Can Oven Insulation Catch Fire? (Explained)

When food is both life and energy, anything that comes in handy or serves the purpose to cook, bake, or heat food always remains in discourse.

Percy Spencer, an engineer of the Raytheon Corporation, took only two years to release the first commercial microwave oven in 1945, after his cooking popcorn in front of a radar.

With time, they got smaller, cheaper and something necessary on a daily basis for the common people, and related materials like insulations have become equally essential. 

Earlier insulations were primarily used in attics, floors, and walls mostly to protect the home from the scorching heat or freezing cold of the outside serving as a defensive barrier between home and outside conditions.

Nevertheless, modern-day ovens require good quality insulation to provide desired services.

What is actually oven insulation? 

With a much higher heat rating than typical house insulation equipment, Oven insulation is pretty diverse, a glass wool product that helps to reduce fire risk and restricts the heat of oven sides.

Some companies develop insulations that provide higher standard thermal insulations made up of about 85% recycled glass, local raw materials like sands.

Hence, the price remains somewhat cheaper and most importantly eco-friendly. 

Regular house insulation would melt as they can’t handle the persistent heating temperature disclosure of the cooking or industrial oven. 

Earlier the main element of insulation was mostly fiberglass. As time goes by, massive shifts in cooking industries seek enhanced design flexibility,  performance, and protection. 

Insulation in the oven lets the heat surround the unit equally, throwing off the cool spots. It also protects the users’ hands or arms from getting burned by preventing the oven’s outer shell from being too hot.  

What does oven insulation do? 

In modern times almost all the families of the higher and middle class, offices, restaurants, etc everywhere microwave oven has become an indispensable machinery product.

As it is mandatory that such a tool should be operated with maximum effectiveness and total safety so that it doesn’t cause any causality, here comes the urgency of equipment like insulation. 

Do you need insulation around the oven?

Industrialists, manufacturers of ovens regularly develop excellence, performance, competitive power to stay ahead in the market where insulation is firmly under the spotlight. 

Not only to diminish danger, but thermal insulation is also crucial as up to 45% of the energy absorbed by the oven escapes as heat loss, usually across the walls.

Hence if we can lower this loss through an insulating oven, we will be able to curtail the running costs along with the oven’s environmental impact. 

Reasons why the oven needs insulation (importance)

Advanced kitchen appliances like ovens come with other necessary extra tools that improve the mentioned object’s capacity to offer the desired upshot to a consumer.   

Many years of multidisciplinary research show us that using oven insulation is important due to various reasons. Some noteworthy reasons are discussed below: 

Reduced Risk

One of the initial purposes of oven insulation is to reduce fire risk. Without insulation surrounding objects of an oven is always in danger of catching fire and if not they are sure to be damaged. 

It also safeguards the operators’ hands and bodies as it prevents the oven casing from being excessively hot which might cause severe burns to the hands or arms. 

Well cooked food

Ovens are used not only to heat numerous food and meal items but also to bake dessert, fast food etc.

Without insulation around them, there’s a high chance that food won’t be cooked properly as the oven may not be capable of achieving the desired temperature.

It helps in precluding food from remaining overcooked, burnt or half-cooked, giving the perfect taste of the desired items.  

We can say, to deliver the perfect taste and kinds of foods to food lovers, insulation for the oven is a must. 

Heat Exposure

Keeping the heat in the oven for cooking or baking is one of the main grounds why an insulating oven is pretty substantial.

It also helps to keep the adjacent area cool for living as it can’t hold the heat in itself which requires more input to let it work fine.

Otherwise, all the heat input being drained into the room might make the room toxic and inhabitable while it’s running. 

Furthermore, it is normal that the oven will warm up the room substantially and it transfers heat to the work surfaces as well. To prevent all these insulating the oven is pretty significant. 

So more insulation ensures upgraded temperature consistency of the warm working area and consequently your product.

Therefore, we can say that insulating the oven is a crucial part before one starts to use it fully. 

Energy Saver

In conjunction with providing safety measures, an insulated oven guards your wallet by reducing electricity bills through energy saving which is quite a hot issue in the manufacturing market.

No matter what you are heating or baking, kitchen appliances like ovens consume a lot of energy if not maintained wisely. 

Basically, ovens are manufactured with insulation, even then consider adding 2″ to 2.5″ of supplementary insulation to your oven walls which will make the oven cost-effective to implement along with efficiency. 

Thus, an uninsulated oven consumes extra energy while an insulated one will save thousands of dollars in terms of energy costs over the equipment life. 

To sum up, there are multiple grounds that demand that an oven has to be insulated for greater benefits. 

Can oven insulation catch fire? 

Ovens tend to catch fire for various causes. While cooking with a lot of fat and grease or alcohol, if it gets splattered, it might cause a flame.

Also, there are baking elements like butter, mayo which can start a fire by overflowing or dripping to the bottom as these are pretty flammable. 

Oven insulation helps to reduce these kinds of risks as the materials are fireproof, even though there have been a certain number of cases where using improper types of insulation started fires.

Moreover, sometimes people use conventional home insulation for ovens which is highly discouraged as they are unable to handle excessive temperatures.

On top of that, fiberglass insulation is generally fire resistant as they are made of glass combined with plastic polymers, but at a high enough temperature, it can melt.

Also, one needs to be careful with batts that are backed with foil or paper as a vapor barrier and this stuff can ignite very fast. 

So it can be said that oven insulation can catch fire if specialized high heat insulation isn’t used to safely trap the heat inside the oven. 

At what temperature does insulation burn? 

Insulations are put for safety in the first place so basically, no one installs insulation that is flammable.

At present people largely use fiberglass insulations that don’t catch fire unless there’s a high enough temperature in which case it usually melts.

Nonetheless, the brown paper that is used as a vapor barrier, foil backings, etc can easily catch on fire when the temperature is extensive.

Another ironic fact is, though fiberglass insulation won’t burn if it melts it begins to spread the heat to other flammable materials and speeds up the fire by releasing oxygen. 

Below is a table with variable data that shows the temperature range insulations can put up with

What type of insulation is used for an oven? 

Insulation in ovens is formed with multiple top notch materials to trap heat so that it doesn’t spread to places and create unwanted situations. 

Cooking equipment such as range cookers, dual cooking fuel tops, ovens etc, fiberglass is the traditional material of priority for thermal insulations which is made from silica sand mixed with limestone and soda ash. 

Although fiberglass is a somewhat outdated choice for modern appliances, recently other high quality insulations and alternatives are being used for better performances for mid to high end ovens, especially technical and commercial ovens. 

One of those is AES materials which have become a great hit as customers now often appreciate high end products and are ready to invest in return for better energy, performance, safety, and product durability. 

With the growing global competition, manufacturers are now focusing more on how the insulators will inhibit restricting the workloads of ovens.

4 high-end & Top-notch oven/range insulation you should buy

If you are looking forward to some suggestions about the best insulations available on market, here goes a list of some of the bests-

1. Ceramic Fiber Insulation Baffle Fire Blanket

Constantly withstanding a temperature of 1315C, its roller has 25inches × 24inches × 1inch. 

Being non-toxic and harmless to surroundings, Baffle fire blankets are used in ovens, stoves, furnaces, kilns, boilers etc. 

It’s also easy to use and you do not need qualified people to install it. It’s one of the popular ceramic fiber thermal insulation that has been admired by many users.

Moreover it’s easy to roll out, cut and mold. It has an average review of 4.7 stars out of 5. 

2. CM-Ceramics- Ceramic fiber insulation

It’s so far the best flame shield covering 2400°F, 31inch×24inch×1inch dimension. It’s double needled for intensity and there’s a knife included for cutting ceramic insulation. 

Made in the USA by CM-Ceramics, this product is used in ovens, forges, stoves, bead making etc. It’s highly appreciated by the users who gave it 4.9 stars.

Being flexible and lightweight, this insulation is fireproof but doesn’t eject the smell of burns. 

3. Lynn Manufacturing Kaowool Ceramic Fiber Insulation

This insulation is a robust stuff that works great in fireplaces, pizza ovens, blacksmith forge, wielding, chimney lining, jewelry making etc. 

Kaowool ceramic insulation can resist direct flame, endure ongoing use at 2400°F that ultimately melts at 3200°F.

The dimensions are about 1″ ×24″ ×32″. It’s pretty smooth to cut and install without much hassle.

As a superior insulation it received great compliments with 4.8 stars. 

4. US Energy Products (3MM Reflective Foam Insulation Shield) 

This insulation can be used outdoors or indoors as it’s absolutely unmoved by humidity or moisture and doesn’t induce the expansion of fungi or mildew.

Thermal insulation shield radiant barrier is 24″×10ft that is 3MM. Product dimensions are 24″ ×5″×5″, easy to cut and fit anywhere as the weight is tiny, around 1 pound.

It also molds to uneven surfaces making it easy to work with.

It’s quite incredible that this thin sheet of insulation can hold too much heat, staples without tearing or collapsing. Hence, it’s highly suggested for insulation purposes.

You will need tapes or other means to hold it in places as it doesn’t provide adhesives. 

Can you remove insulation from the oven?

Yes, insulations are removable, replaceable as well. Ovens can run without insulation, just not in an efficient way.

It is really unwise to operate an oven after removing its insulation as it can’t keep the heat in itself which will need much more input to keep it going smoothly.

Again, uninsulated ovens are often at risk to catch fire. 

When should you replace the oven insulation?

Insulations might get damaged once in a while but if it’s extensive the insulation needs to get replaced based on the make and model. 

Average oven insulation intercedes between its original compartment and the iron case.

When the insulation is encompassed through the two elements, it gets coated with grease or other oily food elements over time limiting the material’s work efficiency as presumed.

Furthermore, it can result in the insulations being damaged, crumbling altogether. When such happens it’s required to change the insulation for better performances like before. 

Moreover, certain old-fashioned, vintage ovens might not fit in a contemporary kitchen without proper replacement of the insulations. 

Again, commercial ovens’ temperatures are higher than the kitchen ones that demand several layers of thick insulation coatings. 

How to replace oven insulation in the oven? 

When your insulation is pretty damaged or affected badly because of long time usage, moldy material, you need to replace the insulation as soon as possible otherwise the appliance can be very unproductive.

So to make sure the oven provides uninterrupted and fine services replacing the insulation in a proper way is a must.  

Replacing the insulation itself isn’t a hard thing to do but the insulation can be complicated to access. 

The tougher part of this procedure lies in dissembling the machine so you can easily reach the material on the sides and peak of the oven. 

Through a screwdriver, a wood or plastic block you have to disconnect the oven first and move it to a safer place in the room.

Then removing the oven door, you have to take off the rear access panel. You have to remove the cooktop and the side panels gradually.

Under these elements lie the top sheet of insulation. Access that, remove the outmoded insulation, install the new one with utmost care.

Finally reassembling and checking if everything is set properly you can plug in again. Here goes the link to a Youtube video for your better understanding of the whole procedure:

Final thoughts: 

In this era of constant rush and excessive overloads, ovens have become a momentous part of our life.

It no longer is confined in home rather industrial ovens are far more used for different purposes. In this regard to prevent unwanted fire accidents insulations are equally significant.

While fiberglass insulation has dominated the industry so far, currently they are being replaced by cellulose or other non-metallic insulation materials though they might cost a lot. 

However, fiberglass remains the most convenient insulation for a while, just that you need to be careful when installing it near fireplaces, lights, or any other sources of heat.

Thus you can ensure safety measures regarding insulations.
