Tower 42, the City of London's tallest building, has enlisted the help of 3D glass engraving specialist Sky Design, to add some innovative touches to its interiors.

By utilising Sky Design's Vitrics 3D laser engraving process, Sky Design has fashion ed 110 signs for the 42 floors of the multi-office business tower block.

The Tower Limited Partnership wanted floor entrance signs to compliment the style of the building and so it commissioned Surrey-based signage specialists Signbox to source and supply these new signs.

Signbox enlisted the help of Paris-based Sky Design after working with the laser engraving expert on other significant design projects.

Sky Design is Europe's leading Vitrics 3D laser glass engraving specialist and has worked with organisations such as NAVTEQ, Vodafone and furniture designer, Arik Levy.

The signs were crafted by Sky Design from colourless glass and then engraved individually using the company's Vitrics process, which engraves inside glass without marking the surface. The glass is separated from the walls by metal spacers, which house LED's to illuminate the signs and create attractive focal points.

‘Not only are the signs in-keeping with the innovate architecture of the structure, but they will also be hardwaring - as they are not engraved on the surface of the glass, like feature signage in many similar buildings,' explained Sky Design MD, Jeremy Buckland, ‘This means that they will not erode, as surface engraved glass signage does'.
