Buildingtalk’s Video of the Week demonstrates how the installation of new HARDROCK Multi-Fix Recovery Board from ROCKWOOL provided a cost effective solution for a flat roof refurbishment.
Roofing Technologies specified ROCKWOOL HARDROCK Multi-Fix Recovery Board as the right solution to occasional roof leaks at Llanfair Primary School in Cowbridge in Wales.
Approximately 450m² of HARDROCK® Multi-Fix Recovery Board was supplied by Minster Insulation and Dry Lining.
HARDROCK® Multi-Fix Recovery Board
New 30mm HARDROCK® Multi-Fix Recovery Board was selected for the Llanfair Primary School flat roof refurbishment project.
HARDROCK acts as the separating layer between the new and existing membrane systems. As the bitumen would be applied using a roofing torch, the separating layer had to be compatible with this form of application, and provide a safe, non-combustible roof surface to bond too.
Specially developed for use on flat roof refurbishment projects, the recovery board was extremely quick and easy to install. It was fitted directly over the in-situ roof membrane and evened out imperfections on the existing external finish. While there is an option to install the board using either adhesive or mechanical fixings, Roofing Technologies opted to fit it with the latter.
