You will be faced with several product choices when you intend to install thermal insulation on your home or other property assets. Fiberglass is not the only reliable material for heat insulation. Other materials that people often use are mineral wool, cellulose, polyurethane foam, polystyrene or Styrofoam, aerogel, and others. You may also be faced with the question, “is fiberglass Flammable?” And how does it compare to other materials?

Let’s focus on fiberglass only, where it is one of the mainstays for good thermal insulation, as well as the most affordable price. Ideally, thermal insulation materials can withstand fire well, but whether fiberglass is flammable, let’s check the facts by looking at the following description:

Fiberglass R-Value

Fiberglass has an R-Value in the range of R-2.9 to R-3.8 per inch. The value is quite good, not the best, but still mid-level. As we know, the R-value is a measure to assess how resistant a material is to heat or fire. Where the higher the value, the better the coating will retain heat. The value of R is not only determined by the material but also by the thickness and density of the material.

So when you are asked whether fiberglass is flammable, the answer is of course, no. Unless this material is exposed to a certain temperature and occurs continuously, it may melt. So, pay attention to the placement of the fiberglass wisely and seek expert recommendations if necessary.

Fiberglass Thermal Insulation Manufacturing Process

To check the facts about whether fiberglass is flammable or not, we also have to know how the process is made. You don’t need to make it yourself at home because the materials and production tools are limited. But if you want to work with a particular supplier, your business partner should be transparent and be able to show the process of making their products confidently. Cooperation with fiberglass suppliers is very open, especially when you want to buy many fiberglass-based products in large quantities. These products can be resold or for use in certain projects.

In general, fiberglass insulation is made from a mixture of silica sand and limestone and soda ash. Other materials that may be added are borax, feldspar, kaolin clay, magnesite, and others. Each supplier will have a different blend, or there may be a special formula based on certain research. The mixture of these materials will increase the performance of fiberglass and lower the melting temperature to a certain hot point.

The mixture of these materials is then heated to 2,500 Fahrenheit so that it melts, and then the factory can shape it at will into fibers and filaments to make boards for thermal insulation. Certain suppliers use special coatings and lubricants to prevent products from decreasing the quality of abrasives or antistatic agents.

Can Fiberglass Cause Fire?

The answer to the question “is fiberglass flammable?” It has been answered, where this material is not flammable but still has the potential to start a fire. This material is rated to melt at temperatures above 540 degrees Celsius or above 1,000 degrees Fahrenheit. Fiberglass can melt, releasing a supply of oxygen then will support the spread of fire in the surrounding area, including on flammable objects. In this situation, fiberglass can cause a fire.

But good suppliers, such as Silicapro, equip their thermal insulation products with a special coating to protect them from potential melting from too high a temperature. On the other hand, you should also pay attention to the installation of fiberglass insulation to prevent potential melting. Among other things, avoid installing fiberglass near chimneys or other areas that are often ignited by fire.

Where to Get Good Fiberglass Thermal Insulation

A good product has to do with a good manufacturer or factory. So when you have made your choice for fiberglass in thermal insulation, your next task is to find the best supplier. You can even get recommendations for the right and effective thermal insulation installation locations when you get the right supplier.

As the best recommendation, you can cooperate with Bright Sky New Material Co Ltd. or Silicapro to get the best recommendations, excellent service, and high-quality products. Because in addition to selling good thermal insulation boards, our company also sells a variety of other fire-resistant products that you can use dynamically.

Among the products available in our company is a high-silica fiberglass cloth, high-silicon needle felt, smokescreen wall cloth, microporous nano thermal insulation board, and aerogel felt. You also don’t want to miss the other best products, namely high-silica chopped yarn, high-performance fireproof cloth, high-performance fireproof blanket (fire blanket), silicone rubber-coated fiberglass cloth, fireproof roller shutter, and heat preservation cover.

If you want to make sure, “Is fiberglass flammable?”, you can also see the various test results that we have done. Overall, all the products we launch have passed the quality test stage and even continue to experience improvements in terms of production technology, in collaboration with many reliable researchers. So, let’s work with the best suppliers to get high-quality products at affordable prices!
