Long-length heat-insulated strips are made of canvases superthin glass staple fibers of special purpose with a facing from two parties glass or a siliceous fabric and stitched by corresponding strings. Strips is a nonflammable, not explosive and nontoxical material.

Strips are applied for heat insulation units and heat-conducting systems of the general and special purpose in various branches of a national economy.

Limiting temperature of application of strips from -50 °С up to + 450 °С (with a facing from glass fabrics) from -50°С up to +700 °С (from siliceous fabrics). Heat conductivity of strips, W/m•К should be no more:

Temperature	Norm W/m•К
(298 ± 5) К	0,040
(398 ± 5) К	0,062
(573 ± 5) К	0,095

The mass fraction of a moisture of strips should be no more than 2 %.

As covering strips apply fabrics aviation of glass lisle thread complex filaments or insulating fabrics from glass lisle thread complex filaments, and also siliceous a fabric of mark SF-11.

In the consent with the customer of a strip can be made with others covering and seam materials.
