The Expanding Joint Sealing Tape
A clean and easy to install, Xpanda Foam Tape is a cost-effective alternative to traditional PU aerosol foam.

What is Xpanda 600?
Xpanda 600 is a pre-compressed open cell polyurethane foam backed roll with a self adhesive scrim tape to assist positioning. Heavily impregnated with chemically stabilised acrylics creating flame retardant properties.
Xpanda 600 remains permanently elastic and will continually self adjust after installation to keep gaps closed for many years.
After application, Xpanda foam tape expands to fill gaps and also adapts to uneven surfaces to provide long term thermal and acoustic insulation.

Performance
Performance rated to 600 Pascals (Driving rain) at 25% decompression. Easy to apply, improving energy efficiency in buildings as opposed to aerosol PU expanding foam. It allows for ventilation of the joint preventing mildew build up and has excellent resistance to UV and ageing. Xpanda 600 will not crack, split, bleed or dry out whilst performing continuous movement cycles during the year, in all seasons.

Applications
Ideally suited for use as a primary or secondary seal in vertical and horizontal joints of building facades (concrete, brick, stone, insulation panels) as well as metal cladding systems, window and door perimeters, curtain walling and skylights.
Ideal for use in expansion joints, joints in portable and sectional buildings, abutment seals in conservatories, timber buildings, ductwork, caravan and mobile home manufacturing. It can be over painted with any water based acrylic or latex paint and being nonmigratory, it is compatible with most caulking materials.
