There are many types of cuerdas de aislamiento. A popular one consists of sheep wool insulation that has higher performance than glass fiber. Wool has the ability to absorb moisture by heating up. It also has the unique ability of absorbing VOC gases. Similarly, wood fiber is among the most popular household cuerdas de aislamiento. Wood fiber can be used as internal insulation as well as external insulation that reduces thermal bridges.


On the long list of cuerdas de aislamiento is also the cotton insulation that provides the following benefits: very low toxicity and no cancer risk from airborne fibers. Right below cotton (in safety terms) is fiberglass which is the most common residential insulating material that is applied as pressed between studs. However, green building practices shun fiberglass insulation because The World Health Organization has declared fiber glass insulation as potentially carcinogenic.


Regarding all types of cuerdas de aislamiento, the need for proper handling of insulation materials is essential to the health of all household residents. The safe handling and use of insulation materials is incorporated in education and training for the manufacture, fabrication and installation of fiber glass, rock wool and slag wool insulation products. This type of training is freely offered by the North American Insulation Manufacturers Association which should be consulted by all users for authoritative information on insulation safety.


Among household cuerdas de aislamiento are refractorios used as materials that can protect house walls as well as the residents of the house. The house itself is protected from extreme temperatures and the people are protected from toxicity produced by heat. 

Refractarios are materials that have an unusually high melting point. The most important aspects regarding refractories are: the essential properties of ceramic refractories and their applications, the processing techniques employed in the manufacture of refractories and the connection between the properties of refractories and their chemistry and microstructure. 


Ceramics are useful as refractarios due to the property of chemical inertness. In addition to temperature and corrosion resistance, refractarios must possess superior physical wear or abrasion resistance and must be resistant to the thermal shock that occurs when an object is rapidly cooled from high temperature. Moreover, most refractarios are quite porous and are presented with large amounts of air spaces that can reduce the load-bearing strength of the product but it can also reduce susceptibility to thermal shock.


The composition and processing of ceramic refractarios vary according to their applications. Most refractarios are either clay-based or non-clay based. Among clay-based refarctarios are: fireclay, high-alumina, silica and zircon materials. The category of clay-based products also includes: mortars for cementing bricks, mixes for ramming and gunning, fireboards, blankets and vacuum-cast shapes.
