The large format of the rhomboid roof tile 44 × 44 gives the building a particularly elegant and modern appearance. Weighing only 2.6 kg/m², it is not only extremely lightweight, but the integrated fastening strips also enable a quick and thus more cost-effective installation. Only approx. five rhomboid roof tiles are required for one square metre. This also saves time. Thanks to the flat lock system and the well-distributed fastening, the rhomboid roof tile 44 × 44 is extremely storm-proof and weather-resistant.

Roofs full of character with a familiar pattern are achieved with the PREFA rhomboid roof tile. It breathes new life into a traditional and well-established roof appearance, giving it a completely new modern definition. The material is modern too: the 0.7 mm-thick coil-coated aluminium ensures maximum durability and extreme weather resistance. The perfectly coordinated all-in-one system, the low weight and the proven flat lock installation technology ensure problem-free use on new roofs and renovations.

Notes

  • The RAL values stated are merely approximate values (~), some of which may differ vastly from the original PREFA colour and, under certain circumstances, may not reflect the subjective perception of the colour. 
  • Above all for colour quality P.10, it is almost impossible to define values due to the surface structure. In addition, the PREFA Siding colours P.10 stone grey, P.10 sand brown, P.10 patina green, natural oak, patina grey, walnut and grey oak are based on natural colours made up of several different shades.
  • Coils and metal sheets plain aluminium: The guarantee does not cover surface appearance alterations caused by processing and environmental influences. Follow the instructions.
  • Metallic colours may vary in shade.
  • To identify exact colours for complementary components please consult original samples.

Due to the enlarged surface structure, it is possible to combine traditional shapes with modern accents – without sacrificing maximum durability and extreme weather resistance. Regardless of whether you want to re-roof or renovate your old roof, you can't go wrong with the rhomboid roof tile 44 x 44. You will find even more inspiration for aluminium rhomboid tiles in our Reference Gallery or Renovation Gallery. The rhomboid roof tile 44 × 44 is also available as a rhomboid façade tile – you can thus clad your roof and façade as if from a single mould.*

* This may be a special building-based solution.

The slightly smaller PREFA rhomboid roof tile 29 × 29 is equipped with a beading embossing in contrast to the 44 rhomboid tile. This not only gives the roof covering depth but also ensures even more resistance.

Do you have questions about the rhomboid roof tile 44 × 44?

It would be too easy if we could offer you a total price here and now or tell you that a roof tile or façade shingle costs such and such. But unfortunately, it’s not that easy. That’s because every PREFA roof or façade needs to be carefully budgeted by one of our master roofers.

Metal roofs can be integrated into the exterior lightning protection system in accordance with the standard ÖVE/ÖNORM EN 62305-3. PREFA flat band roof panels (Prefalz and Falzonal) are therefore permitted as a natural part of the arrester and PREFA small format components (roof tilesshingleroof panelsrhomboid roof tiles) as natural components of the conductor (installation of an additional arrester and connection to the earth). Some standards stipulate exceptions according to which, for example, property at increased risk (e.g. potentially explosive premises) must be specially designed. The integration of PREFA roof and façade systems in the exterior lightning protection system must therefore be planned depending on the specifics of property in question. Information on the necessity and type of lightning protection on a property can be obtained from a lightning protection system engineer or approved electrician. Find out more about lightning protection here.

Thanks to their light weight, PREFA roof tiles, shingles and rhomboid roof tiles, FX.12 roof panels are ideal for covering existing old roofs.

Small hail stones cannot damage a PREFA roof with a stucco surface. In the case of extremely large hail stones, as with all roofing materials, functional damage cannot be excluded. However, even in an extreme hail storm, the piercing of a PREFA roof can almost certainly be ruled out.

Aluminium materials are largely corrosion-resistant and rust-free!

Roofbuild up when using roof rhomboid tiles 44 × 44

PREFA aluminium roofs are preferably executed with a vetilated build up, whre the substrate and thermal insulation layer is separated by a ventilated gap. This means any occasional condensation can be wicked away again.

For the most part, the roof is ventilated, as can be seen in the first picture. However, the whole attic space can also be ventilated (second picture).
