Blown in insulation is also known as loose fill insulation. This is the best way to insulate any existing structure as well as for additional insulation.
In this, loose particles are blown either into an attic or into the wall cavities between the interior as well as the exterior walls of the building. It is best to get the installation of blown in insulation done by a professional, as there has to be an even distribution of these loose particles.
The basic types of blown insulation would include fiberglass, mineral types and cellulose. This classification is based on the kind of material being used. Fiberglass remains the most common. In this case the insulation includes small particles that are made of spun glass fibers. In case of mineral wool type of blown in insulation, there are particles made of rock or steel slag. Cellulose insulation would include particles made of recycled newspaper or cardboard treated with chemicals in order to be resistant to flames as well as pests.
The insulation will be higher when this material is installed, and become less with time as the material settles down.
There are many advantages of using blown in insulation. A few of these are detailed below:
– It is highly economical as compared to other forms of insulation.
– It is easy to install, especially in the hard-to-reach areas.
– You can work around obstacles including chimneys or even stove vents.
– This is an eco-friendly option as recycled material is being used.
– You may use it either as your primary insulation, or add it to the existing insulation for filling in gaps or providing an additional form of heat barrier.
There are some disadvantages as well to blown in insulation. But with proper care, these can be removed or reduced to a great extent.
The particles tend to settle over a long time. This will reduce their thermal resistance. Therefore areas with blown in should be inspected on a yearly basis to make sure that there is proper insulation. Over time, this blown insulation may enter the living space as there are always gaps in the ductwork. This can lead to inhalation dangers of these fine particles. In order to avoid this, ensure a proper installation done by a professional. Your blown in insulation will have a tendency to absorb moisture. In order to counteract this, always use a vapor barrier, especially in case of a new installation.
In fact, blown in insulation is the only way for you to insulate your existing, and closed-up walls.
You can choose the insulation material depending on your needs. In case of cellulose blown in insulation, shredded newspapers that have been treated with fire retardant are used. Cellulose tends to settle much better into the wall cavities.
In case of mineral fibers blown in insulation, the materials used are fiberglass and rock wool. Thus, it is a more expensive option than using cellulose. But it is much lighter than cellulose. It can stand up to moisture and will not rot.
Blown-in insulation is typically used in attics. It is important to make sure your attic has sufficient insulation in order not to lose any energy within any season ,.
