Unravelling the Different Types of Loft Insulation: A Comprehensive Guide

When it comes to maintaining a comfortable temperature in your home, roof insulation plays a pivotal role. It acts as a barrier, preventing heat from escaping during winter and keeping your home cool during summer. But with a plethora of insulation types available in the market, making the right choice can be overwhelming. This blog post aims to shed light on the different types of roof insulation, helping you make an informed decision.

  1. Fibreglass Loft Insulation: A popular choice among homeowners, fibreglass insulation is made from fine strands of glass. It's often found in blanket form, known as batts or rolls. Its affordability and ease of installation make it a go-to option for many. However, it's worth noting that fibreglass can irritate the skin and lungs if not handled with care. So, always ensure you're equipped with the right safety gear when installing.

  2. Mineral Wool Loft Insulation: If you're looking for a fire-resistant and soundproofing insulation option, mineral wool, also known as rock wool or slag wool, is a great choice. Made from rock and other raw materials, it's denser than fibreglass, providing excellent insulation. However, it can be a bit pricier than other options.

  3. Cellulose Loft Insulation: For the environmentally conscious, cellulose insulation, made from recycled paper products, is an excellent choice. The paper is chemically treated to make it fire-resistant, making it safe for home use. It's typically blown into cavities, providing comprehensive coverage. However, it can settle over time, which may reduce its effectiveness.

  4. Spray Foam Loft Insulation: Spray foam insulation is a modern solution that offers excellent heat resistance. It's sprayed into place where it expands and hardens, filling gaps and cracks. This makes it perfect for irregularly shaped areas. However, it's one of the more expensive options and usually requires professional installation.

  5. Polystyrene Loft Insulation: Polystyrene insulation comes in two forms: expanded (EPS) and extruded (XPS). Both are lightweight and water-resistant, but XPS is more durable and resistant to compression. This insulation type is ideal for areas exposed to moisture.

  6. Recycled Polyester Loft Insulation: An emerging player in the insulation market, recycled polyester loft insulation, is made from recycled polyester, primarily from plastic bottles. It's environmentally friendly, safe to handle, and offers excellent thermal performance. Plus, it's resistant to pests and mould, ensuring it maintains its performance for many years.
