SIPs are high performance thermal efficient composite panels which
consist of a sandwich of two layers of structural board with an
insulating layer of foam in between for walls, roofs and floors in
new residential and commercial buildings.
B. Design theory:
Structural Insulated Panels (SIPs) have become a widely used
alternative construction material for homes and other buildings.
While many types of Composite Panel building systems have been
developed, SIPs now usually refers to panels made from a thick
layer of foam (polystyrene or polyurethane) sandwiched between two
layers of Oriented Strand Board (OSB), plywood or fiber-cement. The
result is an engineered panel that provides structural framing,
insulation, and exterior sheathing in a solid, one-piece component.
The basic design concept for SIPs is elegant in its simplicity, and
offers several advantages for constructing walls and roofs. Bonding
the foam core to the stiff outer skins creates a web-and-flange
structural strength (along the same principal as an I-beam) across
the length and breadth of the panel. With the capacity to handle
axial, bending, racking, and shear loads, properly designed and
assembled SIPs not only replace conventional framing, but will
withstand high wind, and seismic forces.
C. Advantages to use SIPs:
- Architectural Benefits
- High quality construction method.
- Comfortably warm, clean, and quiet.
- Cost Benefits
- Equal or lower first costs.
- Lower long term operating costs.
- Incentives available from utility service provider for energy
- Lower maintenance costs for you.
- Construction Process Benefits
- Easy to construct, with short learning curve.
- 60% shorter construction time
- Quick turnaround time for greater satisfaction.
- Increased builders production capacity.
- Environmental Benefits
- 50% less framing lumber.
- 50% more energy efficient.
- Requires less room at building site (less site disturbance).
- Less construction waste.
SIPs are prefabricated systems used primarily for walls and roofs.
SIPs employ composite materials, reduce waste through modular
construction methods, achieve high insulation values, and may be
used instead of many conventional building methods.
E. Alternatives of facing/core materials:
Same characteristic of facing materials: engineered board, such as
fiber cement board, MgO Board and plywood.
Sandwich insulating core: PU or XPS.
