The requirement was to meet the specification of BS1186-3 Class 2 and better. Due to the nature or Sweet Chestnut having large knots, it was opted to supply the product Finger Jointed, in turn creating an almost entirely clear product as can be seen in the images below.
Machined to profiles ex 22 x 100, 22 x 150 and 22 x 190 mm Planed all Round (PSE). The cladding installation has then been installed with face fixings. In total almost 4000 linear metres of Sweet Chestnut Finger Jointed cladding was supplied, along with associated High Pressure treated whitewood backing structure battens.
Over time the tannins will begin to exude from the Sweet Chestnut, allowing the timber to weather down to a silver / grey and allowing the building to be more visually in keeping with English Heritage’s other buildings on-site.
