Selecting the appropriate attic insulation is a crucial choice that homeowners frequently must make when starting house renovations. This decision is important for home comfort, energy efficiency, and health and safety, whether you’re installing ceiling insulation or loft insulation. Our experts will compare different attic insulation choices and their advantages and downsides to help you make an informed decision.
Types of Attic Insulation Material
The best type of insulation for an attic refers to the different materials it comes in, each with special advantages and disadvantages. Choose the right attic insulation material from fiberglass, foam, cellulose, and reflective systems to reduce energy costs, environmental impacts, and indoor climate.
Fiberglass
Fiberglass is often selected for attic insulation due to its cost-effectiveness and fire resistance. Available in rolls or batts, it’s a practical choice for budget-conscious homeowners who may prefer to install it themselves. While it offers extra fire security, the installation process can be hazardous to your health due to loose fibres that can irritate the skin and lungs, necessitating protective gear. Over time, fiberglass can settle, compromising its insulative properties, and its propensity to absorb moisture can lead to mould problems, diminishing its effectiveness.
Cellulose
Cellulose insulation is favoured for its excellent thermal performance and soundproofing abilities, owing to its dense composition of recycled paper products. It is environmentally friendly and treated with fire retardants for added safety. Despite its superior insulation capabilities, cellulose can be costlier than fiberglass and often requires professional installation. It’s also heavier, which may demand structural considerations for some attics, and like fiberglass, it is susceptible to moisture, leading to decreased efficiency and mould issues.
Mineral Wool
Mineral wool, known for its fire resistance and acoustic dampening properties, is derived from natural minerals or metal waste products. It is denser than fiberglass and cellulose, providing a high level of sound insulation and maintaining its shape and effectiveness over time without settling. Its moisture-resistant nature makes it less prone to mould growth, ensuring a consistent R-value. The main drawbacks include its higher cost and weight, which could necessitate structural reinforcement, and the challenge of installation due to its density.
Cotton
Cotton insulation, often made from recycled denim, stands out for its environmental sustainability and ease of installation, as it does not require special safety attire. It offers good sound insulation and does not irritate the skin or lungs. However, cotton insulation can come at a higher cost. It may not provide as high an R-value per inch as other materials, which could be a deciding factor for thermal efficiency needs.
Foam
Spray foam insulation provides an advanced, high-R-value option that excels in air sealing, potentially significantly reducing energy loss. Its ability to fill gaps and conform to space makes it versatile for various attic shapes and sizes. Spray foam also adds structural strength to the roof. However, this type of insulation carries the highest cost and requires professional installation. The chemicals in its composition call for careful consideration of its environmental impact.
