There are several types of insulation materials that can be used in a loft or attic space to improve energy efficiency and regulate temperature. The choice of insulation depends on factors such as budget, local climate, and personal preferences. Here are some common types of loft insulation:​

​

Fiberglass Insulation

 

Fiberglass insulation comes in rolls or batts and is made from fine glass fibres. It is a popular choice due to its affordability and effectiveness.

Pros: Good thermal performance, fire-resistant, easy to install.

Cons: Can cause skin irritation, requires protective clothing during installation.​

 

Cellulose Insulation

 

Cellulose insulation is made from recycled paper or cardboard treated with fire retardants. It can be blown or sprayed into the loft space

​Pros: Environmentally friendly, good thermal performance, effective in reducing air leakage.

Cons: May settle over time, may be more expensive than fiberglass.​

 

Mineral Wool Insulation

 

Mineral wool insulation, such as rock wool or slag wool, is made from natural or synthetic minerals. It is available in batts, rolls, or loose-fill form.

Pros: Fire-resistant, excellent thermal performance, resistant to pests.

Cons: Can be heavier and more expensive than fiberglass.​

 

Spray Foam Insulation

 

Spray foam insulation is applied as a liquid that expands into a foam, creating a tight seal. It can be made from polyurethane or other materials.

Pros: Provides an airtight seal, high R-value (thermal resistance), water-resistant.

Cons: More expensive, may require professional installation, may release toxic fumes during application.​

 

Expanded Polystyrene (EPS) Insulation

 

EPS insulation, commonly known as beadboard, is made from expanded polystyrene beads. It is available in rigid panels or boards.

Pros: Lightweight, good thermal performance, resistant to moisture.

Cons: May not provide as high an R-value as some other materials.​

 

Reflective Insulation

 

Reflective insulation usually consists of a reflective foil facing that reflects radiant heat. It is often used in combination with other insulation materials.

Pros: Reflects heat, effective in reducing radiant heat transfer.

Cons: more expensive, requires professional installation. Professional advice and installation may be recommended, especially for certain types of insulation like spray foam.
