EXTOVER 0.04-0.125 is basically covering the fire load with EXTOVER® granulate displaces oxygen and separates it from the fuel. Like glass, EXTOVER® melts at a certain temperature. The granulate absorbs a lot of heat in the form of melting energy, thereby cooling the fire and forming at the same time an impermeable layer over the fire load. A reaction with oxygen is effectively prevented.

PORAVER 0.5-1 is lightweight aggregate expanded glass granules

Poraver® 2-4 is a lightweight aggregate with a creamy white color, designed for various construction and industrial applications. Featuring a bulk density of 190 ± 20 kg/m³ and high thermal insulation properties (0.072 W/m∙K), it offers excellent crushing resistance and minimal moisture content. Made primarily from silica (70-75%), it ensures durability and versatility for sustainable building solutions​.

Poraver® 1-2 mm is a lightweight, expanded glass granulate serving as an aggregate and filler in construction materials. Its low bulk density and high thermal insulation properties enhance product performance in applications such as lightweight concrete, mortars, and plasters.
