Fiberglass Insulation: Fiberglass insulation is made of glass fibers that are spun into a fluffy material. It comes in rolls or batts and is often pink or yellow in color. It's a very common type of insulation because it's affordable and easy to install. It's typically used in walls, attics, and floors, and can also be used to insulate pipes and ductwork. Fiberglass insulation is available in different R-values (a measure of thermal resistance) and thicknesses to fit a variety of applications.
Cellulose Insulation: Cellulose insulation is made from recycled newspapers that have been treated with a fire-retardant. It's typically blown or sprayed into walls and attics and provides excellent thermal insulation. It's also a good choice for homeowners who are concerned about the environmental impact of their insulation. Cellulose insulation can be used to insulate both new and existing homes.
Spray Foam Insulation: Spray foam insulation is made from polyurethane and is sprayed into walls, floors, and ceilings.
It's an excellent insulation choice because it not only provides thermal insulation but also acts as an air and moisture barrier. This means that it can help keep your home more comfortable and energy-efficient. Spray foam insulation is available in two types: open-cell and closed-cell. Open-cell spray foam is less expensive and has a lower R-value, while closed-cell spray foam is more expensive but has a higher R-value.
Radiant Barrier Insulation: Radiant barrier insulation is typically made of aluminum foil and is installed in attics to help reflect heat away from the house. This type of insulation is particularly effective in hot climates because it can reduce the amount of heat that enters the home through the roof. Radiant barrier insulation is available in rolls and sheets and can be installed by a professional or a homeowner.
Reflective Insulation: Reflective insulation is similar to radiant barrier insulation, but it's made of a different material (usually aluminum foil). It's typically used in walls, roofs, and floors and is designed to reflect heat and keep the home cool in the summer. Reflective insulation is available in rolls and sheets and can be installed by a professional or a homeowner.
Mineral Wool Insulation: Mineral wool insulation is made from molten glass or rock that is spun into fibers. It's similar to fiberglass insulation in terms of its appearance, but it's denser and provides better sound insulation. Mineral wool insulation is typically used in walls, floors, and attics and is available in different R-values.
Polystyrene Insulation: Polystyrene insulation is made from polystyrene beads and is available in two types: expanded and extruded. Expanded polystyrene insulation (EPS) is less expensive and is typically used in walls, roofs, and floors. Extruded polystyrene insulation (XPS) is more expensive but provides better insulation and is often used in below-grade applications, such as basements.
Quebec has a cold climate with long, harsh winters and hot, humid summers, so it's important to choose insulation that will provide good thermal resistance and also help control moisture.
In general, it's recommended to have a minimum of R-50 insulation in the attic and R-20 to R-25 insulation in exterior walls for Quebec's climate zone. For floors, the recommended insulation level will depend on the construction of the floor, but it's typically recommended to have at least R-25 to R-30 insulation in floors above unheated spaces like basements.
Some recommended insulation types for Quebec include:
Fiberglass insulation: Fiberglass insulation is a common and affordable option that provides good thermal resistance. It's available in a range of R-values and can be used in walls, attics, and floors.
Spray foam insulation: Spray foam insulation is a popular choice for homeowners in Quebec because it provides both thermal insulation and an air barrier. This can help prevent air leakage and drafts, which are common problems in cold climates.
Cellulose insulation: Cellulose insulation is made from recycled newspaper and is treated with a fire-retardant. It's a good choice for homeowners who are concerned about the environmental impact of their insulation. Cellulose insulation can be blown or sprayed into walls and attics and provides excellent thermal resistance.
Mineral wool insulation: Mineral wool insulation is made from molten glass or rock that is spun into fibers. It provides good thermal resistance and also has good sound insulation properties, making it a good choice for homes that are located near busy roads or other noise sources.
Ultimately, the recommended insulation type and R-value will depend on several factors, including your budget, climate zone, and home construction. It's best to consult with a professional insulation contractor like SOS CONTRACTOR to determine the best insulation type and level for your specific needs.
