Amongst a seemingly never-ending supply of lead-free flashings, Klober Wakaflex® has so far proved to be among the top performers.
BBA-certified, it is available in four colours and is ideal for all roofing abutment work. It has similar malleability to lead with the added benefit of being stretchable by up to 50 per cent in length and 15 per cent in width. With no need for a forming tool this makes it ideal for complex detailing and shaping around deeply profiled tiles and flue penetrations.
Wakaflex has a high-strength, self-adhesive Butylon® backing which provides immediate weatherproofing and on laps the backing welds to the facing to create a virtually unbreakable bond. Cut by knife or scissors, Wakaflex is not susceptible to thermal movement so can be laid in long lengths without fixing clips.
