摘要

本研究使用國產的杉木、柳杉與台灣杉壁板，結合聚苯乙烯泡沬塑膠板、聚胺基甲酸酯泡沬塑膠板與玻璃棉等隔熱材料製作內裝用木質複合壁板，以評估比較不同隔熱設計對木質複合壁板熱特性的影響。由試驗結果可以得知，3種壁板材中是以台灣杉壁板的熱抵抗與熱貫流抵抗值最大。在製成木質複合壁板後，試材的熱抵抗值均較明顯地比原單層壁板增加，顯示木質複合壁板會較單層壁板有較佳的隔熱效果。在木質複合壁板壁體中央隔熱層厚度1 cm的情況下，中央隔層加上PS板隔熱材後，會比未加隔熱材的中空木質複合壁板有較佳的隔熱效果，在中央隔熱層厚度為2 cm的情況下，則以使用PU板作為隔熱材的設計有比較好的熱阻效果，當熱傳導率值愈高時，試材熱、冷二側的表面溫差則會愈小。

The main objective of this study was to analyze the effects of different insulation design on the thermal properties of wood-based composite wall panels for interior decoration. The results indicated that Taiwan fir (＂Taiwania cryptomerioides＂) panels have higher thermal resistance and overall thermal resistance values than the other 2 kinds of wooden panels, Japan fir (＂Cryptomeria japonica＂) and China fir (＂Cunninghamia lanceolata＂). This study also combined the wooden panel and insulation materials to make interior decorative wood-based composite wall panels (WCWP) and examined their thermal properties. The results showed that WCWP has better thermal insulation effects significantly than that of the original wooden panels. The WCWP, which using Polyurethane foam (PU) as the insulation material, would have the best thermal insulation effects than the others. The temperature difference between the hot and cold side of WCWP would decrease as its thermal conductivity value increased.
