I. Roof Construction

1. When laying glass wool felt, the veneer faces the indoor side and is perpendicular to the purlin, leaving an additional 20 cm of rolled felt on one eave, and fix it on the outer purlin with a special clamp or double-sided tape;

2. When unwinding, ensure that it is facing up and tensioned. Lay the glass wool roll felt on the other side of the eaves. Leave 20 cm more roll felt, and fix it on the outermost purlin with special clamps or double-sided tape;

3. The two rolls of cotton are connected by a stapler binding method on the veneer burr;

4. Install the roof color steel plate, remove the fixtures on the eaves on both sides, and use the reserved 20 cm veneer to close the glass wool;

5. Pay attention to maintaining the tension and alignment of the glass wool felt, and the seams between rolls are tight. When overlap is required in the longitudinal direction, the overlap joint should be arranged at the purlin;

6. According to the needs of the project, in order to avoid the occurrence of cold bridges, you can consider padding some hard insulation materials on the purlins, such as XPS;

Second, the wall construction

1. The cotton pad is facing the indoor side, unrolled from the eaves to the foot of the wall, and the glass wool roll felt is fixed to the bottom purlin with double-sided tape, leaving 20 cm more;

2. Cut the glass wool roll felt 20 cm above the top of the wall and fix it with double-sided tape;

3. Close the glass wool and install the color steel plate;

4. Pay attention to maintaining the tension and alignment of the glass wool roll felt, and the seams between rolls are tight. According to JBJ26-95 "Design Standards for Energy Efficiency of Civil Buildings", the selection criteria for glass wool are different for the same area. Generally, glass wool with high bulk density and thickness is used in areas with low temperature. In high temperature areas, glass wool with low bulk density and thickness is used.
