ISD Completes Single Envelope ‘Clad Rack’ Cold Storage Facility for Global Healthcare Company Grifols

Gloucester, 30 June 2015: ISD Solutions, a leader in single envelope cold store construction, has completed a multi-million euro frozen and chilled storage facility for Grifols, a global healthcare company based in Barcelona, Spain, and one of the world’s leading producers of plasma-derived medicines.

The warehouse represents a significant investment and forms part of the company’s new International Logistics Centre on the IDA Business Park in Grange Castle, Dublin.

The 12-month project has involved the design and construction of two temperature-controlled clad-rack structures to provide centralised storage and distribution for blood plasma products. The supporting structure comprises a Jungheinrich high-rack storage system, with cranes and conveyors, which provides automated storage, sorting and retrieval, enveloped by high performance insulated panels to form a thermally efficient single envelope skin for each of the two buildings. In total 9,000m2 of PIR insulated panels were used in the construction.

ISD Solutions had total responsibility for the insulated envelope and door design, creating both a high bay has frozen chamber supporting temperatures down to -35 degrees C and an adjacent 35m high chilled storage area. Achieving an efficient airtight structure was crucial and the buildings easily exceed design specifications with test measurements of 0.4m3 /hour/m2 at 50 Pascals for both chambers.

With the largest panels measuring 18m high, the logistics of lifting and fixing these into the position required careful planning for ISD’s Special Projects Division. With over 500 construction workers involved in total on the whole logistics centre, sequencing and coordination with other trades were also critical in achieving the client’s timeframes. Conveyor and door synchronisation is crucial to the success of the facility operation and were important design considerations that ISD and Jungheinrich had to get right.

ISD Solutions pioneered the design and construction of large-scale single envelope cold store projects using self-finished composite panel technology and was chosen as the only contractor with specific experience in building similar clad rack structures. Early design input with Grifols Engineering controlling the whole project, Jungheinrich as ASRS system supplier and main contractor Stewarts Construction, also ensured a problem free build.

Ray Barry at Jungheinrich says:

“This prestigious contract required specialist sub-contractors that we selected from all over Europe. ISD Solutions was chosen as our European partner for this project because they have an outstanding track record, unique expertise in design and installation of similar facilities and the best record for air leakage (measured by BSRIA at below 0.1m3 per hour at an increased pressure of 60 pascals).”

Jason Denning, Commercial Manager of ISD Solutions says: “When designing a cladding system to high bay ‘Cladrack’ temperature controlled buildings, there are several key factors to be considered. The envelope forms part of the building system, which must accommodate high wind loads and the effect of thermal stresses on the panel. At over 35 metres high, this is one of the tallest single envelope clad-rack warehouses in which we have been involved. Working at these heights presents added construction difficulties so we have our own in-house Health and Safety expertise to ensure risk-free installation methods and HSE procedures are followed to the letter.”

This new project joins a growing number of successful ISD single envelope cold store projects for supermarket and pharmaceutical companies in the UK, Ireland and further afield. The design brings a number of benefits and provides a highly efficient air-tight structure which contributes to lower operational running costs.”
