Knauf Drywall sounds scientific at
University
Complex designs and strict acoustic requirements in Durham University's striking new Science lecture theatres called for 'scientific' drylining solutions, that take an unusual angle on installations.
Subcontractor Plaslines completed the GBP500,000 ceilings and partitions package using Knauf Drywall's Apertura Cleaneo perforated plasterboard for walls and the Knauf Shaftwall system to line the underside of seating tiers Drylining in the university's landmark new building has been shortlisted for the Plaisterers Trophy award

Innovative design detailing and improved plasterboard waste management combine to generate significant building site savings and environmental benefits.
The new building was designed by Building Design Partnership, Glasgow, and built by Laing O'Rourke.
It has a tiered 400-seat lecture theatre on the ground floor, and two tiered 260-seat lecture theatres above it, all with floor to soffit heights in excess of 8 metres.
It also has a 160 seat, flat-floored teaching room on the top floor, and an IT Techno-cafe which supports computer-based learning and offers light snacks.

Knauf Aquapanel for natural stone finishes
Luxury bathrooms with heavy tiles or natural stone wall finishes such as marble or granite are now easy to create in drywall constructions where Aquapanel from Knauf Drywall is the tile backer.
Plaslines Director Paul Sweeney says the compact plan arrangement and the raked lecture theatre profiles created challenging internal geometric relationships between walls and ceilings.
The challenges also included a 60 minute fire rated plenum under the theatre seating, 8 metre high, 63dB Rw partitions between lecture theatres, and 8 metre high curved independent wall linings at the perimeter of the theatres and stairs.
And, as the project was located centrally within the campus, there were logistical problems for deliveries.
"At tender stage, Knauf Drywall assisted Laing O'Rourke in preparing an outline specification to meet the rigorous technical and acoustic demands of the project," says Paul Sweeney.
"The challenges were overcome by innovative design and construction".
""The plenum was needed to insulate the theatres from foyer and machine room noise.
It was constructed with a novel sloping Knauf Shaftwall system between the supporting steelwork, with a rear layer of Knauf Coreboard and two layers of 15mm Knauf Soundshield, then a Knauf MF suspended ceiling system underneath.
"The 63dB Rw partition has a twin framed I stud system, double boarded on both sides and with acoustic insulation between the frames".
"Wall linings consist of 146mm I studs, double boarded to create a 10 metre radius to the perimeter of the lecture theatres".
"Knauf Apertura Cleaneo perforated plasterboard - more usually found in ceilings - is incorporated into the lecture theatre walls to contribute to the acoustic environment within each of them." The complex geometries of the lecture theatre ceilings, each with five 500mm steps following the line of the raked floors, are formed with the Knauf MF system, lined with Knauf Wallboard.
Extra hangers and bracing were added during construction to maintain the ceilings' stability while services were installed, before boarding commenced.
Paul Sweeney says to overcome logistical problems, Knauf Drywall and distributor Sheffield Insulations, Newcastle, arranged more frequent deliveries of smaller loads than usual".
""This minimised storage on site, as materials were used as soon as they arrived".
"Overall, this was a complex project which benefited from all members of the supply chain working together to deliver a high quality building." The project has been shortlisted for the Federation of Plastering and Drylining Contractors Plaisterers Trophy in February 2008.
Plaslines was established in July 2006, following a management buyout.
The company now employs 50 tradesmen and specialises in drywall construction and finishing, suspended ceilings, structural framing systems, screeding and plastering.
