Specifications

Vermiculite board used as register heat shields for wood burners 
Density:500-1000KG/M3 Adjustable 
Size: 2440x1220x(20-60)mm

Heat resistant Vermiculite board for Stove fire bricks and registration plates, fireproof fireplace surrounds. Wood burning Stoves. Easy to cut , does not expand. Vermiculite is cheaper and more efficient than fire bricks.

Highly insulating refractory panels made from vermiculite containing no ceramic fibres

Vermiculite boards are easily to cut and shape to any size fire bricks with woodworking tools; as shown in picture on right. A multitude of design possibilities
High temperature resistance, low heat accumulation in lining materials, good thermal shock resistance
High mechanical strength
Good insulation capacity providing better combustion in wood burning stoves and cleaner waste gas.
No ceramic fibres, non-dusting surfaces , non-irritant, odourless

Fire Resistant vermiculite board offer excellent thermal insulation properties and minimal shrinkage at high temperatures. These products find application where fire protection is needed such as in replacement Fire Bricks, panels and bespoke applications where fire resistance or low electrical conductivity is required.
The Vermiculite boards are available in a number of different sizes

Increase the efficiency of your Wood burning Stove

A good idea which increases efficiency of your Wood burning Stove is to replace the grate or cover it with a piece of vermiculite board and allow a good layer of ash to form on the base of the stove.

This reduces the primary air flow and slows down the rate at which the wood burns.

What is Vermiculite

Vermiculite 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. It is a safe inert material, 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) it 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. The expanded mineral is easily poured, is light, clean, highly absorbent and provides baffle against impact shock when used for packaging.

 

Exfoliated vermiculite is used in the friction brake linings market, high temperature insulation, loft insulation, various construction products, animal feeds, horticulture and many other industrial applications. With its layered structure and surface characteristics is utilised in products such as intumescent coatings and gaskets, the treatment of toxic waste and air-freight packaging of hazardous goods.

Vermiculite is inorganic
* No emission of toxic gasses
* No emission of smoke or odour
* Non-combustible
No known health hazards

Q:How to apply the quota of cement and vermiculite insulation layers?
Vermiculite is a kind of hydrate, which is blocky, flaky and granular. It is the product of weathering and alteration of natural mineral such as biotite. The interlayer water molecule is ignited at high temperature, and the volume is increased by 18-25 times. Rich in nitrogen, phosphorus, potassium, aluminum, iron, magnesium, silicate and other ingredients. Vermiculite has higher layer charge number, so it has higher cation exchange capacity and stronger cation exchange adsorption capacity. Characteristics: light weight, and good adsorption properties, not decay, can be used for 3-5 years (unlike the humus, coconut shell, clothing and other perishable).
Q:How many methods of expansion of vermiculite?
Expanded vermiculite is vermiculite as raw material, after drying, crushing and roasting, the volume of short fairy in a short period of time increases rapidly, expanding (6-20 times) and becoming a kind of golden granular material. With light weight, small thermal conductivity, fire protection, corrosion resistance, chemical stability, non-toxic, tasteless and so on. The bulk density of expanded vermiculite is about 80-180kg per cubic.
Q:What can vermiculite i do?
In appearance, the vermiculite is earthy yellow, flashing golden particles from time to time. The smaller ones are like golden powder, and the larger ones are as large as the grains of rice. Holding a handle is very light, because its weight is only 1/10 of the same volume of soil.
Q:What is vermiculite? Is it expensive to sell?
A substrate for soilless culture. General agricultural stores inside to buy, and do not sell, you can ask the boss to contact you, and now use is very common. Not very expensive
Q:Vermiculite, soilless cultivation, horticulture, vermiculite, the use of coarse?
There are two conventional specifications for raising vermiculite: 1-3mm (seedling raising, horticulture, vermiculite), 2-4mm (seedling raising, vermiculite), and various types of seedling vermiculite according to customer requirements. Seedling vermiculite is made of expanded vermiculite specially made.
Q:How to use pure vermiculite leaf cuttings succulent plants
Leaf inserts do not need to use pure vermiculite, as long as put on the soil on the line, and after the root, nothing spray, keep a certain humidity on it.
Q:What harm does sowing only use vermiculite to plant?
It is a relatively rare mineral, belonging to silicates, whose crystalline structure is monoclinic and looks like mica from its appearance. Vermiculite is produced by hydration of certain granite, which is usually produced simultaneously with asbestos. Because vermiculite has the ability of ion exchange, it has a great effect on the nutrition of the soil.
Q:Can plant nursery substrates be made with plant ash and perlite and vermiculite? Seek expert advice
See if it can be used, depending on the pH of the seedlings. But later add nutrients to acidic for more, add will neutralize part of the alkaline. The actual pH value can be measured with a test paper after adding nutrients. Neutral base material is suitable. If you can according to their suitability for the best seedling is that partial acid or alkali are not too easy to range between 8-5
Q:How does vermiculite make a roof insulation?
As the swelling of vermiculite water absorption is faster, it is better to transport raw materials to the laying site during construction, with mixing and paving to ensure the accuracy of the water cement ratio and the quality of the project.
Q:Will vermiculite be absorbed by plants?
After a considerable period of time is covered with plant root basin, put up with vermiculite, watering out of pots, every day very little without being noticed. After a considerable period of time will become less.
