Perlite 100L

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.

What is Perlite?

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

What can it be used for?

Perlite is widely used in commercial hydroponics, seed starting and plant rooting, as a soil conditioner, and to enhance the water-holding and anti-compaction properties of growing soils.

What grades are available?

Perlite can be supplied in a number of grades, depending on the particular requirements of the application.

SwiftAir Perlite is 2-5mm



Non-combustible ultra-lightweight mineral aggregate with excellent insulation & adsorption properties.


SwiftAir exfoliated vermiculite and expanded perlite are absorbents and carriers. Each of these unique minerals have their own characteristics.


Perlite insulation is used in high temperature applications in the steel and foundry industries such as ladle topping, hot topping and risering.

Cavity Fill

SwiftAir coated expanded perlite is a hydrophobic insulating aggregate. This water repellent, non-flammable, loose-pour insulant improves the thermal performance on masonry walls and floors.


Due to its high insulating qualities and versatility expanded perlite is widely used in the construction industry for masonry and other build types.

Vermiculite - Standard 100L

Another firm favourite with keen gardeners is vermiculite and when you want to retain water than choose to add vermiculite to your chosen media.


Vermiculite is a natural sterile soft mica mineral with great water holding and insulation properties. It also offers a high cation exchange capacity which means it will slowly release nutrients back to your plant which it has absorbed during watering.


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.


Vermiculite is easy and safe to handle and odourless whilst also being lightweight and simple to use.


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.

Our vermiculite grade is Medium, which is a nominal size range 2.0-5.0mm

Volcanic LAVA 5-10mm
Lava granulation 5-10mm

This volcanic rock is a great biological filter media and Media mix, it will provide a home to friendly filter bacteria when used for fish tanks. Like with the ceramics, the porous structure of the lava is a perfect material for deposition of nitrifying bacteria.
After growing on the lava rock surface, this bacteria will clean the water from ammonia and nitrite to reduce toxic nitrites, which are then collected by the plants.
Lava Rock has a positive effect on the biological balance in the aquarium, it clarifies the water and stabilizes the pH.

Before inserting the filter we recommend to rinse it.
Once settled in the tank, it is important to rinse the media filer only with water that was already in the aquarium. This will help to keep the beneficial nitrifying bacteria on its surface
