One chemical processing plant, W.R. Grace, knew about the vermiculite toxicity but reinforced their products and put their factory workers at risk for dangerous exposure to the mineral anyway. If asbestos content is present, the materials will need removal in line with the requirements for asbestos remediation. Depending on the fibre types contained within the vermiculite, the materials, friability and location will define the removal method. You should never attempt to remove it yourself, so calling in a professional company to help you is essential. Final Thoughts?

Vermiculite is a naturally occurring mineral - primarily a combination of silicon, magnesium and aluminium, it is easy to handle, sound absorbent, resistant to decay, fire-resistant and fibre-freeIn case you do not know already, then Vermiculite Micafil is a great loose-fill thermal insulating material that is designed to reduce the loss of heat in cold weather. It also enables you to keep the interior cool in warmer weather. Vermiculite is actually a naturally occurring mineral; it is simple to handle, absorbs sound, resists decay, is fire-resistant, odourless, fibre-free and non-irritant. How Much Is Needed For a Project? In 1959 Siscoe, principally interested in gold mining, sold its two wholly-owned vermiculite interests to a building supplier, Sidney Roofing & Paper Company Ltd.

As spray foam insulation is also safe and contains no toxic ingredients, it is ideal for use in family homes. Mesothelioma incidence in America is also known to be high in commercial gardeners and other occupations which deal with large amounts of loose vermiculite. Note the appearance of the vermiculite. There was a large vermiculite mine in Libby, Montana that at one point, made up for approximately 80% of the world’s vermiculite supply. What most didn’t know, however, was that all impure vermiculite from this mine held asbestos crystals. In fact, miners harvested impure vermiculite since 1881.Some vermiculite insulation may contain amphibole asbestos fibres. These products can cause health risks if disturbed during maintenance, ASBESTOS TEST REPORT, VERMICULITE, ZONOLITE [PDF] 2020/01/23 (TEM Qualitative Filtration) Lab report summary. Since a huge amount of heat is lost through your roof, one of the best ways to save energy in your homeis to insulate this area with a safe and efficient alternative material. The Benefits Of Spray Foam Insulation

Spray foam is an established product used in the UK for over 30 years and internationally for even longer with few problems.One of the main benefits of vermiculite is its ease of installation. Compared to other insulation which must be measured, nailed, or sprayed into place, vermiculite is poured into your walls, loft, or gaps, offering a strong level of thermal insulation. This can make it handy for DIY installers. It also works great as a top-up to existing insulation. If mineral wool insulation is already installed within a loft, then vermiculite insulation such as Micafilcan be poured over the top of it, helping to bolster thermal insulation and also to plug any gaps around your insulation. It can also be used to insulate difficult to reach gaps or smaller sections of a property, that other types of insulation may be unable to cover.
