The high compression strength and tensile strength of EWB, together with its low water and moisture absorption, lasting dimension stability against temperature variations, moisture and aging, make it versatility andcompatibility with various external wall insulation systems, and keep its ever lasting thermal, acoustic and fire insulation properties.
Excellent thermal insulation--very low thermal conductivity coefficients
Excellent acoustic insulation--can reduce noise and sound transmitting
Moisture resistant, fire resistant
Good strength to resist deformation
Antisepsis, aging resistance, anticorrosion, ensuring a health environment
Stable physical and chemical properties, durable
Easy for construction; cutting at will
