U Europi je drvo ključni građevinski materijal koji je posljednjih godina doživio porast upotrebe u građevinarstvu. Kako bi se poboljšala njegova dimenzionalna stabilnost i trajnost, toplinska modifikacija široko je prihvaćena komercijalna tehnologija. Toplinska modifikacija je popularna tehnika koja mijenja svojstva drveta, poboljšavajući njegovu otpornost na propadanje i povećavajući njegovu dimenzijsku stabilnost. Proces uključuje zagrijavanje drveta na visoke temperature u kontroliranim uvjetima, što dovodi do hemijskih reakcija koje rezultiraju raznim fizičkim i mehaničkim promjenama. U ovom će se radu raspravljati o učincima toplinske modifikacije na fizikalna svojstva drveta, kao što su gustoća, sadržaj vlage i boja, kao i njezin utjecaj na mehanička svojstva, uključujući čvrstoću, krutost i tvrdoću. Dodatno, pregled će ispitati faktore koji utječu na stepen modifikacije, kao što su temperatura, trajanje i vrsta drveta. Na kraju, rad će zaključiti pregledom trenutnog stanja istraživanja u ovom području i identificirati potencijalne puteve za buduća istraživanja.Reference
