Wienerberger – the UK’s leading provider of building material solutions – has announced the latest addition to its range of leak-proof roof flashing solutions. Koraflex Plus is a high-quality lead replacement flashing solution using the same methods and tools that would be used with lead, meaning the installation process is just as easy. The product features a butyl adhesive backing, which alleviates the need for prefabrication or welding. Not only this, but the material is incredibly flexible, stretching 70% lengthways and 15% width ways.
What distinguishes Koraflex Plus from other flashing products is that it is an environmentally safe product. Having similar properties to lead, such as easy installation and appearance enhances the benefits of using Koraflex Plus. Yet, as Wienerberger’s product does not contain lead, there aren’t the drawbacks that can often be associated with this, including the negative impact it has on the environment and to those installing the material.
Koraflex Plus also does not require the application of patination oil, which can save roofers a considerable amount of time when working on a project. It is a traditional skill for a roofer to remember to use patination oil in the correct way and can be time consuming, so without the need of this, resources can be saved. With this traditional process, if the patination oil has not been applied, then there is a risk of staining and streaking from the lead flashing. However, with Koraflex Plus this challenge is removed.
Other benefits of using a lead-free product such as Koralfex Plus is that you can harvest the rainwater and be sure you are not being contaminated by lead. Being both lead and solvent-free ensures that Koraflex Plus doesn’t have the risk of any chemical leaching and makes it suitable across all roof types, including water harvesting systems. Not only this, but lead is a highly recognisable product, which can often leave it exposed to theft. Koraflex Plus is available in a standard grey but also in red and black, which can be chosen to lessen the probability of it being stolen.
The long-term value that Koraflex Plus offers is excellent; the flashing product benefits from being extremely resistant to UV and temperature variation from -40°C to 90°C, with a 15-year Wienerberger RoofSpec® guarantee and a 25-year product warranty. With the RoofSpec® guarantee, reassurance is given that the roof system will continue to perform well for years to come, with the flashing solution itself ensuring the system is watertight and leak free. It is also very highly colour stable and gives an excellent finish and quality that is durable and pleasing to the eye.
Koraflex Plus helps meet the sustainability agenda by being both lead-free and solvent-free. As a result, it doesn’t risk chemical leaching and plays a part in reducing the amount of lead in the environment. Being lead-free means that the product eliminates potential health and safety risks associated with working in close contact with the material, therefore benefits both the workers and the environment. The product is also approved by the British Board of Agrément (BBA).
