Põrandaisolatsioon

Põrandaisolatsioon refers to the process of insulating floors in buildings. The primary purpose of floor insulation is to reduce heat loss, thereby improving the thermal comfort of the living space and decreasing energy consumption for heating. It also plays a role in preventing moisture issues and improving sound insulation.

There are several types of floor structures that can be insulated, including suspended timber floors, ground floors (concrete slabs on grade), and floors above unheated spaces like basements or crawl spaces. The specific insulation materials and methods employed depend on the floor construction and the desired performance level. Common insulation materials include mineral wool, polystyrene foam (EPS and XPS), and polyurethane foam.

In suspended timber floors, insulation is typically placed between the joists. For concrete slab floors, insulation can be laid beneath the slab or on top of it before the final floor covering is installed. In all cases, a vapor barrier is often incorporated to prevent moisture from migrating into the insulation layer, which could compromise its effectiveness and lead to structural damage. Proper installation is crucial for achieving optimal thermal performance and avoiding thermal bridging, where heat can escape through uninsulated gaps. Effective põrandaisolatsioon contributes significantly to a building's overall energy efficiency and occupant comfort.
