Sound Absorption Materials

When insulating your home, you can choose from many types of insulation. The maximum thermal performance or R-value of insulation is very dependent on proper installation. Homeowners can install some types of insulation -- notably blankets and materials that can be poured in place. Liquid foam insulation materials can be poured, but they require professional installation. Other types require professional installation. To evaluate blanket installation, you can measure batt thickness and check for gaps between batts as well as between batts and framing.

In addition, inspect insulation for a tight fit around building components that penetrate the insulation, such as electrical boxes. To evaluate sprayed or blown-in types of insulation, measure the depth of the insulation and check for gaps in coverage. Suited for standard stud and joist spacing that is relatively free from obstructions. Relatively inexpensive. Concrete block insulation. Foam board, to be placed on outside of wall usually new construction or inside of wall existing homes :.

Insulating outside of concrete block wall places mass inside conditioned space, which can moderate indoor temperatures. Autoclaved aerated concrete and autoclaved cellular concrete masonry units have 10 times the insulating value of conventional concrete. Blanket insulation -- the most common and widely available type of insulation -- comes in the form of batts or rolls.

It consists of flexible fibers, most commonly fiberglass. You also can find batts and rolls made from mineral rock and slag wool, plastic fibers, and natural fibers, such as cotton and sheep's wool. Batts and rolls are available in widths suited to standard spacing of wall studs, attic trusses or rafters, and floor joists: 2 inch x 4 inch walls can hold R or R batts; 2 inch x 6 inch walls can use R or R products.

Continuous rolls can be hand-cut and trimmed to fit. Batts with a special flame-resistant facing are available in various widths for basement walls and other places where the insulation will be left exposed. A facing also helps facilitate fastening during installation. See the table below for an overview of standard and high-performance medium-density and high-density fiberglass blankets and batts characteristics. This table is for comparison of fiberglass batts only. Concrete blocks are used to build home foundations and walls, and there are several ways to insulate them.

Field studies and computer simulations have shown, however, that core filling of any type offers little fuel savings, because heat is readily conducted through the solid parts of the walls such as block webs and mortar joints. It is more effective to install insulation over the surface of the blocks either on the exterior or interior of the foundation walls. Placing insulation on the exterior has the added advantage of containing the thermal mass of the blocks within the conditioned space, which can moderate indoor temperatures.

Some manufacturers incorporate polystyrene beads into concrete blocks, while others make concrete blocks that accommodate rigid foam inserts. In the United States, two varieties of solid, precast autoclaved concrete masonry units are now available: autoclaved aerated concrete AAC and autoclaved cellular concrete ACC. Autoclaved concrete has ten times the insulating value of conventional concrete.

The blocks are large, light, and easily sawed, nailed, and shaped with ordinary tools. The material absorbs water readily, so it requires protection from moisture. Fly ash is a waste ash produced from burning coal in electric power plants. Hollow-core units made with a mix of concrete and wood chips are also available.

They are installed by stacking the units without using mortar dry-stacking and filling the cores with concrete and structural steel. One potential problem with this type of unit is that the wood is subject to the effects of moisture and insects.

Concrete block walls are typically insulated or built with insulating concrete blocks during new home construction or major renovations. Block walls in existing homes can be insulated from the inside. Foam boards -- rigid panels of insulation -- can be used to insulate almost any part of your home, from the roof down to the foundation.

They are very effective in exterior wall sheathing, interior sheathing for basement walls, and special applications such as attic hatches. They provide good thermal resistance up to 2 times greater than most other insulating materials of the same thickness , and reduce heat conduction through structural elements, like wood and steel studs. The most common types of materials used in making foam board include polystyrene, polyisocyanurate polyiso , and polyurethane.

Insulating concrete forms ICFs are basically forms for poured concrete walls, which remain as part of the wall assembly. This system creates walls with a high thermal resistance, typically about R Even though ICF homes are constructed using concrete, they look like traditional stick-built homes. ICF systems consist of interconnected foam boards or interlocking, hollow-core foam insulation blocks.

Foam boards are fastened together using plastic ties. Along with the foam boards, steel rods rebar can be added for reinforcement before the concrete is poured. When using foam blocks, steel rods are often used inside the hollow cores to strengthen the walls. The foam webbing around the concrete-filled cores of blocks can provide easy access for insects and groundwater. To help prevent these problems, some manufacturers make insecticide-treated foam blocks and promote methods for waterproofing them.

Loose-fill insulation consists of small particles of fiber, foam, or other materials. These small particles form an insulation material that can conform to any space without disturbing structures or finishes.

This ability to conform makes loose-fill insulation well suited for retrofits and locations where it would be difficult to install other types of insulation. The most common types of materials used for loose-fill insulation include cellulose, fiberglass, and mineral rock or slag wool. All of these materials are produced using recycled waste materials.

Cellulose is primarily made from recycled newsprint. The table below compares these three materials. Some less common loose-fill insulation materials include polystyrene beads and vermiculite and perlite. Loose-fill insulation can be installed in either enclosed cavities such as walls, or unenclosed spaces such as attics. Cellulose, fiberglass, and rock wool are typically blown in by experienced installers skilled at achieving the correct density and R-values.

Polystyrene beads, vermiculite, and perlite are typically poured. The Commission issued the R-value Rule to prohibit, on an industry-wide basis, specific unfair or deceptive acts or practices. R-value ratings vary among different types and forms of home insulations and among products of the same type and form. For loose-fill insulation, each manufacturer must determine the R-value of its product at settled density and create coverage charts showing the minimum settled thickness, minimum weight per square foot, and coverage area per bag for various total R-values.

This is because as the installed thickness of loose-fill insulation increases, its settled density also increases due to compression of the insulation under its own weight. Thus, the R-value of loose-fill insulation does not change proportionately with thickness.

Unlike most common insulation systems, which resist conductive and sometimes convective heat flow, radiant barriers and reflective insulation work by reflecting radiant heat. Reflective insulation incorporates radiant barriers -- typically highly reflective aluminum foils -- into insulation systems that can include a variety of backings, such as kraft paper, plastic film, polyethylene bubbles, or cardboard, as well as thermal insulation materials. Radiant heat travels in a straight line away from any surface and heats anything solid that absorbs its energy.

When the sun heats a roof, it's primarily the sun's radiant energy that makes the roof hot. A large portion of this heat travels by conduction through the roofing materials to the attic side of the roof.

The hot roof material then radiates its gained heat energy onto the cooler attic surfaces, including the air ducts and the attic floor. A radiant barrier reduces the radiant heat transfer from the underside of the roof to the other surfaces in the attic.

To be effective, it must face an air space. Radiant barriers are more effective in hot climates, especially when cooling air ducts are located in the attic. The reduced heat gain may even allow for a smaller air conditioning system.

In cool climates, however, it's usually more cost-effective to install more thermal insulation. It is also used when there's a need for insulation that can withstand high temperatures. These products come in a range of thicknesses from 1 inch to 2.

Installation in air ducts is usually done by HVAC contractors, who fabricate the insulation at their shops or at job sites. On exterior duct surfaces, they can install the insulation by impaling it on weld pins and securing with speed clips or washers. They can also use special weld pins with integral-cupped head washers.

Unfaced boards can then be finished with reinforced insulating cement, canvas, or weatherproof mastic. Faced boards can be installed in the same way, and the joints between boards sealed with pressure-sensitive tape or glass fabric and mastic. Liquid foam insulation materials can be sprayed, foamed-in-place, injected, or poured.

Foam-in-place insulation can be blown into walls, on attic surfaces, or under floors to insulate and reduce air leakage. You can use the small pressurized cans of foam-in-place insulation to reduce air leakage in holes and cracks, such as window and door frames, and electrical and plumbing penetrations. Today, most foam materials use foaming agents that don't use chlorofluorocarbons CFCs or hydrochlorofluorocarbons HCFCs , which are harmful to the earth's ozone layer.

There are two types of foam-in-place insulation: closed-cell and open-cell. Both are typically made with polyurethane.

With closed-cell foam, the high-density cells are closed and filled with a gas that helps the foam expand to fill the spaces around it. Open-cell foam cells are not as dense and are filled with air, which gives the insulation a spongy texture.

The type of insulation you should choose depends on how you will use it and on your budget. While closed-cell foam has a greater R-value and provides stronger resistance against moisture and air leakage, the material is also much denser and is more expensive to install. Open-cell foam is lighter and less expensive but should not be used below ground level where it could absorb water.

Consult a professional insulation installer to decide what type of insulation is best for you. Some less common types include Icynene foam and Tripolymer foam.

Icynene foam can be either sprayed or injected, which makes it the most versatile.

Insu Range of Products

Insulating materials remain as important as ever. The range of available kinds is constantly increasing. Thanks to their heat-insulating properties, they help save heating and cooling energy and reduce CO2 emissions. Detail Practice: Insulating Materials offers a comprehensive catalogue of insulating materials for use in construction.

For example, when someone sings, their vocal cords vibrate and send waves through the air to the listener. Higher frequency sounds consist of short sound waves, whereas lower frequency sounds contain long waves. Lower sound waves pass through thinner materials.

Materials obtained from petrochemicals mainly polystyrene or from natural sources processed with high-energy consumptions such as glass and rock wools are commonly utilized for the insulation of buildings. From the perspective of sustainable development, it is important to choose easily recyclable, renewable, locally available and environmentally friendly raw materials. In addition, an experiment was conducted to compare the thermal performance of different materials being used at the Eco-Center in Turkey. Insulation Materials in Context of Sustainability. From construction to demolition, the reduction of energy consumption on upcoming constructions comes as a great challenge [ 1 ].

5 Methods to Insulate Your Shipping Container Home

Handbook of Ecomaterials pp Cite as. Global population growth and economic growth increase the demand for more buildings and thus more construction materials. Increases in production of construction materials lead also to greenhouse gas emission rise and depletion of natural resources. One of these materials is insulation, which increasingly plays a vital role in the energy performance of buildings and in the process reducing negative environmental impacts of the built environment. A number of studies have focused on finding substitutions for petrochemicals as a source for manufacturing building insulation. Some investigations have identified insulation materials that have lower environmental costs, for example, those that are made of natural or recycled materials. Manufacturing building insulation from agricultural by-product s is one such approach. However, these are in their early stages of development, and there is a long way to have them on the market.

It is important to know how heat is transferred in fish holds. Heat is transferred by conduction, convection or radiation, or by a combination of all three. Heat always moves from warmer to colder areas; it seeks a balance. If the interior of an insulated fish hold is colder than the outside air, the fish hold draws heat from the outside.

Thermal and Acoustic Building Insulations from Agricultural Wastes

Thermal insulation is the reduction of heat transfer i. Thermal insulation can be achieved with specially engineered methods or processes, as well as with suitable object shapes and materials. Heat flow is an inevitable consequence of contact between objects of different temperature. Thermal insulation provides a region of insulation in which thermal conduction is reduced or thermal radiation is reflected rather than absorbed by the lower-temperature body.

Thermal Insulation requirement is felt where-ever comfort conditions are desired and energy to be optimally utilized. Broadly speaking, where the insulation is used to prevent heat loss from the process the term hot insulation is used.
