Knowing how to insulate attic flooring is a
useful skill and effective fitting will ultimately save energy by reducing the
amount heat that is lost through the roof. Following a few simple steps will
enable you to undertake the task yourself so that you can save even more money.
Step 1 – Measure Dimensions
In knowing how to insulate attic flooring
properly, you must also know the dimensions of the area you will be working on.
To make sure that you get the correct amount of insulation material for the
job, you should carefully measure the relevant area.
This process will also allow you to examine the
attic floor to determine whether any rectification work is required before
insulation can take place. Look for any gaps or cracks in the flooring that may
cause the insulation to become less effective. Decide whether loose or rolled
insulation is more suitable for your individual needs.
Step 2 – Preparation
After gathering all the necessary tools and
materials, the process of insulating the attic flooring can continue by
correctly preparing the space. Move any portable items away from the area and
clean the attic of any dust and debris. Apply caulk to any sites that require
repair. If the light in the attic is insufficient to work in, put some
temporary lighting in place before you begin.
Many types of insulation contain materials that
can irritate the skin and respiratory system, so it is important to protect
yourself with overalls, gloves and a face mask.
Step 3 – Lay Insulation
For rolls of insulating material, begin at the
outer wall and lay the moisture barrier down against the floor surface. Tuck in
the edges of the material against the joists and unfurl it along the space
between them. Without stretching it, carefully pass the insulation beneath any
power cables so that neither suffer damage. If the roll is longer than the
space, use a pair of scissors to cut it before tucking all the edges against
the joists. Continue in this manner throughout the attic and don’t forget to do
the same with the top of the access hatch. Ensure that you leave a gap of at
least three inches between the insulation and any lighting fixtures to
eliminate fire risks.
If the joists in your attic are of a sufficient
height and there is not a whole house fan in place, loose insulation can be
appropriate. Pour the loose material over the attic floor so that it is as even
as possible. Use a gloved hand to spread the material beneath cables and pipes.
This will not be appropriate for the top of the access hatch, so attach a piece
of blanket insulation instead.
