Wakaflex® lead-free flashing for ultimate performance

Flashing work often requires a specialist roofer and can be both time-consuming and costly. Leadwork is also potentially hazardous to the installer if strict health and safety procedures aren’t adhered to.

This has prompted the introduction of a host of lead-free flashings, Klober Wakaflex® being both one of the longest established and highest performing. BBA-certified and with a 20-year guarantee, it is ideal for all roofing abutment work and roof types including clay, concrete, slate, metal and polycarbonate. Available in, light grey, anthracite, brown and terracotta (the latter two to special order), it has an aluminium ‘honeycomb‘ mesh embedded into UV-resistant butyl rubber which gives the product similar malleability to lead but with no scrap value. Unlike lead, it can be stretched by up to 50% in length and 15% in width and with no susceptibility to thermal movement it can also be laid in long lengths without fixing clips. With no need for forming or other specialist tools Wakaflex provides lasting performance regardless of detailing complexity and can be shaped around deeply profiled tiles or seal the top saddle and roof penetrations.

Wakaflex has a high-strength, self-adhesive Butylon® backing which provides immediate weatherproofing and on laps will also chemically bond to itself to provide a totally secure seal. It is environmentally safe, presents no contamination problem with water run-off and can therefore be used with rainwater harvesting systems.No heat, solvents, adhesives or other additional means of fixing are needed and installation can take place in temperatures from minus 40 - 100⁰C, normally without priming.

Wakaflex is available from builders and roofing merchants nationwide.
