Twinfix walkways protect patients and visitors from the elements at the new Clatterbridge Centre in Liverpool
A new hospital in the heart of Liverpool is part of a £162m investment in expanding and transforming cancer services across Cheshire and Merseyside.
The 11-storey Clatterbridge Cancer Centre at Liverpool Hospital delivers highly-specialist care including pioneering immunotherapy and the most advanced forms of radiotherapy to the 2.4 million people in Cheshire and Merseyside, and those in surrounding areas.
It was designed by global architects BDP, who also designed Alder Hey Children’s Hospital. Twinfix were delighted to be involved in this project which saw two of their structures incorporated in the building’s design.
Twinfix, designed, manufactured and installed two fully-sealed link corridors with aluminium frame and squared posts between the new hospital and Clatterbridge Centre.
Both structures have aluminium frames powder coated in grey RAL 7047, which complements the design of the new hospital. The roof glazing consists of Twinfix Multi-Link-Panels NF fitted with tough 16mm clear multiwall polycarbonate. The NF denotes that these panels conform to the HSE’s recommended drop test ACR[M]001:2014, achieving a Non-Fragile designation.
Each canopy has been fitted with vertical glazing and doors to protect patients and visitors from the inclement British weather.
The following information summarises the key advantages of polycarbonate as a glazing material over glass.
Compared to glass, polycarbonate sheeting with its high strength to weight ratio, is very light, but also highly resistant to shattering and damage. This shatter resistance makes this material much safer to use than glass.
The key advantage of using polycarbonate is safety. It is a safe glazing material as it has no risk of breaking, therefore during transport, installation and in situ it is a safe material to use.
A summary of key advantages is highlighted below:
- Impact resistance: Due to the virtually unbreakable characteristics of polycarbonate there will be no danger of breakage, unlike glass. During transit, installation and in situ the impact resistance of polycarbonate means that there is no risk of it cracking, leaking, or breaking and causing glass fragments or debris to fall onto people below. Use of polycarbonate fitted within our Multi-Link-Panel NF system also makes a significant contribution to compliance with working at height regulations.
- Weight: 6mm solid polycarbonate sheet weighs 7.2kg/ m2, substantially less than the glass alternative – 7.5mm laminated glass weighs 15kg/m2. Use of polycarbonate glazing can therefore offer a safer long-term solution for the building due to reducing the strain imposed on the existing structural steelwork.
- Durability/substantiality: Unlike its glass counterpart, polycarbonate will not break, therefore no costly replacement of panels is required in future, contributing to a lower whole life cost of the roof. It will withstand natural forces like severe wind, hail, and snow storms as well as building movements caused by such weather, or by trains moving underneath.
- Access Panels: Access panels can be easily fitted into our polycarbonate Multi-Link system, unlike glass where not only would this be difficult but removing a panel of glass to gain access would proof challenging and dangerous to those trying to do it.
- Environment: Polycarbonate is light in weight, therefore beneficial to the environment due to less energy being used it its manufacture, transportation and installation. In addition it can be recycled at the end of its long life span.
- Temperature resistance: Polycarbonate retains its properties at both high and low temperatures, +100C to -40C. This too helps to eliminate the maintenance costs involved in replacing broken glazing.
We believe the above demonstrates that the high-performance and sustainable benefits of polycarbonate are far superior to glass for overhead glazing applications.
