What is Blown In Insulation?
A good solution to cut down heating bills is to use loose fill insulation that
can be blown into the walls. If they are well insulated, the house and the attic
will not lose heat to the outside. Because it is an easy process, you can decide
to install the blown in insulation by yourself or to ask the help of a
professional contractor.
Equipment for Blown In Insulation Installation
For installing blown in insulation, several tools and materials are required and
they are easy to find in specialized shops. The shopping list must include
loose-fill insulation material, expanding foam sealers, paint and dry wall
compound. Also, the tools needed for the operation include an insulation blower,
a hole saw drill bit, a stud finder, a drill, a step ladder, a wide putty knife,
a bread knife and a tape measure.
Installing Blown In Insulation
Installing blown in insulation requires several steps. First, find the right
spots to make holes in the walls by using a stud finder. Attention is needed
during drilling, though, as electrical wiring passes the walls near the floor.
Make the holes using a hole saw, keeping in mind to make them a little bigger
than the nozzle of the insulation blower. Once the holes in the walls are
finished, it is time to fill them. This step is done using the insulation blower
and the loose fill insulation material. After all the holes are full, they are
covered with expanding foam for sealing. There is a waiting time for the foam to
dry, but, after that, the job is almost finished. The exceeding foam that forms
outside the holes must be removed with a bread knife. After that, all that
remains to be done is to cover the walls with dry wall compound and paint.
Precautions for Blown In Insulation
As mentioned before, extra care is required during drilling the holes as there
are wires and pipes in the walls, especially in the kitchen and the basement.
Also, blown in insulation must not be installed near heating appliances or
chimneys as the materials used are inflammable. On the walls insulated with this
method, it is recommended to use a paint that absorbs moisture.
