Wood Tiles

Scandole result from a totally manual process using red deal and larch oils and other wood necessary for production, all of which is cut according to lunar cycles


DURATION OF THE COVERING: the age-old use of scandole, the study of roofs in the Alps which have lasted and functioned for hundreds of years mean that we can GUARANTEE that scandole covering (if carried out correctly according to our indications) will last for over one hundred years
DIMENSIONS: scandole is produced in lengths of 30/40/50 and 60cm and widths which can vary from 5 to 20cm. However, we believe that the best length is 50cm, while that of 20cm is mainly used for the first row
WEIGHT: weight can vary from 14 kg/m² to 30 kg/m² depending on the oils used in the scandole
PROTECTION: centuries of experience in the use of scandole and the study of existing coverings show that scandole doesn’t need treatment. Indeed the natural changes in colour (various hues of grey), due to the oxidization of resins is to be considered entirely normal. In the case in which colours change more drastically from the natural colour, it is possible to treat the wood with pigments
IN CASE OF FIRE: non-treated scandole, after tests with natural atmospheric agents, as required by the DIN 4102 regulations, part 7, is considered resistant to fire and heat
ROOF SLOPE: the minimum slope required so as to guarantee hold must not be less than 30%, for covering carried out in triple layers with four overlaps. For covering with less slope or double-layered, with three overlaps, an underneath waterproofing layer is absolutely necessary and the use of scandole of a minimum length of 50cm is advised
DISTANCE OR PITCH BETWEEN THE ROWS: the distance depends on the length of the scandole as follows:
       - with double layers, three overlaps of 14.5cm, 19.5cm and 24.5cm
       - with triple layers, four overlaps of 9.5 cm, 13cm and 16.5cm
AERATION: scandole covering require a sufficient and regular aeration so that it can dry out quickly and naturally. A sufficient amount of ventilation between the lower layer and the scandole covering is absolutely essential. The minimum requirement is 40mm
REQUIREMENTS: the requirements of scandole depend on the type of roof. The difference in cuts, depending on size, type and architecture, varies from 3 to 10%
THE ROOF’S FRAME AND STRUCTURE: the distance between the beams and the  rafters mustn’t be more than a cross beam of 100 cm; transversal fillets necessary for fitting the scandole must be  riveted to a heavy counter lath with rivets of a diametre no less than 2.5mm and a length of over at least 60% (if separated, with pneumatic riveter) of the fillet’s thickness. The thickness of the fillets must not be less than 40mm
FIXING THE SCANDOLE: the scandole should be fixed with anticorrosive rivets (zinc or zinc-cadmium) in conformity with DIN 17440 regulations. Each scandola must be fixed with two rivets: we advise that wide and narrow scandole are alternated, “visibile” rivets should be avoided as much as possible. For this they should be covered by the upper scandola by at least 15mm. Automatic riveting with spikes may be used as long as it is carried out according to the afore-mentioned methods
SPLICING AND FISSURES IN THE SCANDOLE: to fix the scandole it is necessary to foresee cross joint movement, normally between 3 and 5mm. The length of the joints depends on the wood’s humidity (the dryer the scandole during laying, the wider the joints should be). Lateral movement of the joints between the first and successive rows must be at least 20mm
LAYING DETAILS: for coverings carried out by our expert and qualified personnel the information cited above is considered normal procedure for the laying of scandole. For coverings carried out by clients, apart from supplying them with explanatory drawings regarding the laying of fillets, we are completely available to give further technical information or assistance in the laying procedure
