Cost efficiency through reduced cleaning requirements was the reason why Pilkington Activ™ self-cleaning glass was specified for a replacement window scheme at a prominent Welsh hospital. West Wales General Hospital in Carmarthen is installing Pilkington Activ™ in Ward Block 2, with 270m2 of the glass specified by Carmarthenshire NHS Trust for the 60 replacement windows affected.
With 329 beds, the hospital is one of the largest in South Wales. Major structural repairs have been taking place throughout the past seven years since the establishment of the Carmarthenshire NHS Trust. Replacing the existing steel windows with PVCu profiles is part of the ongoing maintenance of the site and the use of Pilkington Activ™ represents the Trust’s willingness to embrace new technology and innovative materials that will save the Trust money in the long term.
“The windows are 2.5 metres high and three floors in height, therefore ongoing cleaning has always been an issue,” comments Julian Wheeler Jones of the Estates Department. “Pilkington Activ™ provides the ideal solution to costly scaffolding, working at height restrictions and cleaning maintenance costs.” Pilkington Activ™ self-cleaning glass works through a dual action function. A microscopically thin coating of titanium dioxide creates two reactions by which it continuously cleans the external surface of the glass. First, a benign chemical reaction is caused by ultra violet light, which breaks down organic dirt particles on the surface of the glass. Secondly, the coating causes rain or any water for that matter, to sheet rather than form beads, thus ‘washing’ the surface of the glass and preventing streaking. The coating breaks down and loosens dirt that has settled on the glass, ensuring that rainwater covers the surface evenly, preventing unsightly streaks. Guaranteed to last the lifetime of the glazing itself, the coating will not rub or wear away. Pilkington Activ™ continues to work even on cloudy days and at night.
Tilt-only profiles are being installed on three floors, with two more blocks scheduled for replacement using Pilkington Activ™ when the Trust’s budget is formalised for next year. The glass was supplied by Pilkington Swansea, whose relationship with the hospital began two years ago when a quantity of Pilkington K glass was supplied for replacement purposes. “Pilkington Activ™ is appropriate for any building, domestic or commercial and its use on this high profile, prominent hospital demonstrates its suitability in any situation,” says David Jones of Pilkington Swansea.
