All testing to date has have found wall temperatures all within the New Zealand Building code. The IntensiFire has been used without issue in homes since 2011.
The critical aspect to safety is the wall temperatures behind your fire.
There is no precedent for a retrofit product like the IntensiFire, so I am having to develop the systems to ensure safety of the technology. You can help me do this. You can test yourself using a cheap thermometer, my distributors and I will help you through this process. A simpler method is in development so that checking your temperatures will be easier. We believe it is safe based on our experience, but strongly recommend you check because we don’t want you to set your wall on fire. Take a record of the measurements. From these measurements a statement can be produced for your local authority, and insurance company, as a measure of proof that your fire is safe.
In New Zealand you can test compliance with C2.2 of the building code by measuring wall temperatures, a maximum of 90°C. It is also the opinion of the Ministry for Building and Innovation that a building consent is required when fitting an IntensiFire.
There are also simple and cheap methods for wall protection if needed.
