Soil pipe with Fast Flash

Used for flashing soil pipes. The model is designed with a double pipe and is applied when the soil pipe penetrates the roof surface. The movable double pipe is inserted into the soil pipe, where it seals tightly with a rubber ring. The soil pipe ventilation ensures a waterproof integration in the roof surface and provides an airtight extension of the soil pipe up to the outlet above the roof surface.

Flexible and secure solution for soil pipe penetrations

For any penetration of the roof surface, it is essential to ensure both waterproofing and airtightness. This is especially important for soil pipe penetrations, where the drainage system must be able to ventilate freely – without the risk of rainwater ingress or heat loss.

JUAL’s soil pipe ventilation with black Fast Flash is designed precisely for this purpose and offers a reliable, flexible, and aesthetic solution for both new builds and renovation. The product is used in roof constructions where the soil pipe must be safely led through the roof surface and finished with ventilation. It ensures proper ventilation of the drainage system and protects against negative pressure and odours.

What is Fast Flash, and why choose it?

Fast Flash is a lead-free and malleable sealing material, suitable for roof surfaces with slopes from approx. 11–55 degrees. The material easily adapts to the roof surface – such as roof tiles, corrugated sheets, or profiled roofing materials – and can be shaped around details without the need for special tools. The black colour provides a discreet and uniform appearance that matches modern roof accessories such as roof cowls, ventilation pipes, and outlets.

With Fast Flash, you achieve a flexible seal that both saves installation time and ensures a professional finish. Products with Fast Flash are easy to mount, as the entire back is self-adhesive, and because it is flexible and highly formable due to the material’s excellent stretch properties and low weight.

Tight installation with movable double pipe

This model is equipped with a double pipe, where the inner pipe is inserted directly into the soil pipe. An integrated rubber ring ensures that the connection remains airtight and stable. The outer part of the pipe functions as flashing, keeping the roof surface completely sealed around the penetration – even during rain, snow, and temperature changes.

The double pipe solution makes installation simple and precise, while also allowing for movement and compensation, for example during thermal expansion in the pipe system.
