There are different modern materials for insulation. Below is the list of modern materials and alternative materials used in insulation.
- Glass Fiber (Fiberglass): In a place like cathedral ceiling wherein there are very low cavity space, fiber glass must be used for insulation. There are companies that make combination of glasses and fuse it together for the purpose of safer and less irritating products. All loose fiberglasses have the same functions in terms in thermal insulation.
- Mineral Wool: There are three types of mineral insulation: glass wool, rock wool and slag wool. The very good thing about mineral wool is that it is fire resistant.
- Plastic Fiber: This type of insulation does not eagerly burn and it is non- irritating. Like a typical plastic it will just melt once bared to flame. The downside of it is that, when it is being exposed to flame, it melts.
- Nitrogen-based Urea-Formaldehyde (UF) Foam: This foam, which is also usually coined as Urea-Formaldehyde (UF) foam has already existed and has been in use since 1970 but because of all the related health issues it was stopped. It uses dense air for expanding.
- Phenolic Foam: This material is widely used for foam board insulation. It is effective but has disadvantage effect.
- Polyurethane Foams: The polyurethane foam uses non- CFC also known as chlorofluorocarbon gas. It is sprayed to all the cavities with open walls and automatically fills and seals the cavity. It is water and steam permeable, flexible, and is resistant to moisture and fire. It also provides high-quality air sealing.
- Cementitious Foam: This foam insulation is used in closed cavities. Avoid contact to water so that it will not be damaged.
- Concrete Block Insulations: There are varieties of shape and composition of concrete blocks. It is widely used in the United States. It is very common upon the filling of all the webs.
- Specialized Devices: Devices are used for insulating the attic ductwork by filling the loose materials.
- “Natural” Fibers: There are several natural fibers like wool, cotton, straw and hemp that are used for insulation.
- Cotton insulation is the same with fiberglass and cellulose insulation.
- Wool and hemp insulation have the same fibrous insulation types. They are used in places that are industrialized.
- Straw bale is widely used sometime ago but since there are still flaws of using it, people discontinue using this kind of materials for insulation.
Those mentioned above are some materials used for radiant barrier insulation that could diminish the heat entering into your home especially during summer time. Most of the materials does not absorb the heat but instead reflect it.
