It integrates the external wall insulation and decoration functions, conforms to the development direction of building energy conservation "modularization" technology, and is an advanced technology vigorously promoted in the field of external temperature protection technology of building walls in China.

Auxiliary tools for wood carving: mainly hammer, wood file, axe and saw. The purpose of the axe is to cut a large amount of wood with the help of paring. Pay attention not to use too much force when cutting. Do not cut straight up and down. The edge of the axe should be kept at about 45 degrees with the vertical wood grain, otherwise the wood will crack. Hainan GRC component wood file is mainly used in the fine blank stage of round carving, which can replace the flat knife to smooth the chisel marks for polishing; It can also take the place of round knife or oblique knife for hollowing. The function of the wood file is also that it can quickly adjust the modeling structure in a large area, and can be used in combination with the carving knife to make the turning and turning of the figure's clothing patterns vivid and smooth, with both virtual and real effects. The shape of hammers for wooden sculptures in Hainan is flat, flat, wide and square. The dimension of hammer face can be controlled at about 7 × 5.5 × 2.5 cm. Too narrow or too thick will affect the accuracy of the hammer's landing point and the uniformity of force. There are two kinds of hammers: wooden hammers and iron hammers. The wooden hammers generally use hardwoods with a large proportion of wood, such as mahogany, boxwood, sandalwood, beech and fruit trees. The specifications can be controlled at 27 cm in length, 55 cm in width and 45 cm in thickness; The grip is round and slightly flat, and the size is suitable for holding in the hand.

The openwork carving technique is an original carving technique in Putian. There are still many "gold inlaid openwork lanterns" and "embossed flower windows" in the Palace Museum in Beijing, which all support the traditional craft charm of Putian wood carving. From the end of the Ming Dynasty to the beginning of the Qing Dynasty to the Republic of China, Putian wood carvings were mostly made of longan wood, which was rich in local production. Carved into various military officers, women or gods, antiques, supplemented by old paint painting, make the work more deep color. Zhu Bangshou, Huang Dangui, Chen Xiange and other famous painters, together with Liu Ronglin, formed a round sculpture character style characterized by Pu style military generals. So far, many figures and architectural decoration wood carvings have been left for future generations in Guandi Temple, Yuanxia Village, Jiangkou Town, Jiufeng Village, Wutang Town and other old folk houses, These masterpieces, which combine round, transparent and relief carvings, are treasures of Putian wood carving art.

Wood carving is a kind of sculpture, which is often called "folk craft" in our country. Wood carving can be divided into three categories: three-dimensional round carving, root carving and relief carving. Wood carving is a kind of work separated from carpentry, which is classified as "fine carpentry" in our country. Folk art varieties classified by carving materials. Generally, the tree species with fine and tough texture and not easy to deform are selected, such as nanmu, red sandalwood, camphor wood, cypress, ginkgo, agarwood, mahogany, longan, etc. The tree root carving art in natural form is called "tree root carving". Wood carving has round carving, relief carving, engraving or several techniques. Some are also painted to protect wood and beautify it. Generally speaking, tools for wood carving creation, such as saws, wood files, chisels, carving knives, flat shovels, axes, wood drills, wood hammers, planes, etc., can be used for root carving creation. In addition, you also need basic tools such as scissors (scissors for pruning), knives, brushes, sandpaper (cloth), coarse and fine cloth, cotton yarn, rope, etc. During special processing, such as fire roasting, steaming, and insect prevention, some tools are also needed, which can be used in general families instead of other tools.
