The basic structural level of the foam glass exterior insulation system should be from the inside to the outside: the bonding layer, the foam glass insulation layer, the protective layer and the facing layer, wherein the plaster layer is mainly used for leveling the wall base layer, which can ensure The foam glass is firmly adhered to the wall, and the protective layer is mainly for protecting the firmness of the intensive insulation system and preventing water seepage. The thickness of the foam glass insulation layer shall be determined according to the material and thickness of the outer wall base layer and the energy saving requirements of the outer wall. The foam glass exterior wall insulation structure can be combined with the external wall insulation structure of other organic materials as the insulation layer, and is used as a fire barrier to prevent the external wall from being burned.
Foam glass insulation board external wall insulation construction method
1. The order of operation of the wall
When the exterior wall is covered with foam glass, the base layer of the wall should be leveled, moistened without water, and the surface of the foamed glass should be cleaned with compressed air or a brush to remove the surface ash, and scraped with a toothed trowel on the back and sides. About 2mm thick bonding mortar, while scraping 2mm thick bonding mortar on the wall surface, immediately stick the foam glass on the wall surface, squeeze it tightly with the surrounding paste, and then gently tap it with a rubber hammer. Make it bond firmly, and stick the block to the block. When the excess mortar is squeezed out, it should be scraped off immediately.
2. Paving installation method
When paving, it is generally laid from top to bottom and horizontally in the horizontal direction. (It can also be from bottom to top. In the last construction, in order to avoid falling movement, support should be added to make it stick and not slippery). The seams should be horizontally aligned between each layer, and the vertical direction should be staggered. When it is not possible to paste the whole piece, it is necessary to measure the size in advance, and cut it in the desired size on the spot, and do not cut it at will.
3. Provisions for installing staples on the outer wall
For high-rise buildings with a height of more than 4m and a floor height of more than 20m, fixed Nails should be added. The spacing between the nails should be about 1.2m. The fixing point should be at the corner of the foam glass block. The anchoring depth of the wall must be 30mm.
4. Time requirements for overcoat construction
When the outer wall foam glass cover layer is applied, it should be applied after the foam glass is pasted for 2 days before the cover layer can be applied. Before the construction, the foamed glass insulation layer should be inspected. The flatness should be more than 2mm, and the gap between the plates should not be smooth. It should be done when it is full. When facing the surface coating or pasting the tile, after the surface layer mortar is hardened, the decorative layer can be applied in 1-2 days.
5. Grid cloth paving method
Remove the surface of the foamed glass insulation layer and spray it with a small amount of water to wet it. Then wipe the surface mortar 3mm. After smearing, lay the mesh cloth and press the mesh cloth into the mortar with the trowel. The lap width is about 3mm, the paving mesh should be smooth, not wrinkled, delaminated, and after the initial setting of the mortar, wipe the surface layer 2mm, and smooth, compact, and calender. If the wall design is not laid with mesh cloth, additional reinforced mesh cloth shall be added at the corner of the wall and the corner of the wall at the corner of the wall, about 100mm on each side.
