Airlift

Airlift is used for pressure equalization on flat roofs where overpressure can occur under the roof surface. Available in stainless steel and various types of plastic.

Airlift – effective protection against overpressure

In modern roof constructions, especially on flat roofs, it is crucial to ensure proper pressure equalisation to avoid damage to the roof build-up. During rapid temperature changes or insufficient ventilation, overpressure can occur beneath the roof surface, which in the worst case may cause blistering in the bitumen, peeling, or lifting of the roof covering. This is where JUAL’s Airlift pressure equalisation unit is the ideal solution.

Airlift is developed to manage pressure equalisation in roof constructions and ensures controlled release of overpressure, keeping the roof tight, stable, and fully functional – even over time.

What is pressure equalisation – and why is it important?

In flat roofs, overpressure can occur between the roof covering and the insulation, typically as a result of heating from solar radiation or vapour rising through the structure. If this overpressure cannot escape, it may cause the bitumen to loosen, blister, or rupture – compromising the roof’s tightness, function, and lifespan.

Airlift acts as a safety valve, allowing air and vapour to escape without letting water in. This protects the roof construction from damage, extends the roof’s lifespan, and reduces the need for repairs.

Materials and variants

JUAL’s Airlift is available in several material types, allowing you to choose the solution that best fits your project:

  • Stainless steel – for maximum durability and resistance to UV, frost, and chemicals

  • Plastic – in different types depending on requirements, e.g. ASA or PVC, which are lightweight, UV-stable, and cost-effective

All variants are designed with a focus on long lifespan, easy installation, and minimal maintenance.

Technical advice and documentation

At JUAL, we offer professional technical advice to ensure you get the optimal solution for pressure equalisation – adapted to both the roof construction and the building situation. We assist with sizing, placement, and the number of Airlift units required, depending on the roof’s size, build-up, and use.

In addition, we provide installation guides and product data sheets, making it easy to integrate Airlift in both the design phase and on site. This ensures you get a solution that not only works in practice but also documents compliance with current standards and requirements.

Our technical team is ready to answer questions, propose solutions, and provide support – before, during, and after installation. This guarantees safe, efficient, and correct implementation, whether you are working on new builds, renovation projects, or specialist tasks.
