How should floors be properly insulated?

Insulating floors can provide a number of benefits for homeowners. First and foremost, properly insulated floors can help reduce energy costs by up to 20%. This can be especially beneficial in colder climates, where heating costs can be quite high. Additionally, insulating floors can help maintain a more consistent temperature throughout the home. Finally, properly insulated floors can increase the value of a home due to its energy efficiency.

Materials used to insulate floors

When it comes to the materials used for floor insulation, there are several options available. The most common material used is expanded polystyrene (EPS) insulation. Another option is the use of PUR polyurethane foam, whose boards are laid directly, as with other thermal insulation materials, on top of the moisture barrier placed on top of the first structural concrete of the floor.

PUR insulation foam is a slightly more expensive material than the popular Styrofoam, but it provides better insulation, so you can use a thinner layer of insulation (PUR-100mm = EPS~160mm). Also, the durability of PUR foam and resistance to, for example, rodents, or unfavorable conditions such as moisture, affects the long-term profitability of using this material in construction work. However, it is important to carry out the necessary work properly and with high-quality insulation materials.
