PP-3 & Roof-Nek
Roof-Pro's PP-3 & Roof-Nek risers provide the build team with a pre-fabricated detail, which offers a consistent level of quality and design for weather-proofing penetrations for pipe and cable entry in flat roof plant areas.
They avoid DIY attempts often seen on-site that become weather-proofing nightmares, and clearly define the space and route available for pipe and cable entry.
The PP-3 & Roof-Nek offer increased assurance that cable and pipe entry points can be effectively water-proofed and insulated by the roofing team.
Once installed and weathered, the building is immediately water-tight and the M&E contractors can, as and when necessary, gain access to the riser by temporarily removing the lid.
The design facilitates easy access to run cable and pipes through the mid-section into or out of the building.
The pipes and cables also exit the riser detail at the ideal height to be supported by Roof-Pro's pipe and cable supports, and therefore allow for future roof maintenance access under the building services.
PP-3
The PP-3 unit provides a water-proofed entry point to run larger cables and pipes into your building.
The PP-3 is the larger of the two riser details, and is available in 3 standard sizes, with bespoke sizes available upon request.
