at Manchester airport

As part of a two and a half million pound extension scheme at Manchester Airport, Williams and Williams Wallspan was chosen for the curtain walling throughout the development. And to add even greater efficiency to maintenance-free Wallspan, Evoflex was chosen for all mastic sealing. Evoflex is a non- setting, non-skinning synthetic rubber based mastic and is not affected by alkali and ultra violet rays, the main deteriorating agents which attack all oil bound mastics. Evoflex remains in- definitely flexible, and having no skin, accommodates movement without deterioration.
