The Royal Liverpool University Hospital (RLUH) is one of the busiest hospitals in the UK, with a large emergency department. However, in line with the future healthcare needs of Liverpool’s population, plans were made for a new hospital. In 2014, following several years of planning, a massive £335m redevelopment project was greenlit with the aim of creating one of the best possible hospital environments in the country.
A new 13-storey facility is expected to open in Liverpool in summer 2018. The state-of-the-art hospital will contain 646 single occupancy rooms, spread across 23 wards. Within the site, which is next to the current hospital building, there are 18 operating theatres, a 40-bed critical care unit, and 4.5km of corridors.
HVAC in hospitals
Over the last few years, the NHS has prioritised sustainable development and energy efficiency across its sites. With this in mind, developers are increasingly looking for alternative ways to conserve power and heat.
In larger buildings with extensive and sprawling conduits – such as the Royal Liverpool University Hospital – external duct insulation plays a key role in boosting operational efficiency.
Not only does ductwork insulation increase an establishment's sustainability credentials, it also provides considerable financial savings by preventing the loss of heat and energy.
In addition, premium ranges of insulation can control condensation forming on the outside of ducts, eliminating the possibility of drips falling within the building.
Throughout the new RLUH building there are tens of thousands of square meters of ductwork on each floor, which are used to heat and ventilate the hospital. Leading insulation manufacturer, Saint-Gobain Isover, was brought on board the construction project to supply the glass mineral wool (GMW) insulation for more than 60,000m² of ductwork.
Tight time frames
Thermal insulation contractor, Gill Insulation, was chosen by the primary contractor, Carillion, to specify and install the insulation pipework and ductwork on levels three to eight and level 10 within the RLUH. Based in Nottingham, Gill Insulation is a leading specialist contractor operating nationally in the HVAC and industry markets.
To complete the project, Isover’s CLIMCOVER Roll Alu2 range was selected by Gill, with specified products being 50mm in thickness. This glass mineral wool range is ideal for use in large public sector buildings and offers up to 7% thermal savings when compared to traditional stone wool ductwork solutions.
CLIMCOVER Roll Alu2 provides efficient thermal and acoustic insulation for all shapes of metal ductwork. The solution, which is made from up to 86% recycled content, is very strong, flexible and easy to handle for installers. To prevent the build-up of condensation, the product incorporates a factory-applied aluminium foil facing, which acts as an effective vapour barrier. It also boasts increased compression resistance offering a tight, high-quality finish and superior tear strength when compared to other products.
Carl Whitehead, Technical Sales Director, commented: “The RLUH project will transform the centre of Liverpool, and we’re excited to work with Gill Insulation to see our glass mineral wool products playing a role in this.
“Energy efficiency has never been more important in today’s environmentally-conscious world. Cost-effective solutions like Isover’s CLIMCOVER range support important organisations like the NHS in saving time, power and money, while they carry out their vital duties.”
Richard Drew, Managing Director of Gill Insulation, added: “The CLIMCOVER solutions were chosen because we knew they were high-quality products which were easy to handle and install. Isover also worked very closely with us throughout the project, providing a flexible service backed by a dependable supply chain.
“On such a large-scale project, where we needed to work to tight timeframes and react to changing site priorities, portability and availability were very important factors for us.”
