To reduce wood waste and improve the yield of Sugi logs, the manufacturing technology of thick molded boards from Sugi barks was investigated. The fundamental technology for the utilization of thick bark boards as heated floor panels was also investigated. The results are summarized in the following four chapters.1) Fundamental properties of Sugi bark boards: The basic board properties such as mechanical properties, dimensional stability, VOC adsorption capacity, thermal conductivity, and sound insulation performance were tested using small specimens. Sugi bark boards have low strength but have good thermal insulation and VOC adsorption capacities.2) Design of embossed die and manufacture of thick, molded boards: A die with embossed pattern for heating pipes was designed. The die was attached to the upper platen of a steam injection press and 2000 x 1 000mm molded bark boards were manufactured using isocyanate resin at board density of 400 kg/m^3. Thick (45mm) boards could be manufactured at short press time of 4.5 min.3) Determination of pattern and methods of piping for heated floors: A small scale heated floor model was constructed using bark board underlayments and several types of floor materials. The materials were found to be effective for heat diffusion and heat distribution at the floor surface was uniform.4) Application of the heated floor panels: Heated floor panels from Sugi bark boards were tested in a model house. The panels can be installed easily and have high flexibility.

为减少木材浪费，提高杉材成材率，研究了杉材树皮厚模压板材的生产工艺。研究了利用厚树皮板作为采暖地板的基本工艺。1）杉皮板材的基本性能：采用小试件测试了杉皮板材的力学性能、尺寸稳定性、VOC吸附能力、导热性能、隔音性能等基本性能。杉树皮板强度低，但具有良好的隔热性和VOC吸附能力。2）压花模具设计及厚模压板的制造：设计了加热管压花模具。将模具连接到蒸汽注射压机的上压板上，并使用异氰酸酯树脂以400 kg/m^3的板密度制造2000 x 1000 mm的模制树皮板。厚（45 mm）板可以在4.5分钟的短压制时间内制造。3）确定用于加热地板的管道的模式和方法：使用树皮板衬垫和几种类型的地板材料构建小比例加热地板模型。材料被发现是有效的热扩散和热分布在地板表面是均匀的。4）加热地板面板的应用：加热地板面板从杉树皮板进行了测试，在一个模型的房子。这些面板可以很容易地安装，并具有很高的灵活性。
