Different Types of Insulation

Different materials can be used to insulate buildings. Choosing the best material depends on the specific needs of the end-user, as they have very different characteristics.

Different Materials and Their Purposes

Fibre blankets and rolls are an inexpensive and easy method of insulation. They are fitted between wall beams when there is sufficient room for them.

Concrete blocks are more efficient in moderating indoor temperatures. They also require space and need more specialised skills to incorporate into a wall.

Plastic foam boards and rigid plastic foam are an excellent choice when there is not much space inside the wall. They provide high efficiency, but the insulating layer is relatively thin. They require more work to make them weather and fireproof.

Insulating concrete forms or ICFs are also made of plastic foam boards or foam blocks. They are incredibly efficient, but they must be incorporated into a wall during the building process. It is not possible to add them later on or during a renovation.

Loose-fill and blown-in insulation made of minerals, fibres, or cellulose are an efficient solution to already finished walls. They are incorporated into smaller spaces and enclosures within finished areas. They fill cavities and complement existing insulation solutions.

Another way to complement existing insulation is the sprayed foam. Plastic or cement foam is applied using a foamer or spray machine with high pressure. It is possible to use them as a part of a renovation, but not as a stand-alone solution to insulation.

Structural insulated panels or SIPs are a relatively recent and highly efficient innovation in insulation technology. SIPs consist of foam boards that can be fitted into walls by construction workers. They are used in renovations and building new walls, but not for renovating finished walls. SIPs offer unmatched efficiency compared to traditional insulation solutions and are relatively easy and quick to integrate into walls.
