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.”
