The ideal solution for small roof areas

The Grecolina sheet in ecotres® material is the ideal solution for covering small roofs such as those of verandas and gazebos, for agricultural buildings and livestock shelters, but also for erecting farm or construction site fences.

Environmentally friendly:

ico-v

  • Grecolina sheeting is made of ecotres® (a high-performance layered thermoplastic material patented by Tecno Imac), in part derived from recycled materials and itself 100% recyclable at the end of its life

Durable:

ico-v

  • Laboratory tests have confirmed the extreme longevity of Grecolina sheeting which comes with a 10-year Tecno Imac warranty (*)

Thermal and acoustic insulation features:

ico-v

  • The intrinsic insulation properties of the thermoplastics employed in the production of this product assure excellent thermal and acoustic characteristics

Flexible:

The material

Grecolina is a HSP® – sheeting product – High Strength Polymer is a composite layered material that has evolved from Polimglass®  (learn more about it).

HSP is obtained by the convergence of three different individually extruded thermoplastic layers at a terminal extrusion head.The result is a single sheet that is stratified in three different layers, each of which is optimised to perform certain functions:

1-top layer: solid-coloured in PMMA (Methacrylate) for colours and finishes that are perfect and highly resistant to UV, weather and environmental exposure to chemicals of any kind.

 

2-middle layer: a mixture of different polymers loaded with micronized inert material, for a low thermal expansion, good acoustic behaviour and resistance to bending.

 

3-bottom layer: thermoplastic compounds for maximum resistance to impact and chemical aggression from underneath.The result of this particular combination of thermoplastic materials is a stable and resistant synthetic product, applicable to any environmental situation, without fear of attacks of acid vapours of any kind, whether industrial or agricultural, or the most aggressive saline environments.

Assembly tips

Roof sheeting must be laid on a framework of purlins whose span interval is proportional to the prevailing loads and the inclination.
Position the first sheet with the stamped-marking side facing towards the outside of the roof. After it has been aligned, secure it with its first crest aligned to the roof superstructure.

Warning: allow for normal thermal expansion by drilling the sheet fixing holes a bit wider than the fastening screw shank diameter, typically a 10 mm hole diameter for 6.5 mm screws.

Then the second line of fastenings should be fixed to the next higher purlin.
Establish an overlap between the second and first rows and fix the line of screws through the overlap. To maintain alignment, we recommend using a reference lanyard anchored to the ends of the purlin.

Proceed in a similar manner with the subsequent sheets, up to the last. If necessary, the width of the last sheet can be adjusted by trimming it with an angle grinder. When this has been done, proceed to secure all the sheets following the indications illustrated in the figure (at least four screw-down fastenings on each sheet per purlin, on all crests on the lowermost eaves gutter purlin).


greco1

Lateral overlap

The overlap must be assured by positioning the crest of the next Grecolina sheet to be laid over the last previously laid one. Make sure to secure the next row of fastenings along the line of the overlap.

greco2

Horizontal overlap

The overlap must always be implemented along the line of the supporting purlin, to an extent of 15 to 30 cm, depending on the slope.

greco3

Sheet overhang

At the eaves gutter, the sheet overhang must not exceed 10 cm from the lowermost purlin.
