T & T roofing will install the Arboflex PU liquid applied membrane, along with tapered, fire-retardant mineral wool insulation, which will also be supplied by Carlisle. All roof areas, apart from the podium, will be completed as green roofs, and the Arboflex PU 20-year system will be installed to provide excellent root resistance, along with ease and speed of installation and effective waterproofing protection.
Arboflex PU is a versatile single component liquid applied waterproofing membrane, which builds on Carlisle’s roofing portfolio, including the company’s Hertalan EPDM system and RESITRIX hybrid EPDM/bituminous membrane.
T & T Roofing will install the tapered insulation to each roof, before applying the Arboflex PU liquid over the insulation. After rollering the liquid onto the roof, T & T’s installers will lay the system’s glass fibre matt onto the wet membrane. The fibre matt provides a guide to check the correct amount of liquid has been used and, after rollering to draw the liquid through and completing an additional application, the matt is entirely absorbed, providing a seamless roof surface.
The first phase of the Neptune Wharf roofing project will complete in February 2023, with the complete development due to handover later in the year.
