How to Buy Insulation on eBay

Several benefits can come out of insulating an infrastructure. Thermal insulation helps prevent heat loss or heat gain inside a building. Furthermore, the use of heating and cooling systems can be reduced when a building is insulated properly, helping a business save money on energy cost. Any business with a physical location needs thermal insulation. Long ago, plant straws and animal fibres were the chief insulation materials for an establishment, and although fibres are still used, there are more types of insulation to find on online sites such as eBay.

Ideally, insulation should be installed during construction because it is easier to do so. However, insulation can be installed post-construction or during retrofitting. The endeavour can be quite costly and difficult since parts of the building need to be deconstructed. Either way, when planning on insulating a building remember that there are different types of insulation, and each has a different purpose or is used in different parts of a building. Knowing the nature of these types can lead to better understanding of industrial insulation, which leads to a wiser purchase decision.

Industrial Insulation

The word insulation can refer to a variety of objects, but the majority of types of insulation in buildings are for thermal purposes. The capability of the insulation material itself is rated by its R-value. The R-value is for the material only, however, and it does not evaluate other factors, such as local environmental factors and quality of construction.

Insulation is useful in both cold and hot climates. The main goal of thermal insulation in cold climates is to lessen heat leakage in the building. Doors, windows, roofs, walls, and air infiltration barriers are points where heat can flow out of the building, and it is important that they are properly insulated. In hot conditions, solar radiation is the source of heat gain inside a building, and too much of it creates discomfort amongst the employees. Another negative effect is overheating of machines inside the building. Insulating for hot seasons lessen the use of cooling systems.

Different Types of Industrial Insulation

As mentioned there is a variety of industrial insulation used in a building. The different types of insulation include loose-fill insulation, blanket insulation, blanket insulation, foam board or rigid board insulation, spray foam insulation, aluminium foil bubble insulation, and pipe insulation.

Loose-Fill Insulation

This type of insulation is made of loose fibres and fibre pellets that are applied using special equipment. Loose-fill insulation is a very effective type of insulation, but it is very expensive. One material used in loose-fill insulation is cellulose fibre, made from recycled newspaper and a great additional insulation to fortify a finished area.

Another is fibreglass. Fibreglass insulation is for open new wall cavities and can be blown in using special equipment, or it can also be poured in. Such loose-fill insulation is a great fit for irregularly-shaped areas and around obstructions. Mineral loose-fill insulation, on the other hand, is made of rock wool or slag wool, and they are applicable to hard-to-reach areas, including floors nearing the roof.

Blanket Insulation

Blanket insulation can be composed of either processed fibreglass or rock wool, which is mineral fibres. Careful installation is needed when using blanket insulation. This cheapest type of insulation is fitted between rafters and wood frames to insulate ceilings, walls, and floors. Blanket insulation is also called blanket roll.

Foam Board or Rigid Board Insulation

Polystyrene, polyurethane, or polyisocyanurate can make up a foam or rigid board insulation. Polystyrene is great for unfinished walls, and even the thin variants have high insulating value. Polyisocyanurate, just like the first material, is also great for unfinished walls, including foundation walls. Both polystyrene and polyisocyanurate must be installed with 1/2-inch gypsum board or other materials that have a building code approval.

On the other hand, polyurethane is used in ceilings and floors, and when installed continuously over joists or frames, it can block thermal short circuits. Polyurethane foam should not be installed in areas prone to mechanical wear and tear. When installing this type of insulation on the exterior of the building, the insulation must be covered with waterproof facing.

Spray Foam Insulation

Spray foam insulation is a combination of a foaming agent and a polymer agent. Such type of installation is best for retrofitting because it can re-insulate areas. Spray foam insulation is effective in sealing cracks and small spaces. It also insulates irregularly shaped areas.

Spray foam insulation can be made of cementitious, phenolic, and polyisocyanurate materials. Usually applied in enclosed walls, these materials are effective insulation reinforcements for existing finished areas, around obstructions, and irregularly-shaped areas. It is sprayed as a liquid, but it quickly solidifies into a plastic form that is filled with small air-packed cells. Although spray foam insulation is more expensive than its blanket counterpart, it has the advantage of automatically forming an airtight barrier when applied. Other insulation types may need additional processes to make sure that the areas where they are installed are airtight.

Aluminium Foil Bubble Insulation

Bubble insulation materials can be confused with the bubble wraps used for packaging because of their similarity, but bubble insulation is much stronger and more durable. Plus, it has the capacity of insulating parts of the building. This type of insulation is used in industrial infrastructure and other buildings to reduce the heat coming inside.

Aluminium foil bubble insulation is good in reflecting heat to keep the interior of a building cool; a double aluminium foil bubble insulation reflects more than 90 per cent of radiant heat rays. It is composed of polyethylene air bubble film sandwiched with two layers of aluminium. Buyers have the assurance that the insulation is not prone to tears and punctures for a long period of time.

Aluminium foil bubble insulation can be installed in ceilings, roofs, crawl spaces, metal structures, underground walls, concrete walls, steel walls, warm ducts, and floors. This insulation material is particularly useful in hot conditions as it blocks heat and sun rays. It is still useful in cold conditions because it prevents the heat inside the building from leaking outside.

Pipe Insulation

Pipe insulation is also important when insulating a building. Insulating pipes has the benefits of controlling condensation, preventing pipes from freezing, protecting pipes against extreme temperatures, controlling noise, and saving energy. Pipe insulation can be made of mineral wools, such as slag and rock wools that operate at high temperatures and they exhibit fire performance when tested. Glass wool is another material used as pipe insulation, and it has the same capacity as mineral wools have.

Flexible elastomeric foam is another effective pipe insulation material that prevents condensation, making it especially useful in insulating refrigerator and air-conditioning pipework. Polyethylene is also used in pipe insulation. It is a semi-flexible plastic foam that is used to lessen heat loss in heating pipes and prevent freezing of water supply pipes.

Industrial insulation is a necessary cost of a business. The main goals of insulation are to prevent heat loss or heat gain inside a building, depending on the outdoor conditions. Industrial insulation keeps the employees comfortable and the equipment and parts of the building protected from effects of temperature. Insulation lessens the need for heating and cooling systems, which helps companies to save money on energy cost.

There are different types of industrial insulation, and each has its specific usage. For instance, spray foam insulation is specifically useful in sealing cracks, small spaces, and irregularly shaped areas, and pipe insulation is used for pipes to control condensation and noise, and it prevents water inside the pipes from freezing or losing heat. The materials used in industrial insulation also vary, and each material has its own advantage and may be used in one or more types of industrial insulation. Fibreglass, mineral fibres such as slag and rock wools, polyisocyanurate, and glass wool are materials that are used in more than one type of industrial insulation. Industrial insulation is no doubt an important part of building construction and retrofitting, and installing all the necessary types of insulations provide benefits to the employees, equipment, and the business in more than ways than one.
