Basalt cylinders

btv-cyilindryi

Basalt cylinders are made by pouring thin basalt fiber (TBF) by synthetic binder. They are used for heat insulation of pipelines up to +250°C.
Basalt uncoated cylinders are used as the primary insulation layer. There are many different versions of the cover layer for this product. The cover layers have the form of shells and are made of fiberglass, galvanized steel, stainless steel or foil.

Basalt foil cylinders are absolutely ready for installation and do not require any additional protective layer. We recommend to use it in the absence of any mechanical influences.

Features:

  • excellent thermal insulation and sound-absorbing characteristics;
  • non-flammable, fire-resistant, fire-proof;
  • environmentally friendly (does not contain phenol-formaldehyde binder);
  • defies the aging process (service life is more than 50 years);
  • resistance to microorganisms and rodents, do not rot;
  • do not increase diffuse resistance of constructions (excellent water vapor permeability);
  • has a low hygroscopic (does not absorb moisture from the air);
  • excellent mechanical properties (vibration resistance);
  • chemical resistance to oils, acids, alkali;
  • wide temperature range of application.
