❓ Frequently Asked Questions
💬
What is a Reinforced Structural Insulated Panel (RSIP)?
A Reinforced Structural Insulated Panel (RSIP) is a high-performance building panel that combines thermal insulation core materials (such as PUF or XPS) with structural reinforcement, typically using steel studs or similar elements, to deliver both insulation and load-bearing capabilities in a single panel system.
💬
What fire rating does the RSIP achieve?
The RSIP achieves an A1 non-inflammability rating — the highest fire resistance classification — meeting and exceeding the standard request. This makes it suitable for applications where strict fire safety regulations apply.
💬
What is the difference between PUF and XPS core options?
PUF (Polyurethane Foam) cores have a density of 35–50 kg/m³, offering lightweight construction with excellent thermal insulation performance. XPS (Extruded Polystyrene) cores have a higher density of 40–60 kg/m³, providing better compressive strength and moisture resistance. When steel studs are added, density increases by an additional 10–20 kg/m³ depending on stud material and spacing.
💬
What panel sizes are available for the RSIP?
RSIPs are available in a range of standard sizes. Core thickness ranges from 50 to 200 mm, with an overall thickness of 70–220 mm. Available lengths include 2440, 3050, 4880, and 6100 mm, while widths are available at 1220 mm and 1250 mm to suit various construction requirements.
💬
How does the RSIP perform in terms of thermal conductivity?
The RSIP delivers a tested thermal conductivity of ≤ 0.029 W/(m·K), which is significantly better than the standard requirement of ≤ 0.035 W/(m·K). This superior insulation performance helps reduce energy consumption and maintain comfortable interior temperatures year-round.
💬
What tensile strength does the RSIP provide?
The RSIP achieves a tensile strength of ≥ 9.0 MPa in testing, far exceeding the minimum standard requirement of ≥ 5.0 MPa. This enhanced structural strength makes the panel suitable for demanding building applications where both insulation and structural integrity are critical.
