The Most Popular Insulation Types Among Warmer Kiwi Homes Grant Beneficiaries

You're in luck if you've considered boosting your home's cosiness and energy efficiency. Thanks to the Warmer Kiwi Homes Grant, many have made their homes snugglier with top-notch insulation. 

Would you like to know more about the insulation options available under the Warmer Kiwi Homes Grant NZ? Stick around as we dive into the most popular insulation choices for those looking to make their homes more energy-efficient, especially if you're eyeing the grant. Let's get into it!

Fibreglass Insulation

Fibreglass insulation is popular in New Zealand due to its excellent thermal performance, fire resistance, and sound absorption. It is available in various forms, such as batts, rolls, loose-fill, and rigid boards. 

It is known for its environmental aspects, often containing recycled glass, making it an eco-friendly option. It is also moisture-resistant, easy to install, and cost-effective, helping homeowners reduce energy bills. Additionally, it can help improve indoor air quality by reducing mould and mildew growth.

This insulation is a versatile option for home areas such as attics, open walls, and crawl spaces. It is also available in blanket form, which is usually referred to as batts. We advise working with a professional installer to ensure a seamless installation process.

Mineral Wool Insulation

Mineral wool, including rock or slag wool, is a prevalent insulation type known for its high R-value, fire resistance, and soundproofing properties. Compared to fibreglass, mineral wool has a higher R-value per inch (about 22-37% higher) and superior sound-deadening properties. It is hydrophobic and won't absorb water or encourage mould and mildew growth. 

However, it tends to be more expensive than fibreglass, often between 25-50% higher in cost. Mineral wool is also easy to measure, fire-resistant, and does not absorb moisture, making it immune to mould. 

It is an environmentally friendly material and enhances comfort and well-being in buildings. Regarding insulation value, mineral wool has higher insulation values than fibreglass, and it fits into building practices with no need for extensive retraining or changes to new subcontractors or suppliers. 

Cellulose Insulation

Cellulose insulation is made from recycled paper and is known for its environmentally friendly nature and affordability. It provides good thermal performance, effectively reduces air infiltration, and has excellent soundproofing qualities. 

Using non-toxic fire retardants like borax makes it a safe choice for buildings. However, one of the drawbacks of cellulose insulation is its relatively lower R-value compared to other insulation types. 

On average, cellulose insulation costs $0.60 to $2.30 per square foot, making it an affordable option for homeowners. It is a smart and eco-friendly choice for those looking to insulate their homes effectively using sustainable materials.

Polyester Insulation

Polyester insulation, made from synthetic fibres, offers a durable and eco-friendly solution for keeping homes warm in winter and cool in summer. It's non-toxic and hypoallergenic, making it a safe choice for families and those with allergies. Its ease of installation and resistance to moisture and pests make it a reliable and maintenance-free option for Kiwi homes seeking efficient thermal performance.

GreenStuf® polyester insulation is an eco-friendly, durable, and high-performing option that complies with fire safety regulations, has a 50-year warranty, and is resistant to moisture, mould, mildew, insects, and vermin. It's also user-friendly, easy to install, and free from added chemicals like formaldehyde, ensuring safe indoor air quality.

This product is eco-friendly, made with at least 45% recycled polyester, and fully recyclable. It supports local industry and has been recognised by Asthma New Zealand as a safe choice for insulating homes, especially for those with asthma concerns.

Factors Influencing Insulation Choice Among Grant Beneficiaries

The factors influencing insulation choice among Warmer Kiwi Homes subsidy beneficiaries, such as cost, R-value, environmental impact, and home requirements, are crucial in the insulation selection process. 

Each home has unique needs, and a tailored approach is essential to make the right choice. Insulation materials have distinct advantages and performance characteristics, making selecting the right one based on specific needs and requirements crucial. 

Factors such as thermal conductivity, density, thickness, cost, durability, fire resistance, and environmental impact should be considered when choosing the best insulation material for a project. 

Additionally, greater thermal insulation values (R-value) and the reduction/elimination of toxins and volatile organic compounds are important sustainability considerations when selecting insulation materials. It is also essential to consider the environmental impact and the unique conditions of each building when choosing insulation materials.
