What Is Refractory Vermiculite?

Refractory vermiculite is a naturally occurring mineral that expands when exposed to high heat, forming lightweight, fire-resistant granules.
Once expanded, vermiculite exhibits exceptional thermal insulation, fire resistance, and acoustic absorption properties — making it ideal for high-temperature and refractory applications.

It is used as a core component in insulation bricks, castables, boards, coatings, and mortars designed to handle temperatures up to 1,100°C and beyond.

At Olinc, our refractory vermiculite is processed under strict quality standards, ensuring consistency, performance, and long service life.

Types of Refractory Vermiculite Supplied by Olinc

Olinc offers various grades and particle sizes of vermiculite for different industrial and construction applications:

  • Fine Grade (0–1mm): For coatings, lightweight mortars, and fireproof boards.
  • Medium Grade (1–3mm): For casting, insulation backfill, and cementitious products.
  • Coarse Grade (3–6mm): For loose-fill insulation and refractory linings.
  • Vermiculite Boards: Pre-pressed boards for lining stoves, ovens, and furnaces.
  • Vermiculite Cement and Mortars: Blended with binders for high-strength refractory linings.

Each grade is manufactured to meet high thermal efficiency, mechanical stability, and safety requirements.

Applications of Refractory Vermiculite in Kenya

Industrial Furnaces and Kilns

Olinc’s refractory vermiculite is used to insulate industrial furnaces, boilers, incinerators, and kilns.
It provides:

  • High thermal insulation
  • Lightweight structure
  • Fire resistance
  • Prolonged refractory lining lifespan

It’s ideal for steel, cement, and ceramics industries where heat control and energy efficiency are vital.


 Pizza Ovens, Stoves & Fireplaces

Refractory vermiculite is the go-to material for wood-fired pizza ovens, fireplaces, and domestic stoves in Kenya.
Benefits include:

  • Excellent heat retention
  • Safe, non-toxic insulation
  • Lightweight and easy installation

  • Reduces heat loss and cooking time

Whether for commercial kitchens or home installations, Olinc’s vermiculite ensures even heat distribution and long-lasting performance.


Boilers and Thermal Plants

In boilers and power stations, refractory vermiculite acts as a thermal backfill or insulating barrier, reducing heat loss and protecting metal structures.
It’s perfect for use in:

  • Steam boilers
  • Heat exchangers
  • Turbine insulation systems

Its high thermal resistance lowers energy consumption and maintenance costs.


 Foundries and Metal Casting

Foundries use vermiculite for:

  • Hot topping compounds (to retain molten metal temperature)
  • Ladle insulation
  • Casting molds

This prevents rapid heat loss, enhances metal yield, and minimizes oxidation during casting.


 Construction and Building Materials

Vermiculite is widely used in the Kenyan construction sector for:

  • Lightweight, fireproof plaster and screeds
  • Acoustic insulation boards
  • Thermal insulation layers under concrete slabs
  • Roof and wall insulation

It is the preferred material in energy-efficient green building projects due to its eco-friendly nature.


 Agriculture and Horticulture (Dual Use)

Although primarily refractory, vermiculite can also improve soil texture and moisture retention when blended with soil — ideal for nurseries, hydroponics, and greenhouse farms.

Advantages of Using Olinc Refractory Vermiculite
