Blown-in insulation for attics and crawl spaces that lasts a lifetime
Blow-in insulation is a technique that provides thermal insulation for buildings by filling existing cavities between walls, accessible and inaccessible attics, and roof cavities with a specific insulating material. At Bioisolare, we perform insulation work using the Bioisolare-S system, which involves blowing in Aerosilex S (expanded silicate beads). The term “blow-in insulation” refers to the fact that the material is inserted by blowing (insufflating) it into the selected area, creating a breathable thermal barrier for the building. The material is forced into the space under pressure using a specialized system. Insulation Installation Timelines Insulation installation via blowing is highly advantageous because it can be completed very quickly by expert companies like Bioisolare. Just consider that a medium-sized apartment (80–120 square meters of floor space) can be insulated in a single workday. We can proceed with the thermal insulation of attics or wall cavities in both homes undergoing renovation and occupied homes, without causing any inconvenience to the residents. When can blow-in insulation be performed? Blow-in insulation can be performed if there is a cavity in the exterior walls: the material is inserted through holes drilled at the top of the walls from the inside or outside, depending on the needs and preferences of the home’s occupants. In addition to blowing insulation into cavity walls, as mentioned, the work can also be performed in accessible and inaccessible attics. A technician will physically enter the attic through an internal hatch or existing skylight, or by cutting a hole in the roof, which will be sealed once the work is complete. Furthermore, for the insulation of new buildings, Aerosilex-S can be blown in during roof installation, creating a layer of material that immediately improves the building’s insulation properties. Durability and Long-Term Stability The insulation materials that remain most stable over time are granular materials, such as Aerosilex, expanded silicate beads, because they do not deform in the presence of moisture, water, or weight. Consider, for example, a glass filled with sand: if it is not knocked over, the glass will remain full and in the same condition forever. Aerosilex is a safe material; it does not burn and poses no risk of ignition even if placed near a chimney. It offers a good balance between mass (weight) and insulating capacity, making it ideal for thermal insulation in the summer. The installed thickness does not decrease over time, and its composition contains no harmful substances. The insulation performance achieved through the blow-in technique using Aerosilex S – Expanded Silicate Beads – is therefore guaranteed for several decades: at Bioisolare, we use only high-quality insulation material and carry out the work with experience and expertise.
