Rigid Insulation: Its Advantages and Disadvantages
Rigid insulation is installed to supplement existing insulation in walls and
ceilings of a home. This popular type of insulation is mostly used in
combination with other home insulation materials to provide adequate comfort
levels in a home's living spaces and can eventually bring down the cost of
utility bills. Rigid insulation is often used on exteriors to serve as a barrier
against cold winds, and stops the conduction of heat into the house. Rigid
insulation is waterproof, made from various materials and is available in a
different sizes and thickness.
Composition
Most rigid insulation materials are made from urethane (also known as
polyurethane), Styrofoam or polystyrene. Even though these chemicals may be
different, they have similar properties and are all equally good for insulation
use. For residential projects, the use of rigid insulation in combination with
other insulation materials is usually advised by insulation contractors. This is
because it usually results in a more durable, cost-effective and efficient
insulation system.
Advantages
Since rigid insulation materials are made from polymers or molecules of chemical
insulation materials that have been heated together, these molecules are able to
cover lots of closed air spaces within them, ensuring a superior quality
insulation. In addition, the material has both water resistant and thermal
insulation properties. Some types of rigid insulation material like Styrofoam,
which is greater in strength, is used underneath concrete floors or used
underground. It is also important to note that this kind of insulation is best
used with other materials.
Disadvantages
While rigid foam insulation certainly has its advantages, it has its share of
disadvantages, one of which is insect infestation. The material is prone to
attacks by termites and carpenter ants, which are often found destroying the
rigid foam in order to get to the wooden surface below. According to pest
control contractors, deep-boring termites that attack the insulation can be
difficult to deal with. Aside from that, rigid foam insulation can be more
expensive than fiberglass or cellulose insulation. |
