Modular homes that use SIPs wall and roof technology

Habitech's modern approach to construction using smarter manufactured components is based on the material and structural efficiencies of the Structural Insulated Panels (SIPs) technologies we use in our walls and roofs. 


In comparison to traditional stud framing, Habitech's innovative composite timber/Magnesium Oxide board wall panels have been independently certified to have over:

  • 800% of the bearing capacity - ability to carry loads
  • 580% of the bending strength - bracing against wind 
  • 200% of the bending stiffness - minimising movement

While SIPs are often made using oriented strand boards (OSBs) that sandwich a layer of rigid foam plastic insulation inside, at Habitech, we use the superior performance of plantation grown Australian plywood for the interior faces of our wall panels. The foam core is made of expanded polystyrene (EPS).  SIPs are custom-made in factories and require little time and manual labour to manufacture.

SIPs technology has been used in US and European housing markets for over 40 years. During this time SIPs have become a trusted product in creating extremely energy efficient buildings. SIPs are a key component of buildings that are:

  • highly energy efficient
  • strong
  • high-quality
  • cost effective

Buildings made using SIPs technology are frequently chosen for ‘zero-energy housing studies’. Their high R-values and low air leakage contribute to a greater level of thermal performance than traditional framed construction.


Locking our sustainable house designs together

Our sustainable building components do much more than simply deliver base building materials. They provide an integrated system to lock together and seal the outside fabric/shell of our buildings.

The benefits of this panel locking system for our modular homes include:

  • versatility – the panels can be customised to many combinations
  • integrated cladding – our panels deliver a fully jointed cladding system
  • range of finishes – our panels can be finished with a variety of paint or rendered finishes

Sustainable houses with high-end aesthetic appeal


Our sustainable building system efficiently creates houses that have more generous proportions compared to traditional building practices:

  • 2.7m high ceilings as standard - 300mm higher than a common 2.4m standard ceiling.
  • 2.4m window head heights as standard - 300mm higher than the common 2.1m standard, letting in more light.   
  • 170mm thick walls instead of 90mm frames - our walls have a solid feel.
  • Full height internal doors - our doors go from floor to ceiling, allowing for effective ventilation.
