SEWING HEAT-INSULATED MATS ON THE BASIS OF GLASS STAPLE THIN AND THICKENED FIBERS FROM ROCKS
Technical Specifications ÒÓ Ó Â. 2.7-73.1-05434140-030-2002 (Without restriction of validity).
Sewing heat-insulated mats on the basis of glass øòàïåëüíûõ thin and óòîëùåííûõ
fibers make without a facing or with a facing with one or from two parties.
The mats are intended for thermal isolation of designs in civil, housing and industrial
construction as thermal isolation at temperature of isolated surfaces from - 260 °Ñ up to + 900°Ñ,
and also for manufacturing sound-proof and sound-proof designs, filters of gas -air and
liquid environments. The sizes it is matte should to correspond to following values:
- Length from 500 up to 5000 mm;
- Width from 500 up to 2000 mm;
- Thickness from 10 up to 100 mm.
Physicomechanical parameters of mats is should to correspond to the requirements resulted in table.
