Ceramic Fiber Being used on Oven

Are you building a pizza oven or a baking oven or other ovens for domestic applications in Nairobi or other parts of Kenya? Are you wondering what kind of materials will be used for thermal insulation? If so then this is your article.

Most foods cooked using ovens require high temperatures that go beyond the normal cooking. For instance, a pizza oven requires 500oC while a cake oven will temperatures of 350oC.  To achieve these temperatures thermal insulation materials are required to prevent the heat from escaping keeping the oven superheated. The other reason for insulating ovens is to protect the users from injuries that may result on touching the hot parts of the oven.

Types of Oven Insulating Materials in Kenya

In Kenya there are three main types thermal insulating materials that are used for ovens. These are fiberglass, ceramic fiber blankets and rock wool (mineral wool).

Fiberglass insulation has thermal resistance of 538oC making it suitable to use in variety of ovens that do not require very high temperatures. Due to its lightweight, fiberglass insulation is good when used on lightweight ovens like metallic ovens.

It is relatively cheaper for somebody constructing several ovens since the average price is Ksh. 800 per square metre.

The common thickness of fiberglass available in Kenya is 50mm which is suitable though double layers can be applied for better efficiency. However, most fiberglass suppliers in Kenya sell it in rolls of 18M2, making it cost effective for several ovens.

Rockwool is quite dense and has thermal resistance of 650oC, making it quite applicable in a quite range of ovens.

Rockwool is suitable for concrete ovens where it is installed permanently. Both domestic and largescale ovens such as hotels can use rockwool as their base material as it can withstand constant use.

Rockwool is quite costly as the prices range from ksh. 4000 per square metre. Thickness of 50mm and above are suitable for use in ovens. Most rockwool suppliers in Kenya sell rolls of 5m length and 1.5m width.


Ceramic fiber blanket has a thermal resistance of 1260oC, making it a choice material for domestic and industrial ovens.

It is also lightweight and can withstand long hours of use thus suitable in ovens that often in constant use such as large hotels and bakeries. It also suitable for domestic applications due to long life.

Ceramic fiber blankets are quite high from Ksh. 6500 per square metre. It usually comes in rolls of 3.62metres in length and width of 0.6m. Thickness of 50mm is appropriate.
