Insulation for thermal protection in residential buildings (Continued)

Centrotec undertakes the installation of heat insulation for the purpose of benefiting energy reduction in the operation of heating and cooling systems. The advantages of household insulation include noise reduction and improved livability by enhancing cooling, decreasing energy loss from various cooling appliances, and ensuring home safety through the use of non-combustible materials such as fire-resistant Rockwool insulation. This choice significantly enhances safety in your living environment.

Rockwool Insulation

Insulation made from volcanic rock fibers possesses inherent stability and durability in line with nature. It is categorized under EuroClass A1 and A2 according to the EN 13501-1 standard. This certification affirms that Rockwool insulation can withstand temperatures higher than 1,000 degrees Celsius and is non-combustible. Derived from rock material, its appearance and usage are akin to animal fur, making it a natural insulation choice.

Easy and swift installation

  • Effectively prevents thermal bridges

  • Suitable for both horizontal and vertical installation, with structural robustness

  • Resistant to ignition and proficient in sound absorption

  • Ideal for internal insulation wall applications, ensuring fire resistance and fire non

  • propagation, withstanding temperatures of up to 1,000 degrees Celsius.

(Silicate Mineral Wool Insulation)

The insulation, characterized by its porous nature, is composed of sand, silica, and white cement, followed by fiber strands to enhance strength. Typically, it excludes asbestos, ensuring its non-toxicity. Calcium silicate insulation is available in both mineral fiber form and synthetic fiber form. This type of insulation possesses the ability to quickly adjust settings at varying temperatures according to specific requirements. It can be cut and modified akin to plywood sheets, while offering excellent heat resistance properties.

  • It possesses heat resistance properties.

  • Does not contain any mineral fibers, environmentally friendly.

  • Effectively absorbs sound.

  • High density and strong impact resistance.

  • Can be cut, modified, or painted over.

  • Excellent fire resistance, with low risk of ignition or propagation.


Fiberglass insulation is manufactured from finely spun glass fibers, often of lightweight and thin nature. Some factories produce it from 100% recycled glass, which is melted at high temperatures and then spun into fibers. These fibers are sprayed with a special adhesive to hold them together. Fiberglass insulation is primarily used in homes to prevent heat buildup and is commonly installed in two main locations: above the ceiling and beneath the roof.

  • Fiberglass insulation with fully covered foil on all sides provides excellent heat protection. The thicker the insulation, the better it prevents heat. Fiberglass insulation has high density and thickness, resulting in low thermal conductivity and effective heat resistance. It helps reduce the amount of heat entering a building.

  • It also acts as a sound barrier and absorbs sound due to its abundant air pockets. Its lightweight nature makes for easy installation, and it's resistant to tearing under tension. It regains its shape well after being compressed, preventing moisture and condensation accumulation when the appropriate thickness, density, and installation methods are chosen. This prevents condensation caused by temperature differences within the building's climate-controlled environment.

  • With a lifespan of over 10 years, fiberglass fibers are durable, non-nutritive for animals, insects, and fungi, and can maintain their insulation properties for an extended period.

  • It is non-combustible, tested according to ASTM E84 and B5 476 standards, making it fire-resistant and preventing moisture penetration through the use of a special non-water-absorption material.
