PU + Rockwool Sandwich Panel Joint & Connection Details
The Fire Rated Rock Wool Sandwich Panel with PU Side Sealing can be integrated with different joint and trim solutions to meet the connection requirements of industrial and commercial wall systems. Properly designed joints help create a continuous building envelope while improving installation efficiency, appearance, airtightness, and long-term wall performance.
The PU side-sealed panel edges provide a stable connection area between adjacent panels, while compatible metal profiles and flashing components can be used for wall joints, base connections, and window openings.
Juntas decorativas
Decorative joint profiles create clean and consistent separation lines between adjacent sandwich panels. They help improve façade appearance while covering and protecting panel connection areas, making them suitable for industrial buildings where both functionality and architectural aesthetics are required.
Juntas centrales
Center joint systems provide secure connections between adjacent rock wool sandwich wall panels. Combined with PU side sealing and appropriate fasteners, the joint helps maintain panel alignment and insulation continuity while reducing potential thermal bridging at the connection.
Juntas entrelazadas
The interlocking joint design allows adjacent panels to fit closely together, creating a continuous wall surface. This connection simplifies installation and helps improve joint stability, airtightness, and weather protection for exterior wall applications.
Knee Wall Connections
Knee wall details provide a practical transition between the sandwich panel wall system and the lower wall or foundation structure. Proper flashing and sealing help protect the bottom edge of the panel against moisture penetration and improve the durability of the complete wall envelope.
Window Lintels & Window Sills
Special flashing profiles can be installed around window openings, including window lintels and window sills, to create clean transitions between the sandwich panel system and window frames. These details help direct rainwater away from the opening, protect exposed panel edges, and improve the overall weather resistance of the façade.
Complete Wall System, Not Just a Panel
A high-performance sandwich panel wall depends not only on the panel itself, but also on joint design, fasteners, flashing, sealing, and installation details. Glostar can provide suitable connection solutions according to project drawings, wall layout, window openings, and building requirements.
Send us your architectural drawings or wall elevations for recommended panel specifications and connection details.
Why Choose Rock Wool Sandwich Panels with PU Side Sealing?
Traditional rock wool sandwich panels provide excellent fire resistance, but the panel joints can become weak points in the building envelope if they are not properly designed or installed.
The PU side-sealing structure is designed to improve the performance of these critical joint areas.
Excellent Fire Performance
Rock wool is a widely used insulation material for buildings requiring enhanced fire protection. Its mineral-fiber structure provides excellent resistance to high temperatures and makes rock wool sandwich panels particularly suitable for industrial facilities and buildings with strict fire-safety requirements.
The actual fire resistance rating of the completed wall system depends on panel thickness, joint design, installation method and applicable testing standards. Fire-performance documentation can be provided according to project requirements.
Reduced Thermal Bridging at Panel Joints
Panel joints are an important part of the thermal envelope.
The PU side sealing provides additional insulation around the edges of the rock wool core, helping reduce heat transfer through panel connections and improving the continuity of the insulation layer.
This makes the panel suitable for projects where both fire resistance and energy efficiency are important.
Improved Joint Sealing
The tongue-and-groove connection creates a tighter interface between adjacent panels.
Combined with PU-sealed edges and the appropriate sealing system, the joint design can help improve airtightness and reduce the possibility of air and moisture penetration through the wall envelope.
Instalación rápida
The sandwich panel integrates the exterior metal facing, insulation core and interior facing into one prefabricated building component.
Compared with traditional multi-layer wall construction, prefabricated insulated wall panels can reduce on-site construction procedures and help contractors shorten installation time and labor requirements.
Excellent Acoustic Performance
The fibrous structure of rock wool provides useful sound absorption and acoustic insulation properties.
Rock wool insulated wall panels are therefore well suited to factories, workshops, equipment rooms and other buildings where industrial noise needs to be controlled.
Durable Metal Exterior Surface
The steel facings can be supplied with different metallic coatings and paint systems according to the project environment.
Options such as PE, SMP, HDP and PVDF coatings are available for different requirements regarding weather resistance, corrosion resistance, appearance and service conditions.
