Insulation is an essential part of the home, as it helps to regulate the temperature and reduce energy consumption. This is the case even more so with roofs, where 25% of the building’s heat is lost. There are two main types of insulation used in residential roofs: blown-in insulation and batt insulation. Here, we will examine the pros and cons of each type to help you decide which is the best solution for their roof.

Blown-In Insulation

Blown-in insulation, also known as loose-fill insulation, is composed of small chunks of either fibreglass or cellulose that are blown into the space to be insulated. The material is blown out of the hose of a blowing machine, making it easier to cover all gaps than with some other types of insulation.

Composition

Blown-in insulation is typically made of recycled materials like cellulose and fibreglass. 

Environmental benefits

Blown-in insulation is considered to be better for the environment than batt insulation. It is composed mainly of recycled materials, and it can be reused or recycled after it has served its purpose. This makes it an eco-friendly option for those looking to reduce their carbon footprint.

Ease of installation

Blown-in insulation requires a professional to install it, as it requires specialist equipment. However, once the equipment is set up, the process is relatively quick and straightforward.

R-value

The R-value of blown-in insulation depends on the thickness of the layer installed. However, it generally has a higher R-value per inch than batt insulation.

Cost

Blown-in insulation is typically more expensive than batt insulation, due to the cost of the equipment and the need for a professional to install it.

Batt Insulation

Batt insulation, also known as roll insulation, is composed of large blankets of insulation that are made from either fibreglass or cotton. These blankets are cut to fit the space to be insulated and are installed between the studs or joists of the roof.

Composition

Batt insulation is typically made of either fibreglass or cotton. Both materials are readily available and relatively inexpensive.

R-value

The R-value of batt insulation depends on the thickness of the layer installed. If perfectly installed, batts give the better R-value.

Installation process

Batt insulation can be installed by homeowners themselves, making it a more cost-effective option. However, it requires careful handling during installation to ensure that there are no gaps or spaces where heat can escape and reduce the effectiveness of the insulation.

Cost

Batt insulation is typically less expensive than blown-in insulation, as it does not require specialised equipment or professional installation.

Comparison between Blown-In Insulation and Batt Insulation

Efficiency

Blown-in insulation is generally more efficient than batt insulation, as it is easier to cover all gaps and spaces in the insulation. Batt insulation, on the other hand, can leave gaps and spaces where heat can escape if not installed perfectly.

Effectiveness

Both types of insulation are effective at regulating temperature and reducing energy consumption. However, blown-in insulation has a higher R-value per inch, meaning that it can provide more insulation in the same space.

Cost

Batt insulation is typically less expensive than blown-in insulation, as it does not require specialised equipment or professional installation. However, blown-in insulation may be more cost-effective in the long run, as it provides better insulation and can help to reduce energy bills.

Environmental impact

Blown-in insulation is considered to be better for the environment than batt insulation, as it is composed mainly of recycled materials and can be reused or recycled after it has served its purpose.

 

In conclusion, both blown-in insulation and batt insulation are effective solutions for regulating the temperature within your home and reducing energy consumption. 

 

Blown-in insulation is generally more efficient and eco-friendly, but it is also more expensive and requires professional installation. Batt insulation is more cost-effective and can be installed by homeowners themselves, but it may not provide as much insulation as blown-in insulation. 

 

Ultimately, the choice between the two types of insulation depends on your specific needs and budget.
