Structural Insulated Panels (Sip panels) have become very popular for its use as an alternative construction material for residential and other building purposes. Sip panel essentially comprise of panels made from a thick layer of polystyrene or polyurethane foam, compressed between two layers of Oriented Strand Board or simple plywood or fiber-cement, as the need may be. Sips panels are an alternative to the foam core, mostly available as agriculture fibers rendering thermal and structural performance. The end-result is an engineered panel providing exterior sheathing, structural framing, and insulation sandwiched between a solid, one-piece component.

The core design of  SIPs is simple, rendering advantages for the construction of roofs and walls. Sip-panels create a web-and-flange structural strength by bonding the foam base to the outer skin, in tandem with the same principal pertaining to an I-beam. Having capacity to handle bending, racking, axial, and shear loads, SIPs are made to withstand high wind, forces than merely to be used as an alternative for conventional framing.

Advantages of Sip panels

The sip panel allow builders to speedily construct an strong, airtight, and energy efficient envelope for exterior of the building. Sip_panels can be quickly assembled even by workers who have no formal training. Sip panel render the benefit of Insulation capacity. Rendering of better overall air tightness to the building architecture is not the only USP of Sips panel. It also provides practical thermal performance than conventionally framed walls. Almost completely air-proof with no opportunity for internal convection is how one can describe a SIP Panel in depicting its functionality for building exteriors.

Variations in structural insulated panels

Made in standard thicknesses of 4 ½ ” to 6 ½”. Sips panels are 4 to 24 feet wide and 8 or 9 ft. high. Allow the panel to accept 2×4 top and bottom plates, the foam core of the SIP Panel is generally held back from its edge. However, Panel lengths of SIP can vary to accommodate higher roofs or ceilings spanning up to 30 ft. or above. Although wider Sip paneles are designed for door and windows, a standard panel width of 4 ft. is maintained by manufacturers for effecting ease in transportation. Also, by placing header sections between full-length walls of Sip-panel, rough openings for doors and windows could be made. An separate PATH Technology Inventory, Insulated Headers, can be designed by using sandwiched foam along with the primary use of Sip-panels. By injecting polyurethane core, many manufacturers render an unique dimension to Structural insulated panels. These types of Sips panels are for specialty or high-end usage. As such, are Sip panel used for eccentric cam locks, which ensure proper alignment in fittings, done. Sip used for doing up interior of a house or used for residential design work, are specialty panels which are modified by its manufacturer as per its use. Such type of panels render customized attributes, suitable to fit the house interior it is ordered for. However, specialty Sippanels would have to be ordered much in advance so as to provide accurate and appropriate usage in designing of the house interior.
