The blow-in insulation technique involves blowing natural insulation material into spaces such as attics and wall cavities—that is, the empty spaces between solid structural elements. It can be applied from both the inside and the outside.
Insulating your home using the blow-in method is cost-effective, but it must be done by qualified technicians—such as the professionals at Bioisolare —using products with specific technical specifications and durability, such as Aerosilex Expanded Silicate Beads.
To blow-in the insulation into the wall cavities, holes are drilled at the top of the building’s exterior walls. To install insulation in attics, access is gained through existing hatches or skylights; if none are present, an opening is created from the outside of the roof.
Blown-in insulation: the benefits
Let’s now look at some reasons to insulate your home using Aerosilex blown-in insulation —expanded silicate beads from the Bioisolare S system:
- The material fills the cavities perfectly and provides complete insulation.
- The procedure is minimally invasive: even when performed from the outside, it does not alter the appearance of the facade.
- It is eco-friendly thanks to the material used (Aerosilex) and because it helps reduce CO2 emissions
- This insulation project eliminates heat loss and reduces condensation and moisture.
- It is also an excellent sound insulator.
- Installation takes very little time: the work can be completed in a single day.
- The material is also certified for green building; it acts as a fire barrier because it is inert and fire-resistant (Class A1), and it is mold-resistant and antibacterial.
- The Bioisolare S system can be used for blow-in insulation in both new and older buildings (from the 1950s and 1970s), as well as in wooden structures and buildings still under construction.
Air injection is a good choice: effective and affordable
Blown-in insulation is effective because it helps reduce energy costs for heating and cooling buildings. It also helps eliminate heat loss and condensation, and improves the comfort of your home. Furthermore, blown-in insulation requires a smaller investment than other types of insulation.
How long does the air injection last?
This insulation system lasts practically as long as the house itself and requires no maintenance. Over time, in fact, the thickness of the material remains stable: it does not diminish but stays the same, ensuring perfect insulation both in summer and winter, forever.
