Your property’s insulation is the first step towards comfort and well-being. It plays a key role in achieving a high-efficiency building. It is important to consider the physical, economic and ecological benefits of good insulation.
Depending on your project, several insulation products are available on the market. The main ones are:
Mineral wool (rock or glass)
Closed cell sprayed polyurethane foam
Mineral wool is a good thermal insulation and, depending on the type of wool, it can also be a good acoustic insulation. The wool has the advantage to better fill the spaces between the beams of an attic and is easy to handle in restricted places.
On the other hand, in the occurrence of water infiltration, it tends to absorb it. When installed in the walls, it can collapse. When laying mineral wool, you should ideally have gloves and a mask in order to avoid breathing suspended particles. Wool is not recyclable, but reusable if it has not been in contact with water or other liquids.
Closed Cell Sprayed Polyurethane Foam
Closed cell polyurethane spray foam is a good insulator to seal cracks and fill uneven spaces such as crawl spaces or stone walls.
This insulation method should ideally be applied by a professional, as risks of an improper and/or inefficient application are quite high. This foam is non-recyclable. However, according to the manufacturer, it can be partly made from recycled materials.
Extruded polystyrene (XPS) is a thermal insulation in the form of rigid boards. It can insulate almost any flat surface of a building. Its R factor is one of the best on the market.
However, this type of insulation is more expensive than other rigid boards options. Moreover, its manufacturing method is not the most eco-friendly. Also, it is important to note that it is difficult to use on uneven surfaces.
Expanded polystyrene (EPS) is an excellent thermal insulation method. Sold in rigid boards, it can insulate almost any building surface. Its R factor is also one of the best on the market. EPS insulating boards can be laminated with an air barrier or vapor barrier. They are easy to install and handle. Composed of 98% air and 2% material, they are 100% recyclable and usually contain a portion of recycled material.
However, this type of insulation has no acoustic properties and is more difficult to use on uneven surfaces.
Whether you are looking into insulation a new construction or to renovate, insulation will provide you with an economical advantage by lowering energy costs and adding more comfort! This important step should not be abandoned.
