If your home isn’t properly insulated, heat will escape, and cold, damp air will seep in. This can lead to higher energy bills, a less comfortable living environment, and a larger carbon footprint. To help you understand the essentials, this guide covers the basics of building insulation.

What Is Building Insulation?

Building insulation helps prevent heat loss, making it one of the most effective ways to improve energy efficiency in homes, businesses, and industrial spaces. By reducing heat transfer, insulation keeps indoor temperatures comfortable year-round—cool in summer and warm in winter. This not only lowers energy consumption but also cuts down on utility costs.

Where Should You Install Insulation?

Proper insulation can transform draughty old houses into cosy, energy-efficient spaces. Here are the key areas where insulation can make a big difference:

1. Unfinished Attics

Loose-fill insulation is commonly used in empty attics. Properly insulating this space helps maintain a stable indoor temperature, reducing energy costs and enhancing comfort.

2. External Walls

For existing homes, contractors often drill small access holes (inside or outside) to inject insulation into cavity walls. Blown-in insulation is a popular, less invasive method that improves warmth and efficiency without major disruption.

3. Basement Walls

Before insulating basement walls, ensure they are completely dry to prevent mould and water damage. Adding insulation to interior basement walls improves warmth and protects against structural and weather-related issues.

How Much Does Building Insulation Cost?

Several factors influence the cost of insulation:

  • Type of insulation – Materials vary in price and performance.

  • Location of the property – Labour and material costs are typically higher in cities compared to rural areas.

  • Size of the area – Larger spaces require more materials and labour.

While urban areas may have steeper prices, investing in quality insulation pays off in long-term energy savings.

Key Considerations Before Insulating Your Home

To get the best results from your insulation, keep these points in mind:

1. Choosing the Right Material

Different materials—such as mineral wool, cellulose, fibreglass batts, and multifoils—have unique benefits and drawbacks. Select one that suits your climate and budget.

2. Proper Installation Matters

Poorly fitted insulation won’t perform effectively. If you’re unsure, consult a professional to ensure correct installation and follow safety guidelines.

Final Thoughts

Building insulation is a smart investment for a healthier, more energy-efficient home. Whether you’re tackling an old property or a new build, the right insulation approach can enhance comfort and reduce costs. By keeping these tips in mind, you can make informed decisions and achieve the best results.
