What Can Be Done About Vermiculite Insulation Not Containing Asbestos?, asbestosdefinition.com | Is still used in older homes where insulation cannot be removed. It is worth noting however that if you own such a home and if you have children at home, it is really best to discuss with them how vermiculite insulation is going to affect them and the family’s health and well-being.
Despite this, should be avoided whenever possible. Many believe that vermiculite insulation not containing asbestos is far more economical and offers a greater degree of safety and control over heating costs.
This should be done for the simple reason that is often cheaper than asbestos-laden vermiculite. The solution, or it may be the problem in itself, is that vermiculite insulation not containing asbestos is often made using non-asbestos ingredients.
While it may be true that the vermiculite insulation is much cheaper than asbestos-laden vermiculite, the alternative is that vermiculite insulation not containing asbestos is no less of a health risk. In fact, vermiculite insulation not containing asbestos could be even more dangerous to health, because it is a known carcinogen.
It is not unusual to see a slab of vermiculite insulation installed on top of the walls, but without any type of support on the inside. Therefore, anyone who is in contact with the vermiculite will absorb as much as 60% of the heat that is present in the home.
There are two ways in which heat loss can be decreased through this slab. First, the user can try to insulate the wall with additional materials that would not be capable of absorbing as much heat, such as fiberglass or polystyrene; or, the home owner can install some type of air barrier that would reflect the heat back into the environment.
The second option would involve simply installing a mesh or an “air gap” that would allow some of the warm air to escape. The problem, however, is that if the air gap is opened too often, then the insulation will eventually become transparent, and heat will be able to penetrate the slab.
Vermiculite insulation not containing asbestos is not generally made to be thermally reflective. There are, however, many products made from vermiculite that have been treated in order to have some measure of thermally reflective properties.
These products include Plexiglas, Film Boards, and Sheet Films, which are referred to as a “Radiant Barrier.” Radiant barriers are not generally good enough for vermiculite insulation not containing asbestos, as these kinds of products do not provide any kind of thermal insulating properties.
Radiant barriers generally use ultraviolet radiation in order to simulate the surface of an actual slab of marble, which has much higher physical properties than the typical vermiculite insulation. The fact is that the UV radiation used in this treatment actually breaks down the vermiculite insulation, which makes the homeowner wonder why such a treatment would be necessary.
Regardless of how it is treated, the vermiculite insulation not containing asbestos will end up becoming less resistant to thermal leakage over time. Therefore, it is important that it is properly insulated, and that any venting from the insulation is controlled.
Properly insulation, controlled ventilation, and proper regulation of temperatures will make sure that heat loss is minimized. With a bit of effort, you will find that vermiculite insulation not containing asbestos will be your friend rather than your enemy, and it will be that easy for you to make it work.
