polimglass® roof sheeting recalling a tile design in the Dutch style
Nordika by Tecno Imac is a polimglass® roof sheet with a characteristic low profile “Dutch tile” style; it is a valid alternative to roofing sheets based on the classic traditional curved tile design.
Nordika is a roofing sheet with a textured or semi-gloss surface whose aesthetic profile mimics Dutch tiling. It is available in attractive terracotta and slate finishes. A range of accessories and specific fittings completes this product line, the ideal solution for roofing agricultural and industrial buildings with excellent technical and aesthetic results. Nordika is entirely manufactured in Italy in Polimglass® material.

Nordika is a Polimglass® roofing sheet (learn more about it), a material made and patented by Tecno Imac 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.
The sheets should be anchored to purlins with a maximum span interval of 90 centimetres.
Position the first sheet with the stamped-marking side facing towards the outside of the roof.
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.
At this point, complete the screw-down fastenings according to the diagram shown.
