Top 15 Best Cheapest Insulation Options in 2024

The best cheapest insulation is not only going to save you money in the long term but also increase energy efficiency and make your home eco-friendly. This Pricewise blog will cover the importance of the best cheapest insulation, the benefits of affordable insulation options and how to choose the right insulation needs for your property.

What Are The Benefits Of Insulation?

Energy Efficiency

Insulation contributes to energy efficiency because a home that has been well-insulated will significantly reduce cooling costs during summer and heating bills during winter.

Quality insulation provides considerable resistance to the heat flow that enters and leaves your home, which means you get to enjoy the comfort of adequate room temperatures all year round.

Cost Saving

With an increase in energy costs, Australians are trying to find ways to reduce household energy consumption. 

Research shows that a home that has been fully insulated will reduce heating and cooling costs by approximately 40-50%. This means that, on average, Australian households have saved up to $1,561 a year by adding insulation and fixing draughts.

Environment Friendly

Here at Pricewise, quality insulation will not only help you save money in the long term but will also reduce your reliance on fossil fuels and reduce greenhouse gas emissions.

Pricewise recommends products such as Earthwool Insulation because it is easy to install, contains no added formaldehyde and is environmentally friendly. Insulation can also reduce a home’s carbon footprint.

How to Choose the Right Insulation for Your Home

Considering Your Climate

Before purchasing insulation, find out what climate zone you are in. Each climate zone across Australia has been determined by factors such as average temperatures, rainfall and humidity. Your climate zone will help you identify the correct level of R-Value insulation. 

Understanding Your Home’s Needs

Before undergoing your home insulation project, it is important to know the age of the property, as some insulation products are not suitable for a retrofit. Insulation may already exist in some parts of your home, and the R-Value is going to help you save on energy costs and help protect the environment.  

Talk to one of our leading experts today and choose the right insulation for your project.

Budgeting for Insulation

Quality insulation can save you money in the long term, increase energy efficiency and help protect the environment. Insulation products that have a high R-Value may cost more initially, although over time will contribute to energy cost savings.

Making Insulation Affordable: Tips and Tricks

DIY Installation: A Cost-Effective Option

DIY installation can be a cost-effective option, although it is important to consider the risks and hazards that may also be involved. For example, checking the local building code for R-value is correct and allowing for clearance around appliances and fittings. Using insulation products such as glasswool and natural wool batts are generally safer to work with and can be easily installed.

Hiring a trained professional provides a warranty on the workmanship and a guarantee that regulatory standards have been followed. However, this can be a costly option. Choosing to install the insulation yourself will save you money and the Pricewise team is available to offer support and guidance where needed. Government grants or rebates may also be available under the local climate and energy action scheme.
