Fast Flash
Self-adhesive flashing that can be used on both flat and profiled materials. The flashing material serves the same purpose and provides the same tight seal as lead.
Fast Flash® is easy to install because the entire backside is self-adhesive, and it is flexible and highly malleable due to the material's excellent stretchability and low weight.
Flexible and self-adhesive flashing for roof and facade
When it comes to roof flashing, tightness, flexibility and easy installation are key. With Fast Flash® from JUAL, you get a modern, self-adhesive flashing solution that combines all these features in one product – without the use of lead. It is the obvious choice for both new builds and renovations, meeting today’s demands for efficiency, sustainability and durability.
Whether you are working on single-family houses, apartment complexes, industrial buildings or institutional projects, Fast Flash® is a future-proof choice. The product combines the traditional role of flashing with modern requirements for environment, safety and efficiency. With Fast Flash®, you get a solution that is just as good – and in many ways better – than lead.
Lead-free and environmentally friendly flashing
Traditionally, lead has been used for flashing due to its formability and watertightness. However, lead is heavy, environmentally harmful and requires special handling. Fast Flash® has been developed as a modern alternative, delivering the same function – without the disadvantages of lead.
Advantages of the lead-free design:
- Safe and healthy for the installer
- No risks in handling or waste disposal
- Meets environmental requirements and building regulations
- Lower weight – easier to transport and work with
What is Fast Flash®?
Fast Flash® is an advanced, lead-free flashing material designed to seal transitions and joints on roofs and façades. It can be used on both flat and profiled surfaces, and its high formability makes it easy to adapt to irregular or complex areas – for example around chimneys, roof windows, ventilation penetrations and facade transitions.
The product consists of an aluminium matrix with a formable core, and the entire back is fully self-adhesive, making installation quick and simple – with no need for heat, fixings or special tools.
