Type of Development

Arbroath Abbey is one of the most important historic buildings in Scotland.  Founded by William the Lion in 1178 and dedicated to St. Thomas of Canterbury, this Tironensian Monastery is where Scottish Nobles signed the “Declaration of Arbroath” in 1320 which asserted Scotland’s independence from England.

Reason for Green Roof

A green roof was specified to lend sympathy to the surrounding abbey ruins.  It was also imperative that the roof be lightweight, easy to install and have a minimum maintenance programme.

Type of Roof

Bauder Extensive Green Roof System.

Size of Green Roof

385m²

Build up of Roof

Waterproofing Build-Up
Bauder Vapour Barrier, 4mm thick featuring an expandable aluminium lining and utilising SBS modified elastomeric bitumen giving total vapour impermeability and providing initial waterproofing integrity during the system’s installation.

Bauder Eurotherm Insulation, manufactured rigid CFC and HCFC free “warm roof” insulation.

Bauder Underlayer, 4mm thick highly modified with SBS elastomeric bitumen and reinforced with a very high tensile woven glass fibre or polyester carrier.

Bauder Capping Sheet, Plant-E, 5mm thick, bituminous root resistant capping sheet containing a specially formulated chemical root inhibitor.

Green Roof Build Up
Comprising drainage layer and/or moisture retention fleece.

Bauder Xero Flor Sedum Blanket, an ‘instantly green’ and established vegetation layer comprising various species of sedum and other drought resistant plants. This blanket’s unique patented geo-textile fleece with its “nylon-loop” substrate carrier layer, provides secure support for both special lightweight growing medium substrate and the established vegetation on flat and sloping roofs alike.

Comments

“Bauder’s sedum roof was ideal as it offered a natural, low maintenance roof covering which suited the various different roof forms of the new building, and sits well beside the Historic Abbey, helping the building become part of the landscape rather than compete with the Abbey itself”.
