The Kingspan KoolDuct System has provided a space-saving ductwork solution at Lancashire-based cheesemaker, Dewlay Cheese, helping to supply cool air to three new cheese presses.

The Dewlay cheesemaking dairy has been producing high quality cheeses in the village of Garstang for over 60 years. The firm takes particular pride in its Lancashire Cheese and its produce has received numerous honours at the annual International Cheese & Dairy Awards. To continue the firm’s growth and expansion, they chose to more than double their number of mechanical cheese presses. To maintain temperatures within the presses, EcoDuct installed the Kingspan KoolDuct System within the roof of the facility.

Kingspan KoolDuct boards feature a premium insulation core faced with aluminium foil which can be easily assembled into lightweight ductwork sections up to 2.95 metres in length. This simple fabrication approach was particularly beneficial on the project due to the restrictions of the site, as the Managing Director of EcoDuct explained:

“We installed all of the Kingspan KoolDuct System sections in the roof space above the factory. To limit the disruption to Dewlay, a barrier was erected above the food production areas allowing them to continue functioning as normal. The Kingspan KoolDuct sections were then fed through a hole in the side of the building. Due to the size of some of the sections required, it was assembled in separate pieces. Our installers were then able to fit the full run within the roof space itself. This wouldn’t have been possible to achieve with standard galvanised ductwork.”

The duct construction process and coupling options supported by the Kingspan KoolDuct System form secure junctions and allow air leakage rates to be reduced to a fraction of those found with typical sheet metal ductwork.

The combination of excellent thermal performance and airtightness was particularly important on this project, as the circulated air needed to be maintained at cool temperatures to protect the dairy produce within the presses. By limiting heat and air-leakage through the ductwork, cooling and fan sizes were reduced, cutting overall energy demand. In addition to reducing long-term running costs, this also fits within the firm’s commitment to sustainability and energy efficiency exemplified by the 2mW wind turbine which provides power to the site.

The Kingspan KoolDuct System is UL Listed as a Class 1 Air Duct, to Standard for Safety UL 181 (Underwriters Laboratories: Factory Made Air Ducts & Air Connectors), when fabricated to a specification clearly defined by UL. In addition, the KoolDuct board has also been assessed under the demanding responsible sourcing standard BES 6001 for which Kingspan Insulation has been awarded a certificate of ‘Excellent’ level.

Popular Welsh manufacturer, GRH Food Company, has toasted its latest expansion which is set to double its production capacity. Work on the state-of-the-art facility includes the installation of The Kingspan KoolDuct System which provides a lightweight solution for the facility’s ventilation and cooling requirements.

The expansion at the Snowdonia Business Park includes the creation of a Cheese Innovation Centre to test new trends for blends, flavours and high nutrition cheeses for UK and international markets. Overseen by mechanical contractor, DD Cooling Ltd, 800 m2 of the Kingspan KoolDuct System was installed on the Air Handling Units by delivery partners, Holders Sheet Metal Ltd.

Ductwork fabricated from the Kingspan KoolDuct System can help to reduce operational costs as it is capable of reducing air–leakage rates to a fraction of those typical of rectangular sheet metal ductwork, in addition to limiting heat transfer, which will help to maintain a controlled temperature for the cold rooms. The System can also weigh up to 75% less than ductwork constructed from galvanised sheet steel and insulated with mineral fibre. This was key to its specification, as Craig McNaught, Project Manager from Holders Sheet Metal Ltd, explained:

“Air Handling Units have been used to make servicing and cleaning easier but, with the ductwork needing to be installed on a suspended ceiling, weight was an issue. Kingspan KoolDuct was ideal as it could ensure the cool air that passes through the ducts remains unaffected by the heat generated through cheese production, and the ductwork is also much lighter than other options.”

An additional challenge for the project was access to the ductwork. Kingspan KoolDuct is pre-insulated ductwork that allows the installation to be much easier and less time-intensive than lagged ductwork as it can be installed in a single-fix.

Craig McNaught added:

“Due to access issues, the duct needed to be manufactured and assembled in the roof space. Being able to take a selection of hand tools up with the Kingspan KoolDuct meant that the project could be completed on time.”

Ductwork fabricated from The Kingspan KoolDuct System is also well suited to projects targeting high standards in energy efficiency. The system panels have been assigned a highest possible BRE Green Guide Summary Rating of A+. The Kingspan KoolDuct System is also UL Listed as a Class 1 Air Duct, to Standard for Safety UL 181 (Underwriters Laboratories: Factory Made Air Ducts & Air Connectors), when fabricated to a specification clearly defined by UL.
