Ceiling insulation can make a huge difference to the energy efficiency of your home or office, helping you save money on heating and cooling bills. In addition, ceiling insulation can help block outside pollutants that enter your space through air gaps. This can reduce radon and other harmful gas emissions, as well as mold growth.
Insulation can come in various forms, including loose-fill, batts, rolls, foam board and spray foam. It’s important to understand the differences between each of these types so that you can choose the right one for your home or business.
Loose Fill Insulation
The most common type of insulation is loose-fill, which can be made from cellulose (made from recycled newspapers), fibreglass, rock wool or mineral wool. These materials can be blown into tight spaces and cavities using a blowing machine.
Loose-fill insulation is often more affordable than other insulation products, but it also requires special equipment for installation. This can increase the overall cost of the project and may be less practical in difficult-to-access areas.
Blown-in Insulation
Another popular type of ceiling insulation is blown-in, which is often made from fiberglass, cellulose or rock wool. It is blown in with a special machine, and it can be installed by homeowners or professionals.
Rolls and Batts
Rolls and batts are similar to loose-fill insulation, but they can be rolled into smaller pieces, which makes them more efficient for installing. They are available in a variety of lengths and thicknesses, and they can be used for walls, floors and ceilings.
They can also be cut to fit joists, which can be particularly useful for vaulted ceilings. They are easy to apply and typically have a low moisture content, which makes them resistant to mold and mildew growth.
Fiberglass Rolls
Unlike batt insulation, which are installed in small pieces, rolls are rolled out between the framing of a wall or ceiling to provide an even insulation level across the entire surface area. These insulation rolls are often more effective than batts and can be used to insulate unfinished walls, ceilings and basements.
Foam Boards and Radiant Barriers
Known for their high R-values, foam boards are a great choice for insulating the roof, exterior walls and interior sheathing of a home or building. They can also be used in a variety of special applications, like attic hatches and walls with low-sloped ceilings.
Icynene Spray Foam
Among the many types of insulation, spray foam is perhaps the most effective at controlling heat flow and reducing energy loss. It offers a high R-value and can be installed in a closed-cell or open-cell structure, depending on the application.
It can prevent condensation and mould growth, which can cause problems with a ceiling, such as rotting or affecting the configuration of your home. It is also extremely durable, and will not sag or settle over time.
The key to a successful insulation project is sealing air gaps and ensuring that the material you use forms a snug fit with the joists. This ensures that your insulation doesn’t leak out of those tiny gaps and cracks, which can let in cold air and warm air from the outdoors.
