Insulating a New Building with Blown-In Cellulose Insulation

Insulation has a direct impact on a building’s energy efficiency, operating costs, and indoor air quality throughout its entire lifespan. For this reason, the insulation of a new building should be carefully planned and properly installed during the construction phase.

Blown-in cellulose insulation provides highly effective thermal protection because it fills structural cavities seamlessly and without gaps, eliminating thermal bridges and ensuring a uniform insulation layer throughout the building envelope.

Attic and Roof Insulation

For insulating pitched roofs and attic spaces, Ekovilla has developed a specialized cavity insulation system. Following the installation guidelines, the contractor prepares enclosed cavities that are then densely filled with insulation material by a qualified professional.

This solution allows complex roof structures to be insulated quickly and efficiently, reducing the risk of installation errors commonly associated with traditional insulation methods.

When the structure is prepared according to the installation instructions, the entire attic insulation process can be completed in a single operation. For enclosed cavity applications, the use of experienced insulation contractors is strongly recommended. The recommended insulation density for these applications is approximately 45 kg/m³.

Floor Insulation

Floor insulation is an important factor affecting both the energy efficiency of a building and overall living comfort. Ekovilla blown-in insulation is particularly well suited for insulating ventilated floors, suspended timber floors, and crawl-space floor structures, as it adapts perfectly to the construction, filling all gaps and creating a continuous layer of insulation.

The breathable nature of blown-in cellulose insulation helps regulate moisture levels within the structure while reducing heat loss through the floor. As a result, it can contribute to lower heating costs and provide a warmer, more comfortable floor surface.

Renovation and insulation with blown-in wool

Blown-in wool is an excellent solution for additional building insulation because its fine structure allows it to easily penetrate the structural cavities of a home. This insulation is characterized by low air permeability, which helps reduce convective air currents that cool down the structure. For this reason, blown-in wool is well suited, among others, for insulating unused summer cottages.

Eco wool (eco-wadding) protects wooden structures by regulating the moisture level within the material. Its vapor permeability makes it an ideal solution for insulating wooden buildings, which is why it is also commonly used in historic buildings and properties of high cultural value.

Additional insulation of the attic (upper floor ceiling)

Additional insulation of the upper floor with blown-in wool is easy to carry out and can be done at any time of the year. The more varied and irregular the substrate, the better the Ekovilla solution performs.

The insulation can be applied over existing layers, such as mineral wool insulation or other thermal insulation materials. Professionally installed additional insulation is quick and effective, and its results are durable and uniform.

Additional insulation of the lower floor

Blown-in wool is an excellent solution for additional insulation of, for example, floor joists (Rossi base) from the interior side. Additional insulation eliminates, among other things, air leaks typical of older buildings at the junction between the external wall and the lower floor.
