IKO Polymeric provided their Armourplan PSG fleece-backed PVC membrane for construction workers accommodation during the 10 year construction of Hinkley Point C, the first in a new generation of nuclear power stations in the UK.

To minimise disruption to an already extremely busy project and speed up the construction, the accommodation for the construction workers was built off site in Caledonian Modular’s manufacturing plant in Newark.

Due to its ease of installation and compatibility with offsite construction projects, a PVC single ply system was chosen for the roofing project.

Having ticked so many boxes, Caledonian Modular’s design team specified IKO Polymeric’s Armourplan PSG fleece-backed PVC membrane for the waterproofing project.

IKO Polymeric have worked with Caledonian Modular in various projects in the past providing expert technical advice on project design.

Manufactured in IKO Polymeric’s BREEAM rated ‘very good’ production plant in Chesterfield with a BBA service life in excess of 30 years, Armourplan roofing membrane was the choice for the UK’s new generation first low carbon nuclear power station.

Membrane installations were carried out by Marksman Roofing in Caledonian Modular’s manufacturing facility. 44 identical roof modules were installed with Armourplan PSG membrane and shipped to the site for final installation of the 10,000m2 roof.

To construct the individual roof modules, a layer of OSB3 was bonded together with foil-faced Ecotherm insulation; then another layer of OSB3 with Armourplan PSG membrane was fully bonded to the exterior grade ply boards.
