Wolfson Cystic Fibrosis Centre

PAREX EWI system chosen for new £6.6 millionCystic Fibrosis centre.

A PAREXTHERM External Wall Insulation system (EWI) is helping towards energy efficiency and the vibrant appearance of a new adult Cystic Fibrosis facility on the Nottingham University Hospitals NHS Trust City Hospital campus.

The new £6.6 million Wolfson Centre, which aims to provide a “home in hospital” when needed for around 250 adult Cystic Fibrosis patients from Nottinghamshire and surrounding counties, has been funded with major funding support from the Nottingham Hospitals Charity, The Cystic Fibrosis Trust and the community.

The new building has a light and welcoming exterior featuring a combination of Parex acrylic renders in three contrasting colours in combination with grey brickwork and fenestration.

National healthcare specialists P+HS Architects, specified the Parex insulated render system due to the versatility of the Parex range of products and systems along with the durability of the Parex finished product which was a major requirement for this project. Parex provided robust and detailed information regarding the installation of the system to the steel frame structure, which enabled seamless transitions between the adjoining cladding and façade finishes specified.

The PAREXTHERM Acrylic EWI system features white, grey and purple acrylic render finishes with its thermal performance contributing to an overall U-value of 0.19 W/m²K, ensuring both energy efficiency and high comfort levels for patients who can sometimes spend several weeks undergoing treatment at the unit.

Working on behalf of main contractor Interserve Projects Ltd, of Leicester, specialist sub-contractor Complete Rendering Solutions, of Castle Donington, applied the PAREXTHERM system to the new-build steel framed structure by fixing weather and moisture resistant RCM Renderflex external render board followed by the insulation layer of 140mm thick graphite EPS70E, which was adhesively fixed using Parex Maite with additional mechanical fixings for a curved area which forms a feature of the front elevation of the building.

A further base coat of Maite was applied incorporating Parex 355 AVU mesh embedded for enhanced reinforcement, followed by a finishing coat of Parex DPR Sand Coarse Acrylic render finish in Marble White. The curved section was formed by by bonding and fixing the insulation, then rasping to form a uniform curvature.

The walkway adjoining the new building to the main hospital was finished using the PAREXDIRECT Acrylic render system over Parex Parmurex base coat, DPR 310 primer and a specially tinted purple colour in the Parex DPR Sand Coarse Finish to provide a seamless transition into the hospital.
