Damp proof screed with recycled glass content

ThermoSap is an innovative high-performance ready-to-mix damp proof floor levelling screed for residential and commercial use. Manufactured from 98% recycled glass and naturally occurring inorganic materials, ThermoSap is non-toxic, harmless and safe. This sustainable building product provides buildings and homes with thermal insulation and is vapour permeable, sound absorbent, fire resistant and completely damp proof making it ideal for ground floors and middle floors in multi-story apartments or flats, as well as basements, lift shafts & utility roofs. ThermoSap is a multi-characteristic product that is hard wearing and also easy to apply, thus helping to reduce existing material requirements and lower labour costs. In addition to this, its dry-weight of 600 Kg/m3 makes it a very light-weight material which will help to reduce the overall load on foundations. Thermosap can be finished off with a wide variety of flooring materials such as ceramic tiles, laminates, wood and natural stone.
