GUTEX Interior Insulation

GUTEX Thermoroom interior insulation system

Thanks to wood fibre’s excellent inherent qualities, GUTEX’s ecological interior insulation system creates wholesome living spaces with a comfortable indoor climate. Interior insulation is a consideration particularly for buildings for which exterior insulation is not possible or ill advised due to the historical significance or listing of a building. The advantages offered by interior insulation include the absence of scaffolding, insusceptibility of work to weather and the possibility to retrofit buildings gradually, one space, room or apartment at a time.
