Reddiseals introduce Xtreme Bead the UK’s first Medite® Tricoya® based primed beading for the joiner. We are proud to exclusively bring the first ‘waterproof’ timber beading to the market.

Reddiseals is the UK’s leading supplier of parting and staff beads. Xtreme Bead is a new, extremely durable fibreboard beading, suitable for use in outdoor environments or in interior wet environments. Xtreme Bead is characterised by its durability, enhanced dimensional stability and reliability. Reddiseals then pre-insert carrier into the primed beading, reducing labour time for the tradesmen.

Xtreme Bead, made from Medite® Tricoya® is a fibreboard, which has been machined to produce the beading profiles. It is manufactured using wood fibres that have undergone an acetylation process. Wood contains “free space”, which water absorbs into and releases from. This makes the wood expand and contract due to the climatic conditions. The acetylation process uses acetic anhydride, which is reacted with the wood to prevent moisture from getting into the free spaces, making it more dimensionally stable. Enzymes digest wood in these “free spaces”, which is the main reason for wood decay. Once they have been filled, it is no longer digestible, making the wood more durable.

We recommend Reddiseals Weatherpile or Sofseal Bubble Gasket to fit the carrier. Available in a primed finish and supplied in 3m lengths designed to minimise waste on your sash window, for manufacturing or renovation. The Xtreme Bead core is guaranteed for 50 years (excludes the coating, carrier and seals).
