The GROUPE JAER.CH works in thermal and sound insulation.
The challenge of thermal energy is to save you on heating, while meeting the standards in force. The current trend towards "insulating paints" makes it possible to balance the diffusion of heat in the room, in particular thanks to rock wool (or stone wool), a real natural thermal insulator, and also effective for sound insulation. The use of plasterboard is common for walls, because it benefits from a high density plate core.
