Assembly procedure

The lateral overlap is half a corrugation while the head overlap, if any, will be seen to by the assembler, cutting it to maintain the pitch of the transversal rollers constant.
The sheets will be fastened with aluminium or steel drill fixings with EPDM elastomer seal.

Type and quality of the material

The sheets are in UNI 9003/3 type aluminium alloy, minimum 0,7 mm thick, H 16-19 physical state, while the surface finish consists of prepainting with a tile red coloured polyester based paint; or the sheets are in copper, minimum 0,6 mm thick; or the sheets are in prepainted galvanised steel, minimum 0,5 mm thick;
the sheets are subject to a primary pickling cycle with a 5 micron thick primer coat on both sides, while the minimum 18 micron thick prepaint finish is applied only on the outside. Average density of the insulating foam is 35 ÷ 38 Kg/m3, cwith a minimum 95% content of closed cells.

IsoCoppo Tek

Description

Roof made with metal sheets shaped to resemble a conventional tile insulated with _________ obtained with a continuous production process, sheet thickness ____ finish _______ “IsoCoppo Tek” type profile, insulation in closed cell polyurethane foam, applied to the intrados, average 15 mm thick following the nodulation of the sheet.

Assembly procedure

The lateral overlap is half a corrugation while when there is a head overlap it will be seen to by manufacturer, cutting it to maintain the pitch of the transversal rollers constant. The sheets will be fastened with aluminium or steel drill fixings with EPDM elastomer seal. If mounting on a metal framework, all necessary precautions must be taken to prevent the onset of electrochemical corrosion caused by the contact of incompatible metals.

Type and quality of the material

The sheets are in UNI EN 485-2 type aluminium alloy, minimum 0,7 mm thick, H 14-19 physical state, while the surface finish consists of prepainting with a tile red coloured polyester based paint; the sheets are in copper, minimum 0,6 mm thick; the sheets are in prepainted galvanised steel, minimum 0,5 mm thick; the sheets are subject to a primary pickling cycle with application of a 5 micron thick primer on both sides while the minimum 18 micron thick prepaint finish is applied only on the outside.

Il Coppo di Alubel

Description

Roof made with metal sheets shaped like conventional tiles, type "Il Coppo di Alubel" (51 mm high, transversal pitch 197 mm, useful sheet width 985 mm), fastened to wood or steel stringers at a centre distance of 35 cm.
The shape of the back of the sheet must have the typical appearance of a tile roof, with differentiated curving between channel and ridge and transversal rollers to reproduce the visual effect of overlapping tiles.
The sheets themselves must be all one piece with a pitch development of 12 metres. Measurements are evaluated for actual pitch development.

Assembly procedure

The lateral overlap is half a corrugation while when there is a head overlap it will be seen to by the manufacturer, cutting it to maintain the pitch of the transversal rollers constant. The sheets will be fastened with aluminium or steel drill fixings with EPDM elastomer seal. If mounting on a metal framework, all necessary precautions must be taken to prevent the onset of electrochemical corrosion caused by the contact of incompatible metals.

Type of material and quality

The sheets are in UNI 9003/3 type aluminium alloy with a minimum thickness of 0.7 mm, H 14-19 physical state, while the surface finish consists of prepainting with a tile red coloured polyester based paint; the sheets are in copper, minimum 0,6 mm thick; the sheets are in prepainted galvanised steel, minimum 0,5 mm thick; the sheets are subject to a primary pickling cycle, a 5 micron thick primer coat on both sides while the minimum 18 micron thick prepaint finish is applicable only on the outside.

INTEGRATIVE APPLICATIONS

“Aluplan” anti-condensate treatment

The metal sheets are covered at the intrados with a non-woven polyester based fabric that has an anti-condensate function, capable of retaining no less than g/m2.
“Ecotec” sound-absorbance treatment. The metal sheets are covered at the intrados with an open cell polyethylene foam sound absorbing layer, coated with a centesimal sheet of microperforated embossed aluminium.

FORMING A VENTILATED ROOF

Description

The roofing packet consists of a triple crossed framework of wood stringers which, besides housing the heat insulating material, as mentioned in the specifications, must guarantee adequate roof ventilation with air entering through the gutter area and out through the ridge area. The air inlet is protected with grids against the intrusion of birds and small animals.

“Alupermo” breathing sheath barrier

An "Alupermo” type breathable and impermeable sheath (or similar) is applied before the heat insulating material is laid which acts as a steam shield to allow controlled diffusion of ambient steam and prevent condensate from infiltrating.

MAKING OLD ASBESTOS-CEMENT ROOFS SAFE

Description and the jobs to be done

The original roof is rendered inert by treating it with a vinyl acetate based single-component fixer in an aqueous solution, applied with low pressure dispensers to prevent the fibres and dust from being dispersed in the surrounding environment.
Laying a first row of wood strips, treated with an anti-ageing impregnating substance, laid in the direction of the pitch slant at a centre distance of no more than 100 cm, with a 5 x 6 section and fastened to the original substructure with aluminium or steel self-tapping fixings.
Laying a second row of wood strips, orthogonal to the first, equally treated, with a minimum section of 4 x 5 cm, at a centre distance suitable for the new roof and fastened to the underlying strips with wood drill fixings. It is finished when the insulating material is inserted and the new roof made, both jobs to be carried out as explained above and calculated separately.

CONNECTIONS FOR AN UNVENTILATED ROOF

Horizontal ridge

Elements for the horizontal connection of two symmetrical pitches, obtained by curving and pressforming aluminium, steel or copper sheets, appropriately profiled to simulate the shape of a tile and fitted with side straps with shaped edge to follow the undulations of the sheet, supplied in lengths up to a maximum of 300 cm, laid with a minimum overlap of 150 mm after having interposed silicone sealants and fastened with suitable anchorage fixings.

Hinged horizontal ridge

Pressed elements, as described above but with a two-part profile so they can slide lengthways and thus adapt to pitches that are not perfectly symmetrical.

Slanting ridge

Elements for connecting slanting hips obtained by curving and pressforming aluminium, steel or copper sheets, consisting of three parts – the middle profiled to the shape of a tile, the sides with two micro-corrugated aluminium straps to pressure adapt to the sheet’s profile.

CONNECTIONS FOR A VENTILATED ROOF

Horizontal ventilated ridge

Elements for the horizontal connection of two symmetrical pitches, obtained by curving and pressforming aluminium, steel and copper sheets, supplied in lengths of no more than 300 cm, profiled in three parts – the middle profiled to the shape of a tile, the sides with ventilation holes and edge shaped to follow the undulations of the sheet.

Ventilated wall connection

Elements for connecting the top edge of the pitch and the vertical wall, obtained by pressforming aluminium, steel or copper sheets, consisting of a top edge to fasten to the wall with expansion bolts and silicone for sealing, and the bottom part, with ventilation holes and shaped edge that follow the undulations of the sheet.

CONNECTIONS FOR GENERIC JOINTS

Description

Connecting elements obtained by pressforming aluminium, steel or copper sheets, in the sizes, developments and thicknesses indicated in the construction drawings, to make perimeter covers, pitch-wall connection flashings, converses and gutters, with joints overlapping and riveted with silicone sealants in between all along the development of the sheet join.
