Blanket Insulation for Commercial Establishments: What Is It And How Does It Work?

08 May 2023

Blanket or batt insulation is a thermal insulation commonly used in commercial buildings. It is made from flexible fibres, such as fibreglass, rock wool, or mineral wool, designed to fit between the studs and joists of walls, floors, and ceilings.Blanket insulation is an affordable and effective way to increase the energy efficiency of a commercial building. Properly installed blanket insulation can reduce energy costs and improve the overall comfort of the building’s occupants.

What is Blanket Insulation?

Blanket insulation is a type of insulation that is manufactured in rolls or batts. It is designed to fit between the studs and joists of walls, floors, and ceilings. It is typically made from flexible fibres, such as fibreglass, rock wool, or mineral wool.

Blanket insulation is commonly used in commercial buildings because it is easy to install and is available in various sizes and R-values (a measure of thermal resistance). R-values range from R-11 to R-38, with higher values indicating better insulation.

Benefits of Blanket Insulation

Blanket insulation offers numerous benefits to commercial establishments. Here are some of them:

Thermal Protection

One of blanket insulation’s most significant benefits is its superior thermal protection. This means that it helps maintain a consistent temperature within the establishment, which can save money on heating and cooling bills.

Acoustic Insulation

Blanket insulation can also help reduce noise levels within the establishment. This can be particularly beneficial in noisy commercial environments like manufacturing facilities or restaurants.

Fire Protection

Blanket insulation is also an effective fire retardant. It can help prevent fires from spreading, protecting your establishment and its occupants.

Environmentally Friendly

Many blanket insulation products are made from recycled materials, making them an environmentally friendly option for commercial establishments.

Blanket Insulation Variants

In the Australian construction industry, batts and rolls can be purchased in various standard widths. The dimensions of the blankets allow them to be tucked in between trusses and rafters in the attic, floor joists, and wall studs. Continuous insulating rolls have the advantage of being able to be cut and trimmed to fit most different-sized spaces.

Rolls and batts of blanket insulation can come with or without facings, depending on the product. Insulation blankets with facings can be more easily handled and fastened, in addition to extending the efficiency of the insulation.

Facings also have the potential to perform the function of a radiant barrier, resulting in increased thermal resistance. We might utilise insulation with protective features like a vapour barrier or an air barrier, depending on our working location. There are other batts available that have additional facings that are flame resistant.

Insulation removal is messy and labour-intensive; therefore, engaging a professional familiar with the process and who possesses the necessary training and tools are in your best interest. You run the danger of getting sick and contaminating the air in your home over the long term if the blanket insulation is infected with mould or has been invaded by pests.

Insulation R-Values

In regions that do not have numerous impediments (pipes, wires, etc.), between joists, studs and beams, ceilings, floors, new construction projects, and unfinished walls, blanket insulation is frequently employed (including foundation walls).In addition to its usage as a thermal and acoustical insulator in residential and commercial structures, blanket insulation is typically the material of choice when it comes to insulating attics. Blanket insulation can be purchased in rolls.

Heat constantly travels from warmer parts to colder areas, whether you are heating or cooling the space. It flows through the inner walls, ceilings, and floors—anywhere there is a temperature difference that has to be stabilised—as it makes its way through the building.
R-values evaluate how well insulation can be a thermal barrier against heat flow. If your insulation has a higher R-value, it will perform better, and you will see more cost savings on your monthly heating and cooling expenses.

The R-value of fibreglass blanket insulation is contingent on several variables, the most important of which is its thickness. Insulation blankets have an R-value that ranges from around R-2.9 to R-3.8 per inch. R-values that range between R-3.7 and R-4.3/inch can be found in high-performance fibreglass blankets and batt insulations.


Blanket insulation is an effective way to provide thermal, acoustic, and fire protection for commercial establishments. Choosing the right insulation with the appropriate R-value, material, and fire rating can help create a safe and comfortable environment for your employees and customers.
