50mm/75mm/100mm/150mm/200mm Class B1 Cold Storage PIR Sandwich Panels

Features of PIR Sandwich Panels

Superior Thermal Insulation Performance:

PIR sandwich panels offer exceptional thermal insulation due to their high-density core material, which has a low thermal conductivity (typically between 0.020 and 0.024 W/(m·K)). This ensures significant energy savings and improved indoor comfort.

Enhanced Fire Resistance:

The panels achieve a fire rating of Class B1, indicating excellent fire resistance. They produce minimal smoke and do not drip when exposed to flames, helping to prevent the spread of fire and ensuring greater safety in building applications.

Excellent Dimensional Stability:

PIR sandwich panels maintain their shape and size even under varying temperature and humidity conditions, reducing issues related to expansion or contraction. This stability contributes to longer-lasting performance and durability.

High Durability and Weathering Resistance:

These panels are designed to withstand harsh environmental conditions, including UV exposure, moisture, and extreme temperatures. Their long-term stability and resistance to aging make them suitable for various climates.

Environmental Friendliness:

Modern PIR sandwich panels are produced using environmentally friendly processes and materials, often free from harmful substances like CFCs (chlorofluorocarbons). This makes them a sustainable choice for green building projects.

Lightweight yet Strong:

Despite being lightweight, PIR sandwich panels provide excellent structural strength, facilitating easier transportation and installation without compromising on performance.

Versatile Applications:

Suitable for a wide range of applications, including walls, roofs, ceilings, and partition systems in commercial, industrial, and residential buildings. They are particularly effective in cold storage facilities, cleanrooms, and other environments requiring strict temperature control.

Cost-Effective Solution:

Offering a balance of high performance and affordability, PIR sandwich panels provide an economically viable option for achieving superior insulation and fire protection in building envelope systems.

Applications

These panels are characterized by its excellent thermal insulation performance, lightweight, beautiful appearance, and quick installation, widely used in the envelope systems of both industrial and civil constructions, providing reliable thermal and fire protection.

Other FAQ

What is a PIR sandwich panel?

PIR Sandwich Panel, also known as Polyisocyanurate Sandwich Panel, is a foamed material produced by the reaction of polyisocyanurate and polyether in the presence of a catalyst. It exhibits superior physical properties and fire resistance compared to conventional polyurethane (PUR).

What is the difference between PIR and PUR sandwich panels?

In the composition of PIR panels, the concentration of flame retardants is generally lower than that in PUR panels, resulting in less smoke generation during combustion. There are even PIR panels available on the market that are free from halogen-based flame retardants.

What are the disadvantages of sandwich panels?

If the insulation material used in sandwich panels is combustible, the risk of fire can increase exponentially. In fact, fires in buildings constructed with sandwich panels made from combustible materials are often extremely difficult to extinguish, typically resulting in the complete destruction of the structure by firefighters.

Is sandwich panel fire rated?

Owing to the use of PIR foam with a unique formulation, the sandwich panels are fire-safe. The panels are certified for fire resistance ratings such as EI15, EI20, EI30, EW30, and EW60.

What are the disadvantages of PIR insulation?

PIR Insulation Material is Not Suitable for Awkward Angles and Shapes

PIR insulation panels are not well-suited for installation in awkward angles and irregular shapes, which can complicate the installation process.

Risk of Damage:

PIR insulation boards are susceptible to damage from sunlight and ultraviolet (UV) radiation. This means they must be kept away from direct sunlight exposure and adequately covered during storage and installation. Consequently, this requirement can increase installation costs, particularly for applications such as exterior wall insulation.
