The Thermal Insulation Capacity of Tree Bark

Open access

Abstract

Nowadays increasing emphasis is placed on improving the quality of different insulation materials, and on developing such from materials of natural origin. The present research focuses on the thermal insulation capacity of the chipped bark of different broadleaved and coniferous wood species. We examined the bark of five tree species: black locust, a poplar clone, larch, spruce, and Scotch pine and compared their insulation characteristics to the traditionally used insulation materials. Results indicate that the thermal insulation capacity of chipped tree bark is comparable to that of generally used insulation materials, such as glass wool. Moisture content influences the thermal insulation capacity of chipped bark of the five examined species. Since energy requirement of producing chipped tree bark is very low, and it contributes also to storing carbon, therefore its CO2 balance is more advantageous compared to that of traditional fibrous or foamy insulation materials.

A fakéreg hőszigetelési tulajdonságai Manapság egyre nagyobb hangsúlyt fektetnek a különböző szigetelőanyagok javítására. A tanulmány bemutatja a különböző lombos- és tűlevelű fafajok kérgének hőszigetelő képességét. Öt fafajt vizsgáltunk meg: az akácot, a Pannonia nyár klónt, az erdeifenyőt, a vörösfenyőt és a lucfenyőt. A tanulmány mind a kezdő nedvességtartalmú, mind a 12%-os nedvességtartalomra szárított kérgeket vizsgálja. A kutatás megmutatta, hogy a fakéreg hasonló hőszigetelési tulajdonságokkal rendelkezik, mint más, általánosan használt szigetelő anyagok. A fakéreg feldolgozása alacsony energiafelhasználással jár és CO2 mérlege is lényegesen jobb, mint a hagyományos szigetelő anyagok.
