Spray Foam: a simple alternative to cold storage fees

In times like these, we’re all thinking about ways to make our businesses more secure and looking for ways to cut costs. Creating a cool store on your property might be simpler than you thought! NZ Foam has managed new cool store builds for growers – and also created cool stores from existing buildings.

 

NZFoam’s building blocks for better insulation:

Superior

Recycled an old chicken shed to become a viable cool store for his onions

“I had read about existing shed conversions using the unique insulating properties of foam. Two months after consultation, our cost-efficient, functioning operation was in full swing.”

Cost vs. Value: How does spray foam insulation weigh up?

THE VALUE OF SPRAY FOAM

  • Lifetime Warranty that is transferable to future home-owners
  • Will never sag, slump or move in the building cavities
  • Shown to reduce power bills by up to 40% compared to other insulation products
  • Highest R-Value achievable in the market

THE COST OF FIBREGLASS

  • A Warranty that is only valid for the installer and expires when the home is sold to the next buyer
  • Can sag, slump, move and decay over time, and be eaten by pests.
  • Has plenty of gaps allowing drafts and moisture to travel through buildings
  • Shown to have a lower R-Value once installed than what is advertised on the packaging

“Instead of a costly off-site storage facility, you pay the capital costs once and then that building can be useful all year round,” says NZ Foam’s Chris Haughey.

Chris has a building background and so he understands exactly what it takes to turn a shed into a coolstore – or build one from scratch.

“The key is to do it well, or it doesn’t add up. If your cool store isn’t protected from the rapidly fluctuating temperatures that we have in a lot of the country, then you’ll spend too much on cooling costs.”

NZ Foam’s spray foam insulation is thermally superior, ecologically and environmentally friendly.

Wire: Safe & Compliant

Is it ok for spray foam to be in contact with wiring or does the wiring need to be conduited? Like how polystyrene reacts with wiring insulation?

The issue with Polystyrene and TPS wiring is caused by the migration of plasticisers between the two products.

As spray foam has no plasticisers in the formulation there are no related issues.

We have a letter from General Cable confirming their findings.

 

So you’re saying you cant pull additional wiring through without opening up the wall and cutting it?

Due to the high R-value achieved we typically don’t need to fill the entire cavity – therefore there is normally a gap between the insulation and the internal linings. This allows for a draw wire to be used to retrofit wiring.

Also unlike other insulation products this process will not accidentally disturb the insulation therefore not compromise the thermal barrier.

You can add wires once spray foam is installed and linings on.

Not like most other insulation, where if you drill down the wall. Once you drill down the wool or Fireglass will wrap around the drill bite creating a cavity. Then you remove the drill pulling up the wool or Fibreglass and then creates another cavity.

Spray foam will not do any of these things. You drill a hole and push a wire down. Not affecting the integrity of the spray foam insulation.

Fire: Self-Extinguishing

Is spray foam combustible?

Technically, yes – it combusts at 408 degrees celsius!! 😉

Our foam meets all fire requirements under the building code and has been tested and complies with AS 1366.

How does spray foam rate in a house fire? When it burns, does it give off dangerous gases like polystyrene does?

Like all thermal insulation products, spray foam is combustible. This is why it’s compulsory to have a fire-rated lining such as a plaster board.

Spray foam insulation is known as a “self-extinguishing” product. If a fire source is introduced it will burn and char. If the source is removed the foam will no longer continue to burn.

Like most building products such as carpet, floor vinyl, furniture and even the timber framing; spray foam insulation will give off various gases such as carbon monoxide and hydrogen cyanide once the fire has reached the foam.

Normally by the time the fire actually reaches the foam, it is well established and the occupants have been evacuated.

Every home already has products like carpet, vinyl flooring, fibreglass batts, and various material furnishings that also give off toxic fumes if burnt. Our product is no more or less dangerous in this respect.

Human & Environment: Friendly

Is spray foam insulation bad for the environment?

Our product is made of 20% recycled content, can save homes up to 40% on their monthly energy bills, is non-allergenic, dust and fibre-free, and will last the lifetime of the building it is installed in to.

Compared to all other insulation products on the market, it is the most sustainable and has the smallest impact on the environment.

Does spray foam let off any odour or toxic gas long term?

No – once installed it is completely odourless.

Our spray foam insulation is also certified GREENGUARD Gold by global safety science leader, UL. Products that have achieved GREENGUARD Certification are scientifically proven to meet some of the world’s most rigorous third-party chemical emissions standards, helping to reduce indoor air pollution and the risk of chemical exposure.

You can view our GREENGUARD certificate here.

 

 

What is the form made up of?

Our spray foam has several main ingredients which have been chosen due to their quality and low environmental impact.

The main base product is oil. The oil is derived from two main source materials:
• Soya oil: Grown annually in arid areas and of no value as a food crop
• Recycled plastic: Mainly bottles, which make up over 20% of the product.

The final main ingredient is the hardener; which once combined with the other ingredients, is almost instantly transformed into a chemically inert, stable and PH-neutral insulation product that will not reduce in performance over the life time of the building.

 

The international Spray Polyurethane Foam Alliance has led our industry to accurately determine the environmental impacts of Spray Polyurethane Foam insulation materials.  In 2013, an industry-level, ISO-compliant life cycle assessment (LCA) was completed.  This study led to the development of environmental product declarations (EPDs).  Compliant with ISO requirements, this study was updated in 2018.

You can view the outcomes of these studies and read the technical aspects of spray foams environmental impacts here.
