REHAU trunking with 99 percent bacteria reduction
Profila data anti-microbial trunking
REHAU Profila data anti-microbial trunking reduces bacterial colony count by almost 99% according to the first detailed microbiological tests.
The analysis was carried out at the newly built Churchfields GP surgery in Bromsgrove, Worcestershire where REHAU's Profila data anti-microbial trunking had been installed for two months, and involved swabs being taken from the cable trunking and from other comparable areas such as door handles and window sills.
In order to obtain a true comparison, swabs were also taken at the same time from the old Churchfields GP surgery nearby which had been unoccupied for the same two month period.
Bacteria collected on these swabs were grown in a laboratory and incubated in an aerobic environment so that both the amount and type of bacteria present could be identified.
The findings support the claims made by REHAU when it launched its anti-microbial solution last year that it could reduce levels of bacteria including MRSA, E-coli, Salmonella and Listeria on surfaces by up to 99%.
At the new Churchfields surgery, a bacterial colony count (CFU) of just 3 was recorded on the cable trunking, compared with 228 in the old one (a 98.69% reduction).
This compared with a colony count of 215 on a comparable door handle in the new surgery and 164 on a window sill.
Overall, the comparative study between the two buildings showed the new surgery was in general less contaminated than the old one where no cleaning was being carried out, with a reduction in the mean bacterial counts in three out of the four rooms sampled.
However, there was an increase in bacterial counts in areas such as the door handle which increased from 8 to 215 and on the rubberised flooring primarily because of the impact of human traffic.
This pattern could have been expected to be repeated on the cable trunking but the bacterial counts measured suggest that it is working effectively to provide the antibacterial effect required.
At Churchfields GP surgery, electrical contractors Barrie Beard installed 400m of REHAU Profila data anti-microbial trunking to meet the power and data cabling requirements throughout.
Barrie Beard chose the REHAU solution because they had been convinced of the benefits of the anti-microbial option for use in such a busy medical environment, and the company's choice has been justified by the findings of the study.
The REHAU study was carried out by technical experts from BioCote who supply the silver ion antimicrobial technology which is incorporated into the REHAU trunking option.
As well as inhibiting the growth of bacteria and mould, trunking incorporating the ionic silver also provides an additional level of protection against microbial organisms which can cause product deterioration, discolouration and bad odours.
REHAU can supply its Profila data, COMPACT data and Bench trunking systems with the anti- microbial option on volume orders for applications including healthcare, education and nursing homes.
Case Study looks at the impact of windows, doors and curtain walling fabricated by Solar Windows using REHAU’s PVC-U and composite systems for 68 new build apartments at the Port Marine development in Bristol,all of which have been coloured grey on the exterior and white on the interior to match the contemporary design scheme.
The first REHAU FMS remote access control system has been installed in a prestigious North London home, providing individual temperature management in every heating zone plus on-demand reporting of heating and cooling statistics. REHAU’s FMS internet interface control system offers users cost-effective control of their underfloor heating or cooling system via Bluetooth, smart phone, tablet or PC.
REHAU has introduced a new RIBA-approved CPD covering the specification of doors, windows and curtain walling as part of an energy efficient project. The CPD is entitled Fenestration: Windows, Doors and Curtain Walling and explores the pros and cons of the different material types available in the UK, which materials suit which project type best and design considerations. Building Regulations are also covered in the new CPD, alongside colour and finishing options.
REHAU joined with BRE and Solar Windows to provide an insight into the requirements of Passivhaus principles and the potential benefits in terms of lower energy costs. The successful seminar was attended by representatives from local architects, surveyors, councils and health authorities from across North Wales.
A new brochure from Rehau offers fabricators, installers and specifiers further details of the Nordic Design Plus flush fitting window system, designed for new build housing projects and as a replacement for timber windows in cottages and stone built properties.
