Expanded Vermiculite in Kenya
Premium Expanded Vermiculite Supplier in Kenya. Kingsman Engineering & Industrial Insulations Ltd is a leading supplier of Expanded Vermiculite in Kenya, providing high-quality, lightweight, and fire-resistant insulation materials for construction, agriculture, refractory, and industrial applications. Our expanded vermiculite is manufactured from natural mineral mica that expands (or “exfoliates”) when heated at high temperatures. The result is a lightweight, inert material with excellent thermal insulation, fire resistance, and moisture retention properties — making it ideal for both industrial and commercial uses in Kenya and across East Africa.
What is Expanded Vermiculite?
Expanded vermiculite is a naturally occurring mineral that, when exposed to high heat, expands into accordion-like granules. This process enhances its insulating, absorbent, and non-combustible characteristics.
It is a non-toxic, odorless, and chemically stable material widely used in various industries — from construction and refractory to horticulture and fireproofing.

Common Questions About Vermiculite
What is vermiculite used for?
Vermiculite is used for thermal insulation, soundproofing, and soil improvement. In Kenya, it’s commonly applied in construction mixes, fireproofing walls, refractory linings, and agriculture for soil conditioning and seed germination.
Which vermiculite is best?
The best vermiculite depends on your application:
- For construction and insulation, choose Expanded Vermiculite (medium to coarse grade).
- For refractory applications, select high-temperature vermiculite with coarse granules.
- For agriculture, use fine or medium-grade agricultural vermiculite for improved soil aeration.
Kingsman Engineering supplies all grades of vermiculite to meet different industry needs.
How is vermiculite used in construction?
In construction, vermiculite is mixed with cement or gypsum to form lightweight concrete, fireproof plaster, or insulating screeds.
It helps reduce the overall weight of the structure, enhances fire resistance, and provides thermal and sound insulation.
Can you mix vermiculite with cement?
Yes, absolutely. Vermiculite can be mixed with cement to create lightweight insulating concrete.
Typical mix ratio:
1 part cement : 6–8 parts vermiculite by volume.
This mixture is ideal for roof insulation, chimney backfill, cold storage rooms, and fireproof wall panels.
