Why should you install home insulation?

Home insulation is one of the most effective ways to maintain warmth and reduce dampness in kiwi homes, reducing heat loss by up to 35%*. This energy-efficient solution keeps homes dry and warm in winter and cool and comfortable in summer. Insulation plays a crucial role in maintaining a comfortable and energy-efficient home, creating healthy home environments for Kiwi families.

Did you know that proper insulation can significantly improve the comfort and energy efficiency of your home? Unfortunately, many homes experience issues such as heat loss, cold drafts, and excessive moisture due to inadequate insulation.

In order to address these problems, it is crucial to invest in effective and sustainable insulation solutions. By insulating your home, you can create a barrier that helps to retain heat during the colder months and keep your home cooler in the summer. Additionally, insulation plays a key role in preventing moisture buildup, which can lead to mould and structural damage if left unaddressed.

Healthier Homes
By reducing the risk of mould, mildew, and allergens, proper insulation helps maintain consistent humidity levels and prevents drafts, creating a more comfortable and healthful space.

Home Comfort
With proper insulation, your home becomes more comfortable to live in as the temperature stays consistent and drafts are minimised.

Energy Efficient
Insulation acts as thermal barriers, helping to keep your home at a comfortable temperature by trapping heat inside during the winter and keeping it out during the summer. This means that you will use less energy to heat or cool your home, resulting in lower energy bills.

How does home insulation work?

Insulation acts as a barrier to heat flow, reducing the transfer of heat by trapping air particles. This slows down the flow of heat through your homes ceilings, walls and floors, holding warmth and helping your home stay warm in the winter and cooler in the summer.

Are EnergySmart's insulation products environmentally friendly?

Absolutely - EnergySmart uses Eco Insulation and Terra Lana insulation products. Both brands use sustainable manufacturing and eco-friendly materials.

How can I tell if my home insulation needs to be updated or replaced?

If your home is hard to heat or cool, has rising power bills for no obvious reason, feels damp, or shows signs of mould, draughts, or cold floors, your insulation may need replacing. Homes built before the 2000s often have old or degraded insulation that no longer meets current standards, especially if it’s been affected by moisture or pests. EnergySmart can provide a professional assessment to confirm whether your insulation is still effective and if an upgrade would improve comfort, energy efficiency, and health.

Does installing quality insulation improve your homes health?

Installing quality insulation can significantly improve your home’s health. Good insulation helps keep your home warmer and drier by reducing heat loss and condensation, which lowers the risk of dampness and mould growth. A warmer, drier home supports better respiratory health, especially for children, the elderly, and people with asthma or allergies. It also creates a more comfortable living environment year-round by maintaining stable indoor temperatures and reducing draughts.
