1. Construction preparation
1.1 Plastering the grass-roots level with 1: 3 waterproof cement mortar leveling the whole, to ensure that the deviation of base surface roughness is less than 3mm
1.2 In order to ensure the feasibility of construction, according to the actual situation. Firstly, rock wool board sample should be tested at the the external wall’s appropriate position, until passes the test and the qualified test report is issued, the large-area construction can only be carried out.
2. Security Technology Explanation
Before entering the construction site, the general contractor is responsible for the on-site safety technical personnel, to explain the security technology. Construction should be strictly accordance with safety and technical requirements.
3. Material preparation
When all raw materials enter the construction site, the relevant warranty information should be complete, promptly report to the supervision unit, after the correct acceptance, pile on the designated site
Advantages of rock wool insulation in the external wall construction :
♦ A1-level high temperature materials, good fire-proof effect, and not melt in 1000℃
♦ Low cost, cost-effective, suitable for large-scale use
♦ Noise insulation and reduction
♦ Non-toxic, non-asbestos, not harm human health, not release toxic fumes, can be used securely assured
♦ Excellent breathability, not corrosive to the metal materials and various structures in the building
