Yuav Ua Li Cas Cov Khoom Siv Rwb Thaiv Hluav Taws Uas Tsis Muaj Hnyav Txhim Kho Kev Ua Haujlwm Thermal, Acoustic thiab Hluav Taws hauv Chaw Nres Tsheb Ciav Hlau thiab Tshav Dav Hlau

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.

Cov muaj xws li:

• 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 melamine ua npuas ncauj 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.

1. 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.

Ncua

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
• rwb thaiv tsev
• ceiling thermal management
• Kev ua haujlwm ntawm HVAC
• building energy performance

2. Why Large Open Buildings Are More Prone to Heat Accumulation

Railway stations and airports often share several architectural characteristics:

• qab nthab siab
• 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.

The process typically looks like this:

Roof Heat Gain
Ncua
Heat Accumulation in Upper Space
Ncua
Higher Indoor Thermal Load
Ncua
Greater Cooling Demand

This makes roofs, suspended ceilings and skylight-adjacent areas important zones for thermal management.

3. Challenges of Traditional Insulation Materials in Transportation Buildings

Common insulation and acoustic materials include:

• iav ntaub plaub
• pob zeb wool
• polyurethane ua npuas ncauj
• 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.

For railway stations, airports and metro infrastructure, material selection is rarely based on thermal conductivity alone.

Engineers usually need to consider:

• hnyav
• hluav taws kev ua haujlwm
• acoustic kev ua tau zoo
• VOC emissions
• kub tsis kam
• txoj kev teeb tsa
• txij nkawm
• ya raws raug

4. 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 melamine ua npuas ncauj 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
• suspension systems
• supporting components

Easier Elevated Installation

Lightweight materials are generally easier to:

• thauj
• txiav
• txoj hauj lwm
• 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:

• tej
• lamination
• thermoforming
• custom shaping
• surface facing
• nplaum thaub qab

This allows it to adapt to complex architectural and equipment structures.

5. 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:

• hlau vov tsev
• 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.

• limiting downward heat flow
• helping reduce cooling load
• 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:

Melamine foam is more suitable for:

• opaque perimeter zones
• edge insulation
• ceiling-integrated insulation
• localized thermal management around skylight structures

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias:

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:

• Low-E iav
• 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
• perforated txhuas vaj huam sib luag
• 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
• Suab nrov ntawm HVAC
• suab nrov ntawm kiv cua
• 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:

SINOYQX Melamine Foam Acoustic Layer

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
• cov tshuab dej txias
• huab cua tuav units
• cov tshuab cua

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
• huab cua tuav units
• equipment housing

Material selection should be based on:

• qhov ceev ntawm huab cua
• kev khiav hauj lwm kub
• ambient humidity
• condensation txaus ntshai
• surface protection requirements
• hluav taws cov qauv
• cov kev cai tu cev

6. Equipment Rooms Are Another Important Application Area

Large transportation buildings contain many mechanical and electrical rooms, including:

• fan rooms
• chav hluav taws xob
• Chav UPS
• tswj chav
• air conditioning plant rooms
• pump rooms
• communications rooms
• electrical equipment spaces

These areas often face three problems simultaneously:

• suab nrov
• Thaum tshav kub kub
• hluav taws kev nyab xeeb

Traditional systems may require multiple layers of:

Thermal Insulation
+
Acoustic Material
+
Kev tiv thaiv hluav taws

A lightweight multifunctional material can help simplify this structure.

In certain equipment-room and enclosure applications, melamine foam may help provide:

• thermal rwb thaiv tsev
• suab haum
• reverberation reduction
• txo suab nrov kis tau tus mob

This is one of the key reasons multifunctional materials are becoming more relevant in infrastructure projects.

7. 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:

• thermal rwb thaiv tsev
• acoustic nqus
• hluav taws kev ua haujlwm
• hnav siv

it may help reduce:

• the number of material layers
• total system weight
• installation cov kauj ruam
• interface complexity
• kev tsim kho nyuaj
• 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.

8. 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
• HVAC cov tshuab
• tsheb thauj mus los
• tsheb
• aviation
• cov khoom siv enclosures

where weight reduction is important.

8.2 Tsawg 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:

• cov tshuab cua
• Cov khoom siv HVAC
• chav khoom siv
• large interior spaces
• tsheb thauj mus los
• silencers

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:

• pej xeem vaj tse
• railway systems
• tsheb
• aviation
• equipment spaces

where fire behavior is an important design consideration.

8.6 Suitable for Low-VOC Applications

Modern transportation buildings increasingly pay attention to:

• VOC emissions
• ntxhiab
• aldehyde and ketone emissions
• huab cua zoo nyob sab hauv tsev
• kev ua raws li ib puag ncig

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.

9. Standard or Hydrophobic Grade: Which Should Be Used?

Moisture conditions vary significantly across transportation infrastructure.

Standard Melamine Ua Npuas Ncauj

Hydrophobic treatment can help reduce water absorption tendency.

Txawm li cas los xij, cov engineers tseem yuav tsum soj ntsuam:

• hws
• long-term humidity
• direct water exposure
• cua
• txoj kev tu
• fixing system

before final material selection.

10. Recommended Application Matrix for Railway Stations and Airports

11. Why Transportation Infrastructure Is Driving the Shift Toward Greener Materials

Transportation infrastructure is a long-life asset.

Railway stations, airports and metro facilities are expected to operate for many years.

For this reason, material selection should not be based only on initial purchase price.

A more complete evaluation should consider life-cycle performance, including:

• thawj cov khoom siv nqi
• installation nqi
• structural loading
• HVAC energy consumption
• tus nqi kho mob
• hluav taws kev pheej hmoo
• kev pab lub neej
• sab hauv ib puag ncig zoo
• qhov nyuaj hloov pauv

Lightweight, multifunctional and heat-resistant materials may provide additional value when viewed from a whole-life perspective.
