Technical data
VIND loose thermal insulation material based on cellulose
Purpose and range of applications of the construction product: Thermal insulation of construction works
Technical specification: PN-EN 15101-1:2013
Declared technical properties of a construction product:
- Thermal conductivity λ = 0,039 [w/m*k]
- Classification of reaction to fire E (PN-EN 13501-01)
Feeding density:
- uncovered thermal insulation in horizontal and moderately sloping ≤10o partitions:
– 26÷28 [kg/m3] for thermal insulation of thickness up to 25 cm,
– do 38 [kg/m3] for thermal insulation with higher thickness - thermal insulation filling closed spaces in flat roofs (≤10o) structures, and arched and sloping roofs (>10o) 42÷60 [kg/m3],
– thermal insulation filling closed spaces in inner and outer walls 50÷60 [kg/m3],
Settlement in case of loose repose at horizontal surfaces:
- for thickness of thermal insulation up to 25 cm – 10%,
- for higher thickness – 15%.
