1、 Construction step 1 of external wall insulation: base course wall must be cleaned. 2. Paste extruded board: a. After the external wall concrete base course is accepted, brush a layer of interface agent, and use it after the interface agent is dry. b. Hang two vertical through lines at the internal and external corners of the external wall, and pay attention to the consistent size from the wall. When pasting in sections, snap a horizontal line at the beginning layer and hang a horizontal line according to the vertical vertical line as the control line for pasting the extruded board. Before pasting the extruded board, the starting end of the system shall be bound first, and the 20cm wide standard mesh shall be pasted with the base course to facilitate the unpacking of the extruded board. c....

Extruded board is an extruded polystyrene thermal insulation board. It is a rigid foamed plastic board made of polystyrene resin as raw material plus other raw materials, excipients and polymers, heated by special process, mixed and injected with catalyst, and then continuously extruded and molded. Its scientific name is extruded polystyrene foam for thermal insulation (XPS for short), XPS has an intact closed cell honeycomb structure, which makes the XPS board have extremely low water absorption (almost no water absorption), moisture resistance, air tightness, lightweight, corrosion resistance, low thermal conductivity, high compression resistance, ease of aging (almost no aging decomposition phenomenon in normal use), and service life
