Building insulation

Anousha Saleem

To make the use of any object or material to provide insulation within the building of any purpose is generally refers to building insulation.

Majority of insulation in buildings is for thermal purposes, the term also applies to acoustic insulation, fire insulation, and impact insulation (e.g. for vibrations caused by industrial applications).

To achieve thermal comforts in a building i.e the satisfaction of mind with the provided thermal environment , thermal insulation works as an important factor .

Many forms of thermal insulation also reduce noise and vibration, both coming from the outside and from other rooms inside a building, thus producing a more comfortable environment.

Building insulation

When we use insulation in a building :- The building is energy-efficient, thus saving the owner

money. It provides more uniform temperatures throughout the

space. There is less temperature gradient both vertically (between ankle height and head height) and horizontally from exterior walls, ceilings and windows to the interior walls, thus producing a more comfortable occupant environment when outside temperatures are extremely cold or hot.

It has minimal recurring expense. Unlike heating and cooling equipment, insulation is permanent and does not require maintenance, upkeep, or adjustment.

It lowers the carbon footprint of a building.

Advantages :-

Interior walls, ceilings and floors where sound control is desired.

Exterior walls. Sections sometimes overlooked are walls between living spaces and unheated garages or storage rooms, dormer walls, and the portions of walls above ceilings.

Basement walls. Floors over unheated or open spaces such as over

garages or porches. Floors over unheated basements. The cantilevered portions of floors.

Insulation—when installed into a home , commercial, institutional or industrial building— provides an environment where you can live and work comfort.

Where we can apply insulation:-

Insulation is one of the most important, cost-effective, energy saving building materials in a home. In fact, without the insulation, some of the other energy-efficient components in a home won’t perform as intended. Insulation is used as a thermal and acoustical solution in the walls, ceilings, floors, and attics of a home or every part of the building envelope. Insulation keeps your home cooler in the summer and warmer in the winter. Insulation in a home saves energy and is perhaps the most cost-effective way to lower energy bills.

Residential

Insulation systems are used extensively in commercial,

institutional and metal buildings as a solution to reduce the rate of heat transfer through the roofs and sidewalls . Board, blanket and batt insulation also installed on and within the interior walls, reduces the transmission of room-to-room noise. Insulation is used on chilled water piping, HVAC duct sand equipment for thermal, sound, condensation and process control. Insulating saves energy and helps reduce greenhouse gas Emissions.

COMMERCIAL

Insulation is used to insulate HVAC ducts and equipment, process piping, industrial equipment, tanks and vessels found in power plants, petrochemical plants, refineries and other industrial applications. These insulation systems are carefully specified to reduce energy costs, enhance process performance, reduce greenhouse gas emissions, protect personnel, control condensation, reduce noise levels and to maximize a return on investment.

Industrial

Materials that are used in a building specifically for the reduction of heat transfer in the building or otherwise which form the thermal envelop are building insulation materials.

The choice of which material or combination of materials is used depends on a wide variety of factors. Some insulation materials have health risks, some so significant the materials are no longer allowed to be used but remain in use in some older buildings such as asbestos fibers and urea.

Some of the materials are  form (batts, blankets, loose-fill, spray foam, and panels), structural contribution (insulating concrete forms, structured panels, and straw bales), functional mode (conductive, radiative, convective), resistance to heat transfer, environmental impacts, and more
