Removable insulation jackets (or insulation blankets) are a flexible insulation solution that plays a key role in saving energy and ensuring operational safety for industrial piping systems, valves, and machinery. Choosing the right core material—such as Rockwool T50 80kg/m3, high-performance Aerogel, or economical fiberglass (Glasswool)—will directly determine the insulation efficiency and overall project cost.
What Are Insulation Jackets and Their Benefits?
An insulation jacket is a custom-designed insulation system that can be easily wrapped around and removed from complex-shaped equipment like valves, flanges, pumps, and turbines, unlike permanent insulation methods.
The structure of an insulation jacket typically consists of 3 main layers:
- Outer Shell: Resists environmental impacts (weather, chemicals, physical damage). Common materials include Silicone fabric, Teflon, and fiberglass cloth.
- Insulation Core Layer: The “heart” of the product, determining its heat retention capability.
- Inner Liner: In direct contact with the equipment surface, it must withstand high temperatures and be non-corrosive.
Investing in insulation jackets offers many significant benefits:
- Energy Savings: Reduces heat loss from pipes and equipment, directly cutting operational costs.
- Worker Safety: Lowers the surface temperature of equipment to a safe level, preventing burn risks for engineers and workers.
- Equipment Protection: Maintains stable operating temperatures, extending machinery lifespan and reducing breakdowns.
- Flexible and Reusable: Easy to remove and reinstall for maintenance and repairs without destroying the insulation. It can be reused multiple times, optimizing lifecycle costs.
- Noise Reduction: Some materials like mineral wool also have sound-dampening properties, improving the work environment.
Detailed Comparison of 3 Common Insulation Jacket Core Materials
The choice of core material depends on the operating temperature, environment, installation space, and budget. Below is a detailed comparison between Rockwool T50 80kg/m³, Aerogel, and Fiberglass.
Rockwool (Mineral Wool) T50 – 80kg/m³ Density
Made from molten basalt rock and slag, Rockwool T50 with a density of 80kg/m³ is the most balanced and reliable choice for most industrial applications.
- Temperature Resistance: Very good, stable performance up to 650°C, with some types capable of higher temperatures.
- Thermal Performance: Good. The 80kg/m³ density creates a dense fiber structure that effectively blocks heat transfer.
- Fire Resistance: Outstanding, non-combustible, and does not produce toxic smoke.
- Moisture Resistance: Good water resistance. However, performance will decrease if it becomes fully saturated.
- Cost: Optimal, offering a balance between performance and price.
- Best Suited For: Steam pipe systems, boilers, hot gas ducts, and equipment with medium to high temperatures (250°C – 650°C).
Aerogel
Aerogel is a high-tech insulation material with an ultra-light and porous structure, offering the highest thermal performance available today.
- Temperature Resistance: Very wide operating temperature range, from cryogenic levels to around 650°C.
- Thermal Performance: Excellent. For the same thickness, Aerogel insulates many times better than traditional materials.
- Key Feature: Extremely thin and lightweight. This makes it the ideal solution for locations with severely limited installation space.
- Moisture Resistance: Very good, with hydrophobic properties.
- Cost: High, often the most expensive option.
- Best Suited For: Applications requiring absolute thermal performance in tight spaces, superheated pipelines, and the oil, gas, and petrochemical industries.
Glasswool (Fiberglass)
Made from glass fibers, this is the most common and economical insulation material.
- Temperature Resistance: Moderate, most effective at temperatures below 350°C.
- Thermal Performance: Fairly good at lower temperature ranges, but generally less effective than Rockwool at the same thickness.
- Moisture Resistance: Poor. When damp, fiberglass tends to compress, clump, and lose significant insulation capability.
- Durability: Less durable than Rockwool; can sag and lose performance over time if subjected to vibration.
- Cost: Lowest, making it a budget-friendly choice for simple applications.
- Best Suited For: HVAC duct systems, hot water pipes, and low-temperature applications in dry environments.
Guide to Choosing Insulation Jacket Materials for Specific Cases
To make the best decision, answer the following questions:
1. What is the equipment’s operating temperature?
- Below 350°C: Fiberglass (Glasswool) is an economical choice if the environment is dry.
- From 350°C – 650°C: Rockwool T50 80kg/m³ is the optimal solution in terms of performance and cost.
- Above 650°C or for a wide temperature range: Aerogel is the leading technical solution.
2. Is the installation space limited?
- Ample Space: Rockwool at an appropriate thickness will provide high efficiency at a reasonable cost.
- Extremely Tight Space: Aerogel is the only choice due to its superior thinness while still ensuring top-tier insulation performance.
3. Is the installation environment damp or exposed to chemicals?
- Indoors, dry environment: All 3 types can be used.
- Outdoors, damp, near the coast, or with chemicals: Prioritize Rockwool or Aerogel due to their superior moisture resistance. Additionally, select an outer shell made of Silicone or Teflon fabric.
4. What is your budget?
- Low budget: Fiberglass.
- Balanced performance & cost: Rockwool T50 80kg/m³.
- Maximum performance priority, regardless of cost: Aerogel.
Choosing the right core material not only helps the system operate efficiently but is also a smart investment that optimizes long-term operational and maintenance costs. For the most accurate solution, contact insulation jacket specialists for detailed advice on your specific application.

Why use removable insulation jackets instead of permanent insulation?
Removable insulation jackets allow for quick removal and reinstallation for equipment maintenance and repair, without needing to destroy and replace the insulation, saving time and money.
What is the main difference between Rockwool and Fiberglass?
Rockwool withstands higher temperatures (typically >600°C compared to <350°C for fiberglass), is more durable, and has better moisture resistance. Fiberglass has a lower cost.
Is Aerogel really worth the high cost?
Yes, in cases with extremely tight installation spaces or where absolute thermal performance is required. Aerogel’s thin profile solves problems that other materials cannot.
What is the maximum temperature an insulation jacket with Rockwool T50 80kg/m3 can withstand?
An insulation jacket using a Rockwool T50 80kg/m3 core typically performs effectively and durably at temperatures up to 650°C.
What is the average lifespan of an insulation jacket?
The lifespan of an insulation jacket depends on the material, operating environment, and frequency of removal, but it can often last for many years if selected and used correctly.
Can insulation jackets be reused?
Yes, this is one of their biggest advantages. Insulation jackets are designed to be easily removed and reinstalled multiple times, helping to optimize maintenance costs.
