Multipor ExSal Therm system
A comfortable, healthy indoor climate in salt-contaminated buildings

Remedial work is required to deal with damp, often salt-laden masonry in former agricultural buildings, industrial sites, churches, listed and historic buildings etc. before they can be converted to residential or commercial use or restored in a healthy, resource-efficient and environmentally friendly way.
Damp masonry contaminated with salts such as nitrates, sulfates or chlorides is one of the most common building defects, alongside poor or non-existent energy-performance standards. Until now, rectifying both these defects has been a very labor-intensive and costly process.
Multipor ExSal Therm now offers a single system to remediate damp, salt-laden masonry and upgrade the energy performance of the building at the same time. The system can be applied directly to the inner surface of the damp external wall to be insulated. There is no need to dry the wall beforehand. Multipor ExSal Therm draws moisture and salts from the wall and also provides a high level of thermal insulation to create a comfortable indoor climate.
