Mil-Max Super-Insulated Construction System:

The extremes of Australia’s differing climatic zones has to date made any single building material a poor standard solution for most home construction requirements.

The thermal performance of the common brick veneer home is very poor, allowing warmth to escape in winter and radiating heat to invade the living spaces during summer.

In response to this problem T3Energy has developed it's super-insulated light weight wall construction system, Mil-Max.

The Mil-Max Building system consists of a central core of  rigid Polyisocyanurate foam with an outside skin of Magnesium Oxide Board.

This combination allows for a building system that requires Minimum Installation Labour with Maximum insulation value. Hence the name Mil-Max.

The result is stylish, affordable and energy efficient building system that will impact your energy bills for years to come.

Laying the Mil-Max blocks is fast and easy.

How other materials stack up:

R-value indicates how well a wall insulates. For example a wall with an R-value of 2 stops twice as much heat from entering or exiting a building as a wall with an R-value of 1. T3Energies’s Mil-Max blocks reach factors of R-8

The comparison below illustrates how this compares with existing masonry and metal technology:

Revolutionary Benefits:
Higher thermal performance can be achieved by adding additional layers of insulation to conventional construction techniques.  Taking this path means adding materials and labour to the process.   Mil-Max avoids this by reinventing the wall construction process.
By simply laying the wall blocks, No mortar, no filling of voids, Mil-Max displaces at least 4 separate conventional processes:
  • Structural frame  (foam core is load bearing)

  • Building foil vapor barrier (foam is closed cell resisting vapor transfer)

  • External skin.  bricks, weather board etc. (Blocks come with internal and external skins already bonded ready for paint/texture finish)

  • Insulation  (Foam core has insulation rating of R8+)

The whole system is also fire resistant with the Magnesium Oxide skins being non-combustable and the foam core self extinguishing.
