How Construction Tapes Enhance Metal Panel Insulation for Energy-Efficient Prefabricated Buildings
The construction of modern commercial and industrial buildings increasingly relies on prefabricated technologies that utilize metal plates or insulated sandwich panels. These methods are gaining popularity due to their ability to lower costs, reduce construction time, and minimize on-site assembly while maintaining high performance, durability, and energy efficiency.
To explore how advanced foam and tape materials for insulated sandwich and construction panels optimize manufacturing processes, create airtight building envelopes, and enhance energy efficiency, we turn to insights from Eef van Riet, Business Development Manager for Sustainable Construction at Saint-Gobain® Tape Solutions.
The Role of Metal Panel Insulation in Prefabricated Construction
Metal and sandwich panels provide cost-effective, versatile, and high-performance alternatives to traditional construction methods. The demand for lightweight, prefabricated building solutions is rapidly increasing due to the numerous benefits they offer.
Eef, what advantages do sandwich panels bring to prefabricated construction?
Sandwich panels deliver several key benefits for prefabricated construction, including fast assembly and ease of handling. Their optimized manufacturing processes ensure consistent quality and efficiency, leading to significant time and cost savings on-site.
When properly installed and sealed, these durable panels offer excellent thermal insulation, high resistance to weather and environmental factors, and acoustic performance. Depending on the panel grade and applied seals, they can also provide non-combustible properties for extended periods. Moreover, the panels can be repaired or replaced with relative ease if needed.
The Appeal of Metal Panels for Cost-efficient and Rapid Construction
New design possibilities and shapes, combined with excellent air- and watertight sealing properties and strong fire resistance, make metal panels an attractive option for cost-effective and fast construction projects.
What types of panels are currently being used?
There is a wide range of metal panels used in construction, varying based on their intended application (wall, roof, or other), insulation type (insulated or non-insulated), insulation thickness, panel shape, surface coating, and joint design. Each type offers different advantages and trade-offs, providing a variety of construction solutions to meet specific project requirements.
The Importance of Selecting the Right Materials for Energy-efficient Panel Construction
Insulated panels are essential for energy-efficient panel construction. By incorporating a core between the surface materials, the stiffness of the entire system can be significantly enhanced, while requiring much less material than solid structures.
These cores also enable the structure to effectively manage compression, shear, and bending forces, offering high thermal insulation performance that is increasingly crucial for energy-efficient buildings.
How can foam and tape materials optimize metal panel insulation for energy-efficient prefabricated construction?
While the panels themselves provide excellent insulation, the joints between panels or structures can be vulnerable points and thermal bridges. Innovative foam and tape solutions can address these weaknesses. Given the variety of materials and joint configurations, there is no “one-size-fits-all” solution; however, foams and tapes offer several key advantages: sealing, dampening, and isolation.
To determine the optimal solution, it’s essential to identify the specific application and manufacturing needs. The primary differentiator is whether the panels are produced through continuous or discontinuous processes. In continuous processes, all materials are processed simultaneously, and fully formed panels are cut to the desired length without halting production. This requires tape solutions that facilitate continuous length applications, such as Dynafoam®, PVC, or extrusions from our Norseal® product range, which are available in long spools for inline application of foam tapes on panel joints. These solutions enhance manufacturing efficiency and production speed while delivering excellent sealing performance even under challenging conditions.
Conversely, Norseal BCF (Butyl Coated Foam) or FS1000 intumescent and resilient sealing foam are ideal for air- and watertight sealing in discontinuous sandwich panel manufacturing due to their good conformability and material properties. What makes FS1000 particularly noteworthy is that, in addition to its sealing capabilities, it helps prevent fire and smoke propagation by forming a fire-blocking char when exposed to flames.
Each of the aforementioned solutions for continuous or discontinuous production has its strengths and weaknesses and can be tailored to meet specific requirements.
Regardless of the construction method or panel design, the right foam and tape materials can significantly enhance the tightness and energy efficiency of the building envelope, as well as the resistance and durability of the entire system, contributing to the overall value and quality of the building while reducing manufacturing and maintenance costs.
