TEROS-GRAN
WARMTH-KEEPING BACKFILL MATERIAL BASED UPON GRANULATED WOODEN CHIPS
State Center of Sanitary/Emidemiology Supervision Sanitary/Emidemiology Opinion ¹ 77.01.03.214.Ï.01377.01 dated 24.01.01
TEROS-GRAN ecologically pure warmth-keeping backfill has been developed and manufactured under new original technology. TEROS-GRAN produced from granulated wooden chips using antiseptics and anti-pyrens combined with non-toxic, explosion and fire proof water soluble polymer
binder.
TEROS-GRAN conforms with first grade construction materials usable in living and public premises under construction and renovation.
TEROS-GRAN warmth-keeping backfill material features ecological purity, resistance to the micro-organisms exposure and does not maintain flammability. Recommended use: ecologically pure, safe and efficient warmth-keeping material for panel skeletons in low-storey house building.
Manufacture of the newer TEROS-GRAN warmth-keeping material provides to solve ecological problem of great importance for Russia, i.e. economically sound chips utilization to produce ecologically pure thermal insulation being the valuable construction
material.
New TEROS-GRAN warmth-keeping backfill material has the critical distinctive feature lying in its small density, ecological purity, hardness, fireproof and fungus resistance properties.
TEROS-GRAN warmth-keeping backfill material production technology is based upon implementation of serial manufactured domestic equipment, having cost 2,500 - 3,200 thousand Rubles depending on productivity.
