摘要

目前普遍在屋頂隔熱工程中，隔熱材料之隔熱性能不盡理想，部分使用材料無法回收再利用，除造成自然環境嚴重污染外，且室外之熱輻射仍藉由屋頂表面傳入室內，而影響室內環境品質。
故本研究嘗試由隔熱用輕質粒料混凝土及斷熱漆兩種材料，經由多組數單一隔熱材料之熱傳導係數值實驗量測與改善過程，進而發展出複合式屋頂隔熱用建材，並進行其工程可行性實驗驗證。本研究除可提供未來建築規劃設計者參考外，應可獲得以下研究成果：
一、在本研究使用隔熱材斷熱漆試驗板片經實驗量測後，可明顯發現試驗板片熱傳導係數值較小，其隔熱性能較市售者為佳。
二、在公部門工程標準單價核定預算下，使用此種屋頂複合式隔熱材料與隔熱工程進行施作為可行性施工工法。

Currently, the heat insulation performance of heat insulation materials that are commonly used on rooftop heat insulation projects is generally not ideal. Certain parts of the used materials are unable to recycle, thus, apart from causing serious natural environmental pollution, they are even capable to transmit outdoor heat radiation to indoor through the rooftop to affect indoor living environment quality.

This study, therefore, attempts to use lightweight aggregate concrete and heat cut paint, two types of materials to solve the heat insulation problem. It is done through the thermal conductivity values on experimental surveys and improvement processes using multiple groups of sole heat insulation materials, and then to develop a compound heat insulation rooftop building material and further to carry out its experimental project in order to get a feasible confirmation. Besides capable to provide the designers as a reference in their future construction plans, this study should also be able to obtain the following research findings.

1.In this study, after experimental surveys using heat insulation material and heat cut paint on experimental boards, they have significantly proven that the thermal conductivity value of the experimental boards is smaller. Their heat insulation performance is much better than those sold in the market.
2.Under the evaluation budget of standard public engineering unit price, the using of this type of compound heat insulation rooftop material to perform heat insulation work together with heat insulation project is regarded as a possible implementation method.
