What is brick or masonry wall insulation?

Insulating a brick or masonry wall improves a building’s energy efficiency by reducing heat loss in winter and preventing heat penetration in summer. This helps maintain a comfortable indoor temperature, reduces energy consumption for heating and cooling, and saves on energy costs. Here are the main methods used to insulate a brick or masonry wall:

Thermal insulation: Thermal insulation is the main component of insulating a masonry wall. 

Insulation installation: Insulation is usually installed between the masonry walls or on the outside of the wall, depending on the insulation method chosen. Common methods include:

• Insulation from the inside: Insulation boards or wool are fixed to the inside of the wall, then covered with plasterboard or other wall finishes.
• Insulation from the outside: Insulation is installed on the outside of the masonry wall, then covered with siding (e.g. wood, metal or vinyl siding).
• Insufflation: Loose-fill insulation is blown into the wall cavities.

Thermal bridges: It’s essential to take steps to avoid thermal bridges, i.e. areas where heat can escape more easily. Thermal bridges can occur at junctions between walls, floors and windows. They can be reduced by using continuous insulation materials and careful installation.

Vapor barrier: In cold climates (like Quebec, for example), a vapor barrier can be installed on the warm side of the insulation to prevent moisture from penetrating the wall and causing humidity problems.

Ventilation: Adequate ventilation must be maintained to prevent moisture build-up inside the wall, which can damage both masonry and insulation.

What are the main materials used to insulate a brick or masonry wall?

• Mineral wool (rock wool or glass wool)
• Expanded polystyrene (EPS)
• Extruded polystyrene (XPS)
• Polyurethane (PU)
• Wood-fiber panels
• Polyisocyanurate foam (polyiso)
• Cellulose
• Vapor barrier
• Ventilation

Why is it important to insulate a masonry wall?

• Energy efficiency: Properly insulating a masonry wall helps reduce heat loss in winter and prevent heat penetration in summer. This helps maintain a comfortable indoor temperature and reduces energy consumption for heating and cooling. 
• Indoor comfort: Proper insulation helps regulate the temperature inside the home, creating a more comfortable indoor environment all year round. It also helps reduce temperature variations and draughts.
• Reduced energy costs: By reducing dependence on heating and cooling, good insulation delivers significant savings on energy costs in the long term.
• Durability: Insulation helps protect the building structure by reducing the risk of condensation and damp. This can extend the life of building materials and reduce long-term maintenance costs.
• Respect for the environment: Better insulation reduces energy consumption, resulting in lower greenhouse gas emissions and a smaller environmental footprint. 
• Compliance with building regulations: In many regions, building regulations require a certain level of thermal insulation performance to guarantee occupant comfort and safety. 
• Property value: A well-insulated building can have a higher resale value, as potential buyers appreciate the energy savings and comfort it offers.
• Noise reduction: Thermal insulation is often combined with acoustic insulation, which can help reduce exterior and interior noise, improving the quality of life inside the building.
