SIP (Structural Insulated Magic Boards)

SIP (Structural Insulated Magic Boards)

Structural insulated panels (SIPs) are high performance building panels used in floors, walls, and roofs for residential and light commercial buildings. The panels are typically made by sandwiching a core of polyurethane foam insulation between two structural skins of Fiber Cement boards. With proven history of performance since 1952, SIPs are technologically advanced and superior alternative to traditional building systems.

SIP is virtually impervious to fire, water, and insects, does not feed on molds or mildew, is non-toxic, non-flammable, non combustible, durable, maintains dimensional stability even when wet and enjoys exceptional bonding characteristics.

The components of the Structural Insulated Panel form a monolithic unit. The insulating core and the two skins of an SIP panel are non-structural and insubstantial components by themselves, but joining rigid polyurethane foam insulation to external magic board sheathing results in a building product that is predictable, resource efficient and cost effective.

Whether pressure-laminated or factory produced under strictly controlled conditions, these materials act synergistically to form a composite that is much stronger than the sum of its parts.

Techno Homes Structural Insulated Panels (Magic Boards)

Techno Homes has developed its own SIP system using the well known and tested SIP technology created in North America, but replacing the wooden OSB facings and polystyrene core, with magic board facings and Polyurethane foam core; thus ensuring complete adaptation to local requirements, taste, culture, and climatic conditions.

SIPs are used for residential and commercial buildings providing developers and homeowners with energy efficient, structurally superior, environmentally friendly and easy to install building panels, replacing traditional stone-concrete construction.

SIPs are easy to install and versatile for exterior walls, foundations, roofs, additions, and floors, for all types of buildings, residential, commercial, industrial, and any type of shell where efficiency and durability is a requirement.

How does it work?

An SIP is a layered structural system composed of a low-density core material bonded to, and acting integrally with, relatively thin but high-strength facing materials. When used as a wall, roof, or floor system in housing, the sandwich panel provides exceptional strength both vertically and horizontally.

In a load-bearing wall, the two facings act as slender columns continuously supported by the core material to resist compression and buckling. In bending due to a live load or a wind load applied to a panel, the facings take most of the tensile and compressive forces and the core provides resistance to shear. The core and facings acting integrally provide exceptional stiffness to the member.

Structurally an SIP can be compared to an (I beam) or an (I-column), where the foam core acts as the web while the facings or outer skins are analogous to the flanges. All the elements of an SIP are stressed; the skins are in tension and compression, while the core resists shear and buckling. Under load the facings of an SIP act as slender columns, and the core stabilizes the facings and resists forces trying to deflect the columns. Accordingly the thicker the core, the better is the buckling resistance. So large core SIPs offer more insulation and a stronger structure.

Magic panel SIPs are considered as a complete building system, delivering building efficiencies by replacing several components of traditional construction including Studs, Insulation, Vapor barrier and Air barrier. All in one panel called the Magic Panel.

Properties and Applications

The use of Magnesium Oxy-Chloride Mineral Cement is not a new discovery. It dates back almost to the Pyramids in Egypt and the Great Walls in China. Magnesium Oxy-Chloride Cement based mortar and stabilizers; have been used extensively on The Great Wall of China and have outperformed, and even outlived natural stone.

Like any other sheathing board, Magic board can absorb water but its performance is unaffected. Thus it can be used indoors, outdoors, in damp locations, and even in wet places such as shower walls.

Magic board can be used structurally, as in bracing for internal walls and internal partitioning, and also semi-structurally, such as an underlayment for flooring.

SIPs produce a structurally superior, better insulated, faster to erect and more environmentally friendly structure than ever before possible.

The superior strength o Magic SIPs allows for more flexible building design:

  • Continuous reinforcement by the high-density foam-core gives Magic SIPs superior axial load-bearing properties.
  • Shear loads are more evenly distributed throughout surfaces, particularly with increased fastener frequency.
  • Load capacity anywhere from 300% to 700% stronger.

Since their introduction more than 60 years ago SIPs have been used in thousands of buildings and have been exhaustively tested, passing every barrier with flying colors. SIPs are now a government and industry accepted material for residential and light commercial applications in North America, Europe, Japan and New Zealand, and all other countries where quality, efficiency and safety count.
