the pitfalls of attic insulation is described in the given slides the history of attic insulation is explained in http://kimtan12.livejournal.com/1102.html

2. Purpose of insulation
Insulation is not confined to single purpose called energy
saver, there are some other purposes like
1. pest control
2.noice control
3.radient control
4. temperature control

3.  These are some basic advantages of insulation,
the evolution of insulation since early BC shows,
how welcomed by human kind.
 Despite the positive fact, there are some pitfalls
which are the deciding factor of the type of
insulation.
 Such drawbacks are discussed in the further
slides

4. Types of insulation
There are three major type of insulations
used since early days
1. fiber glass insulation
2. cellulose insulation
3. foam insulation

6. Common pitfalls, insulations
hold
Affordability is more
Periodical maintenance
Health issues
Installation cost is more

7. Cellulose insulation
 The material used in cellulose insulation is
made of recycled paper, so it is eco-friendly
 The rigidity of cellulose insulation, made it
suitable for all the parts of house, including
flooring, roofing, side walls, etc…

8. Pitfalls of cellulose
insulation
 Since the molecules materials are loosely
arranged, they are bad resistant of
moisture and water
 The recycled paper holds very light
weight. So they absorb the moisture at
faster rate.

9.  Cost wise it is average but comparatively,
it is higher than fiber glass insulation.
 This parameter made people hesitate to
opt for cellulose insulation
 It also causes serious health trouble
when less immune people get exposed.

10.  The materials used in cellulose should be
tight to restrict house from very gold or hot
climate.
 But when installed beyond certain limit, it
causes poor air circulation within the house
 Ventilation-less house is major threat to our
lives.

11. Fiber glass insulation
 This type of insulation came after the
asbestos insulation, which is first
insulation introduced by Greek people.
 It doesn’t require complex raw materials
for the manufacturing process. it can be
made with simple and instant materials
like plastics, glass materials, atc…

12. Pitfalls of fiberglass insulation
 This type of insulation holds the major
disadvantage called size.
 It is available in limited size, so it is unfit
for some part of the house.
 Since, this is old method, it is not suited
for the upgraded present architecture

13.  As the atoms in the fiberglass are loose,
the moisture content can easily enter
space between roof and the insulation
which in turn makes the material weak
within short duration.
 Dumping of more stuffs in one place also
leads to major problem.

14.  Moderate amount of insulation should be
used.
 More insulation will not provide way for
the rodents and noise from entering but
the lacks in ventilation, which some time
causes serious threat
 Too low insulation wont stay for longer
duration.

15. Spray foam insulation
 Spray foam insulation is in the
blooming stage, as it overcomes
some of the disadvantages of the
above two insulation process.
 It is the best air sealer, as the foam
used here seals each and every
corner.

16. Pitfalls of foam insulation
 The main disadvantage is
usage of light weight materials
 When installing, the foam flies
and get catch up with the
metal body around, which then
causes additional cleaning
work

17.  Cost wise it is more
expensive than other two
types.
 As the spray foam
insulation is the advanced
method and the materials
used here are expensive,
the whole process becomes
more expensive than any
other types.

18.  The look of the house get spoilt
with spray foam technique. So
people have to choose some
alternative ailment in hiding such
look.
 That makes the process even
more expensive.

19.  These are some of the disadvantages of
the common types of insulation
 Go this way to get more points regarding
the pitfalls

20.  Aesofutah is the insulation contractor in
Utah.
 They have efficient energy inspectors to
monitor the R-value and implement
design procedure based on calculated
value.
