How to deal with thermal cracking of exterior wall?
Find cause of cracking. It is possible that cracking is not caused by heat preservation itself, such as uneven settlement. At this time, don't mend the cracks first, then mend them again.
Replacement of existing insulation materials and repair of cracks. After cracking, often cause leakage passage. The water insulation layer, thermal insulation performance, such as freeze-thaw damage. At this time, the impact of the scope of the heat preservation material replacement, re construction. Then, if the insulation layer and wall have been cracking, we should use glue, grouting (epoxy resin) and other practices to plug the gap. Insulation materials are loose, and reinforcement measures such as studs. Replacement of insulation materials and large surface materials are often not bonded, encryption reinforcement measures should be taken.
Surface treatment. Construction surface layer. Usually hang wire mesh, or glass fiber cloth and so on to strengthen the network, wipe anti crack mortar, re construction of the finish layer.
