Why Choose Rock Wool Wall Panels for Your Building Envelope?
Aislamiento térmico
With low thermal conductivity, our rock wool wall panels mitigate indoor-outdoor heat transfer. Buildings enclosed with high-density rock wool experience reduced operational costs.
Class A1 Fire Safety
The rock wool wall panels's core material is completely non-combustible. It can withstand high temperatures and maintain structural integrity.
Absorción acústica
The rock wool within the rock wool wall panels consists of a porous fibrous matrix that effectively blocks sound waves, thereby reducing reverberation in high-noise work areas.
Instalación rápida
The rock wool wall panels feature a practical connection method that helps reduce installation time and labor costs. Glostar is happy to provide sandwich panels installation services.
Vertical Installation Scheme for Rock wool Wall Panels
The vertical installation scheme for rock wool wall panels is primarily designed for tall industrial facilities and modern facades; by mounting the panels vertically onto horizontal wall girts, the design facilitates gravity-assisted rainwater runoff, thereby significantly enhancing waterproofing and airtightness. During installation, precise positioning of the base drip edge and ensuring the vertical alignment of the initial rock wool wall panel are critical; joints are sealed with weather-resistant sealant and secured using concealed fasteners or self-tapping screws, a method that not only bolsters wind-load resistance at height and maintains Class A fire-safety integrity but also lends the building a sleek, soaring aesthetic.
Horizontal Installation Scheme for Wall Sandwich Panels
The horizontal installation scheme for rock wool wall sandwich panels is primarily utilized in modern commercial buildings and high-end industrial parks. By mounting the rock wool wall panels horizontally onto vertical columns, the design creates an aesthetic of sleek, expansive horizontal lines that visually widen the structure. Installation proceeds layer by layer from the bottom up, with critical emphasis placed on precisely verifying the horizontal alignment of the base panel. Tongue-and-groove joints are fitted with pre-applied waterproof sealing strips and integrated rain-shedding grooves; this configuration prevents water accumulation and leakage at horizontal seams while effectively distributing wind loads, thereby achieving a perfect blend of superior fire resistance, thermal insulation, and a modern architectural appearance.
Versatile Applications Across Critical Industries
Industrial Warehouses & Steel Workshops: Ideal as external facade cladding and interior division walls where fire compliance is enforced by local building codes.
Pharmaceutical & Electronics Cleanrooms: Used for non-dusting, highly sterile wall partitions requiring frequent chemical washdowns and tight environmental controls.
Power Plants, Data Centers & Generator Rooms: Installed as acoustic barriers and firebreak walls to isolate high-risk equipment and suppress excessive operational noise.
Commercial Logistics Parks: Applied in large-scale logistics hubs seeking rapid modular construction, thermal stability, and long-term envelope durability.

Our rock wool wall panels achieve a Class A1 non-combustible rating according to international fire test standards (EN 13501-1). Depending on thickness and structural configuration, they provide 1 to 4 hours of fire resistance.
Polyurethane edge sealing closes the porous sides of the rock wool. This prevents water vapor penetration during rain or cleaning, enhances airtightness, and increases the structural strength at the rock wool wall panel joints by up to 30%.
Yes. They are widely used as internal fire-rated dividing walls, acoustic partition panels in factories, and smooth wall systems in cleanrooms.
PU sandwich panels generally provide better thermal insulation with a lower U-value at the same panel thickness, making them a good choice for projects where energy efficiency and temperature control are the main priorities. EPS panels, on the other hand, are lightweight and cost-effective, making them suitable for projects with moderate insulation and budget requirements.
Paneles sándwich de lana de roca offer significant advantages in fire resistance, acoustic insulation, and high-temperature performance. Their non-combustible mineral wool core makes them particularly suitable for industrial buildings, warehouses, factories, cleanrooms, workshops, and other facilities where fire safety requirements are more demanding. Rock wool also provides excellent sound absorption, helping reduce noise transmission in industrial and commercial environments.
When choosing between rock wool, EPS, and polyurethane sandwich panels, the best option depends on your project’s fire rating requirements, thermal insulation targets, acoustic performance, budget, building application, and local regulations. For projects where fire safety and acoustic performance are key considerations, rock wool sandwich panels are often the preferred solution.
