CELENIT wood wool panels are made of fir wood coming from sustainable management forests (PEFC™ or FSC®) and mineral binders mainly Portland cement, white or grey, and marble powder. The mix of the mentioned raw materials, the density of the mixture and the inclusion of additional layers/elements give the panels specific technical properties which make them very versatile multi-purpose products for many building applications. The cellular structure of wood gives the insulation panel lightness and elasticity. The gaps between the fibres gives sound absorption and excellent ability to adhere to all forms of mortar. The presence of Portland cement gives high resistance to water and frost and superior mechanical properties such as resistance to bending and compression and high fire resistance. The products included in the present EPD are monolayer panels and are classified in two different divisions. BUILDING | CONSTRUCTION regards building insulation products, consisting mainly of grey Portland cement and 3 mm standard texture and includes the following panels: CELENIT N and N/C (monolayer, grey cement), CELENIT R, RA (monolayer with wooden laths) and RAB (same product as RA but with white cement). ACOUSTIC | DESIGN division is specific for sound absorbing applications and regards panels selected for their aesthetic quality, mainly with white Portland cement; it includes the following panels: CELENIT ABE, AB and NB (white cement and respectively extra-thin, thin and standard textures), CELENIT AE, A (grey cement and respectively extra-thin and thin textures), ABE/A2, AB/A2, AE/A2, A/A2 (same descriptions for previous boards but in Euroclass A2-s1,d0).
