Different Types Of Insulation to Use In The Roof & Ceilings Of Your Home
Insulation is an essential component of any building, and it plays a significant role in maintaining the indoor temperature of a building. In a building, the roof is often the primary source of heat loss or gain, making it important to install proper insulation. Insulation materials come in a variety of forms, each with its own set of benefits and drawbacks. Below are some different types of insulation you can use in your home’s roof that can help ensure it is energy efficient.
Fibreglass is a popular choice for ceiling insulation due to its affordability and ease of installation. It is made of tiny glass fibres woven together to form a mat. It is commonly available in batts, rolls, and loose-fill forms. Fibreglass insulation can be installed on top of existing insulation or used as the primary insulation material. One of the key benefits of fibreglass insulation is that it is fire-resistant. It can also be used in areas with high humidity, as it does not absorb moisture. However, fibreglass insulation can cause skin and respiratory irritation if proper safety precautions are not taken during installation.
Spray Foam Insulation
Spray foam insulation is a popular option for roofs with irregular shapes or hard-to-reach areas. It is applied as a liquid and expands to fill the entire cavity. Spray foam insulation provides excellent thermal insulation and air-sealing properties. It can also help prevent moisture from entering the attic space. However, one drawback of spray foam insulation is its high cost compared to other types of insulation, and it can also be difficult to remove or replace if needed.
Cellulose insulation is made of recycled paper and cardboard, making it eco-friendly. It is available in a loose-fill form and is installed by blowing it into the attic space. One of the advantages of cellulose insulation is that it is highly effective at reducing air infiltration and heat transfer. You can also treat it with borate to prevent pests and mould growth. However, cellulose insulation can be a fire hazard if not treated with a fire retardant. It can also absorb moisture and become compressed over time, reducing effectiveness.
Mineral Wool Insulation
Mineral wool insulation is made of rock or slag fibres spun into a mat. It is available in batts, rolls, and loose-fill forms. Mineral wool insulation is highly effective at reducing noise transfer and has excellent fire-resistant properties, and it is also resistant to pests and mould growth. However, mineral wool insulation is heavier than other types of insulation, making it more difficult to install. It can also be more expensive than fibreglass insulation.
Radiant Barrier Insulation
Radiant barrier insulation is a reflective material installed on the underside of the roof. It works by reflecting heat back into the attic space, reducing the heat entering the living space. Radiant barrier insulation is most effective in warm climates where air conditioning is used extensively. One of the disadvantages of radiant barrier insulation is that it is less effective in colder climates. It also requires the proper installation to be effective, as gaps or seams can reduce effectiveness.
