What is a Double-Notched Cold Room Panel? | Karsey
In cold storage systems, panel thickness is not the sole factor behind significant energy loss. The primary, often overlooked issue lies in the thermal bridges formed at the joints where panels meet. No matter how high the quality of a panel is, incorrect joint designs can cause unwanted heat transfer between the internal and external environments. This not only spikes energy consumption but also leads to condensation and performance degradation over the long term. The double-notched wall panel developed by Karsey Industry features a specialized connection geometry designed specifically to mitigate this issue.
What is a Thermal Bridge? A thermal bridge is an area within an insulated structure where heat transfers at a substantially higher rate than through the surrounding insulation. In cold rooms, these vulnerable points are predominantly found at panel joints, corner details, door perimeters, and floor-to-wall connections. If these joints are not engineered correctly, severe energy losses will occur regardless of how thick the panels are.
How Does the Double-Notched Design Work? In the double-notched system developed by Karsey Industry, precise geometries at the panel edges ensure a highly controlled, seamless interlock. It optimizes the contact surface area, particularly at the intersection of floor and wall panels. As a result: ✔ The heat transfer path is extended. ✔ Air leakage is significantly reduced. ✔ The risk of thermal bridge formation is eliminated. ✔ A homogenous and continuous insulation layer is achieved across all joints.
Why Choose a Double-Notched Structure? Standard panel joints provide only a single flat transition surface, whereas the double-notched architecture breaks the linear paths where energy losses typically propagate. This precise geometry impedes the advancement of warm air, prevents air infiltration, and enhances the overall mechanical stability of the panel assembly. Manufactured via precise Polyurethane (PUR) injection without a sheet heating system, the panels preserve their cellular structure, maximizing interlocking efficiency. Consequently, the system delivers superior insulation performance driven not just by raw thickness, but by advanced connection design.
Ideal Applications and Projects The double-notched panel system is highly recommended for applications where energy efficiency is critical, such as:

The Karsey Industry Difference At Karsey Industry, we go beyond manufacturing standard panels; we completely re-engineer the joint details. We understand that the true performance of a cold storage facility depends heavily on how seamlessly the panels interlock, rather than just their standalone thickness. Driven by this engineering philosophy, our double-notched panel technology provides a robust solution for projects prioritizing energy efficiency and long-term durability.
