What is vermiQlite insulation?
VermiQlite is the geological name given to a group of hydrated laminar minerals which are aluminium-iron-magnesium silicates, resembling mica in appearance. Rock and other impurities are removed from the crude ore which is then crushed and sorted into sizes. VermiQlite is a safe inert material and is light in colour. When heated it expands (exfoliates) up to 30 times its original volume. The exfoliation process converts the dense flakes of ore into lightweight porous granules containing innumerable minute air layers. Exfoliated (expanded) vermiQlite is light and clean to handle, has a high insulation value, acoustic-insulating properties and will absorb and hold a wide range of liquids. These granules are non-combustible, and are insoluble in water and all organic solvents. Expanded vermiQlite is easily poured, is light, clean, highly absorbent and provides baffle against impact shock when used for packaging. Exfoliated vermiQlite is used in the friction brake linings market, high temperature insulation, loft insulation, various construction products, animal feeds, horticulture and many other industrial applications. VermiQlite with its layered structure and surface characteristics, is utilized in products such as intumescing coatings and gaskets, the treatment of toxic waste and air-freight packaging of hazardous goods
VermiQlite is a naturally occurring mineral that has the unusual property of expanding into worm-like accordion shaped pieces when heated. The expanded vermiQlite is a light-weight, fire resistant, absorbent, and odorless material. These properties allow vermiQlite to be used to make numerous application , including attic insulation.
Do I have vermiQlite insulation? VermiQlite can be purchased in various forms for various uses. Sizes of vermiQlite products range from very fine particles to large (coarse) pieces nearly an inch long. VermiQlite attic insulation is a pebble-like, pour-in product and is usually light brown or gold in color.
Screeding Roof and floor as insulating concretes: exfoliated vermiQlite (typically the finer grades) can be added at site to OPC cement and other aggregates, admixtures and water to produce roof and floor concrete screeds or lightweight concrete which have the benefit of being lightweight and insulating. In many cases vermiQlite based roof screeds are often used in conjunction with other insulation materials such as XPS, PU board to form a total roofing system. A bituminous binder can also be used with exfoliated vermiQlite can to produce a dry, lightweight roof screed which has the advantages of low thermal conductivity, low moisture content and ease of placement by pouring from the bag and then tamping.
Soilfree growing media: exfoliated vermiQlite is combined with other materials such as COCO peat compost to produce soilfree growing media for the professional horticulturalist and for the home gardener. These mixes promote faster root growth and gives quick anchorage to young roots. The mixture helps retain air, plant food and moisture, releasing them as the plant requires them.


exfoliated vermiQlite is studied over , it is used as a filler material because of its low bulk density, high refractoriness, low thermal conductivity and adequate chemical inertness. All along vermiQlite has high amount of silica content. Thus effective utilization of silica based materials as a building material. Presently, vermiQlite is used for its light weight in the construction industry as a filler material above the deck slab. Experimentally some of cases are studied by using vermiQlite in some of the applications in the construction industry. Case 1: One of the famous for tradition was originated in India at conventional tile which is especially designed. Following some same methodology of the traditional tiles designed some of the mix proportions by increasing the usefulness of the tile. The tile which accepts the heat resisting parameters we designed the tile fulfilling the heat insulation property, flooring tile, roofing tile and as well as in weathering course tile replacing conventional weathering coarse tiles. Various mixes were prepared using different percentage of vermiQlite and water cement ratio. The developed vermiQlite cement tiles exhibited low water absorption, better strength properties compared with the tradition famous conventional tiles used for flooring tile purpose. Thus it involve a continuous study and it combined by introducing the material which is suited for construction industry with vermiQlite. VermiQlite insulated tile which is light in weight which is easy to handle. Designed some vermiQlite mortar with various mix design ratios. Second case if it is implemented in concrete the strength parameters and some of the physical properties of the vermiQlite insulated products. The special characteristics and usage of this material would decrease the structural weight can be decreased. Considering some other characteristics it is quite good material if it is replaced partial form gives better results.

1. INTRODUCTION
Heat in building through roof is the major cause of unconditioned building or the major load for the air conditioned building.
So we carried out the specific studies by comparing the two design methodologies in the same format in assigning the factors that
would accept all the properties and statement. The designed mix and their following characteristics at different mix proportions
are studied. VermiQlite is a inert material so to resist the heat penetration.




VermiQlite:

The name vermiQlite is derived from a combination of the Latin word vermiQlite are meaning "to breed worms," and the English suffix, meaning mineral or rock. In its expanded form, vermiQlite has a very low density and thermal conductivity, which makes it attractive for use as a soil amendment, lightweight construction aggregate, and thermal insulation filler.
VermiQlite is the geological name given to a group of hydrated laminar minerals which are aluminium-iron-magnesium silicates, resembling mica in appearance
