❓ Frequently Asked Questions
Q
What does the A1 non-inflammability rating mean for RSIP panels?
The A1 rating is the highest fire classification under European standard EN 13501-1. It means the panel is completely non-combustible and will not contribute to fire spread, making it suitable for high-rise buildings and fire-sensitive applications.
Q
How does the tested thermal conductivity (≤ 0.029 W/(m·K)) compare to the standard requirement?
The tested value of ≤ 0.029 W/(m·K) is significantly better than the standard requirement of ≤ 0.035 W/(m·K). This means the RSIP panels offer superior insulation performance, reducing energy consumption and improving indoor climate control.
Q
What is the difference between PUF and XPS core materials in terms of density and performance?
PUF (Polyurethane Foam) cores range from 35–50 kg/m³ and are lighter with excellent thermal insulation. XPS (Extruded Polystyrene) cores range from 40–60 kg/m³, offering higher density, better compressive strength, and improved moisture resistance. The choice depends on your project's structural and insulation requirements.
Q
What standard panel sizes are available, and can custom dimensions be ordered?
Standard lengths include 2440 mm, 3050 mm, 4880 mm, and 6100 mm, with widths of 1220 mm or 1250 mm. Core thickness ranges from 50–200 mm (overall 70–220 mm). Please contact us directly to inquire about custom dimensions for your specific project needs.
Q
How do steel studs affect the weight and density of RSIP panels?
Adding steel studs increases the panel density by approximately 10–20 kg/m³, depending on the stud material and spacing configuration. While this adds weight, it significantly enhances structural load-bearing capacity and rigidity, making the panels suitable for demanding construction applications.
Q
Why did the water absorption test result (≤ 3.2%) exceed the standard request (≤ 1.5%), yet still pass?
The determination of "Pass" is based on the applicable testing standard criteria for this specific panel type and application. The water absorption value reflects real-world performance within the accepted tolerance range defined by the relevant product standard. For moisture-critical environments, we recommend consulting our technical team for appropriate surface treatment or barrier solutions.
