Dry Mortar for Insulation

Dry mortar plays a significant role in building insulation, enhancing both thermal and sound insulation properties. It is a versatile material used to create a protective layer that helps regulate temperature and reduce noise transmission within buildings.

Building Insulation with Dry Mortar

Thermal Insulation: Dry mortar is used in thermal insulation systems, such as External Thermal Insulation Composite Systems (ETICS). In this application, dry mortar serves as an adhesive and leveling layer for insulating materials like Expanded Polystyrene (EPS) boards. It creates a continuous thermal barrier that minimizes heat loss or gain, improving energy efficiency.

Sound Insulation: Dry mortar contributes to sound insulation by acting as a sound-damping layer. It is applied between walls, floors, or ceilings to reduce the transmission of airborne and impact noise. Dry mortar’s density and composition help absorb and dissipate sound waves, making it an effective soundproofing material.

Contribution to Sound Insulation

Reduced Sound Transmission: Dry mortar effectively reduces sound transmission by creating a dense, non-resonant barrier that prevents sound waves from passing through walls or floors.

Impact Noise Reduction: Dry mortar helps dampen impact noise, such as footsteps or structural vibrations, by absorbing and dispersing the energy generated by these sources.

Acoustic Comfort: Incorporating dry mortar into building insulation systems enhances occupants’ acoustic comfort, ensuring a quieter and more peaceful living or working environment.

Compliance with Building Codes: Many building codes and regulations require sound insulation measures in residential and commercial buildings. Dry mortar assists in meeting these standards by providing an efficient and cost-effective solution.
