What are the benefits of radiant barriers in attics?
In hot climates, benefits of attic radiant barriers include
both dollar savings and increased comfort.
Without a radiant barrier, your roof radiates
solar-generated heat to the insulation below it. The insulation absorbs the
heat and gradually transfers it to the material it touches, principally, the
ceiling. This heat transfer makes your air conditioner run longer and consume more
electricity.
An aluminum foil radiant barrier blocks 95 percent of the
heat radiated down by the roof so it can't reach the insulation.
In summer, when your roof gets very hot, a radiant barrier
cuts air-conditioning costs by blocking a sizable portion of the downward heat
gain into the building. In the warm spring and fall, radiant barriers may save
even more energy and cooling dollars by increasing your personal comfort.
During these milder seasons, outdoor air temperatures are comfortable much of
the time. Yet solar energy still heats up your roof, insulation, attic air, and
ceiling to temperatures that can make you uncomfortably warm. An attic radiant
barrier stops almost all of this downward heat transfer so that you can stay
comfortable without air conditioning during mild weather.
You may also find that radiant barriers can expand the use
of space in your home. For instance, uninsulated, unconditioned spaces such as
garages, porches, and workrooms can be more comfortable with radiant barriers.
Because radiant barriers keep attics cooler, the space is more usable for
storage.
Roof-radiated heat also warms ductwork or mechanical
equipment (air handler) in your attic. The proportion of the total heat gain
the ductwork represents, compared to heat gain to the interior of the house,
varies depending on the amount of attic and duct insulation you have.
How do radiant
barriers "block" heat transfer?
Aluminum foil, the operative material in attic radiant
barriers, has two physical properties of interest here. First, it reflects
thermal radiation very well. Second, it emits (gives off) very little heat. In
other words, aluminum is a good heat reflector and a bad heat radiator.
Your grandmother probably made use of these properties
through "kitchen physics." She covered the Thanksgiving turkey with a
loose "tent" of aluminum foil before she put it in the oven. The foil
reflected the oven's thermal radiation, so the meat cooked as evenly on top as
on the bottom. She removed the foil briefly to let the skin brown, but when she
took the bird from the oven, she "tented" it with foil again. Since
aluminum doesn't emit much heat, the turkey stayed hot until the rest of the
meal was ready. To understand the concept of not emitting heat, let's use an
analogy of a light bulb. When you turn on a light bulb, it emits light. If you
paint the light bulb black, when it is turned on, there is no light emission. A
radiant barrier has a similar effect on infrared heat. Your roof surface heats
up in the sun and will emit infrared heat. When this infrared heat heats the
radiant barrier it will not emit, or reradiate, the heat into your attic.
Cooking a turkey and painting light bulbs are simple
analogies, but the same principles of physics apply to an attic radiant
barriers. Aluminum foil across the attic airspace reflects heat radiated by the
roof. Even if the radiant barrier material has only one aluminum foil side and
that side faces down, it still stops downward heat transfer because the foil's
low emissivity will not allow it to radiate the roof's heat to the insulation
below it.

What is Reflective Bubble Insulation?
Aerolam Insulations Reflective Insulation Provides Multiple
Benefits
Aerolam Insulations products consist of single or double
layers of Barrier Bubble material laminated between layers of metalized film to
provide excellent thermal resistance. The bubble contains an air retention
layer designed to provide increased strength and puncture resistance.
Insulation is used to either contain heat for maintaining
warmth, or to resist heat for maintaining cold. In many applications, radiation
is the dominant mode of heat transfer. Aerolam foil bubble is considerably more
effective than conventional insulations in reducing radiant heat transfer.
Foil bubble reflects up to 95% of radiant energy in addition
to resisting other types of heat transfer thus providing effective insulation.
High-Efficiency
Performance
Thin, lightweight material provides resistance against the
three types of heat flow: conduction, convection and radiation. It forms an
effective barrier against moisture, air currents and vapors, while resisting
fungus, insects and nesting rodents.
Easy to Use
It’s lightweight, compact and pliable yet resistant to
punctures, tears and cracking. Conforms easily to fit complex shapes.
Installation is quick and simple.
Cost-Effective and
Versatile
An economical solution for a wide range of industrial,
manufacturing and consumer applications.

Reflective Insulation and Radiant Barriers
Reflective insulation, is normally made of aluminum foil,
it's also known as a radiant barrier and is very Flexible, Light-Weight and
easy to Fit.
Everyone has seen reflective insulation without realising
it. Paramedics use it as emergency blankets. Firefighters protect themselves
from fires with reflective foil insulation. Companies such as NASA use
reflective insulation on their shuttles, they protect astronauts with it
aswell.
Reflective insulation, mainly blocks radiant heat from
transferring through air gaps. Radiant barriers reflect and block excessive
heat in the summer and retain heat through winter. Reflective insulation will
also reflect the heat generated in your home back inside and block the heat
from escaping. Meaning there is less heat escaping keeping your home warmer
from less heating for longer. Resulting in lower fuel bills.
Radiant barriers are like all other types of insulation because
they lower the amount of heat that enters or exits a home. Other types of
insulation trap air inside the insulation, not allowing it to escape and
consuming a lot of space. Reflective insulation works to decrease the flow of
heat through an airspace using minimal space.
Reflective insulation does not absorb moisture. When used in
conjunction with other insulation, it tends to keep the insulation drier and
has a better overall performance. It can be used in homes, transportation,
factories, greenhouses, summerhouses, barns, conservatories and Many More!
Benefits of
Reflective Insulation
·
Light weight, very strong and easy to install
·
Moisture-proof - will not allow moisture to pass
through in either direction
·
Eliminates condensation within the ceiling and
walls when properly installed as a vapor barrier
·
Unaffected by humidity with lower moisture
transfer and absorption rates than mass insulation - no mildew, mold or fungus
growth
·
No significant mass to absorb and retain heat
·
No change thermal performance over time due to
compaction, disintegration or moisture absorption - common concerns with mass
insulation

Insulation - A Long-Term Power Saving Investment
Insulation, by definition, refers to a mechanism to shield
an interior, by using material that prevents either heat loss or gain, or sound
transmission. There are varied forms of insulation, such as fire insulation,
electrical insulation or impact insulation, however, we would primarily be
focusing on thermal insulation, since it plays a major role in raising our
quality of lives, and helping us save on power-bills.
Modern day buildings and high-rises are a form of a
miniature ecosystem unto themselves. Ideal temperature and humidity levels are
maintained to keep the occupants comfortable, irrespective of what the weather
outside is. Cities, with their traffic and other distractions can be pretty
noisy too, and the interior of our buildings is also somewhat shielded from
that noise. Insulation, is thus used to reduce unwanted heat loss or gain, and
can decrease the energy demands of air-conditioning systems. Certain effective
insulation materials in use are glass wool, cellulose, rock wool, polystyrene,
per-liter, wood fiber, plant fiber, urethane foam, vermiculite etc.
Factors like a building's design, local climatic conditions,
prevailing power tariffs, and the client's budget and requirements are taken
into consideration before deciding upon what type of insulation to employ.
Building codes pertaining to that region also play a role in the choice or type
of building insulation used. Professionals like a qualified home energy auditor
are consulted to analyze energy requirements, and decide upon the best insulation
procedure. First and foremost, the 'thermal envelope' for the building has to
be defined. A thermal envelope is the area in the building that needs to be
insulated, wherein areas like the attic, and the basement are usually not
included. The smaller the area to condition, the lesser the insulation costs
and energy bills. It is imperative that proper planning for the layout of the
insulation is done before the building work commences, since the retro -
fitment of insulation requires parts of the building to be deconstructed to
reach the inner layers for placement of the insulation material, which could be
a major inconvenience to the occupants.
Often, as part of the insulation procedure, 'radiant
barriers' are placed to reduce radiant heat transfer across an air space.
Radiator insulation works in an effective manner by reflecting the heat,
thereby not allowing it to get absorbed by the building. The downward heat flow
is, thereby, also reduced, since the upward heat flow tends to be dominated by
convection. The major component of building insulation is, however, the bulk
insulators which block conductive heat transfer and convective flow, either
into the building, or out of it.The bulk insulators are capable of resisting
conductive heat transfer using the air spaces found in material like foam,
fibers or plastic bubbles. Bulk insulators are particularly effective for
air-conditioned buildings.
