Transom closers and hook locks from Alpro have been installed in a new visitor centre at Sudeley Castle. The castle near Winchcombe in Gloucestershire lies in a 1,200-acre estate on the Costwolds.
The transom closers are being used on aluminium doors created by local, Stroud-based Hybrid Windows who work with clients on timber composite curtain walling as an enhancement for façades. The company’s Hybrid suite is the only UK timber composite fenestration range to include curtain walling. Alpro’s transom closers are a means of hydraulically controlling the opening and closing of aluminium doors. Builders and glaziers can adjust the latching and closing force created by the hydraulic valve according to the weight and height of a door, as well as type of usage. The installer points out that adjustment of closing force is vital at a site such as Sudeley , which will have varied users.
The visitor centre also features Alpro’s round mortice cylinder hook lock deadlocks which are available in both bar and hookbolt versions for sliding doors and the swing doors used on this project. The hookbolt is made from stainless steel and is a five-ply laminated construction with the centre core case hardened and with a hardened roll pin to resist hacksaw attack.
The range offered by Hybrid Windows includes products that combine long-life and low-maintenance aluminium on the outside with the high insulation performance and environmentally-focused benefits of 100pc PEFC-accredited timber to the inside. (PEFC is an international sustainable forest management organisation.)
Leonard Roberts, a director of Hybrid, said: “The Alpro transom closers are our regular choice for aluminium doors. The units do not disturb the outline of the door and the precise adjustment of closing force as well as a hold-open option help our engineers give customers the performance they want.”
