The calculation of insulation thickness for industrial piping is based on the precise analysis of four key parameters: the type of fluid, operating temperature, installation environment, and specific usage requirements.
This technical approach optimizes thermal efficiency while reducing overall energy costs by up to 24% across the network.
Custom-made removable insulation blankets provide the most effective solution for insulating singular points such as valves, flanges, and elbows — areas that typically generate heat losses equivalent to several meters of straight piping.
Methodology
La détermination de l’épaisseur d’isolant nécessite une approche sur mesure qui débute par des relevés de température et de cotation réalisés directement sur site. Cette méthode permet d’établir un chiffrage technique personnalisé qui tient compte des contraintes spécifiques de chaque installation industrielle.
L’analyse technique intègre la modélisation 3D pour les pièces complexes, permettant une conception précise des matelas isolants adaptés aux formes particulières des équipements. Cette approche garantit une adaptation parfaite aux contraintes d’encombrement et d’accessibilité rencontrées dans les installations industrielles.
Le bureau d’études élabore les plans des matelas isolants à partir de logiciels 3D spécialisés, assurant une précision millimétrique dans le dimensionnement. Cette méthode permet de traiter efficacement les espaces restreints et les configurations complexes où les solutions standardisées ne conviennent pas.
Methodology
The type of fluid directly influences the required thickness, whether it is steam, hot water, superheated water, or organic fluids.. Each fluid has specific thermal characteristics that require an adaptation of the insulating thickness to maintain optimal performance.
The installation environment plays a major role in the selection of materials and the final thickness. Indoor installations exposed to aggressive cleaning agents require specific protective materials, while outdoor installations must withstand weather conditions and UV exposure.
Usage requirements guide the calculation toward energy-saving solutions or systems adapted to spatial constraints, requiring insulation thickness to be adjusted according to targeted energy performance goals.
Operational
La laine de roche et le feutre de silice complètent la gamme des isolants selon les contraintes de température, avec des résistances thermiques s’étendant de 250°C à 1000°C. Ces matériaux sont associés à des toiles de verre et des coutures réalisées avec des fil de couture supportant jusqu’à 1100°C.
Les revêtements extérieurs combinent des toiles de verre siliconées à l’intérieur et des revêtements en PVC pour les applications extérieures. Cette combinaison assure une résistance optimale aux UV, aux intempéries et aux agressions chimiques.
On-site installation
Flanges, expansion joints, filters, and steam traps Represent critical points where thermal bridges cause significant energy losses. The thickness calculation for these components must take into account their complex geometry and maintenance accessibility.
Elbows, magnetic filters, twin circulators, and other equipment Require a specific approach due to their multidimensional shapes, which make traditional insulation difficult. After a proper assessment and measurement, custom-made insulation blankets perfectly fit these complex geometries while maintaining optimal thermal efficiency.

ENERGY SAVINGS WITH CALOMATECH
A reduction in ambient temperature of more than 7°C in technical buildings improves working conditions and reduces air conditioning needs. This reduction contributes directly to the reduction of the carbon footprint of industrial facilities.
Energy Savings Certificates (CEE) officially recognize these energy gains, allowing companies to benefit from financial aid for their energy renovation projects.

FAQS
What is an insulating blanket?
The benefits of insulating blankets
- Quick to fit: Made to the dimensions and profile of the room, the insulation blanket can be fitted in a matter of seconds.
- Easy to dismantle: Likewise, it can be dismantled in a fraction of a second, so you can improve your valve maintenance times.
- Clean: The insulation blanket does not give off dust or bits of flying insulation wool when it is dismantled.
- Lightweight: As it is made from wool and fabric, it can be easily handled by one person.
- The thickness of the thermal insulation: Its flexibility makes it easier to slide the mat between a wall and a single point where the spacing is small.
This means you can isolate a larger number of points.
What parts should be fitted with an insulating blanket?
How do I choose an insulating mattress?
- Usage requirements (energy savings / anti-bulging solution)
- Environment: The location where the insulation blanket is installed plays a key role in selecting the appropriate materials. Indoors, within technical rooms, aggressive cleaning agents can damage standard insulation fabrics. That’s why we help you identify the right materials to use (such as PTFE or ATEX-certified fabrics). Conversely, for outdoor environments, weatherproof and UV-resistant fabrics are generally recommended.
- The type of fluid: The nature of the fluid (steam, hot water, superheated water and/or organic fluid) affects the thickness of the insulation in the insulating mattress.
- Temperature: The temperature of the fluid is also a determining factor in the thermal insulation of an insulation blanket. The temperature will make a pre-selection of the insulation to be used, but the technical characteristics and maximum temperature of use of the fabric must also be taken into account.
