| Hot and Cold Insulation |
 |
Insulation can be considered to be a "protective" procedure in the sense that what is protect in "Process temperature"
we have established the fact that specific temperature ,within very small tolerance, are necessary element of a successful process. There are long runs of piping, large vessels, etc. that must maintain specified process temperatures to make the process work. |
|
Insulation is the means of maintaining those temperature. In a process plant insulation becomes complex becomes complex because of the amount of heat or cold it must preserve. A properly insulated process plant results in more efficient plant operation, assisting in the production of the quantity and quality of the plants products. It is, therefore, a critical requirement of plant design.

| Sound Proofing |
 |
Soundproofing is any means of reducing the intensity of sound with respect to a specified source and receptor. There are several basic approaches to reducing sound,increasing the distance between source and receiver, using noise barriers to block or absorb the energy of the sound waves, using damping structures such as sound baffles. |
|
Soundproofing affects sound in two different ways, noise reduction and noise absorption. Noise reduction simply blocks the passage of sound waves through the use of distance and intervening objects in the sound path. Noise absorption operates by transforming the sound wave. Noise absorption involves suppressing echoes, reverberation, resonance and reflection. The damping characteristics of the materials it is made out of are important in noise absorption. The wetness or moisture level in a medium can also reflect sound waves, significantly reducing and distorting the sound traveling through it, making moisture an important factor in soundproofing.

| Ducting |
 |
Heated and cooled air escapes through unsealed duct joints and holes, increasing the house's energy costs. unconditioned air can also infiltrate into ducts through unsealed points with the consequent increasing of energy bills.
If your duct system is poorly sealed and insulated, sealing and improving its insulation can reduce your heating and cooling costs. Statistics state average losses of 20-30%. |
|
When choosing ducts for you home, take into account the three main types of ducts:
Sheet Metal Ducts: It's the most common type of ducts, allowing high durability, versatility and efficiency at low costs.
Flexduct: Flex-duct involves a plastic inner liner within an insulated tube covered with a vinyl vapor barrier. Flexduct allows few duct connections and low costs.
Ductboard: Ductboard is made of high-density sheets of fiberglass with foil facing on one side. The result is a lightweight material with vapor barrier, wholly insulated, but also with some drawbacks: it is rather damageable and its durability depends strongly on tapes and mastics used on closure methods. Its cost is relatively high.

| Roof Insulation |
 |
Ceiling (and roof) insulation is critical in most buildings and climates. Even if insulation involves lifting the roof, it may be a deserving task and investment. The benefits are immense. Ceiling-roof insulation is a crucial piece of the house insulation - something that in some more extreme cases may avoid 50% of the home's heating and cooling energy losses. |
|
In cold climates, the insulation is usually restricted to ceiling (or attic).
In hot and warm climates ceiling-roof insulation involves, usually, two layers of insulation:
- Roof insulation (particularly important in hot climates)
- Ceiling insulation.
Ceilings and attics may also benefit form reflective insulation in hot climates. Insulation techniques and materials used in the various types of roofs - tile roofs, metal roofs, pitched roof with flat ceilings, sloping ceilings, cathedral ceilings, vaulted ceilings, and flat roofs - are very alike.
