中文摘要 | 本報告係探討建築物的牆壁與屋頂藉著裝設不同隔熱材料,對各種熱特性的結果,牆壁以實木及水泥板為材料試驗之熱流密度值(Q)會隨著材料厚度的增加而減少,其熱抵抗值(R)及熱買流抵抗值(1/K),則反之。木質外壁牆及屋頂材料之熱傳導率(λ)值均小於0.02(W/m.k),與水泥板相同厚度比較時,至少低於水泥板30倍。木質構造2 by 4建築外壁牆,在內部加1塊玻璃纖維棉其厚度為4 cm,而R值及λ值皆相差3倍,加2及3塊玻璃纖維棉之λ值並無差異。屋頂材料λ值隔熱處理者為未隔熱者約10倍,隔熱材料拔熱加一塊破璃纖維棉加一塊PU foam,可達到完全隔熱保溫效果。 |
英文摘要 | The thermal effects of wood structural building wall and roof with thermal insulation material were investigated in this study. The experimental results are summarized as follows: The wooden structure building wall with solid wood and cement board materials were tested, the heat flow of wall materials decreased with increasing thickness, and the thermal resistance and overall thermal resistance of wall materials increased with increasing thickness. The thermal conductivity of wooden structure building wall and roof was <0.02(W/m.k). And It's lower than concrete board are 30 times. The thermal resistance and over thermal resistance of wood structural 2 by 4 building wall with one layer lining of glass fiber floss is 3 times greater than that without glass fiber floss lining; and the thermal effects of wood structural 2 by 4 building wall are the same as that with 2 or 3 linings of glass fiber floss. The thermal conductivity of wood structural building roof with thermal insulation material is 10 times greater than that without thermal insulation material, and complete thermal insulation can be achieved, if we use thermal insulation material with the addition of one lining of glass fiber floss and PU foam. |
