Alkor Draka’s single-ply waterproofing membrane has been specified for the Sportcity mixed sport, leisure, retail and residential development in east Manchester. Alkorplan 35271 charcoal-coloured roofing membrane is being used to cover the three-block residential element of the scheme, which was developed by Countryside Properties. Approved contractor Hi-spec Cladding & Roofing installed the membrane on the roofs, which consist of timber deck, a vapour control layer and insulation boards protected by the membrane.
Keep the noise down
A sound-deadening acoustic membrane for metal roof constructions has been introduced as part of Rockwool’s SoundPro range. Rockwool Acoustic Membrane is a flexible, high-density polymer mass layer for flat roofing and standing-seam roofing systems. The product is intended for buildings where high-performance acoustic solutions are needed.
Mockbond in many colours
Lafarge Roofing’s MockBond Mini Stonewold interlocking tiles used to be available only through a special order from the Redland range, but the manufacturer has now made them regularly available with standard delivery timings on most colours. The tiles have a centre-line groove to simulate two small-format tiles.
Hepworth Drainage has launched a notice plate pack to enable contractors to provide information on the performance capabilities of chimney hearths, fireplaces and flues. To comply with Approved Document J of the Building Regulations, contractors are required to fix indelible information plates in a readily accessible position to ensure chimney installations are used only in association with appropriate appliances.
Architectural stonework maker Chilstone has produced a portico with steps and balustrade for a property in Earls Court, west London. The work involved creating a doric column and entablature, comprising lintel, frieze and cornice, all from reconstituted stone. Chilstone’s standard porticos and other products are detailed in its architectural stonework catalogue and on its CAD disk.
An 11-home development by the Walters Group in the Swansea suburb of Mumbles has been topped in Eternit Building Materials’ E3000 fibre cement slates. The houses are roofed in blue/black slate which complements the cream render of architect Huw Griffiths’ design.
The Eternit product combines a dressed edge with a smooth, semi-matt surface. The design of the roofs incorporates rooflights, hips, traditional dormers and arched dormers. There are also two conical towers situated at either end of a terrace.

The conversion of one of the former armoury buildings at Berkeley Homes’ Royal Arsenal site in east London showcases specialised glass products from HansenGlass. An extra two floors have been added to the existing building, as well as stair towers, liftshafts and balconies glazed with ThermoSpan structural bolted units and FortPlus panels. The new glazed roof to the building was also created using ThermoSpan.
Take-off proof roofs
Russell Roof Tiles has been working with property consultant Phoenix Beard on a roofing maintenance programme for Birmingham International Airport’s Vortex Protection Scheme. The scheme provides new roofing to any property suffering vortex damage – damage caused by air currents from aircraft – so durable tiles and fittings have to be specified. The fixing specification involves the nailing and clipping of each tile to the roof structure, followed by a dry fixing system from Russell. On a recently completed first phase project for 17 homes, Double Roman tiles in Cottage Red Smooth finish were specified.

Under the ridge
Moulton Roofing specified Klober Roll Fix for the ridges of two Bellway Homes projects in Milton Keynes and Wellingborough, Northamptonshire, to help meet a new NHBC standard. The standard recommends mechanical fixings for ridge tiles at gable ends and over separating walls, as required by British Standard 5534:2003. The Roll Fix vented-ridge system meets this criterion, as well as being air and vapour permeable, and installable in a single operation requiring no special tools or wet trades.
