Micro-insulated sheeting in Ecotres® material

Ecoltherm™ 14 is obtained by bonding the Ecolina sheet in Ecotres to an insulating EPS layer that is CE certified to 200 kPa, with an average thickness of 12.5 mm. The Ecoltherm™ 14 panel, in addition to preventing condensation in the upper surface in critical conditions, has excellent thermal, acoustic and mechanical properties.
The line of Ecoltherm panels and accessories by Tecno Imac s.p.a. are proudly designed and manufactured in Italy, at the factory located in Via della Stazione Aurelia in Rome, and the come with a 20-year warranty.

Environmentally friendly


  • The Ecolina layer and the insulating polystyrene foam are both fully recyclable thermoplastic materials.



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

Thermal and acoustic insulation features:


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



  • The geometry and the elasticity of the material assure high degrees of curvature when laying the sheets on convex surfaces



  • Ecolina offers an exceptional value for money solution without compromising quality

The material

Ecotres 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 has specific features designed to perform certain functions: (read here to learn more).

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, in any case, never less than 70 cm.
Position the first sheet whose side is without the insulation layer and having the stamped-marking side facing towards the outside of the covered surface area; the drip edge must coincide with the lower end of the roof slope.
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 the same manner with the subsequent sheets until the last one has been laid; if necessary, adjust the width of the latter by cutting 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).



Sheet overhang

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



Lateral overlap

The lateral overlap must be done by superimposing the first free wave of the Ecoltherm to be laid, the one marked by the marking Tecno Imac, on the last of the one already laid. Be sure to always provide for fixing at the lateral overlap of the plates.



Horizontal overlap

The overlap must always be made at the support, overlapping the two plates 15 to 30 cm, depending on the slope of the plank (see table), placing the fixings at 10 cm from the edge of the plate and sealing with a curb Polymeric adhesive at about 5 cm from the upper plate extrusion.


On high-slope tiles (greater than 17 ° / 30.5%) the overlap can be done by removing the insulating layer for 15 cm (simply engraving it with a cutter) and simply overlay the plates.
