Thermal insulation and fire safety
Rockwool sandwich panels provide effective thermal insulation while offering enhanced fire protection, meeting the strict standards required for public buildings.
Noise reduction
Rockwool sandwich panels are effective in reducing noise transmission, creating a quieter and more comfortable living or working environment. The mineral wool core acts as a sound barrier, absorbing and dampening noise vibrations from outside sources, such as traffic or construction activities.
Lightweight and easy to install
The rockwool sandwich panel is lightweight and easy to install. This makes it a popular choice for construction projects, as it is quick and convenient to install. The lightweight nature of the panel also means that it is easier to transport and handle than other insulating materials.
Low maintenance and long service life
Rockwool sandwich panel is a low maintenance and long life material. It is pest resistant and can be easily cleaned with a damp cloth if necessary. This makes it a popular choice for industrial, commercial and residential buildings.
Environmental benefits
The rockwool sandwich panel also has several environmental benefits. It is manufactured from natural materials, such as basalt rock and steel, which are abundant and easy to produce. Rock wool insulation also helps reduce energy consumption by keeping heat inside buildings and preventing it from escaping to the outside. This can help reduce greenhouse gas emissions and lower energy costs.
Application of rockwool sandwich panel
Class A Fire Safety
Natural rock wool core is non-combustible. It blocks flame spread, meeting strict fire codes for food factories, cleanrooms and warehouses.
Reliable Thermal & Acoustic Insulation
Core density 80–120kg/m³. Available thickness 50–200mm, stable heat preservation and noise reduction, saving energy for HVAC systems.
Customized Solutions & PU Edge Option
We offer RAL / custom colors, matching corner trims and PU sealed edge panels. PU edge improves air tightness, dust and moisture resistance.
Full-Service Export Support
Integrated R&D, manufacturing, technical consultation and export. We have delivered projects to Thailand, Philippines, Peru, New Zealand and more. Pre-fabricated panels enable fast installation to shorten construction time.
Maintenance of rockwool sandwich panels
Fire Performance Advantages
Class A non-combustible core: Rockwool is made of natural mineral, it will not burn or release toxic smoke when fire occurs. It can slow down flame spread and protect the whole building.
High melting point rock wool fiber maintains structural integrity under high temperature, avoiding sudden collapse of wall system.
Installation Advantages
Pre-fabricated sandwich panels, ready for direct assembly on site. Fast installation saves construction labor and time.
PU edge sealed design enables tight panel joint connection, reduces gaps, prevents dust & moisture penetration.
Custom panel sizes and matching corner trims (like orange corner boards for Thailand food factory) fit different building layouts.
Rockwool sandwich panel manufacturing process
The development of rockwool sandwich panels requires a meticulous process to ensure their superior quality and durability.
First, raw ingredients such as basalt rock and coke are heated to molten temperatures. The molten material is then spun into fine fibers to make rockwool material. It is then mixed with a binder and compressed into boards of the desired thickness. The boards are then sandwiched between two layers of metal or other materials, forming the sandwich configuration. This is ensured with an adhesive or by thermal bonding, which guarantees that the panels are strongly adherent and have excellent structural stability. The panels are then cured to strengthen the bond between the layers, which can be accomplished by applying heat or allowing the adhesive to harden over time. Once cured, the boards are cut and sized to the desired size and shape.
In addition, the rockwool sandwich panel can undergo additional treatments, such as coatings or laminations, to improve its performance and provide additional protection against moisture, fire and corrosion. Finally, the finished panels are inspected and packed for distribution. In summary, rockwool sandwich panel construction employs advanced technology and quality materials to produce a reliable and versatile building material. The meticulous steps involved in its manufacture guarantee superior quality and its application in insulation, soundproofing and fire resistance.
Sandwich panels are very versatile insulation systems, consisting of two sheets, usually made of metal, between which there is an insulating core. The characteristics and performance of sandwich panels will therefore be determined by the type of material they contain inside.
PUR (Polyurethane)/PIR (Polyisocyanurate) sandwich panel characteristics
Panels with a rigid PUR/PIR insulation core have a very low thermal conductivity. They are also lightweight and have an excellent strength to weight ratio.
Their core is made up of a foam resulting from the reaction of isocyanate and polyol, a mixture to which other additives are added to form the properties of the final foam or insulating core... This results in a single product of great insulating value.
The main difference between insulation cores (PUR and PIR) is that the foam obtained with PIR systems (Polyisocyanurate) contains a high degree of aromaticity due to the formation of the polyisocyanurate structure, providing greater thermal stability compared to urethane groups (PUR), thus improving its resistance and reaction to fire.
Characteristics of the rock wool sandwich panel
The core of the rock wool sandwich panel is also adhered to the two metal sheets by means of an adhesive. This adhesive is usually polyurethane-based, and the binders used to join the fibres to form rigid panels, including the paint or lacquer of the sheet, are also usually polyurethane-based.
Rock wool, a fibrous material made from volcanic rocks and different minerals, is a medium thermal insulation and a great acoustic insulation, with a good reaction to fire.
When to use polyurethane sandwich panel and when to choose rock wool
The polyurethane sandwich panel has a lower thermal conductivity than rock wool, so insulation values are achieved with less thickness. It is the most commonly used option in buildings and installations with high thermal efficiency requirements, such as the refrigeration industry.
The rock wool panel is usually used for sectorization. Although there are already PIR panels on the market with excellent fire resistance performance.
In addition, polyurethane panels are much lighter in weight than rock wool panels and require more technical means for transportation and installation.
