Xpanda 600 (sometimes referred to as Compriband) is a pre-compressed open cell polyurethane foam backed roll with a self adhesive scrim tape to assist positioning. Heavily impregnated with chemically stabilized acrylics creating flame retardant properties, Xpanda 600 remains permanently elastic and will continually self adjust after installation to keep gaps closed.
After application, this foam tape will expand to fill gaps and will adapt to uneven surfaces, providing long term thermal and acoustic insulation.
Xpanda 1-9 will expand from 1mm in its compressed state to a maximum of 9mm once unwound and applied.
At this size Xpanda will provide a water tight seal between 1-3mm, a thermal, acoustic and draught/dust seal from 4-5mm and anything larger will be purely a gap filler.
