How Insulated Panels Speed Up The Construction


Insulated Panels are prefabricated building panels utilized in floors, walls, ceilings on buildings. Putting in insulated panels for building constructions are aimed to ensure the energy efficiency, easy and fast installation 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 inflexible polyurethane foam. Different supplies akin to plywood, pressure-handled plywood for under-grade basis walls, metal, aluminum, cement board equivalent to Hardie Backer, and even exotic materials like stainless steel, fiber-reinforced plastic, and magnesium oxide can 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 cost, materials waste and energy effectivity are considered SIPs are comparable to more typical building methods.


The Thought 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 had been used to build test properties 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 had been being mass produced within the 1960's.

The right way 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're 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 in the foam. The block spline is a thin and slim SIP assembly that is inserted into recesses in the foam along the panel edges. These connections lead to a continuous foam core throughout the panels. This helps to eliminate 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 along the sheathing have to be covered with a steady line of panel tape. Openings could happen 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 settle for another enclosed component have to be properly sealed.

Benefits and Drawbacks


1. SIP provides the tighter building envelope and the walls will have higher insulating properties.
2. Lower in working costs.
3. Buildings made with insulated panels could be simply dismantled and reused
4. Insulated panel properties (power and thermal insulation property) will remain the same if reused.
5. It's value efficient as it can be put in easily


1. Quite poor performance with respect to the noise control.
2. Might be damaged by moisture. Higher to use the panels with waterproof surfaces.
3. Panels needs to 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.Also, it requires minimal equipment and workforce and therefore price effective.
