Austrotherm EPS granules

Austrotherm also offers (in its official price list) EPS granules — of all six grades of "white EPS" from which we make our insulation boards (A30, AF 60, AF, A100, A120 and A150). The granules are packed in the bags shown in the photo; one bag holds 2.2 m³. Our EPS granules are 2 mm to 10 mm in diameter.

Together with cement, sand, water and an additive (plasticiser) they form the basis of so-called lightweight concrete, used more and more in construction — for the fall on flat roofs, floating floors, warm industrial floors and levelling layers. EPS granules (mostly grade A30, 2 mm to 5 mm in diameter for this use) reduce the density of the concrete considerably (from 2400 kg/m³ to 400 kg/m³ and even lower!) and with it the weight of the whole structure, while greatly improving its thermal insulation and workability.

EPS granules are also used in the furniture industry — as filling for bean bags and seat sacks (5 mm to 10 mm in diameter).
