With a total replacement of over 4,000m2, a phased schedule of works across a 2 year period was adopted to reduce the disruption to the academy as much as possible. Working with main contractor TEC Construction and Approved Contractors DFR Roofing, and Stay Dry Roofing, works commenced with the Garland Technical Manager regularly on-site to oversee the installation.
The Pool Academy roof had an existing layer of bitumen felt with mineral wool insulation, which had become the major cause of the water ingress due to the movement in the poorly designed roof system.
A labour-intensive process was soon underway, to remove the mineral wool which had been mechanically fixed to the structure, before installing a full Garland StressPly Flex Warm Roof system. The system is built up from a newly installed Vapour Control Layer. To this layer, a fully tapered insulation scheme was installed to achieve 0.18w/m2k, the current building regulation requirement, and also to move water off the roof and to the outlet points in a more efficient way. On top of the insulation, a full torch-on system including a vented base sheet and mineral embedded cap sheet was installed.
The roof also had some failing metal roof sections which were suffering from cut edge corrosion and ingress around the fixing points where the perished seals were allowing water directly into the system. This was overclad using a bar and bracket system and additional insulation, to again achieve 0.18 w/m2k, with Garland’s R-MER CLAD system with the new roof being matched to the school’s original colour scheme.
