1. THERMAL & SOUND INSULATION MATERIALS

2. Insulation Insulation is a general term used to describe materials that are designed to prevent transmission of electricity, heat, moisture, shock or sound from one area to another. It's normally used to keep heat and/or sound in or out of your home, or to keep it from spreading. Thermal Insulation Thermal insulation is a material or materials used in buildings to regulate indoor temperatures. It is the reduction of heat transfer between objects in thermal contact or in range of radiative influence. In simple terms, thermal insulation of buildings mean in hotter area keep the room cold and in colder area keep the hot.

3. NECESSITY The thermal insulation in building is to maintain a comfortable temperature in building. It is used as a barrier to prevent heating and cooling flow from escaping your house. The main purpose of thermal insulation in winter is energy conservation leading to decrease in heating damage. It also prevents summertime overheating of building. ADVANTAGES Thermal insulation keeps the rooms cool in summer and warm in winter, resulting in comfortable living and working condition. The use of thermal insulation material inside a room prevents the moisture deposition on interior walls, ceiling. Due to Thermal insulation, the demand of heating in winter and cooling in summer is considerably reduced, resulting in lot of fuel saving and maintenance cost.

4. FIBERGLASS TYPES OF THERMAL INSULATIONS

5. Fibre glass insulating material is made up of extremely fine glass fibres . It is made from molten glass that is spun or blown into fibres. Most manufacturers use up to 40% to 60% recycled glass content. These fibre glass insulating material come in 2 types. One is in roll or batts and other one is rigid boards. It is the most common insulation used in modern time. It is able to minimize heat transfer. FIBERGLASS : Advantage: It can be easily moulded into any shape and has mechanical strength that is so strong and stiff. It lasts for long time. Minimum maintenance required. It is anti-magnetic, fire resistant, good electrical insulator and fire proof. Disadvantage: It needs to be re-gel coated every 5 years. It may not work if it is wet or damp during installation.

6. CELLULOSE

7. Cellulose insulation is one of the most eco-friendly form of insulation. It is made from recycled cardboard, paper, and other similar material comes in loose foam. The paper is first reduced to small pieces and then fiberized, creating a product that packs tightly into building cavities. Cellulose is also most fire resistance forms of insulation. It is use to reduce building heat loss and gain , noise trance mission. Advantage: Cellulose insulation is treated with boric acid which makes them fire resistant and makes them unpalatable. Have long term thermal insulating properties. Are cheaper than fiberglass. Normally health risk is less. Disadvantage: Creates enormous amount of dust when installed. Cellulose insulation absorbs moisture easily and decreases the long term insulating properties. CELLULOSE :

8. MINERAL WOOL

9. Mineral wool is one type of fibrous material drawn from molten mineral or rock mineral or manufactured from recycled glass. It is also known as glass wool. It may refer to rock wool which is a type of insulation made from basalt. Finally it may refer to slag wool which is produced from the slag from steel mills. It can be purchased in bats or as a loose material. Advantages: It is installed as sheet into walls. It is fire resistant and n oise resistant. Disadvantage: I t is a very expensive material. MINERAL WOOL :

10. POLYSTYRENE

11. Polystyrene also known as Styrofoam is a type of rigid  foam insulation  which is commonly used in residential and commercial settings. It is water proof thermoplastic foam which is excellent sound and temperature insulation material. It comes in 2 types: Expanded and Extruded. These two types are differing in performance and cost. Its insulation has an unequally smooth surface which no other type of insulation possesses. T he foam is usually created or cut into blocks , ideal foam wall insulation. POLYSTYRENE : Advantages: It has the ability to change and respond by the shape of the external impact force buffering . P olystyrene foam is a recyclable material. Disadvantage: Common polystyrene foam insulation board is easy to burn, toxic smoke is produced by combustion, even after adding a flame retardant. T he strength of the material is poor and prone to cracking,

12. POLYURETHANE FOAM

13. Polyurethane foam insulation is made up of two chemicals. These foam insulation are spread on walls and roofs and then it solidifies to make an insulating material. There are two types of foam material , one is open cell spray foam. And another is closed cell spray foam. Have stable insulation over time. Reduces air and moisture Infiltration resulting in a more consistent temperature. Polyurethane insulation is available as a liquid sprayed form and rigid foam board. The material contains low conductivity gas in its c ells. POLYURETHANE FOAM : Advantages: The advantage of polyurethane foam is its easy application. It adapts perfectly to oblique and difficult surfaces.  It is very light and can be used for most jobs. Disadvantage: I t is a very expensive material.

14. INSULATION PANELS TYPES OF SOUND INSULATIONS

15. Sound insulation is the ability of building elements or structures to reduce sound transmission. It is a method of reducing the amount of sound reaching a particular point such as a room. Sound Insulation

16. Panels are mainly used to insulate  existing walls , floors, and ceilings. Drywall panels offer a source of mass that is an essential proofing property. Dampened drywall incorporates a sound blocking layer for extra insulation. D ampening compound on two sheets of drywall can be applied to create a dampened one. A room  can also be soundproofed using sound boards in floors as a spacing layer. However, they don’t provide maximum insulation from sound but are useful where extra proofing mass is not required. INSULATION PANELS :

17. MASS LOADED VINYL (MLV)

18. Mass Loaded Vinyl material is dense, highly flexible with excellent sound insulation properties. It is helpful in filling gaps, wrapping metal columns and pipes or where a flexible sound barrier is required. It is a good commercial soundproof material due to the durability and quality features in sound insulation. MASS LOADED VINYL : Advantages: Thinness:  Its combination of thinness and lightness results in the superior mass to thickness ratio which gives MLV a considerable advantage over other noise reduction materials. Its lightness also means you can use it on drywall without fear of it collapsing or caving under its weight. Flexibility:  Another significant advantage of MLV is its flexibility which completely separates it from most other soundproofing materials which are rigid. You can twist, wrap and bend MLV anyway you want to install on surfaces of all shapes and forms. Disadvantage: I t is a very expensive material.

19. QUIET BATT

20. Quiet Batt is a 3 inch premium, high-performance soundproofing and thermal insulation product designed for use in both interior and exterior walls, ceilings and attic applications. It absorbs sound within exterior and interior wall, ceiling and attic cavities . Quiet batt acoustic insulation acoustically outperforms standard fiberglass, rock wool, cellulose and foam insulations. QUIET BATT : Advantages: Easy to install. H igh-quality sound absorption. I t can reduce heating and cooling bills. Low cost. L ightweight and easy to handle.
