Dimensions, the company run by Michael Dowd, continues its programme of sophisticated banner design, based on high-strength printed fabrics - as well as pvc-coated woven glass fibre, the company can now print on ptfE and silicone-woven glass fabrics. Depending on specific client and site needs, one of at least five external fixing systems can be used. The examples shown here are Waitrose, where off-the-peg marine riggings are employed, using stainless-steel extension springs to take up initial gusts in the event of high winds. Quick-release fixings allow storm riggings to take additional loading. At the National Theatre, polyester webbing straps transfer wind loads direct to the steel masts on 34 banners on three sides of the building. The straps also prevent excessive flapping.
