Material requirements planning

Rectangular double lap roofing (standard pattern) Requirement = 10.000   H-ü  x B 2 = [ slate qty./m2 ] H = Stone height ü = Overlapped headlap B = Stone width Stone format: 40 x 25 cm Headlap: 8 cm overlapped (40 - 8) : 2 = 16 16 x 25 = 400 10.000 : 400 = 25  slate qty./m2

Rectangular double lap roofing (standard pattern) with squares

Rectangular double cladding at the wall

Underlay
Generally the "References for Claddings for External Walls ventilated at Rear" ["Hinweise für hinterlüftete Au?enwandbekleidungen"] apply to the underlay including the base structure.

In case of claddings for external walls not ventilated at rear they shall be logically applied as far as the joints and fasteners are concerned.

Fastening
The slates are fastened:

-          in case of concealed nailing with 2 and/or 3 corrosion-proof slate fixing nails or pins

-          in case of using cramps with 1 or 2 cramps of rust-proof steel, material number 1.4571 or copper

-          in case of concealed nailing and additional use of cramps with 2 corrosion-proof slate fixing nails or pins and one cramp or hook of rust-proof steel or copper

Note: To the extent the cladding is made on battens with cramp hooks approximately 10% of the calculated required quantity of the hooks are needed in the form of drive-in hooks on account of the crossing points of battens and counter-battens.

Rectangular overlap cladding

Partitioning of out of the straight walls Exemple Stone format: 35 x 25 cm ( Vertical partitioning ) Joint spacing : 4 mm Joint: ? stone width   = 12,5 + 0,2 = 12,7 cm Since 12.623 is less than 12.7, take the next lower integral number: 84 The vertical linings out are applied in the distance of above: 1073 : 84 = 12,77 below: 1080 : 84 = 12,86 The levelling is carried out via the joint. Note: Any potential projecting ends shall be taken into account when partitioning.

 

Open slating

Only permitted on wall surfaces!

Partitioning of out of the straight walls Stone format   35 x 25 cm (1080 - 25) : 21 = 50,2 (1073 - 25) : 21 = 49,9 Rounded to 51 pieces The vertical lining outs are carried out in a distance of above: above: 1055 : 51 = 20,7 below: 1048 : 51 = 20,5 The levelling is effected by additional overlap. Note: Any projecting ends shall be taken into account when partitioning.

Material requirements planning (open slating)

H = stone height Hü = double lap headlap B = stone width Sü = sidelap Example of calculation: Stone format: 40 x 25 cm Headlap:      4 cm ( nailing ) Sidelap: 4 cm (40 - 4) : 2 = 18* (18 x 25) + (18 x 17) = 756 10.000 : 756 = 13,23 Slates per m2 * corresponds to the space between battens
