JANUARY 07 - PASSIVENT HELPS MAINTAIN VENTILATION INTEGRITY IN STATE-OF-ART HOSPITAL

Patients at one of the UK’s first Foundation Trust hospitals can rest assured of as healthy an environment as possible through the ventilation in the wards.

Stepping Hill Hospital’s new £25million, four storey Cardiology & Surgical Unit is the largest Foundation Hospital Procure 21 contract to date, housing four theatres, a 32 bed short stay unit, 8 bed coronary care ward and 21 bed clinical management unit. The Unit at the Stockport, Greater Manchester Hospital is due for completion in the summer, and incorporates Passivent Overglass Vent Bars in the 120 aluminium windows in the facades to the habitable rooms. Each window includes two vent bars, to provide the Regulatory requirement of 8000mm2 ventilation area/habitable room.

Specified by architects for the project Taylor Young, to compliment existing windows in the adjoining hospital building, the vents were fitted into the windows by sub contractor Lakesmere. Alan Dawson of Lakesmere explained, “The Overglass Vent Bars are the only way to keep the integrity of the window. Other methods could cause air leakage, pressure equalisation and water ingress problems. Trickle ventilation had to be included in line with Building Regulations, and the use of Overglass Vent Bars is a more cost effective, and possibly healthier way, of achieving that than by using air conditioning, as they draw fresh air in from outside and do not recirculate ‘used’ air.”

Passivent Overglass Vent Bars are available in lengths from 450mm and are supplied ready fitted with a vent to provide appropriate airflow into the building and grille for protection against weather and insect ingress. The vents meet the worst case requirements of BS6375 Part 1 for resistance to water penetration.

Installed above the glass in the window frame, the aluminium Vent Bars are thermally broken and reduce risk of condensation on the vent and prevent over- or under-ventilation in the room.

Passivent is the only natural ventilation supplier to offer a 12 years insurance backed design and product warranty with the added comfort of independent BBA certification, proven in use for over 20 years. Passivent is part of the Building Product Design Group, which specialises in developing innovative yet practical ventilation and roofing products in line with changing market requirements.
