Top 5 Best Ceramic Fiber Board for Insulation

Whether you are a professional insulation contractor or the owner of a major architectural firm, having an affordable and reliable ceramic fiber insulation board on-hand can be a real time-saver.

Because each of these different products comes with unique advantages and features, even the cheap insulation boards can often provide high-quality solutions to specific structural challenges.

When choosing among the many available ceramic board insulation products, several factors can come into play.

What is the difference between ceramic fiber insulation board and ceramic fiber insulation?

When many people hear the term “ceramic fiber insulation,” they often imagine those soft rolls of wall insulation that typically reside between the roof rafters of home attics.

The tiny, individual ceramic fibers that comprise these massive rolls of insulation are incredibly sharp, which means that they can cause skin and respiratory disorders if the insulation contractor is not extremely careful during the installation process.

Ceramic fiber insulation board is a much safer alternative.

Manufacturers fabricate these products through a revolutionary wet-forming process using special fibers and binders to create a vacuum-packed, board-like product that is easy to manipulate, cut, shape, and even drill. 

They specifically design ceramic board products as alternative insulation solutions for high-temperature situations.

These boards come in many different brands, shapes, temperature ratings, dimensions, densities, and compressive strengths.

Many can withstand temperatures exceeding 2000 degrees Fahrenheit, and some can even resist chemical attacks and thermal shock waves.

Typical applications for ceramic fiber insulation board include:

What is the difference between calcium silicate board and ceramic board insulation?

A calcium silicate board is a premium insulation product that manufacturers specially design to withstand continuous high operational temperatures.

Manufacturers create this white, free-flowing, powdery substance by inducing a chemical reaction between calcium oxide and silica. 

Because this substance is lightweight, fire-resistant, extremely durable, and easily malleable, calcium silicate products are a popular choice among industrial-grade piping and equipment insulation contractors.

A calcium silicate board differs from the more conventional ceramic fire board in its more extreme waterproofing capabilities.

Manufacturers fabricate calcium silicate boards with a proprietary mixture of fine silica, cement, cellulose fibers, and specially selected fillers and binders.

The final product is a high-temperature insulation board that is moisture-resistant, corrosion-resistant, and exceptionally robust even under extreme heat and pressure.

When exposed to high-moisture conditions, the calcium silicate boards completely recover without loss of tensile strength.

For most professional insulation contractors, a refractory fiber board made of ceramic materials works perfectly fine.

Benefits of ceramic board insulation include:
