Context

Cockfield Windmill in the Suffolk countryside was converted to accommodation for holiday lets. Before it was converted, the structure was just a mill stump constructed of brick with a traditional tar coating which no longer had its sails or cap.

Beech Architects worked with the client who wanted a new cap based on the traditional ‘inverted boat’ form. Beech Architects contacted AJ Laminated Beams looking for a solution using engineered wood to create the curves for the cap of the windmill. AJ Laminated Beams, in turn, contacted Metsä Wood to see if Kerto® LVL would be suitable.

Product used

Kerto® is a laminated veneer lumber (LVL) product used in all types of construction. It is produced from 3mm-thick rotary-peeled softwood veneers that are glued together to form a continuous sheet which makes it incredibly strong and dimensionally stable. The Kerto product range includes both Kerto-S, generally used for beams and Kerto-Q LVL panels, generally used for roof decks, etc.

Metsä Wood recommended the use of Kerto-Q to form the curved rib structure with each rib having a different shape and size to form the inverted boat. AJ Laminated Beams first cut the arch shapes from the Kerto-Q sheets then glued and screwed them together to form solid arches.

Mike Wells from AJ Laminated Beams said “The joints were designed with a mechanical fixing. As an extra precaution, we glued the laminations together using Cascamite glue to give as much stiffness in each joint as possible.”

The cap with all its individual ribs was fully assembled in AJ Laminated Beams' workshop, before being taken apart and making multiple deliveries to site to enable the components to be winched into place on-site.

Kerto-Q panels were very well suited to this project because the panels could be cut easily to the shapes required and then once assembled, because Kerto is light, could be easily transported to site. Alternative solutions such as Glulam would not be suitable due to its lack of flexibility and fact that the product would be very expensive.

 “It was not the most straight forward project we have undertaken and the client and his installation team were extremely insightful on, at times, a testing project.” Mike Wells AJLaminated Beams

Outcome

The renovation project is now complete and on the inside Kerto ribs are exposed. It provides a fantastic, open living space with fantastic views of Suffolk.
