`Rockwool Sandwich Panels for Steel Structures | Fireproof Insulated Panels`

We manufacture rock wool sandwich panels that are ideal for both commercial and industrial construction. The panels have a high-density rock wool core, with metal facing that gives them a good level of fire resistance, thermal insulation, and structural performance.

Rockwool Sandwich Panels & Advantages

Our fire-resistant sandwich panels have achieved a Class A fire rating, effectively blocking the spread of flames and ensuring maximum safety in high-risk environments.
Exceptional Thermal Insulation: The core material of high-quality mineral wool sandwich panels features extremely low thermal conductivity, contributing to stable indoor temperatures.
Robust Construction: Features a corrosion-resistant steel finish, ensuring a long service life, weather resistance, and structural integrity.
Rapid Installation: The design of the lightweight sandwich wall panels enables rapid on-site assembly, thereby saving on labor costs and construction time.
The structure is robust, possesses strong seismic resistance, and offers excellent thermal insulation performance.

Types of Rockwool Sandwich Panels We Supply

We offer custom size rockwool sandwich panels to fit different project needs—no matter the scale of your steel warehouse or industrial building:

Roof Rockwool Sandwich Panels：These products were designed for steep roofs and have excellent water-resistance and wind-load bearing capacity (good for cold climates like Canada and Russia) and provide inherent fire protection, as well as sound insulating capabilities, to industrial roofing applications.
Wall Rockwool Sandwich Panels:Steel warehouse and workshop walls (both outside and inside) have either a smooth surface with no need for decorative materials. The walls provide excellent fire protection for office partitions and production rooms.
Fire-Rated Rockwool Sandwich Panels:Standard Class A fire-rated projects, at the top tier of fire safety standards, have the highest degree of fire safety requirements.

FAQ About Rockwool Sandwich Panels

Q：How is the thermal insulation performance of rockwool panels?

A：High density mineral wool core is extremely nonconductive to heat or cold – therefore it is an excellent insulator against temperature. With this good insulation, your buildings will stay at a comfortable temperature all year long and reduce the costs of keeping them cool in the summer and warm in the winter.

Q：How long do rockwool sandwich panels last?

A：Our panels have an estimated lifespan of 25-30 years (under normal usage and appropriate maintenance) because of corrosion resistant colored steel facings as well as a non-degradable rock wool core. In addition, our panels will not be affected by UV rays or by moisture or any severe weather conditions.

Q：Are rockwool panels easy to install?

A：Yes. Our prefabricated rockwool panels provide a lightweight interlocking design for fast onsite construction (i.e. assembly of multiple panels on the job site). These panels can reduce your construction period substantially and reduce labour costs as compared to traditional construction materials.

Q：Can you provide custom sizes and specifications?

A：Yes, our company offers full customization in the core thickness and steel plate thickness, as well as the color and length of panels to suit your specific needs for any building project.
