❓ Frequently Asked Questions
Q
What fire rating does the Reinforced Structural Insulated Panel (RSIP) achieve?
The RSIP achieves an A1 non-inflammability rating, which is the highest fire classification available. This means the panel is non-combustible and meets the most stringent fire safety standards required for building construction.
Q
What is the thermal conductivity performance of the RSIP?
The standard requirement for thermal conductivity is ≤ 0.035 W/(m·K). The tested result of the RSIP panel achieves ≤ 0.029 W/(m·K), exceeding the standard and delivering superior insulation performance for energy-efficient buildings.
Q
What core insulation materials are available for the RSIP?
The RSIP is available with two core insulation options: PUF (Polyurethane Foam) with a density of 35–50 kg/m³, offering lightweight construction and excellent insulation; and XPS (Extruded Polystyrene) with a density of 40–60 kg/m³, providing higher density and better compression resistance. Panels with steel studs add an additional 10–20 kg/m³ depending on stud material and spacing.
Q
What standard panel sizes are available for the RSIP?
RSIP panels are available in a range of standard sizes. Lengths include 2440 mm, 3050 mm, 4880 mm, and 6100 mm. Widths are available at 1220 mm and 1250 mm. Core thickness ranges from 50 to 200 mm, with an overall panel thickness of 70 to 220 mm, accommodating diverse construction requirements.
Q
How does the tensile strength of the RSIP compare to the standard requirement?
The standard minimum tensile strength requirement is ≥ 5.0 MPa. The RSIP testing result demonstrates a tensile strength of ≥ 9.0 MPa — nearly double the required minimum — confirming the panel's structural integrity and suitability for demanding load-bearing applications.
Q
What applications are Reinforced Structural Insulated Panels (RSIP) suitable for?
RSIPs are designed for applications that require both high thermal insulation and structural reinforcement. They are commonly used in walls, roofs, and floors of residential, commercial, and industrial buildings, as well as in modular construction, cold storage facilities, and prefabricated structures where energy efficiency and structural performance are critical.
