Treatment of Furniture, Textiles & Works of Art

The eco-friendly Thermo Lignum® techniques use only naturally occurring elements (air and water), sound biological principles and established laws of physics to eradicate damage-causing insects such as woodworm, moth, carpet beetle etc, in objects ranging from art to architecture: furniture, frames, sculptures, upholstery, textiles, structural timber and architectural components.

The principle behind WARMAIR is to ensure the stability of moisture in objects by maintaining Relative Humidity (RH) within a narrow band (50-55%) throughout a heating cycle from room temperature up to 52°C/125°F (the kill temperature) and back.

The mobile version of this unique and unparalleled process has evolved from the static chambers that have operated so successfully in Germany and Switzerland since the mid 1980’s, and in London since 1994.

The owners or keepers of large collections of valuable works of art and antiques can now avail themselves of our sensitive and sympathetic treatment without their property leaving the premises. This avoids unnecessary security risks, negates additional insurance cover and minimizes the handling and movement of objects. In addition, following the treatment which takes just 24-36 hours, the total absence of any noxious or odorous chemicals or gases allows immediate reuse or redisplay of the items.

Site requirements
Designed to deliver our acclaimed service to site, the fast and effective system requires 3-phase electrical power (mains or portable generator), mains water supply and level standing to become operational.
