在这第二个添加的" roi驱动产品，"we take a look at insulation, which is a big part of a building’s envelope. When insulation is installed correctly, it provides the necessary R-value to meet the thermal demands of the region and the comfort demands of the building’s occupants. With energy prices on the rise, building envelopes have come under more and more scrutiny. Homeowners and business owners alike are now seeing the need to improve the building envelope and increase its overall efficiency.

Air leaks, or what are commonly known as drafts, occur at penetrable locations along a ceiling, beneath an attic. Common locations where air has the ability to leak into an attic include gaps between sheets of drywall; holes through which wiring runs; and around an attic hatch cover, a chimney, recessed lighting, or plumbing and mechanical vents. During the colder months, as heat rises through your home, these gaps will allow warm, humid air to circulate into the unconditioned attic. Locating and sealing these leaks will prevent a rise in the ambient temperature of your attic. Energy Star has developed a helpful guide, “A Do-it-Yourself Guide to Sealing and Insulating with Energy Star,” that provides information about what materials, precautions, and methods are necessary to seal attic air leaks. foamed-in-place insulation. href="//www.diesprinter.com/www/division-07-thermal-and-moisture-protection/item/1095-sprayed-foam-and-foamed-in-place-insulation" target="_self">sprayed-foam or foamed-in-placed insulation.
Liquid foam insulation materials can be sprayed, foamed-in-place, injected, or poured. Their ability to fill even the smallest cavities gives them twice the R-value per inch than traditional batt insulation.
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 any structures or finishes. This ability to conform makes loose-fill insulation well suited for retrofits and for places where it's difficult to install some other types of insulation.
Vermiculite and perlite insulation materials are commonly found as attic insulation in homes built before 1950. Vermiculite insulation materials aren't widely used anymore because they sometimes contain asbestos. However, according to the U.S. Environmental Protection Agency, asbestos is not intrinsic to vermiculite. Only a few sources of vermiculite have been found to contain more than tiny trace amounts. Still, if you have vermiculite insulation in your attic, do not disturb it. If you want to add insulation to your attic, use an insulation contractor who is trained and certified in handling asbestos.
Insulated concrete blocks can accommodate many walls in a home. Their cores are filled with insulation (except for those cells requiring structural steel reinforcing and concrete infill), which raises the average wall R-value. The better concrete masonry units reduce the area of connecting webs as much as possible.
Some natural fibers — including cotton, sheep's wool, straw, and hemp — are used as insulation materials.
The term "mineral wool" typically refers to two types of insulation material:
Facings are fastened to insulation materials during the manufacturing process. A facing protects an insulation's surface, holds the insulation together, and facilitates fastening. Some types of facing can also act as an air barrier, radiant barrier, and/or vapor barrier. Some even provide flame resistance.
Properly insulating and air sealing your attic will help reduce your energy bills. Attics are often one of the easiest places in a house to insulate, especially if you'd like to add insulation.
When insulating your home, you can choose from many types of insulation. To choose the best type of insulation, you should first determine the following:
Your state and local building codes probably include minimum insulation requirements, but to build an energy-efficient home, you may need or want to exceed them. For maximum energy efficiency, you should also consider the interaction between the insulation and other building components. This is called the whole-house systems design approach.
You need insulation in your home to provide resistance to heat flow. The more heat flow resistance your insulation provides, the lower your heating and cooling costs.
Properly insulating your home will not only help reduce your heating and cooling costs but also make your home more comfortable. Here you'll find the following information:
This topic includes information related to thermal insulation installed during construction. Thermal insulation materials are installed in ceiling, attics, crawl spaces, exterior walls, under concrete slabs and around foundation walls, to reduce the rate of heat transfer. Thermal insulation materials are manufactured products that take the form of board, blanket, foam, loose-fill, blown or sprayed materials.
