Insulation is the phenomenon of reducing the flow of heat,
electricity or sound between the inner space and outer space of an
object. Insulation can be used both to prevent heat gain and from heat
loss to the surrounding areas. Most electric appliances use insulation
technology like Refrigerators, freezers and Heaters. One of the main
applications of insulation is house insulation. An insulated home is
more energy efficient, requires less maintenance and is more
comfortable, as the temperature remains uniform over weather changes.
Insulation at home helps in saving energy and reducing utility bills. It
makes the house more comfortable.
There are many types of insulation available these days like batt and
blanket insulation, loose fill insulation, Cellulosic insulation,
Reflective insulations etc. Foam insulation is one of them. Foam
insulation is performed by pouring liquid foam from a container.
Foam insulation is convenient to install while constructing the house
rather than insulating already built structures. As foam insulation is
air tight, it is not generally recommended for attic insulation that
should be properly ventilated. Also, Foam insulation is a bit more
expensive than batt and blanket insulation.
Foam installation is easy to perform with adequate instruments. They are
much more powerful and efficient than batt and blanket insulation. They
have a higher R value and provide better thermal resistance. Due to
their high efficiency, they can be installed even in small spaces. Foam
insulation is generally filled in the cavities of walls, floor, roofs
etc. Foam insulation also protects the space from moisture condensation.
Foam insulation does not shrink or settle. It is fire and
insect-resistant.
Rigid Foam Insulation is best used when space is a consideration. It is
easy to install and best when a higher R value is not needed. It is made
up of densely packed air particles and provides a high thermal
resistance. It is good for creating a barrier against energy loss and
air infiltration.
Spray-on insulation is installed with the material known as
polyurethane. Spray foam insulation is used to insulate the walls and
ceilings to keep the house warm during cold spells and to keep it cool
in summer. Spray Foam insulation is a bit more expensive than fiber
glass insulation. This type of insulation can reduce utility and repair
bills as the house is naturally warmer and free from bugs due to the
insulation. Spray foam insulation lasts longer than other types. Also,
it dos not fall off the wall like fiber glass insulation.
Proper Precautions must be taken while installing the foam insulation.
Some foam insulation materials contain chemicals that can harm the skin
and may cause lung cancer. Therefore proper masks must be put on the
face before installing them. They must not be installed near to
electrical equipments. Though, they do not catch fire easily they may
emit harmful gasses if they burn. Foam insulation should also be
protected from sunlight as ultraviolet rays from the sun may damage foam
insulation.
