Heating Materials & Equipment Supply in Kenya and East Africa
Finding quality refractory materials in Kenya can be frustrating. You need fire bricks that actually hold up to extreme heat, castable cement that sets properly, and boiler accessories that fit right the first time. And you need a supplier who understands what the materials are for — not just a shop that moves boxes.
Isothermal Mechanical Engineering Limited supplies high-quality heating equipment and industrial refractory materials from our base at KCB Building, Enterprise Road, in Nairobi’s Industrial Area. Because we also install and maintain boilers, furnaces, kilns, and incinerators, we know exactly which materials perform in real working conditions — and we stock the same products we trust on our own jobs.
What Heating Materials Does Isothermal Supply?
Isothermal Mechanical Engineering Limited supplies a complete range of heating equipment and refractory materials in Kenya, including:
- Boilers, furnaces, industrial ovens, and incinerators
- Fire bricks — 40% alumina and 70% alumina grades
- Maxheat K and Maxheat A castable refractory cement
- Maxset-50 fine refractory cement
- Max 50 refractory concrete
- Fondu cement
- Refractory mortar and fire cement
- Globe valves and strainers
- Rubber gaskets and metallic gaskets
Whether you are building a new furnace, relining a boiler, repairing a pizza oven, or stocking up on boiler spares, we have the materials ready.
Our Refractory Materials Explained
Fire Bricks (40% and 70% Alumina)
Fire bricks are the standard lining material for furnaces, kilns, boilers, incinerators, and wood-fired pizza ovens. The alumina content determines how much heat the brick can handle and how well it resists wear.
- 40% alumina fire bricks — ideal for general-purpose applications like boilers, incinerators, and pizza ovens where temperatures are high but not extreme
- 70% alumina fire bricks — built for severe service: industrial furnaces, kilns, and high-temperature zones where ordinary bricks would fail

Castable Refractory Cement — Maxheat K and Maxheat A
Castable cement is mixed with water and poured or troweled into place, making it perfect for lining irregular shapes, patching damaged sections, and casting burner blocks or door linings.
- Maxheat K — a high-quality castable for demanding, high-temperature applications
- Maxheat A — a versatile castable suited to general refractory work
We also stock Maxset-50 fine refractory cement for smooth finishing and joint work, and Max 50 refractory concrete for structural refractory casting.
Fondu Cement, Refractory Mortar, and Fire Cement
- Fondu cement — a calcium aluminate cement used in refractory concrete and high-heat applications where ordinary Portland cement would crumble
- Refractory mortar — the bonding material for laying fire bricks, formulated to match the thermal behavior of the bricks themselves
- Fire cement — a ready-to-use paste for sealing joints, patching small cracks, and fixing refractory components in boilers, stoves, and furnaces
Boiler Accessories — Valves, Strainers, and Gaskets
A heating system is only as reliable as its fittings. We supply:
- Globe valves for precise steam and fluid flow control
- Strainers that protect valves, pumps, and equipment from debris
- Rubber gaskets and metallic gaskets for dependable sealing on flanges, doors, and pressure joints
Where Are These Materials Used?
Our heating and refractory materials serve a wide range of applications across Kenya:
- Boiler plants — refractory lining, fire cement repairs, valves, and gaskets
- Industrial furnaces and kilns — high-alumina fire bricks and castable linings
- Incinerators — refractory lining for hospitals, labs, and institutions
- Pizza ovens and bakery ovens — fire bricks and castable cement for restaurants and hotels
- Foundries and metal workshops — furnace linings and refractory repairs
How to Choose the Right Refractory Material
Three questions guide the choice:
- How hot does it get? Match the material’s temperature rating to your operating temperature, with margin to spare.
- What shape are you lining? Flat walls suit fire bricks; curves, corners, and complex shapes suit castables.
- What wears it down? Flame contact, abrasion, chemical attack, and thermal shock each call for different material properties.
Get any of these wrong and the lining fails early. That is why buying from a supplier with real installation experience matters — we have seen what works and what does not.
Why Buy Heating Materials from Isothermal?
- Genuine, quality products — we stock the same materials we use on our own installations

Frequently Asked Questions
Where can I buy fire bricks in Nairobi?
You can buy 40% and 70% alumina fire bricks from Isothermal Mechanical Engineering Limited at KCB Building, Enterprise Road, Industrial Area, Nairobi. Call +254 722 943 097 or +254 720 686 454 to check stock and pricing.
What is the difference between Maxheat K and Maxheat A?
Both are castable refractory cements, but they are formulated for different service conditions. Maxheat K suits more demanding, high-temperature applications, while Maxheat A handles general refractory work. Tell us your application and we will recommend the right grade.
Can I use ordinary cement for a pizza oven or furnace?
No. Ordinary Portland cement breaks down under sustained high heat. Use refractory materials — fire bricks, castable cement like Maxheat K or A, Fondu cement, and refractory mortar — for any structure that faces direct flame or high temperatures.
Do you deliver outside Nairobi?
Yes. We supply heating materials and equipment to clients across Kenya. Contact us to arrange delivery to your location.
Can you install the materials you supply?
Absolutely. Our team provides refractory lining installation, refractory repairs, fire cement application, and complete heating system builds. You can buy materials only, or let us handle supply and installation together.
