"Two Lines" installation by David Chipperfield Architects

Installation with laminated safety glass containing SEFAR® Architecture Vision and SentryGlas® ionoplast interlayer at the London Design Festival 2011.


Situated at the Southbank Centre Square, London, the 28 identical vertical laminated glass panels with SentryGlas<sup>®</sup> ionoplast interlayer have fabric inserts with copper and aluminum coatings that ensure the strong, material-like appearance of the glass surface and create different visual experiences both inside and outside the installation.
Each of the forms consist of a series of unframed glass panels, measuring 3600 x 1200 mm (141.73 x 47.24 inch), with translucent, single-sided metal coated fabric insets embedded in laminated glass with a SentryGlas<sup>®</sup> interlayer.

The installation "Two Lines" by David Chipperfield Architects delighted and intrigued visitors to Size+Matter at Southbank Centre, one of the cornerstones of the 2011 London Design Festival. For this sensational construction, the highly renowned London architecture practice used laminated glass with SEFAR® Architecture Vision - a new and innovative fabric with a singlesided metal coating made by Swiss corporation, Sefar AG.

"Two Lines" is a sculptural dialogue between two identical forms which only differ from one another in their orientation and the metal finishes of the fabric. Each of the forms consist of a series of unframed glass panels with translucent, singlesided metal coated fabric insets embedded in laminated glass with a SentryGlas® ionoplast interlayer. The 28 identical vertical glass panels measure 3600 x 1200 mm (141.73 x 47.24 inch). At the upper end, they are connected to horizontal glass panels of up to five meters in length by means of corresponding colored metal connections. The fabric and metal connections are set 10 mm (25/64 inch) inwards on each side so as to highlight the materials used. The excellent load-bearing capacity of the "Two Lines" is a sculptural dialogue between two identical forms which only differ from one another in their orientation and the metal finishes of the fabric. Each of the forms consist of a series of unframed glass panels with SEFAR® Architecture Vision - a new and innovative fabric with a single-sided metal coating - embedded in laminated glass with a SentryGlas® interlayer. SentryGlas® interlayer also ensures the safety and stability of the whole installation.

The concept of "Two Lines" is a focus on the interplay of the orthogonal forms with simple vertical elements. The fabric inserts with copper and aluminum coatings ensure the strong material-like appearance of the glass surface, creating different visual experiences both inside and outside the installation. The scope of this creative fabric is remarkably well demonstrated by the Size+Matter project. The resulting installation "Two Lines" was situated at the Southbank Centre Square, in central London on the south side of the River Thames.

Size+Matter – a commissions programme which is part of the London Design Festival – began in 2007 with the aim of showcasing and investigating the potential of new materials. Since its conception, these annual temporary installations by participating architects, designers, and artists have been impressing interested specialists from all over the world.
