Ecohousing Building Systems About Us

Declining traditional building skills and more stringent energy requirements for new homes, coupled with increased interest in and acceptance of a fresh approach to rapid build housing using state of the art building materials. With heating and cooling accounting for more than 40% of Australia’s total energy consumption the Thermal qualities of the Ecohousing Building Systems provide big savings in energy requirements.

The Ecohousing Building Systems provides many advantages including:

  • Suitable for high wind/cyclone areas
  • Structural insulated wall/roof and floor panels
  • Wall panels sheeted with durable fibre cement sheeting
  • Roof/Floor panels sheeted with High Tensile Spandek Profile
  • Ease and speed of assembly
  • High strength and durability (50 years plus)
  • Ease and speed of building
  • Fire resistance in accordance with ASTM6092

Vermin and Pests Resistance

The resistance of fibrous cement faced, polyurethane foam cored construction panels to attack by
vermin has been studied internationally. Research has indicated the following:
1) Compressed Fibre Cement sheeting offers a high degree of resistance to penetration by vermin.
2) The polyurethane core materials provide no food value to vermin.
3) Inherent internal strength of the polyurethane core materials makes penetration of the core considerably more difficult than for other materials such as polystyrene foam or fibrous type insulations. The additional effort required to penetrate the polyurethane core acts as a vermin deterrent.
4) Design of the Ecohousing panels is such that access to the polyurethane foam core is only possible at the top and bottom edges of walls.
5) Vermin access into the core of Ecohousing roof panels is not anticipated to be of concern due to uncomfortably high internal temperatures experienced within the panel resulting from direct sunlight exposure.
6) To prevent entry of vermin, birds etc at the corrugated wall-roof junction or other exposed regions, a profile cut, bitumen impregnated flexible foam seal or profile cut perforated metal barrier is recommended.
The resistance of fibrous cement faced, polyurethane foam cored construction panels to attack by termites is not readily answered. There are no published studies by recognised bodies such as the CSIRO etc. The following points of fact however do apply:
1) The polyurethane core materials provide no food value for termites or other insects.
2) Not only does the polyurethane foam not provide termites with a food source, the very low humidity environment within the panel is also not attractive to them. As a result, if there is a more suitable environment, with a food source elsewhere, it is likely it will be the favoured option.
3) Termites are no more a problem in Structural Insulated Panel (SIP) construction than in conventional construction. Countries that have termite problems, such as Australia and most other countries adapting good building practices, it is already a construction requirement to use preventive treatments.
The resistance of fibrous cement faced, polyurethane foam cored construction panels to attack by vermin has also been studied internationally. Research has indicated the following:
1) Suitably sealed/painted compressed fibre cement sheeting will offer very limited opportunity to support surface growth of fungi or bacteria.
2) The polyurethane core materials provide no food value for micro-organisms.
3) The polyether-polyurethane chemical composition of the core material is well known and documented to be resistant to microbial attack, even when water immersed.
4) Unlike polystyrene, the closed cell structure of the polyurethane foam provides superior resistance to moisture and water vapour ingress than can be achieved by polystyrene foam.
This results in a very low humidity environment within the polyurethane core, further preventing fungal or microbial growth.
Laboratory testing by Chemind Hi-Tec Polymers, International studies and associated research yielded this information regarding the resistance of Ecohousing Building Systems construction panels to vermin and pests.

Drawing from over 30 years of experience in the insulation of domestic and commercial buildings, we have developed and patented a building system using structural insulating building panels. Ecohousing Buildings result in cost effective, energy efficient and ecologically sustainable structures.We believe that high quality products should be affordable whilst being ecological. By using an extremely efficient and innovative production system we are proud to provide the highest quality products at highly attractive prices. Ecohousing is committed to the development, manufacture and marketing of environmentally friendly products and methods.

We are building for the future, satisfying the need for an affordable, ecologically sound and totally insulated building solution that combines the strength of fiber-cement with the outstanding thermal qualities of structural polyurethane foam. The polyurethane is environmentally friendly and is classed as zero ODP, which means that it is a ZERO OZONE DEPLETING PRODUCT.

Our products are classified as Structural Insulated Panels (SIPs). Their lightness, innate strength and load-bearing capabilities make them ideal for minimal-frame building methods, with consequent significant savings in construction time and costs.

High thermal resistance ratings mean that Ecohousing homes easily exceed minimum energy efficiency requirements. The Ecohousing Building Systems are protected by world-wide patents.
