Thermal-acoustic insulation with 25, 50, 75 or 100 mm thick rolled sheet.

The quilted sheet is composed of three layers: the first layer consists of a special felt-like 120 gsm Carbon Fiber, the second consists of various thicknesses of anti-dusting C glass wool (formaldehyde-free, free of non-fibrous material, odourless, mould-resistant, parasite-resistant and rodent-resistant); the third layer is made of the same 120 gsm Fiber. The layers are quilted together lengthwise using a 100% Kevlar thread without the use of adhesives. Class A2-s1, d0 fireproof recyclable product.

Suitable for thermal and acoustic insulation of walls, drywalls and brick walls, as well as various suspended ceiling systems.
