Blanket Insulation
What Is Blanket Insulation?
Blanket insulation is the most common and widely available type of insulation. This type of insulation presents rolls or batts (pre-cut panels) made up of small fibers – fiberglass or mineral wool.
These insulation “blankets” are typically installed in floors, ceilings, and unfinished walls, including foundation walls. They can be easily fitted between studs, joints, and beams that are free from obstructions like ducts, wiring, or pipes. Blanket insulation is also commonly used as thermal insulation for areas inside the home, as well as acoustical insulation for retrofitting warehouses and other commercial buildings.
What Is Rolled Insulation?
Rolled insulation is a type of blanket insulation that comes in large continuous rolls that can be cut and trimmed to fit the area that needs to be filled. Rolled insulation can come with or without paper or foil facing, – the right insulation type would depend on where exactly the roll will be applied.

Common Blanket Roll Insulation Sizes
Fiberglass and mineral wool insulation rolls come in a range of thicknesses, R-values, and standard widths of 15’’ and 23’’. The dimensions of blanket insulation rolls are designed specifically to fit snugly into attics and cavities between wood framing, – plus, they can be cut to size when needed.
Benefits of Blanket Roll Insulation
Energy Efficiency
Properly installed blanked insulation makes homes more energy-efficient by preventing heat gain during summer and heat loss during winter. Reduced heat transfer, in return, leads to a more comfortable living environment and lower energy bills.
Soundproofing
Rolled insulation is excellent at absorbing sound waves, reducing noise pollution, and minimizing sound transfer between rooms.
Easy Installation
Rolled blanket insulation is relatively easy to install and is one of the most cost-effective options for both homeowners and builders.
Versatility
Rolled insulation can be installed in a wide range of spaces, including attics, floors, walls, and ceilings. Indeed, blanket rolls are a truly versatile insulation option.
Environmentally Friendly
Rolled insulation consists of materials like fiberglass or recycled denim, which makes it an excellent “green” option for environmentally-conscious individuals.
Which Is Better - Roll or Batt Insulation?
Both types of blanket insulation – rolled and batt insulation – are equally effective in improving the energy efficiency of your home and reducing the energy consumption associated with heating or cooling the property.
The main difference between the two insulation types is their form and method of installation. As such, rolled insulation is “rolled” between the studs or joints, while insulation batts are installed in pieces.
Types of Rolled Blanket Insulation
At Exotherm Spray Foam Systems, we offer two main types of rolled blanket insulation: fiberglass insulation rolls and mineral wool insulation rolls.
Fiberglass Insulation Rolls
Fiberglass insulation rolls are made up of fiberglass fibers that are spun together into a wool-like material. Fiberglass blanket insulation is relatively inexpensive and is often installed in floors, walls, and ceilings. Fiberglass rolls can be faced or unfaced, with kraft paper or foil facings available. Depending on the project at hand, faced insulation rolls may be preferred for their additional ability to reduce the amount of air that passes through the insulation.
Fiberglass Blanket Insulation R-Value
Similarly to fiberglass batt insulation, fiberglass insulation rolls may have different R-values, depending on the insulation thickness. The typical R-value of fiberglass insulation starts at R-3 per inch but can be increased by placing multiple layers of insulation blankets.
Mineral Wool Insulation Rolls
Mineral wool insulation rolls consist of natural or synthetic minerals like slag or rock. Mineral wool rolls also come in faced and unfaced varieties and are often installed in ceilings, floors, and walls. Mineral wool rolled insulation possesses excellent soundproofing properties, which makes it an excellent choice for areas like bedrooms or home theaters. Furthermore, mineral wool is fire-resistant and can withstand moisture, which makes it a great option for areas like kitchens and bathrooms. Because mineral wool rolled insulation can cost more than fiberglass insulation, it is not as commonly used and can be difficult to find in some areas.
Mineral Wool Blanket Insulation R-Value
The R-value of mineral wool roll insulation can vary depending on the thickness of the insulation blanket. Thinner blankets around 1’’ in thickness typically have an R-value of around R-4 per inch, while thicker blankets 6’’ in thickness can reach an R-value of R-24. When compared to the insulating properties of fiberglass rolls, mineral wool rolls are, without a doubt, superior: their R-value is 22% to 37% higher than that of fiberglass rolls.

Rolled Blanket Insulation FAQ
Blanket insulation is an excellent choice for reducing heat transfer and minimizing energy bills. Furthermore, it is budget-friendly and easy to install.
The optimal insulation choice would depend on the area that needs to be insulated. For instance, rolled or batt insulation is ideal for the construction of new walls, while existing walls may benefit more from blown-in insulation.
Spray foam insulation is often a better insulator than roll insulation, especially in tight areas where insulation blankets would be hard to fit. However, rolled blanket insulation in Toronto is a considerably more affordable option and is ideal for insulating unfinished walls, floors, and ceilings.
