JUST SIPS Structural Insulated Panels

JUST SIPS have engineered an environmentally sustainable, structural insulated panel utilizing a combination of new generation technology and light weight materials to achieve an incomparable building system with the benefits of strength, cost effectiveness, quality and construction efficiency.

"The Just Sips walling system is considered to be an alternative solution and as such, is required to meet the relevant performance provisions of the BCA. Having assessed all the documentation provided in support of the Just Sips system, we are of the opinion that the system meets the relevant performance requirements of the Building Code of Australia volume 2(2010). The Just Sips walling system is approved as a Panel Building System for cyclonic conditions, including Region D (Cat2)* additional engineering detail may be required to accommodate particular design criteria."

Key Benefits:

Just Sips panel are lightweight, weatherproof, highly impact resistant and designed to withstand earthquakes and cyclonic conditions. The modular system can be erected quickly and easily with minimal semi-skilled labour. Large scale projects can be manufactured to specification in our state-of-the-art facilities and flat packed for transport faster and more economically than conventional building materials.

Versatile. The Just Sips system allows design freedom ensuring that superior housing can be provided in virtually any configuration

On-site costs are considerably lower. There is minimal construction waste. Eliminates wet trades, Electrical and Plumbing can be completed very quickly. No need for expensive crane hire as the panels can be easily lifted into position. Reduced or nil costs for scaffolding. Noise pollution reduced significantly. Savings on shipping/ transportation costs.

Durable & easy to maintain. The outer skins are extremely durable. During manufacture the panels are laminated to the cellular thermoset core under pressure for superior bond strength. The finished product is highly robust and resilient to harsh weather conditions.

Green & energy efficient. Just Sips panels have excellent thermal properties resulting in lower energy costs. This relates to lower carbon/greenhouse gas emissions.


Just Sips are suitable for:

  • Residential Housing Project Developments
  • Remote Indigenous Housing
  • Relocatable Housing
  • Mine Site Accommodation

Panel sizes:

Just Sips are pre-manufactured in the following three standards sizes:

  • 1.2 m x 2.4 m
  • 1.2 m x 2.7 m
  • 1.2 m x 3.0 m
Custom lengths and specific job requirements such as window lintels are manufactured to specification

External wall & roof finishes:

External finishes that are easily applied (but not limited to) include: - Cement rendering & textured coatings - Corrugated sheet metal ,Colorbond - Brick, tiles, stone & limestone cladding - PVC & aluminium cladding - Timber & plywood Just Sips accommodate all traditional roofing styles and materials

Thermal specifications:

Just Sips fully comply with the Building Codes of Australia requirements for minimum R Values

Fire resistance:

Just Sips has been tested to Australian Standard AS1530.3. The following indices were obtained:

Early Fire Hazard Indices  (Lower values are better) 
Ignitability Index 
Spread of Flame Index 
Heat Evolved Index 
Smoke Developed Index 

Life expectancy:

Just Sips design criteria meets a 50 year return period. In plain terms the structural integrity of a Just Sips panel remains unchanged in 50 years.

Resistance to termites:

The cellular foam core of the Just SIPS panel can be fabricated with Perform Guard® termite resistant expanded polystyrene as required. In addition we recommend the installation of an approved termite management system conforming to BCA requirements.
