Vermiculite

Vermiculite insulation & fire protection: boards, paper, CNC parts and loose granulate for high temperatures.

---

Vermiculite is a naturally occurring expanded silicate mineral that, when heated during processing, unfolds into a lightweight, porous material with strong fire-resistant credentials. It is asbestos-free, non-combustible (Class A1), fibre-free and physiologically benign — an explicit reassurance worth stating, because the mineral has been confused historically with asbestos contamination, whereas the certified vermiculite we supply contradicts that association. The material withstands process temperatures of around 1100°C continuous, with a 1150°C classification temperature and a melting point above 1300°C, and ships in five complementary forms. VIREboard self-supporting panels serve fire-resistant builds, fire-rated doors, compartmentation, stove and pizza-oven hearths, and industrial furnace lining — available in four densities (375, 475, 600 and 700 kg/m³) and thicknesses from 10 mm to 105 mm. VIREpaper is thin, flexible material for gaskets, seals and thermal liners up to 500°C continuous (short-term 1150°C) — typical homes are burner mounts, exhaust assemblies and combustion housings. Pressed and CNC-formed parts are produced to drawing or sample for specific geometries: casting cores, insulation inserts and fire-stop seals, with optional press-in nuts for series production. Bagged granulate delivers loose expanded vermiculite in 25 L, 50 L and 100 L sacks or big bags for fire-stop fill, cavity insulation, lightweight aggregate in concrete mixes and as cushioning packaging media for ADR dangerous goods. Common ground across the five forms: Class A1 (non-combustible) fire rating, very low thermal conductivity (around 0.07 W/mK for granulate up through 0.12–0.22 W/mK for boards), electrically non-conducting, acid-resistant, and mineralogically stable — which is why vermiculite is a default pick wherever low weight, fire safety and a thermal barrier are needed at the same time.
