Double Magply Deck Supports Sedum Roof in Bishop’s Stortford
ONE OF THE UK’s biggest housebuilders is creating a stylish new medium-rise development on the outskirts of Bishop’s Stortford. The development consists of five linked blocks with a total of 174 one, two and three-bedroom apartments located around a landscaped public realm.
Goodsyard is a brownfield site in the South Side Locks area of the popular Hertfordshire market town. It offers buyers paying from £257,500 up to £400k excellent access to local amenities and a convenient 40-minute commute into London Liverpool Street. With sustainability and the environment being a central theme to the design along with high build standards, the specification for the sedum roofs which cover three of the buildings includes a layer of 18mm Magply boards to provide a resilient and fire-resistant deck.

Bellway Homes is leading the build of the four to five storey properties using a mix of direct labour and specialist package contractors. LJ Carpentry is the joinery company responsible for installing the high performance Magply boards over a 300mm depth of fire-resisting rigid insulation as part of a low energy roof construction. The final covering of sedum and well graded soil over a single layer waterproofing membrane has been formulated to encourage local wildlife and also assist in attenuating rainwater run-off.
The Project Manager/Site Agent for Bellway Homes, Tom Taylor, commented: “The Magply was specified by our technical team to provide structural load-bearing capacity as well as the fire performance required. Installation has gone well and work is on track.”
Independently certified to offer a range of performance benefits, Magply MOS boards present a fire-safe and environmentally friendly alternative to conventional plywood or OSB products, which normally only offer a Euroclass D or E rating. Importantly the pull-out strength for 18mm Magply is in the range 3.45-4.00 Kn/m2.
Due to the increased emphasis on fire safety in residential projects over 18 metres, BBA-approved Magply’s attributes are seeing it regularly specified for the sheathing of steel and timber framed structures as well as for pattress boards internally. The different thicknesses of panels are also widely used as a substrate board for the direct application of proprietary render systems, as well as for flooring and flat or pitched roof build-ups.
All of the Magply boards for the Goodsyard project have been supplied through the local Travis Perkins branch, with manufacturer IPP Ltd having a nationwide network of stockists and being able to offer full technical support for varied applications.
