Sempafloor has been designed to offer thermal insulation for cold surfaces as well as some acoustic insulation. This insulating floor lining will reduce heat loss and impact noise on any type of floor, including concrete and solid floors, whilst minimising mould growth and condensation.

Instead of insulating beneath carpets with foam, that tends to sweat and cause damp issues, using Sempatap gives a 4.5mm thick layer of thermal and acoustic insulation and will remove sweat often created by foam. Rooms over areas of damp or moisture such as over passages, over driveways or over basements are particularly susceptible to rising damp so using Sempafloor in these applications can mininise the risk of condensation and moisture.

Sempatap is manufactured from latex that has a non-woven polyester surface. This surface allows carpet, vinyl, tiles and wood panels to be laid over it whilst the lining maintains a resilience to point loading. Sempatap won’t crumble or deteriorate.
