This week, SDI have been in Chester and London. In Chester we installed the shutter shown in the photograph - with a few dozen handsets for users of the car park. The slats are insulated Anthracite 77mm, and are powered by a quiet and concealed tubular motor. Our roller shutter in Chester was fitted with special windlocks. Wind locks had to be developed for a garage door type slat since they are not commonly used and not available. This product replaces one which we had to remove (installed by another organisation) which had collapsed during high winds. The shutter closes automatically after two minutes, or, after a car has exited or entered the building.
Later in the week, we traveled to Kings Cross in London and made a start on two custom built roller grilles which we have designed in co-operation with the architects Pentraeth and Hall of London. The grilles had to be very tall (3.3m) and very compact (300mm roll maximum). We used a shell pattern grille from Spain, and recessed the whole thing within a construction made of CorTen steel (rusty effect alloy steel); this will be the only example of its kind in London. Photographs to follow.
