In this context, it becomes essential to find a material that combines safety and reliability, ease of installation over large areas, mechanical strength, and low thermal conductivity — and in this regard, few materials achieve such balance with the mastery of PROMASIL®.

At its core, this insulation features a homogeneous mineral matrix, primarily composed of calcium silicate, engineered for the most demanding applications that require thermal and structural reliability in perfect harmony.

Calcium Silicate

Calcium silicate is a ceramic compound formed by the reaction between calcium oxide (CaO) and silica (SiO₂). Its porous microstructure contains millions of microscopic cavities that minimize heat conduction, keeping temperatures under control even at minimal thickness.

In addition, the presence of crystalline phases such as wollastonite (CaSiO₃) and, in some cases, tobermorite, gives the material outstanding properties:

• Exceptional mechanical strength even under intense heat

• Dimensional stability through prolonged thermal cycling

• Extremely low thermal conductivity (down to 0.077 W/m·K)

• Compatibility with harsh environments, including humid, alkaline, and mildly acidic atmospheres

Fire Safety that Inspires Confidence

In industrial environments, safety is non-negotiable. being fully inorganic, the calcium silicate used in PROMASIL® acts as a true shield: it does not burn, does not emit toxic smoke, and does not contribute to flame spread.

That’s why PROMASIL® complies with stringent international fire protection standards, including:

• ASTM E84 (Surface Flame Spread Index and Smoke Developed Index)

• EN 13501-1 (Reaction to Fire for Construction Materials)

Moreover, its chemical stability prevents unwanted reactions with corrosive agents such as alkaline vapors or mild acid mists, extending its service life in chemical plants, refineries, and steelworks.

Elevating Conventional Insulation to a New Level

Beyond its excellent mineral foundation — which already provides all the benefits discussed above — PROMASIL® 1100 SUPER is further reinforced with technical opacifiers, enhancing its ability to block radiative heat transfer.

PROMASIL® also stands out for its fine grain structure and uniform pore distribution, features that improve compressive strength and performance under mechanical vibration.

Even after 12 hours of exposure at 1050 °C, its linear shrinkage is only 1.5%, making it ideal for insulating large areas that demand long-term dimensional stability.

PROMASIL® represents the most advanced and safest application of calcium silicate insulation in the industry. Its robust thermal performance, superior mechanical strength, and uncompromising fire safety make it a strategic choice for:

• 🟩 High-performance industrial furnaces and heat ducts

• 🟩 Bases for large-scale thermal and electrical equipment

• 🟩 Environments with high fire risk and strict safety requirements

• 🟩 Structures demanding exceptional stability and chemical resistance

If your industrial operation requires absolute thermal control, unrestricted safety, and durability that stands the test of time, PROMASIL® is the most complete, reliable, and intelligent insulation solution available today.
