118mm Structural Insulated Panel (SIP) - Sandwich Panel (9mm OSB + 100mm EPS + 9mm OSB) - 1200mm x 2400mm

118mm Structural Insulated Panel (SIP) comprises a 100mm thick core of rigid Expanded Polystyrene (EPS) insulation sandwiched between two 9mm thick Oriented Strand Board (OSB) sheets. It is an advanced building component designed for high-performance and energy-efficient construction. Sandwiched between two 9mm Orientated Strand Board (OSB) sheets, the panel ensures superior strength and durability. The OSB sheets are engineered to distribute loads evenly, enhancing the panel's stability under various conditions. The structural integrity of SIPs is greatly increased due to the combination of materials. The 100mm EPS core acts as a continuous insulation barrier, while the 9mm OSB sheets on either side provide a rigid, sturdy surface. This innovative construction ensures that the components work together cohesively, delivering a panel that is both lightweight and exceptionally strong.

The synergy between the EPS core and the OSB facings contributes to the high load-bearing capacity of SIPs. This integrated structure allows for the even distribution of stresses and minimises the potential for warping or bending, significantly enhancing the longevity and performance of the panels. This SIP is ideal for walls, roofs, and floors where high insulation values and structural integrity are paramount.

The OSB sheets are bonded to the EPS core under high pressure, creating a strong, rigid, and monolithic unit. This sandwich construction offers significant structural advantages. The rigid EPS core acts as a strong, lightweight load-bearing element, distributing forces evenly across the entire panel. The OSB sheets, bonded to the core, provide a continuous surface, significantly increasing the panel's shear strength and resistance to racking (lateral movement). In traditional timber frame construction, stress concentrations can occur at the joints where individual members connect. The monolithic nature of the SIP minimises these stress points, leading to a more robust and less prone to failure.

The integrated design of the SIP creates a highly rigid diaphragm, which effectively resists wind loads, improving the overall structural stability of the building. The high shear strength and stiffness of the SIP make it more resistant to the lateral forces generated by earthquakes. The SIP's strength lies in its integrated design, the resulting panel exhibits significantly higher strength-to-weight ratio and superior structural performance compared to traditional timber framing or individual components used in isolation.

SIPs are manufactured off-site in a controlled factory environment. This minimises the number of individual components to be installed. This reduces the need for extensive on-site framing and sheathing. The faster construction process translates to reduced labour costs and a quicker project completion timeline.
