How Much Does Insulation Cost in Canada?
For reference purposes only, here’s a pricing table detailing the different types of insulation materials sold in Canada.
Insulation Type | Price Per Sq. Ft./Rooms | R-Value Per Inch * |
Expanded polystyrene (EPS) | $1.5–$4 | 3.9 |
Extruded polystyrene (XPS) | $3–$4 | 3.6 |
Closed-cell polyurethane spray foam | $2.50–$8 | 3.2–5 |
Open-cell polyurethane foam | $3–$5 | 3.2–5 |
Polyisocyanurate (PIR) | $1.50–$3 | 6 |
Ecobill MD/® (polystyrene microbeads) | $2–$4 | 4.4 |
Soybean oil-based foam | $3–$6 | 6 |
$2.50–$3 | 2.8–4.5 | |
Fibreglass | $1.60–$2 | 3–4.5 |
Cellular glass | $3–$5 | 2.6 |
Cellulose | $1.48–$2 ** | 3.6 |
Hemp | $1–$4 | 3.7 |
Straw bale | $5–$18 ** | 2 |
Cotton | $1.50–$3.50 | 3.8 |
Cork | $2.50–$6.50 ** | 3.7 |
* The R-value measures the material’s insulation effectiveness.
** Insulation costs vary depending on the material’s form (panel, bulk, batt, etc.), area to be insulated (exterior wall, attic, floor, etc.), product on which the insulation material will be installed (brick, wood, etc.), and labour costs.
Affordable Options
Fibreglass
Fibreglass is an easy insulation material to install, providing moderate fire resistance. However, it’s not waterproof, which can lessen its efficiency if exposed to humidity. Moreover, it may contain formaldehyde, meaning this material mandates special care during installation.
Cellulose
Cellulose makes for an effective flame-, mould-, and corrosion-resistant choice, providing good soundproofing properties. However, installation can be complex and said material is moisture-sensitive. For optimal performance, cellulose insulation typically needs to be thicker, although it doesn’t significantly affect cost.
Expanded Polystyrene (EPS)
Expanded polystyrene (EPS) is a moisture-resistant insulator with decent thermal protection. It’s easy to install and is often used for a myriad of construction-related installations. However, in case of a fire, EPS can release toxic fumes, which calls for special attention to safety when installed in buildings.
Polyisocyanurate (PIR)
Polyisocyanurate (PIR) provides excellent flame, moisture, and water resistance, which makes for a solid insulation choice. However, it loses its insulation properties when directly exposed to cold air. Moreover, its installation requires precautionary measures to ensure maximum effectiveness.
Hemp
Hemp is a flame-, bacteria-, insect-, and fungi-resistant insulation material. It also has good soundproofing properties, which makes it a versatile and sustainable choice for a myriad of insulation purposes.
Cotton
Cotton is flame-resistant and has good soundproofing properties. However, it's moisture-sensitive, which can compromise its efficiency when exposed to humid conditions.
Standard-Priced Options
Extruded Polystyrene (XPS)
Extruded polystyrene (XPS) is a reputable insulator known for its moisture resistance, making it ideal for humidity-exposed installations. It’s easy to install, whether it’s for renovations or new constructions. However, note that XPS isn’t fireproof and may release toxic fumes if exposed to open flames, which calls for cautionary use in buildings.
Open-Cell Foam
Open-cell polyurethane foam is airtight, which further contributes to its decent thermal insulation. However, it’s not as effective when exposed to moisture and has limited fire resistance. These characteristics make its use preferable in settings where product limitations are manageable.
Ecobill MD/® (Polystyrene Microbeads)
Polystyrene microbeads used to make Ecobill/MD® provide sprayed-in insulation that doesn’t require demolition, allowing walls the breathe while preventing mould growth. It’s a clean, dustless, and odourless material that boasts reclaimable and recyclable benefits. However, it’s not waterproof nor draft-proof and may release toxic fumes during a fire, similar to other expanded polystyrene-based insulators.
Rockwool
Rockwool is an effective insulator that’s both fire- and moisture-resistant, while also providing excellent soundproofing properties. It’s easy to install and versatile for a myriad of construction types. However, note that it may contain formaldehyde, meaning this material mandates special care during installation.
Cellulose Glass
Cellulose glass is airtight and moisture-proof, with decent flame resistance and a long service life. It also has effective soundproofing properties. However, its insulation capacity is typically weaker compared to other insulation materials.
Soybean Oil-Based Foam
Soybean oil-based polyurethane foam is an effective insulator that’s airtight and moisture-resistant, with a great expansion capacity for optimal coverage. However, handling requires specific protection to ensure a safe installation.
Cork
Cork is water-, fire-, insect-, and rodent-resistant. It also provides decent soundproofing. However, it calls for a thicker layer, typically between 8–12 inches, ensuring optimal performance.
Closed-Cell Polyurethane (Spray Foam)
Closed-cell polyurethane is great given its airtight and water-resistant properties. However, it’s not fireproof and rather complex to install, requiring professional help to ensure optimal efficiency.
High-End Option
Straw Bale
Straw-insulated panels are fire-resistant and provide decent moisture resistance. However, the panels have to be between 14–18 inches thick, and the home in question must have been built according to specific constraints to be effective. Given said prerequisites, straw bales are often used for new construction rather than during remodelling or renovation efforts.
What Factors Affect the Cost of Upating Your House’s Insulation?
Type of Insulation Material
The selected insulation material will affect the overall project cost. There are several different insulation options, with unique price ranges and advantages. Ultimately, your decision will hinge on factors like budget, desired insulation level, and the targeted areas to insulate.
Square Footage to Insulate
The square footage to insulate will directly affect the overall cost. The bigger the targeted area, the higher the insulation cost will be. Moreover, area accessibility will also be factored in when calculating costs.
Installation Complexity
Installation complexity affects house insulating costs. Hard-to-reach areas, such as narrow spaces or high ceilings, are more time-consuming and demanding, increasing costs. If you’re replacing your old insulation material, the removal process can also incur more costs. Moreover, ensuring an airtight seal during the installation process is paramount to maximize insulation efficiency, albeit doing so may incur additional fees.
Labour Cost
Unless you plan on heading the DIY route when insulating your house, you’ll have to hire local insulation contractors. Hiring experts guarantees proper installation, which, in turn, optimizes energy efficiency and long-term savings. Furthermore, hired professionals can help you choose the best materials suited to your specific needs, ensuring your home remains at comfortable temperatures and is properly insulated year-round.
Our Tips for Making a Well-Informed Decision
To properly insulate your home in 2024, it’s essential to understand the different options made available. Whether opting for affordable materials, such as fibreglass or cellulose or selecting more effective solutions, such as polyurethane or cork, every option has its upsides and drawbacks. In a nutshell, choosing the right insulator depends on your budget, project specificities, and the sought-after thermal efficiency.
FAQ

Fibre-reinforced concrete was a definite turning point in the construction industry. Designed to offset the brittleness of standard concrete and with a low-tensile strength, fibre-reinforced concrete sets a new record. As a result, some mixtures allow for fewer rebar use on construction sites since this material can withstand tensile forces of 2,300 MPa, compared to standard concrete’s 500 MPa.
