Introduction

Insulated Panels are prefabricated building panels used in floors, walls, ceilings on buildings. Putting in insulated panels for building constructions are aimed to make sure the energy efficiency, easy and fast installation and a lower in operating costs. A structural insulated panel (SIP) is a composite building material; consisting of an insulating layer core sandwiched between layers of metals.

Options of SIP

SIP’s are commonly made of the Oriental Strand Board (OSB) panels sandwiched round a foam core made of expanded polystyrene (EPS), extruded polystyrene (XPS) or rigid polyurethane foam. Other supplies akin to plywood, pressure-handled plywood for beneath-grade foundation partitions, steel, aluminum, cement board such as Hardie Backer, and even unique materials like stainless metal, fiber-reinforced plastic, and magnesium oxide will also be used in replacement of OSB. SIPs provide continuous air and vapor barrier as well as elevated R-Value compared to traditional constructions. When labor value, material waste and energy effectivity are considered SIPs are comparable to more conventional building methods.

History

The Concept of Structural Insulated Panels (SIPs) introduced The Forest Products Laboratory in Madison, Wisconsin in 1935. The laboratory developed a prototype panel consisted of framing members, plywood and hard board sheathing, and insulation. These initial panels have been used to build test homes and tested after 30 years to disclose that the panels retain their initial strength. In 1952 Alden B. Dow created the primary foam cores SIPs which were being mass produced within the 1960’s.

Methods to use SIP

The SIPs are designed to resist axial loads, shear loads and out of edge loads. These can be utilized for floors, walls, roofs etc… for the buildings. They have the ability to resist the bi-axial bending and lateral shear; so, they’re very much suitable for use as roofs and floors. Probably the most widely used panel joint connections are the Surface spline and Block Spline. The Surface spline Joint Connection consists of the strip of OSB or plywood inserted into slots within the foam. The block spline is a thin and narrow SIP assembly that’s inserted into recesses in the foam along the panel edges. These connections result in a steady foam core across the panels. This helps to remove air filtration at the joints.

Another joint connection is Mechanical cam locks; create a tighter joint between the panels. In any type of connection, the seam alongside the sheathing have to be covered with a steady line of panel tape. Openings might occur at the edges and corners of the panel, and so the panel foam could be recessed to access lumber headers. Any opening within the SIPs that accept another enclosed element must be properly sealed.

Benefits and Drawbacks

Benefits:

1. SIP provides the tighter building envelope and the walls will have higher insulating properties.

2. Decrease in operating costs.

3. Buildings made with insulated panels could be simply dismantled and reused

4. Insulated panel properties (energy and thermal insulation property) will remain the same if reused.

5. It’s cost efficient as it may be installed simply

Drawbacks:

1. Quite poor performance with respect to the noise control.

2. May be damaged by moisture. Better to use the panels with waterproof surfaces.

3. Panels must be properly protected from pests/insecticides.

4. Requires a proper mechanical ventilation system

5. Modification of the initial project is costly.

Conclusion

The Structural Insulated Panels come prefabricated and ready to be assembled, and hence it helps to speed up the construction.Also, it requires minimal equipment and workforce and hence cost effective.
