Why Insulate with Wool

  • Why imitate what Mother Nature has perfected?
  • It is a completely natural product.
  • Wool is a strong durable fibre that will last for many years to come.
  • Wool absorbs moisture from the air reducing condensation and the growth of mould or mildew in the home, which can trigger asthma or allergic reactions.
  • Wool is a breathable fibre, absorbing and evaporating moisture, thereby creating a natural air-conditioning effect.
  • Wool creates a thermal barrier – perfect for the Central Otago climate, keeping you warm in the winter months and cooler in the heat of the summer.
  • Wool has acoustic absorbion properties, reducing noise transmission through the home.
  • Wool is kind to your health… it is hypoallergenic, non-toxic and absorbs pollutants, which may be present in your home.
  • Wool is eco-friendly, as it is a naturally renewable resource and biodegradable.
  • Wool has low embodied energy, meaning it requires very little energy to produce it.
  • Wool is naturally fire retardent, making it a safe insulating option.
  • Supports NZ farmers and the economy.

Heat Loss

In a non-insulated building, research illustrates the average heat loss at various exit points:

Ranking Exit points Percentage

It is staggering to see how much heat can be lost if you are not sufficiently insulated, and the most obvious place to start improvements is the ceiling. An insulated building is more energy efficient and healthier place to live, than a non-insulated building.

Downlights are also a common place for heat to escape, so it’s a good idea to replace these with conventional lights where possible.

If your insulation was installed over 10 years ago, or your property was built before 2007, its time to have your ceiling insulation assessed.

"Great people to do business with. Very pleasant, reliable, efficient and tidy operators who carried out their work when they promised. We found the Shear Comfort wool insulation extremely clean and quick to install with no glass fibres floating in the air or drifting around the house in our retrofit case. It also saved our house from destruction in a recent electrical fire in the ceiling."
