stations and airports? Melamine foam is a lightweight open-cell material that can provide both thermal insulation and acoustic absorption, while also offering strong heat resistance and fire-performance potential. In large transportation buildings such as railway stations and airports, it can be considered for: • roofs • suspended ceilings • HVAC ducts • equipment rooms • fan systems • acoustic enclosures • thermal protection structures Final design should always consider fire, moisture, mechanical and structural requirements.
Modern railway stations, airport terminals and major transportation hubs are becoming larger, more open and more architecturally transparent.
Large glass curtain walls, skylights, high-ceiling halls, long-span metal roofs and complex HVAC systems improve daylighting and spatial experience, but they also create new engineering challenges.
Tsena li akarelletsa:
- increased indoor heat load during summer
- high cooling demand in large-volume spaces
- heat transfer and cooling losses through roofs and HVAC systems
- continuous noise from fans, air handling units and equipment rooms
- strict fire safety and smoke performance requirements
- pressure to minimize additional structural weight
- higher expectations for cleanliness, durability and ease of installation
As a result, transportation infrastructure is moving beyond the use of single-purpose insulation materials.
The market is increasingly looking for integrated solutions that combine:
Thermal Management + Acoustic Control + Fire Safety
SINOYQX is developing high-performance foam ea melamine and composite insulation materials for railway stations, airports, metro systems and other large public infrastructure projects where lightweight construction, thermal efficiency and acoustic comfort are all important.

- Why Thermal Management Matters in Railway Stations and Airports
Large Glass Areas Increase Solar Heat Gain
Many modern railway stations and airport terminals use:
- large glass curtain walls
- glass skylights
- transparent or semi-transparent roof structures
- wide open interior spaces
These designs improve daylighting and create a more open environment.
However, under strong summer solar radiation, significant heat can enter through the building envelope.

Energy Consumption Rises
For large transportation buildings covering tens of thousands of square meters, even a moderate increase in heat gain per square meter can result in substantial additional cooling demand.
This is why modern transportation buildings increasingly focus on:
- solar heat control
- ho kwahela marulelo
- ceiling thermal management
- HVAC e sebetsang hantle
- building energy performance
- Why Large Open Buildings Are More Prone to Heat Accumulation
Railway stations and airports often share several architectural characteristics:
- siling e phahameng
- large indoor volume
- fluctuating passenger density
- frequently opening entrances
- extensive glazing
- very large roof areas
Because warm air rises, heat often accumulates near the upper sections of large halls.
If the roof is also exposed to strong solar radiation, the effect can become even more significant.

This makes roofs, suspended ceilings and skylight-adjacent areas important zones for thermal management.
- Challenges of Traditional Insulation Materials in Transportation Buildings
Common insulation and acoustic materials include:
- boea ba khalase
- boya ba lefika
- foam ea polyurethane
- elastomeric foam
- polyester fiber materials
- other porous insulation products
Each material has established applications, but large transportation infrastructure projects often require a broader performance balance.
| lintho tse bonahalang | Melemo e Tloaelehileng | Potential Engineering Challenges |
| Boea ba khalase | Mature insulation performance, competitive cost | Fiber handling, dust, installation protection |
| Boea ba lefika | Strong fire performance | Higher density, heavier weight, fabrication dust |
| Foam ea kettle | Insulation e ntle ea mocheso | Fire performance varies significantly by formulation |
| Elastomeric foam | Flexible and suitable for piping | Temperature and fire performance depend on grade |
| Polyester fiber | Good acoustic performance and processability | Fire and temperature performance depend on material system |
| Foam ea melamine | Lightweight, acoustic, thermal and fire performance | Requires application-specific structural design |
For railway stations, airports and metro infrastructure, material selection is rarely based on thermal conductivity alone.
Engineers usually need to consider:
- boima ba 'mele
- tshebetso ya mollo
- tshebetso acoustic
- tlhahiso ea VOC
- ho hanyetsa mocheso
- mokhoa oa ho kenya
- tlhokomelo
- kgahlamelo ya mongobo
- Why Lightweight Materials Matter in Transportation Infrastructure
Transportation buildings commonly use:
- long-span steel structures
- metal roofing systems
- large suspended ceilings
- complex mechanical systems
- elevated equipment installations
Reducing non-structural dead load can therefore provide meaningful engineering benefits.
SINOYQX foam ea melamine can be supplied in lightweight grades of approximately 4–12 kg/m³, depending on the required mechanical properties, processing method and application conditions.
Compared with many traditional fibrous insulation systems, melamine foam can significantly reduce material weight per unit volume.
This can provide several practical benefits.
Reduced Ceiling and Roof Load
In projects covering thousands or tens of thousands of square meters, relatively small differences in material density can create large differences in total system weight.
Lower material weight can help reduce additional loading on:
- roof structures
- ceiling frames
- litsamaiso tsa ho fanyeha
- supporting components
Easier Elevated Installation
Lightweight materials are generally easier to:
- dipalangwang
- sehiloeng
- boemo ba
- install overhead
- adapt to complex spaces
This can simplify work in large terminal buildings and high-ceiling spaces.
Better Adaptability to Complex Shapes
Melamine foam can be processed through:
- ho khaola
- ho hlatsoa
- thermoforming
- custom shaping
- surface facing
- tshehetso ya sekgomaretsi
This allows it to adapt to complex architectural and equipment structures.
- Where Can SINOYQX Melamine Foam Be Used in Railway Stations and Airports?
SINOYQX does not position melamine foam only as an acoustic foam.
A more complete role is:
A Lightweight Thermal and Acoustic Material for Transportation Infrastructure
Key applications include the following.
5.1 Roof Thermal Insulation
Large transportation buildings often have extensive roof areas.
Common roof structures include:
- ho rulela ka tšepe
- composite roof systems
- glass skylight areas
- long-span steel roofs
Melamine foam can be integrated as a lightweight thermal layer within the roof or ceiling system.

- improving acoustic comfort beneath the roof
- reducing some equipment and airflow noise
For transportation buildings, this dual thermal and acoustic function can be particularly valuable.
5.2 Auxiliary Insulation Around Glass Skylights
Glass skylights are widely used in modern transportation buildings because they improve natural lighting.
However, they can also increase solar heat gain during summer.
A possible auxiliary thermal management concept is:

Transparent or Semi-Transparent Supporting Structure

Sebaka sa Hare-hare
Melamine foam is more suitable for:
- opaque perimeter zones
- edge insulation
- ceiling-integrated insulation
- localized thermal management around skylight structures
Ho bohlokoa ho hlokomela hore:
Melamine foam itself is not transparent.
Therefore, it should not be treated as a transparent glazing insulation material.
Where daylight transmission must be maintained, the building envelope may need to combine:
- Khalase e tlase-E
- shading systems
- air gaps
- transparent insulation films
- localized opaque insulation zones
as part of an integrated thermal design.
5.3 Thermal and Acoustic Treatment Behind Suspended Ceilings
Airports and railway stations commonly use:
- metal ceilings
- liphanele tsa aluminium tse nang le masoba
- decorative ceiling systems
- acoustic ceiling assemblies
When open-cell acoustic materials are installed behind perforated panels, they can help control:
- public announcement reverberation
- crowd noise
- baggage system noise
- Lerata la HVAC
- lerata la fene
- equipment noise
The open-cell structure of melamine foam allows sound energy to enter the material and dissipate through internal friction and pore interaction.
A typical configuration may be:

Air Cavity or Structural Layer
Because melamine foam also has low thermal conductivity, the same assembly can potentially provide both:
Acoustic Absorption + Thermal Insulation
This is especially relevant in large high-ceiling spaces.
5.4 HVAC Duct Thermal and Acoustic Control
HVAC ducting is one of the most realistic application areas for multifunctional insulation materials.
Large railway stations and airports contain extensive networks of:
- supply air ducts
- return air ducts
- fresh air systems
- tsamaiso ea metsi a pholileng
- diyuniti tsa ho tshwara moya
- litsamaiso tsa fan
These systems typically face two key challenges.
Thermal Loss
Air can gain or lose heat over long transport distances, reducing cooling efficiency.
Noise Transmission
Fan noise, airflow noise and mechanical vibration can travel through duct systems.
For this reason, HVAC insulation materials that can provide both thermal and acoustic functions are increasingly attractive.
SINOYQX melamine foam can potentially be used in:
- external duct insulation
- internal acoustic duct lining
- silencer interiors
- fan enclosures
- diyuniti tsa ho tshwara moya
- equipment housing
Material selection should be based on:
- lebelo la ho phalla ha moya
- mocheso o sebetsang
- mongobo o phelang
- kotsi ea condensation
- surface protection requirements
- litekanyetso tsa mollo
- hygiene requirements
- Equipment Rooms Are Another Important Application Area
Large transportation buildings contain many mechanical and electrical rooms, including:
- fan rooms
- likamore tsa motlakase
- Likamore tsa UPS
- likamore tsa taolo
- air conditioning plant rooms
- pump rooms
- communications rooms
- electrical equipment spaces
These areas often face three problems simultaneously:
- lerata
- mocheso
- tšireletso ea mollo
Traditional systems may require multiple layers of:
Ho itšireletsa ka metsi
+
Acoustic Material
+
Tšireletso ea Mollo
A lightweight multifunctional material can help simplify this structure.
In certain equipment-room and enclosure applications, melamine foam may help provide:
- futhumatsa
- ho monya modumo
- reverberation reduction
- phokotso ya phetiso ya lerata
This is one of the key reasons multifunctional materials are becoming more relevant in infrastructure projects.
- Transportation Infrastructure Increasingly Needs Multifunctional Materials
Large public buildings increasingly favor materials that can perform more than one function.
If a single material can provide:
- futhumatsa
- ho monya ha acoustic
- tshebetso ya mollo
- kaho e bobebe
it may help reduce:
- the number of material layers
- total system weight
- mehato ea ho kenya
- interface complexity
- bothata ba ho haha
- long-term maintenance complexity
This multifunctional approach is one of the main reasons melamine foam can be considered alongside more traditional single-purpose insulation materials.
- Core Performance Advantages of SINOYQX Melamine Foam
8.1 Extremely Lightweight
SINOYQX can provide melamine foam grades in the approximate range of 4–12 kg/m³, depending on project requirements.
This makes the material particularly suitable for:
- long-span roofs
- suspended ceilings
- Litsamaiso tsa HVAC
- lipalangoang tsa terene
- likoloi tsa
- tsamaiso ea lifofane
- lisebelisoa tse koaletsoeng
where weight reduction is important.
8.2 Low Thermal Conductivity
Low-density melamine foam provides relatively low thermal conductivity.
Depending on density, temperature and test conditions, typical grades can achieve approximately:
0.032–0.035 W/(m·K)
Actual engineering values should always be confirmed according to the specific product grade, test method and operating temperature.
8.3 Strong Acoustic Absorption
Melamine foam has a three-dimensional open-cell structure.
When sound waves enter the material, acoustic energy is dissipated through:
- air friction
- pore-wall interaction
- internal sound energy loss
This makes the material suitable for:
- litsamaiso tsa fan
- Lisebelisoa tsa HVAC
- likamore tsa lisebelisoa
- large interior spaces
- likoloi tsa lipalangoang
- mebutlisoa
and other noise-control applications.
8.4 Good Fire Performance
Melamine foam has inherently favorable heat resistance and flame-retardant characteristics.
SINOYQX can provide product grades and supporting test data according to different project requirements.
Depending on the application, evaluation may include standards such as:
- UL94
- FMVSS 302
- railway fire standards
- building fire standards
- smoke density requirements
- toxicity requirements
Different countries and projects may require different test methods and compliance standards.
Therefore, fire performance should always be confirmed for the exact product grade and project specification.
8.5 No Typical Molten Dripping Behavior
Unlike some thermoplastic foams, melamine foam does not typically behave as a melt-dripping material under high-temperature exposure.
This can be particularly relevant in:
- meaho ya setjhaba
- tsamaiso ea literene
- likoloi tsa
- tsamaiso ea lifofane
- equipment spaces
where fire behavior is an important design consideration.
8.6 Suitable for Low-VOC Applications
Modern transportation buildings increasingly pay attention to:
- tlhahiso ea VOC
- monko
- aldehyde and ketone emissions
- boleng ba moya wa ka tlung
- ho latela tikoloho
As a result, material selection increasingly considers not only fire performance but also indoor environmental quality.
SINOYQX can provide material and testing support according to project requirements.

- non-transparent sections
- ceiling cavities
- auxiliary insulation layers
Where daylight transmission must be preserved, the design should combine other solutions such as Low-E glass, shading systems or transparent insulation technologies.
Can melamine foam replace glass wool?
In some applications, yes, but the materials are not identical.
They differ in:
- ditjeho
- bongata ba tsona
- tshebetso acoustic
- moisture behavior
- tshebetso ya mollo
- mokhoa oa ho kenya
Therefore, replacement should be evaluated on a project-specific basis.
Is melamine foam suitable for HVAC ducts?
It can be suitable for many HVAC thermal and acoustic applications.
The selected grade should be evaluated according to:
- lebelo la ho phalla ha moya
- mocheso
- mongobo
- kalafo holim
- hygiene requirements
- litekanyetso tsa mollo
- kotsi ea condensation
What is the main advantage of melamine foam?
