Frequently Asked Questions

Rock wool sandwich panels for exterior building insulation are prefabricated building envelope panels made with a non-combustible rock wool core and metal facings. They are used for exterior walls and roofs where projects need fire safety, stable thermal insulation, acoustic performance, and efficient installation in one system.
Compared with multi-layer exterior wall systems built on site, rock wool sandwich panels simplify the envelope into one integrated solution. They help reduce on-site complexity, improve consistency, and combine fire performance, insulation, and sound control in a single exterior wall system.
These exterior insulation panels provide stable thermal performance for long-term building envelope use. Based on the current material set, the rock wool core has a thermal conductivity of about λ≈0.040 W/m·K, helping reduce heat loss and support more controlled heating and cooling costs over the building lifecycle.
Yes. Rock wool sandwich panels are not only about fire safety and insulation. They also support acoustic comfort by helping reduce outside noise. In the current materials, exterior wall sound insulation can reach Rw 30dB+, which makes the system suitable for projects in industrial zones, busy roadsides, schools, offices, and other noise-sensitive environments.
SQPANEL rock wool sandwich panels use interlocking or concealed-fix joint designs, combined with sealing and waterproof detailing. This helps improve airtightness, water resistance, and overall facade integrity, while also supporting a cleaner exterior appearance when properly designed and installed.
