Wall Insulation: Different Types of Insulation Material

Any insulating material connected to or put into walls is referred to as wall insulation. The primary role of insulating the wall is to improve the climatic effects of the area by making it easy to warm and cool. Also, effective wall insulation batts decrease undesired draughts, make interior temperatures more consistent, and significantly enhances air quality and humidity levels, reducing the chance of house sickness for the home’s owners and visitors. 

What Are the Different Types of Insulation You Can Install in Your Home?

For good wall insulation, many kinds of insulating materials are applied. They are as follows:

Rolls and Blanket Batts

Blanket batts and rolls are primarily composed of fibreglass; however, cotton, sheep’s wool, mineral wool, and plastic fibre varieties are also accessible. Because the materials are intended to suit the standard width between wall framing, installing this insulation is a low-cost and do-it-yourself task.


Blown-in insulation is a form of insulating material made of a paper-like substance that is professionally placed and mainly derived from eco-friendly recycled materials. It has the ability to expand and fill the space where it is placed, resulting in fewer gaps than batt insulation alone. It also performs incredibly well when combined with other insulation types, but excellent air sealing is required to avoid undesired leaks when used alone.

Furthermore, this sort of insulation is often constructed of fibreglass, rock wool, or recovered cellulose material, which conforms to almost any type of location—even the most challenging barriers. However, easy insulation work may be feasible if you hire an insulation blower, but consider hiring an expert for the most satisfactory results.

Foam Board or Rigid Foam Panels

If you need to insulate a wall, rigid foam panels and foam boards panels may help. They minimise the amount of heat carried through wood, wall studs, and other structural parts of a house. This form of insulation, which often consists of polystyrene, or polyurethane, is used by homeowners for exterior and interior wall coverings. 

Radiant Barrier or Reflective

Because radiant barriers or reflective functions differ from other forms of insulation, their efficacy is not assessed by R-values. Standard insulation restricts heat flow in a house, while reflective insulation reflects heat away from the building, preventing heat gain and radiant heat exchange to colder surfaces. Furthermore, a reflective barrier is put over a substrate material to provide insulation, such as polythene bubbles or kraft paper. Installation is also doable without the assistance of a professional.

Spray Foam

Spray foam insulation fills gaps and fixes leaks within existing walls. Liquid urethane is sprayed into the wall cavity, where it contracts and solidifies to form solid foam. When insulating a wider area, homeowners might select pressure sprayed insulation. Spray foam is also available in open-cell foam and denser closed-cell foam. Closed-cell foam insulation has the greatest R-value, about R-6.2 per inch of any insulation, but it is more costly. At the same time, open-cell foam insulation rates are approximately R-3.7 per inch of thickness. If you select spray foam insulation to boost the R-value of your home’s insulation, consider hiring a professional since installation might be more complex than just targeting and spraying.

What Should You Keep in Mind When Installing Insulation Walls?

Insulating a home’s walls should be considered from the start of the building or renovation phase. Ensuring that everything is done correctly might save you the trouble of dealing with any future difficulties.

Obtain The Right Dimensions

Insulation must be placed securely between joists. It is critical to precisely calculate an area’s length, breadth, and depth before putting it in. To fit any existing pipes or cables, adjustments may be required. Moreover, to get exact results, walls should be scrubbed clean of any previous materials.

Set In Position

Fasten the padding insulation in place over the appropriate place. A second roll may be required in certain spots to provide a thicker layer of protection. If spray foam is preferable, use it to fill open spaces. After all of these stages have been completed, drywall installation may begin.

Look For Oversights

Insulated walls are only as good as the foundation that holds them up. Owners and experts should search for air holes in unexpected locations. Spray foam may be used to cover pipe gaps, and high-temperature caulking can be utilised to encapsulate electrical outlets.

Select Good Materials

Understandably, builders and homeowners want the finest outcomes at the lowest possible cost. Fibreglass insulation is less expensive and causes minor irritation to individuals who come into contact with it. If fire safety is a crucial issue in the house due to extenuating conditions, cellulose may be a preferable alternative.

You can choose the best wall insulation for your requirements and budget with the guidance of experienced specialists. This means that the advantages and costs of each kind of wall insulation are set out before you, assisting you in making your selection.
