Insulator Material Comparison Is One Of The Most Important Parts Of A Building

Jul 17

Insulation is one of the most important parts of a building, and choosing the right type of Insulator Material Comparison makes a significant difference in how comfortable your home or commercial space will be. The type of insulation you choose will also impact your energy costs, so it's important to know the different types of insulation available and how they differ from each other. The main factors when choosing an insulator are its R-value and its ability to resist heat flow. The higher the R-value, the more efficient the insulation.

The R-value is determined by the thickness of the insulation and its density. Fiberglass insulation is a time tested and trusted insulation that can be found in almost all home improvement stores. It is easy to install and maintains its R-value over the life of a building. It can be installed in wall cavities, attics or blown into existing walls using an air compressor. It is also available in faced or unfaced varieties.

Cellulose insulation is made of recycled newspaper and comes in loose-fill, wet-spray (used for new construction or gut rehab) and dense-pack forms. It has a high R-value but requires more batting than fiberglass. It is treated with borate for insect and fire resistance. While cellulose is very effective, it can settle after installation and can release chemical irritants. It is a good choice for retrofitting because it can be placed in wall cavities, but it is less effective at covering open attics (where it is more likely to blow into areas where wiring and ducts are located).

Mineral wool is an alternative to fiberglass. It is very durable and has an R-value between R-2.8 and R-3.5. It is non-flammable and does not contain asbestos or formaldehyde. It is often used in combination with other, more fire resistant forms of insulation because it is not a fire barrier by itself.

Other options include polyisocyanurate, an insulator that is a closed-cell plastic. It is very similar to spray foam, but has a lower R-value per inch of thickness.

For wire insulation, a popular option is polyethylene (PVC). It offers good abrasion, cut through and soldering resistance. It is also water, solvent and chemical resistant. Polyethylene can be molded or extruded, and is available in a wide range of stiffnesses. The insulation may be face or unfaced, and it is also available with fire retardants.

Some health hazardous materials such as vermiculite and urea-formaldehyde were once commonly used as insulation, but are now banned or no longer in use. Some more common health friendly choices include expanded polystyrene and polyurethane. These are made from recycled and natural materials. There are also other health-friendly alternatives such as cellulose, cotton and paper. These are becoming more popular due to their environmental benefits. However, many homeowners may find them expensive compared to other options.
