Building Insulation

Building insulation is actually a thermal insulation process used while construction of retrofit buildings and other commercial structures. The material used for building insulation is for reducing the temperature transfer that occurs through conduction, radiation and convention.

Insulation materials can be categorized in various components like it's composition, it's form; structural or non structural and by it's functions like conductive, convection or radiation. Non structural insulation material includes bats, blankets, cotton fills, polyurethane spray foam and vacant panels. While structural forms includes insulated concrete materials, structured non-thermal panels, straw bales and other materials like fiberglass sheets. The another method to achieve best building insulation is through using reflective radiant barrier material that avoids heat transfer and reflects most of the thermal heat back to the atmosphere.

WHY BUILDING INSULATION?

Building insulation is one of the best ways to improve the energy efficiency and reduce the cost for energy for domestic and industrial infrastructure. Insulation of the buildings helps prevent the inner warm air to be leakage to the outer cool atmosphere in winter and opposite in the summer. Building insulation gives more comfortable condition to live for in all seasons. Insulating building helps to save around 45% or energy that consume in heating and cooling.

HOW BUILDING INSULATION WORKS?

Building insulation material is made from the two different materials of polyethylene bubbled film and pure aluminum thin sheet. Both of these materials have their special characteristics for acting as thermal insulation. Air bubble of the polyethylene film reacts slowly against the temperature change due to the closed air in all bubbles and it also passes the temperature slowly to the other side compare to the other material. Thus it prevents most of the temperate and radiant heat passes through it. Particularly double bubble polyethylene film is better than the single bubble polyethylene film. The selection of these films is done on the base of requirement and temperature conditions. On the other side aluminum foil works as a reflective material that reflects most of the radiant sun rays direct back to the atmosphere and thus prevent it entering inside. Together polyethylene bubble film and aluminum foil creates a sandwiched structure that avoids almost 97% or radiant heat entering inside.

BENEFITS OF BUILDING INSULATION
  • Comfortable living atmosphere all round the year.
  • Insulating building reduces cost of heating and cooling by 45%
  • Higher ROI with small pay round period.
  • Less need of heating and cooling instruments; can be done with less capacity of instruments when compared with no insulation conditions.
  • Non toxic, non carcinogenic and odorless material.
  • Environment friendly and saves large amount of non-renewable resources.
  • Less emission of greenhouse gases.
  • Building insulation prevents moisture and vapor transmission and thus creates homogeneous indoor atmosphere throughout the year.
  • Light weight, easy to install and durable material.
  • Building insulation material comes with do it yourself installation process.
  • Also gives good amount of sound proofing.
  • Polyethylene bubble films can be recycled that reduce the industrial waste.

How much building insulation a structure will need depends on building design, climate, material used for the construction, use of metals and steel, cost of energy consumption vs cost of insulation and overall budget of insulation. The building insulation planning needs to be done carefully based on the calculated considerations of all above factors.
