for facing every bad weather

What is the thermotreated wood? it is a wood treated in oven at high temperature for a lot of hours, making it compact and resistent to micro organisms as bacteria and mould. In plain English, after "cooking" wood becomes very harder and resistent than its original status, almost as fossil wood, not subject to go bad as natural wood.

a noble essence as the thermotreated ash ALUSTEP emphasizes all these characteristics, making it similar to teak.


thermowood specs

  • Unchangeable: the termic treatment deep to heart, not only on surface, makes it uncrushable and keeping of these features for long lasting.
  • Resistent to aging and getting bad with high performances:  8÷10 years outside without maintenance (class 1-2 UNI CEN/TS 15083-1:2005). Absence of water inside makes impossible settleing inside to microfauna, responsible of getting bad of natural wood
  • No crakings or slivers: the mix of treatment and high quality wood gets allows to exclude any cracking or sliver along the time. Important feature for barefoot walking by the pool.
  • wearing and shocks resistent: after the thermic treatment the nobe and soft ash wood becomes an hard and compact wood for outside. High hardness allows to resist to wearing and shocks by garden fornitures.

why it is different from other woods for outside?


Le piastrelle ALUSTEP®  termo trattate non devono essere confuse con altri prodotti sul mercato che sono solo apparentemente simili.

  • Nei legni impregnati in autoclave o, peggio, solo oliati, la protezione è unicamente sullo strato superficiale ed ovviamente si perde nel tempo a causa degli agenti atmosferici (pioggia, vento) e del calpestio. 
  • Invece il legno termotrattato non si modifica nel tempo perchè tutta la struttura è stata modificata, in superficie ed all'interno: non si altera già nella prima stagione, ma si mantiene uguale stagione dopo stagione. Volendo, può essere tagliato e sagomato senza inconvenienti, perchè non marcisce sul lato tagliato.

self-locking and self-draining

SELF-LOCKING: simple male/female fastenings make positioning very easy, without any specific experience.

SELF-DRAINING: the lower frame has feet to keep highe the tile from ground, leaving water free to flow away.

friendly approach to nature

ALUSTEP® tiles are made of natural wood, and wood only: ash is treated in oven without any additive, just heating, and it's so that wood gets the warm brown color, loosing the original cream white.

Environment friend since the beginning: our ash comes from FSC certified woods only.


how to keep wood tiles always new


thermotreated ash is not affecte by bad weather, but as teak also, is sensitive to UV sun rays that make it become gray along the time. This action can be rejected by special oiling UV protective just when in place; later the oil effect can be kept by periodical maintenance, maintaining this way its warm brown color.
