Foam insulation is a very important part of
insulating various parts of your home, in order
to make it as energy-efficient as possible. When
talking about foam insulation some people
picture the wrong thing in their minds. This is
not foam like the material that is in the seat
cushions of your couch and it is also not the
foam that fills the pillows on your bed.
This type of foam is much more rigid; in fact
it is commonly called rigid foam insulation or
rigid foam boards. The material used to make
this insulation is polystyrene. Polystyrene is a
thermoplastic substance which just means that
when it is heated it becomes a liquid and when
it cools off it becomes a solid again. This
property allows it to be molded into whatever
shape is needed.

There are two types of polystyrene foam
insulation: Molded Expanded Polystyrene (MEPS)
and Extruded Expanded Polystyrene (XEPS). You
really don’t need to know all the technical
differences other than the fact that XEPS is
somewhat more expensive than MEPS and it also
has a more consistent density. We are able to
install either type, and can make a
recommendation based on the characteristics of
your home.
Rigid foam insulation can be used in a variety
of places around the home:
- Roof – in fact, some rigid insulation
really is quite rigid – enough so that a man
can walk on it safely
- Foundation
- Overhead garage doors
- Water pipes
- Cathedral ceilings
- Walls – exterior walls can really be a
problem with letting cool air-conditioned
air out in the summer and allowing cold air
into the heated house in the winter. Rigid
boards of foam insulation can be cut to fit
precisely between studs to make sure that
doesn’t happen.
As you can see by the list above, the foam
insulation used in each
location would require a different shape. That
is the big advantage of this rigid material; it
can be formed to whatever shape is required.
A re-roofing is often a good time to consider
upgrading the energy efficiency of your roof
particularly if you have cathedral ceilings. The
rafter cavities above the ceiling are sealed on
both sides – the roof on the top and the
finished ceiling surface on the bottom. One of
those two surfaces has to be opened up in order
to retrofit rigid foam insulation and if the
roof is being torn off anyway that presents the
perfect opportunity to solve two problems at
once and not have to rip apart the ceiling from
the inside. If your home is more than about 20
years old, odds are it is a good candidate for
an energy efficiency upgrade.
Whenever we install polystyrene foam insulation
over a ceiling we make sure that the interior
side (the side that faces the ceiling) is
covered with a minimum of ˝ inch gypsum
wallboard. This is to serve as an added layer of
fire protection (and in fact is required by fire
codes). Some homeowners that attempt this kind
of work on their own are not aware of details
such as that and end up with a completed
project that is not only out of compliance but
one that also puts their family at a greater
risk of danger in case of a fire. We encourage
you to have a professional handle a job such as
this. All of our repair specialists are
certified technicians and they are highly
trained to analyze various heating and air
conditioning situations. They will advise you on
the best way to proceed and all of our work is
backed up by our company’s reputation and
warranties.
