SIPs Features
Structural insulated panels (SIPs) are a high-performance building system for residential and light commercial construction.
​Thermal Performance
​ R-Values
SipsBuild’s Structural Insulated Panels provide superior thermal performance, which will last the life span of the building. This is due to the solid core of fire rated Expanded Polystyrene (EPS) throughout the structure which ensures that the building is heated and cooled evenly, remains free from cold and hot spots and will benefit from reduced heating and cooling costs. EPS delivers R-value ranging from 3.20 to 4.60 per inch.
​
Low U-Values
​SipsPacific’s Structural Insulated Panels offer extremely high thermal performance. As an example, the EPS core of rigid insulation and fibre cement sheeting can achieve U-Values as low as 0.14 Watts per Meter Squared Kelvin (W/m2K) or better, making significant savings on your annual heating costs.
​
SIPSBUILD SYSTEM
The panels consist of a fire rated insulating foam core sandwiched between two structural facings, typically Magnesium Oxide Board (MGO) or Fibre Cement Sheeting (FC). SIPs are manufactured under factory-controlled conditions and can be fabricated to fit nearly any building design. The result is a building system that is extremely strong, energy efficient and cost effective. Building with SIPs will save you time, money and labour.

• It is a high-performance building panel for floors, walls and roofs in residential and commercial Buildings.
• Panels are typically made using BASF's Graphite Polystyrene (GPS) slabs sandwiched between two structural skins.
• MGO & FC Boards are non-combustible materials. GPS is produced with an included fire retardant.
SipsBuild's panels are joined by a concealed structural steel framework which gives an extremely strong, energy efficient, lightweight structure.
​Light gauge steel structures are currently being replaced with Fibre Reinforced Polymer (FRP) Pultrusions to eliminate the use of steel products. This includes the introduction of FRP Window and door Frames.
Panels have been tested by Curtain University which confirm they can withstand up to 2.5 times the cyclone loading requirements.
The panels can be produced in three nominal thicknesses of 90mm, 100mm, and 150mm depending on requirements. Indicative R values are from R 2.3 to R 4,6.
The panel is made from two sheets of MGO Board (9mm) or Fibre Cement board (6mm) non-combustible to AS1530:1 class 1. The board is pressure bonded to a central core of Graphite Polystyrene to AS 1366.3 which contains a flame retardant. The perimeters of each panel are encased with light gauge structural and semi structural steel members
All panel joints are watertight and sealed by application of a continuous bead of Polyurethane Sealant. All joints are then taped and flushed the walls are then ready for painting or whatever finish is required. This makes entire walls single airtight structures.
​Continuous Insulation
Limited Cold Bridging
​​​SipsBuild’s is currently developing a continuous strip of Fibre Reinforced Polymer (FRP) for joining panels which has almost zero heat conductivity providing a continuous enclosed insulating core through the walls and roof of the building. This greatly improves the thermal efficiency of the building compared to timber frame studs and cavity insulation which is prone to slumping and mortar drops during the construction process.
​Air Tightness
Poor airtightness is a major cause of heat loss. A SipsBuild home provides a controllable indoor environment due to the superior air tightness of the system.
​
Controlled Manufacture & Construction
Fast Construction Method
By using SipsBuild’s Structural Insulated Panels, on-site construction time can typically be reduced by up to thirty percent. Onsite construction as well as Factory construction times will be greatly reduced with the introduction of the planned large format panel manufacturing facility in SE Queensland.
Factory produced modules further reduces onsite construction time as well as eliminates construction waste.
