Alternative to traditional lead flashing

Z-Led, one of the UK's leading suppliers of damp proofing solutions, has developed AluFlash as a viable, practical alternative to lead flashing.

An innovative, environmentally-friendly alternative to traditional lead flashing, which will also massively improve on-site performance is being launched by Z-Led .

Using a combination of corrosion-resistant aluminium sheet with a solvent lacquer coloured surface and self-adhesive butyl backing, AluFlash is available in two unique surface finishes depending on the application.

C The embossed surface is designed for applications requiring less complex shapes, such as pitched roof valleys, soakers and box gutters.

The unique cross-corrugated surface is designed for use where the flashing has to be moulded over and around complex shapes such as profiled roof tiles and corner junctions, and allows the Aluflash to curve and bend in more than one direction at once.

A polymer backing sheet helps keep the self adhesive butyl layer clean until required, ensuring a secure bond.

AluFlash is unaffected by temperature, can be laid effectively in hot or cold conditions and is compatible with all common roof materials- concrete, clay, slate and metal.

The material is supplied in manageable 5m rolls, in widths from 150mm- 600mm in 50mm increments, minimising wastage and time spent cutting to fit.

It does not require specialist tools or skills to install.

Site installation time and safety is therefore significantly improved.

AluFlash is available as a sheet flashing, and is also factory-fitted to all Z-Led brick and blockwork abutment and horizontal trays.

These offer all the advantages of preformed cavity trays with the added benefits of Aluflash.

Aluflash can be used wherever lead flashing would traditionally be employed- and beyond: its non-toxic construction means it is suitable for use with rainwater harvesting installations, and prevents oxidisation over time.

The surface finish can be simply wiped clean to remove site dirt and debris such as cement mortar, and comes in a traditional 'lead grey' to compliment the building aesthetics.

Z-Led commercial manager Kelly Phipps observes, "The rising price of lead has created havoc, not only increasing building costs but prompting an increase in site thefts".

"Our new AluFlash will help restore the balance, giving contractors a cost-efficient and better alternative that will also help reduce risk of theft".

"We are so confident in its performance that we will be replacing all the lead we conventionally factory-fitted to our cavity tray sets with Aluflash in the future".

Z-Led AluFlash compliments the core range of Z-Led polypropylene cavity trays which are claimed to be virtually indestructible, its range of gas and damp barrier membranes, cavity closures, acoustic fire barriers and the Capawal high performance coping system designed to provide an attractive, weather-resistant finish to parapet walls.

The company, part of the Building Product Design Group, invests in a continuous programme of research and development to bring to market innovative yet practical products in line with changing requirements.
