Membrane bushing

JUAL’s membrane bushing ensures a completely sealed solution for pipes, cables and ducts in vapour barriers, underroof membranes, facades and concrete decks. With high installation flexibility and compatibility with roofing felt and various other materials, it is ideal for both new construction and renovation – effectively preventing moisture, heat loss and leaks.

Sealed, flexible and professional solution for building lead-throughs

Modern construction places high demands on airtightness, moisture protection and energy efficiency. One of the major challenges is routing pipes, cables or ventilation ducts through building elements without compromising the integrity of the structure.

With JUAL’s membrane bushing, you get a flexible, robust and completely sealed solution – suitable for both new construction and renovation.

Technically strong and installer-friendly

JUAL’s membrane bushing is designed with both functionality and easy installation in mind. This means:

  • High flexibility in angles: The lead-through can be used in roof pitches between 0° and 55° as well as at the ridge
  • Compatible with roofing felt: When installed in a solid underroof with roofing felt covering, the felt can be torched directly onto the lead-through
  • Secure sealing across different layers – e.g. vapour barrier and wind barrier
  • Suitable for multiple materials: Can be used in timber, concrete and plasterboard constructions
  • Adapted to different media: Suitable for pipes, cables and ducts – regardless of material or dimension

This ensures a sealed and durable solution, whether it is a pipe lead-through in the roof or a cable lead-through through the façade.

One solution for many purposes

  • In vapour barriers – to maintain airtightness in the building envelope

  • In underroof membranes – both rigid and flexible, on roof pitches from 0° to 55°, as well as at the ridge

  • In roofing felt coverings – where the roofing felt can be torched directly onto the lead-through

  • In wind barriers and façade constructions – for routing cables and pipes safely through the building envelope

  • In concrete decks and floor structures – where fire safety or moisture protection is required

This wide range of applications makes the product a universal tool for consultants, installers and contractors who want one proven solution that can be adapted to most details in construction.

Save time and avoid errors with a proven solution

The airtightness of the building envelope is crucial for the energy performance and comfort level of buildings. Inadequate lead-throughs can result in:

  • Thermal bridges
  • Moisture accumulation
  • Mould and indoor climate issues
  • Energy loss and reduced operational reliability

With JUAL’s membrane bushing, you get a solution that prevents these problems – while saving time and costs both during construction and throughout the building’s service life.
