Unveiling the Best Loft Insulation Options: Why Recycled Polyester Loft Insulation Tops the List

Creating a comfortable, energy-efficient home is a priority for every homeowner. One of the key ways to achieve this is through effective loft insulation. With a multitude of options available in the market, making the right choice can be a daunting task. This comprehensive guide aims to explore the best loft insulation options available, with a special focus on why recycled polyester loft insulation stands out as the superior choice.

Understanding Loft Insulation

Loft insulation is a material that is placed in the loft or attic of a home to slow down the transfer of heat between the inside and outside of the house. It works by trapping pockets of air within its structure, reducing the rate of heat conduction and helping to maintain a consistent temperature within the home.

Exploring the Options

There are several types of loft insulation available, each with different properties and benefits. These include:

  1. Fibreglass Insulation: A popular choice, fibreglass insulation is lightweight and affordable. However, it can irritate the skin and lungs if not handled with care.
  2. Mineral Wool Insulation: Known for its fire-resistant properties, mineral wool insulation is denser than fibreglass, providing excellent insulation. However, it can be a bit pricier than other options.
  3. Cellulose Insulation: An eco-friendly option, cellulose insulation is made from recycled paper products. While it's a great choice for the environmentally conscious, it can settle over time, reducing its effectiveness.
  4. Spray Foam Insulation: Spray foam insulation offers excellent heat resistance and is perfect for filling gaps. However, it's one of the more expensive options and usually requires professional installation.
  5. Polystyrene Insulation: Polystyrene insulation is lightweight and water-resistant, making it ideal for areas exposed to moisture. However, it's not as eco-friendly as some other options.

The Superiority of Recycled Polyester Loft Insulation

While all the above options have their merits, recycled polyester loft insulation stands out for several reasons:

  1. Environmentally Friendly: Recycled polyester loft insulation is made from recycled polyester, primarily from plastic bottles. This not only reduces waste but also decreases reliance on non-renewable resources.
  2. Safe to Handle: Unlike fibreglass and mineral wool, recycled polyester doesn't irritate the skin or lungs, making it safer to handle and install.
  3. Excellent Thermal Performance: Recycled polyester provides excellent thermal resistance, helping to keep your home warm in winter and cool in summer.
  4. Long-Lasting: Recycled polyester is resistant to pests and mould, ensuring it maintains its performance for many years.
  5. Easy to Install: This insulation comes in rolls, making it easy to cut to size and install between rafters.


While there are many types of loft insulation available, recycled polyester loft insulation stands out for its environmental benefits, safety, thermal performance, durability, and ease of installation. By choosing this type of insulation, you're not only creating a comfortable home but also contributing to a more sustainable future.
