Insulated Panels are prefabricated building panels used in floors, walls, ceilings on buildings. Putting in insulated panels for building constructions are aimed to ensure the energy efficiency, simple and fast set up and a decrease in operating costs. A structural insulated panel (SIP) is a composite building material; consisting of an insulating layer core sandwiched between two layers of metals.
Features of SIP
SIP’s are commonly made of the Oriental Strand Board (OSB) panels sandwiched around a foam core made of expanded polystyrene (EPS), extruded polystyrene (XPS) or rigid polyurethane foam. Different supplies comparable to plywood, pressure-treated plywood for beneath-grade foundation partitions, metal, aluminum, cement board such as Hardie Backer, and even unique supplies like stainless steel, fiber-reinforced plastic, and magnesium oxide will also be used in replacement of OSB. SIPs provide continuous air and vapor barrier as well as increased R-Value compared to traditional constructions. When labor price, material waste and energy efficiency are considered SIPs are comparable to more typical building methods.
The Idea of Structural Insulated Panels (SIPs) launched 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 were used to build test houses and tested after 30 years to disclose that the panels retain their initial strength. In 1952 Alden B. Dow created the first foam cores SIPs which have been being mass produced in the 1960’s.
How 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 withstand the bi-axial bending and lateral shear; so, they are very a lot suitable to be used as roofs and floors. 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 slim SIP assembly that is inserted into recesses in the foam alongside the panel edges. These connections result in a steady foam core throughout the panels. This helps to eliminate air filtration on the joints.
One other joint connection is Mechanical cam locks; create a tighter joint between the panels. In any type of connection, the seam along the sheathing must be covered with a continuous line of panel tape. Openings might happen on the edges and corners of the panel, and so the panel foam can be recessed to access lumber headers. Any opening within the SIPs that accept one other enclosed element should be properly sealed.
Benefits and Drawbacks
1. SIP provides the tighter building envelope and the walls will have higher insulating properties.
2. Lower in operating costs.
3. Buildings made with insulated panels could be simply dismantled and reused
4. Insulated panel properties (strength and thermal insulation property) will remain the same if reused.
5. It’s value effective as it might be put in easily
1. Quite poor performance with respect to the noise control.
2. Might be damaged by moisture. Better to make use of the panels with waterproof surfaces.
3. Panels must be properly protected from pests/insecticides.
4. Requires a proper mechanical air flow system
5. Modification of the initial project is costly.
The Structural Insulated Panels come prefabricated and ready to be assembled, and therefore it helps to speed up the construction.Additionally, it requires minimal equipment and workforce and therefore cost effective.
