Removing Insulfluf: Why It’s Time for a Change in Your Home

Insulation plays a critical role in keeping your home cosy and energy-efficient. Insulfluf was a popular solution for many homes built in the 1970s and 80s. This cellulose-based insulation, made from recycled paper products, was considered innovative and eco-friendly. However, decades later, Insulfluf often poses more challenges than benefits. If your home still relies on this outdated insulation, it’s time to consider a change. Here’s everything you need to know about Insulfluf, why removing it is essential, and how Absolute Energy can help.
What is Insulfluf?
Insulfluf, or Insulfluff, is loose-fill cellulose insulation made primarily from recycled paper products like newsprint. With a recycled material content of 82% to 85%, it was an environmentally friendly option during its heyday. The material was installed by being blown into roof cavities, creating a tightly packed layer of insulation designed to minimise heat loss and improve energy efficiency.
Its affordability and ease of installation made it particularly popular in South Island homes during the 1970s and 80s. Insulfluf provided an effective thermal barrier that was both sustainable and practical at the time, helping homeowners reduce energy costs while repurposing waste paper materials.
Why Was Insulfluf Popular in Its Prime?
In an era when home energy efficiency was becoming a priority, Insulfluf offered an accessible solution. The product’s loose-fill nature allowed it to conform to the nooks and crannies of roof cavities, ensuring comprehensive coverage and reducing heat transfer. Additionally, its recycled content appealed to homeowners who were conscious of their environmental impact. Combined with its low cost compared to other insulation materials, Insulfluf quickly became a standard choice for South Island homes.
For decades, Insulfluf provided adequate insulation. But, like many materials, it wasn’t designed to last forever. Over time, the insulation has faced various issues that make it less effective and potentially harmful to today’s homeowners.
The Downside of Aging Insulfluf
While Insulfluf was a great option when first installed, time has exposed some significant drawbacks. Here’s how Insulfluf deteriorates over time:
Settling and Compaction
Insulfluf tends to settle and compact as the years go by, reducing its insulating properties. Instead of forming an effective barrier, the material becomes denser and less capable of trapping heat, leaving homes colder and less energy-efficient.
Dusty and Dirty Environments
Over time, the cellulose material can break into fine particles, creating a dusty environment in the roof cavity. This diminishes insulation performance and can circulate dust throughout the home, potentially triggering allergies or respiratory issues.
Vermin Contamination
Insulfluf is prone to becoming a breeding ground for vermin. Rodents can nest in the material, leaving faeces and urine contaminating the insulation. This poses health risks and creates unpleasant odours.
Moisture Issues
In some cases, Insulfluf can absorb and retain moisture, leading to mould growth and further compromising its performance. Prolonged exposure to dampness can even damage the structural integrity of your home’s roof cavity.
Why Removing Insulfluf is Essential
If your home still has Insulfluf installed, removing it is essential to improve your living environment. Here are the key reasons to consider removal:
- Improved Energy Efficiency: Old and compacted Insulfluf no longer provides the insulation your home needs. Replacing it with modern insulation can significantly improve heat retention and lower energy bills.
- Health and Safety: Dust, vermin contamination, and potential mould growth can negatively impact indoor air quality and pose health risks to you and your family.
- A More Comfortable Home: Without adequate insulation, homes with ageing Insulfluf are often cold and damp, especially in South Island winters. Removing and replacing the material ensures a warmer, drier living space.
Absolute Energy’s Solution for Removing Insulfluf
Removing Insulfluf is not a DIY project. Due to the dusty nature of the material and the risk of contamination, it’s a job best left to professionals. Absolute Energy offers a specialised Insulfluf removal service designed to handle the process safely and efficiently.
Safe and Thorough Removal
Absolute Energy uses industrial-grade vacuum systems to extract Insulfluf from your roof cavity. This ensures minimal dust and disruption to your home while effectively removing all traces of the old insulation.
Replacement with Modern Insulation
Once the Insulfluf has been removed, Absolute Energy can install high-performance insulation tailored to your home’s needs. Modern insulation materials are far more durable, efficient, and resistant to settling, ensuring long-term benefits for your home.
Health-Conscious Approach
By removing contaminated insulation and replacing it with clean, effective alternatives, Absolute Energy helps create a healthier indoor environment for you and your family.
