Types of Insulation Materials
When insulating a suspended floor, there are several types of insulation materials you can choose from. Each type has its own unique properties and advantages. Here are some common types of insulation materials used for this purpose:
1. Foam Insulation Boards
Foam insulation boards are rigid panels made of polystyrene or polyisocyanurate. They are lightweight and easy to install, making them a popular choice for suspended floor insulation. Foam boards provide excellent thermal insulation and can help reduce heat loss and improve energy efficiency.
2. Mineral Wool Insulation
Mineral wool insulation, also known as rock wool or stone wool, is made from natural minerals such as basalt or diabase. It is available in the form of batts or rolls and has excellent thermal and acoustic insulation properties. Mineral wool insulation is non-combustible and provides good fire resistance.
3. Cellulose Insulation
Cellulose insulation is made from shredded newspaper or other recycled fibers treated with fire retardant chemicals. It can be blown or sprayed into the floor cavity, providing a seamless and effective insulation layer. Cellulose insulation is eco-friendly, as it is made from recycled materials, and offers good thermal and acoustic insulation.
4. Fiberglass Insulation
Fiberglass insulation is made from fine glass fibers and comes in the form of batts or rolls. It is a popular and affordable option for insulating suspended floors. Fiberglass insulation is lightweight, non-combustible, and offers good thermal and acoustic insulation. However, it can be irritating to the skin and respiratory system, so proper protective gear should be worn during installation.
5. Reflective Insulation
Reflective insulation consists of layers of foil or metallic materials, which reflect heat instead of absorbing it. It is typically installed with an air gap between the insulation and the floor, creating a radiant barrier.
