Due to its high insulating qualities and versatility expanded perlite is widely used in the construction industry for masonry and other build types. Vermiculite gives perfect coverage of insulation in difficult to reach places as well as an easy to manage level fill. Micafil is typically used for chimney flue linings. Expanded Perlite is suitable for a range of landscaping applications such as green roof construction, golf green renovation and construction, planters, drainage and reduction. Vermiculite Micafil is as an excellent thermal insulating material capable of withstanding temperatures in excess of 1000C. Its nominal particle size is between 2 -15mm. Vermiculite Micafil with its free flowing properties of loose-fill, make it an excellent insulation for lofts. Micafil significantly reduces the loss of heat in cold weather and keep the interior cool in hot weather. Vermiculite is a group of hydrated laminar minerals -- aluminium-iron-magnesium silicates that resembles mica in appearance. These thin, flat flakes are subjected to high temperatures (700C to 1000C), and the vermiculite flakes will expand to many times their original size due to the microscopic layers of water within them turning to steam and forcing the laminar layers apart (exfoliation). The exfoliated vermiculite becomes granules containing microscopic air layers, which makes vermiculite lightweight and gives it excellent insulation properties. Vermiculite Micafil is clean to handle, nonabrasive, sound absorbent, resistant to decay, odourless and non-irritant.

Vermiculite can be used for propagation from seed - its retention of water makes it good for sustaining the growth of seeds; potting compost for container planting - it retains moisture whilst protecting against adverse weather and aids re-wetting; and soil conditioning - its excellent water holding capabilities makes it an excellent addition to sandy soils or dried out ground. Vermiculite Fine (1.0-3.0mm)is used to improve aeration, water management, nutrient retention and exchange and has insulation properties in growing media. No, vermiculite mines and products are regularly tested in the UK and the rest of the world to ensure they do not contain asbestos. Is Micafil the same as vermiculite? Sinclair Horticultural Grade Vermiculite is porous so it helps retain water & nutrients in the soil for release to plants. Vermiculite is a natural, non-toxic mineral that is lightweight and has thermal insulation properties which makes it ideal for use as a pot topper.Credit subject to status and affordability.

The register can be accessed through www.fca.org.uk Using Vermiculite can also aid propagation when used as a top layer as it reduces evaporation and can help ensure the seed case is lost. By using Vermiculite, you can also reduce plant stress in extreme weather conditions due to its insulation properties.

This characteristic of exfoliation, the basis for commercial use of the mineral, is the result of the mechanical separation of the layers by the rapid conversion of contained water to steam.

Vermiculite Medium Grade (3-5mm)

Expanded perlite is a white, ultra-lightweight aggregate ranging from a very fine powder to an aggregate with a particle size up to 5mm in size. It is inorganic, inert, neutral in pH, biologically stable and has no asbestos content. It has excellent thermal insulation properties over an extremely wide temperature range from cryogenics at minus 273°C (absolute zero) up to refractory applications at over 1000°C. It also has a highly adsorbent surface and a very low bulk density, which makes it an ideal carrier or low cost filler for many compound formulations. Non-combustible ultra-lightweight mineral aggregate with excellent insulation & adsorption properties. Another firm favourite with keen gardeners is vermiculite and when you want to retain water than choose to add vermiculite to your chosen media. Completely fireproof, non-irritant and fibre-free, very lightweight Micafil is used in so many ways. Free flowing and easy to install, it is ideal for thermal and acoustic insulation in lofts, between floors, interior cavity walls and for pipe protection. 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-free
