Spray on insulation ticks all the boxes
Transforming that old shed into a dry, temperature-constant, commercially viable building is possible with a new economical product that is becoming a game-changer in insulation.
NZ Foam is a cost-effective insulation solution for cool stores, growing or packing sheds, grain storage silos, day sheds for livestock, containers, out buildings or worker accommodation. It can pay for itself over time with its ability to reduce energy costs. The benefits are multiple, such as faster cooling and heating. There are no gaps so it keeps out dust, pollution and outside contaminants. Air cannot escape. This upgrades a workable environment from an established structure without the cost and time factor of rebuilding. NZ Foam will work with builders and architects for refurbishments, and also new builds, to gain the most from its passive heating and cooling advantages.
By association, NZ Foam is an awardwinner in the 2017 Canterbury Registered Master Builder House of the Year awards, for its contribution in sustainability and measurable excellence in providing warm, dry residential homes throughout the country.
NZ Foam has over 20 years’ experience but, in comparison, spray foam insulation has actually been around since the sixties, with foam still being a preferred product overseas. And it is one of the oldest insulation solutions in New Zealand. Its rediscovery and redevelopment came out of Director Chris Haughey’s frustration, followed by his dogged determination, to find a better product for New Zealand dwellings than what was currently available. He saw shortfalls associated with wool and fibre glass products. With a drive and passion for his business, he works alongside Rob Leach, who runs the operations, with a good, strong background team.
“Internal temperature is maintained for much longer, compared to other products,” he says. “Consumers have, until now, not had the choice and had to go with what was available.”
There is a complete moisture and air barrier which reduces the energy cost and reduced the dew-point on the skin of the building. The foam, once applied, is completely inert with no off-gassing, is chemically stable, and no formaldehyde is present. Made from recyclable materials such as recycled plastic bottles and 20% sustainable soy-based oil, the foam is completely self-extinguishing. Data sheets and fire tests have been incorporated as part of the Codemark industry standard. “It also boasts the highest thermal R-values on the market.”
No gaps or corners remain. As it is sprayed on, it can adhere to any curve, angle or corner, and it will never move or sag over time. Moisture and damp proof, it’s ideal for underfloor insulation on wooden floors. For walls or ceilings, it is also adhesive to concrete and steel, and is safe to use around wiring and plumbing. The thickness can be adjusted to suit the degree of insulation requirements for each project.
“No maintenance is required - its lifecycle cost is zero. We confidently offer a 25-year guarantee for the product to perform at an optimum level. It will last the lifetime of the building – only needing to be done once.” Even though foam looks good, for exposed ceilings or walls, it can be painted to colour-match the interior.
Nigel Reith of The Rakaia Hub’s potato storage facilities in Mid Canterbury, says the foam has economically transformed his business with this premium-grade insulation product, in regards to running costs and quality control.
“We go anywhere throughout the country,” says Chris. “It really is a great alternative product especially for big structures,”. From wineries to water tanks, options where the foam can be used are as flexible as the product itself.
“We supply the scaffolding and scissor lifts – there’s no building out of our reach. We also average 100sqm a day and the product dries in seconds, so down time is minimal.”
Well-recognised in Canterbury, home of NZ Foam’s headquarters, it now extends its installation nationwide, “its growth has been 10-fold - as there is nothing we can’t do,” he says confidently. “The new word in insulation has started to catch on - and that is orange.”
