Difference between sandwich panel materials Core

There is no single sandwich panel core that is best for every project. Rock wool, PIR/PU, EPS and glass fiber panels solve different problems. The right choice depends on the building application, fire-safety requirement, insulation priority, acoustic needs, humidity exposure, budget and installation conditions.

PIR / PU Sandwich Panel

PU PUF(Polyurethane Foam) Sandwich Panel is applied evenly through the foaming agent formula to color steel, forming an excellent three-layer fire prevention board.
New lightweight building materials, color steel, and polyurethane combination, the main fire-retardant and high-temperature resistance, self-extinguishing after adding fire retardant.
The softening point is more than 250℃ and decomposed under high temperatures. When burning, the surface accumulates carbon, isolates the foam, and fire spreads.

Rock Wool Sandwich Panel

Rock Wool Sandwich Panel has low density, reducing the dead weight of the building and improving safety.
With an excellent sound insulation effect, it is the ideal sound-absorbing and soundproof material.
High fire performance, non-combustible, and does not release harmful gases to protect the safety of life and property.

Glass Fiber Sandwich Panel

Glass Fiber Sandwich Panel is energy-saving and environmentally friendly, with no formaldehyde and a wind pressure prevention design to enhance stability. It has low cost and high efficiency, diverse forms, and is beautiful, with no cold bridge. Class A flame retardant, suitable for high fireplaces; connection-fireplaces design, optimizes heat preservation and insulation. Features include thermal insulation, fire prevention, sound absorption, vibration damping, flexible construction, moisture-proof and durability, and suitable for many buildings

EPS Sandwich Panel

EPS Sandwich Panel is the abbreviation of exploitable polystyrene board. Apolystyrene foam sheet with a closed cell structure is prepared by heating the exploitable polystyrene beads in a mold after pre-foaming with heating.

Why Rock Wool Is a High-Value Core for Demanding Buildings

Rock Wool Core for Safer Building Envelopes

Tseason rock wool sandwich panels are made of metal facings and a rock wool core; the internal rock wool meets the highest A1 non-combustible rating under the European Union’s EN 13501-1 standard. Depending on the panel thickness, the fire resistance rating of the wall can range from 30 minutes to 4 hours. In addition to its excellent fire resistance rating, the thermal conductivity (λ ≤ 0.045 W/m・K) meets the energy-saving requirements of factories, helping to reduce energy loss in industrial plants, warehouses, equipment rooms, and public buildings.
Tseason does not merely sell rock wool sandwich panels; rather, we consider the actual application scenarios for project walls and roofs, pair them with the appropriate outdoor weather-resistant coating solutions, and take into account fire resistance ratings and various energy efficiency standards to precisely match customers with a complete panel system that meets all project requirements.

Better Acoustic Comfort for Industrial and Commercial Spaces

Rock wool consists of a porous structure formed by countless fine, interwoven fibers. When sound waves enter these pores, they are reflected and refracted, converting into thermal energy and resulting in energy loss, thereby achieving sound absorption and noise reduction. Tseason rock wool sandwich panels are available in a variety of thicknesses ranging from 50 mm to 150 mm and density combinations from 80 to 120 kg/m³, with STC sound insulation ratings ranging from 40 dB to over 60 dB. Models can be flexibly selected based on the intensity of the noise source.
Tseason rock wool sandwich panels combine fire resistance with a fire resistance rating exceeding 1,000°C and significant sound insulation performance, making them particularly suitable for the following applications:

Machine shops and stamping workshops: 50–75 mm / 80–100 kg/m³ specifications, STC 40–45 dB, to reduce equipment operating noise
Logistics warehouses and production workshop partitions: 100 mm / 100–120 kg/m³ specifications, STC 50–55 dB, meeting sound insulation requirements for personnel work areas
Machine rooms and recording studio-grade soundproof spaces: High-density core material of 100 mm or more, STC 60 dB or higher, suitable for electromechanical equipment rooms with stringent sound insulation requirements

Application & Solutions

Industrial and Warehouse Building Envelopes

For factories, steel-structure workshops, warehouses and logistics buildings, rock wool sandwich panels are commonly used as exterior wall cladding and roofing panels. These projects usually need large-area installation, stable panel supply and clear matching with steel frames, purlins, roof slopes and facade drawings. Buyers should confirm panel length, cover width, coating type, steel thickness and installation details before quotation so the wall and roof system can fit the project design instead of being treated as a generic panel purchase.

Public and Commercial Buildings

Public and commercial buildings such as schools, hospitals, exhibition centers, stations, shopping centers and office facilities often require wall systems that combine appearance, insulation, acoustic comfort and fire-safety consideration. In this scenario, rock wool sandwich panels are not only evaluated as insulation material, but also as part of the exterior facade or interior wall system. The purchasing focus should include surface finish, hidden fixing or facade appearance, coating durability, document availability and whether the panel system can support the building’s long-term maintenance requirements.

Cleanrooms and Controlled Production Areas

Cleanrooms and controlled production areas require enclosure panels that support hygiene control, stable interior conditions and reliable joint treatment. Rock wool panels may be reviewed when a project needs mineral wool insulation together with cleanroom wall system planning, coating selection and documentation review. This application is more suitable for pharmaceutical, electronics, food-related or precision manufacturing spaces where the buyer needs both enclosure performance and controlled indoor conditions

Equipment Rooms and Noise-Controlled Spaces

For machinery rooms, power rooms, production lines and other areas with continuous equipment noise, rock wool sandwich panels can be considered as part of an acoustic wall or partition system. The buyer should first define whether the target is sound absorption, sound insulation or general acoustic comfort, because each goal may affect panel thickness, surface design, steel facing and installation method. This direction is especially relevant for industrial buildings where noise control, worker comfort and enclosed equipment zones are part of the project requirement.

FAQs

Are rock wool sandwich panels a good choice for commercial building insulation

Yes. Rock wool sandwich panels are a strong option for commercial and industrial buildings that need insulation together with fire-safety relevance, acoustic comfort and durable wall or roof enclosure.

Can Tseason rock wool sandwich panels be used for roofing projects?

Yes. Tseason has roof-related rock wool sandwich panel content, but roof use must be reviewed as a complete system, not only as a panel core choice.Roofing projects should confirm panel profile, roof slope, purlin spacing, lap direction, fastening, flashing, waterproof details and accessories. Tseason’s roofing installation content highlights leakage prevention, buckle connection and hidden nail installation, which makes installation details critical for long-term roof performance.

What should buyers check when sourcing fire-resistant sandwich panels for industrial use?

Buyers should check whether the fire-related document matches the exact panel structure, including core material, thickness, steel facing and joint details.Tseason’s sandwich panel buying guide points out that many disputes come from certificate mismatch, misleading thermal data, steel thickness discrepancy and inconsistent batch documents. For industrial rock wool sandwich panels, the quotation, TDS, tested product structure and project drawings should be cross-checked before production or shipment.

How do I choose sandwich panels for soundproofing a warehouse or factory?

For warehouse or factory soundproofing, choose panels based on the noise source, wall or partition location, required sound absorption or sound insulation goal, and installation details.You can check our rock wool soundproof sandwich panel.

How should buyers source outdoor sandwich panels with UV protection or custom specifications?

Buyers should confirm coating type, color requirement, panel thickness, cover width, steel facing, length range and project environment before requesting outdoor or custom-sized sandwich panels.Tseason’s coating guide discusses PE, SMP and PVDF coating directions for roofing, wall cladding and industrial applications. For outdoor walls, coastal projects or high-exposure roofs, coating durability and installation details matter as much as the core material. Custom specifications should be matched with drawings and application conditions before quotation.
