Rock wool boards are widely used in energy-saving projects for building exterior walls due to their excellent thermal insulation performance and dimensional stability. Rock wool is made from basalt and other minerals melted at high temperatures and then fiberized. It features structural stability and resistance to deformation, making it suitable for long-term building exterior insulation systems.

In exterior wall insulation projects, rock wool boards effectively reduce heat loss from the wall, improving building energy efficiency. They also provide good sound insulation, contributing to improved indoor environmental quality. Their relatively high density and strength ensure stability during installation and anchoring, reducing the risk of later detachment.

During construction, ensure the substrate is flat and apply adhesive as required. Lay the insulation boards from bottom to top, ensuring tight joints without significant gaps. After installation, timely anchoring and finishing layer application are necessary to guarantee the overall performance of the insulation system. Proper selection of rock wool density and thickness ensures the energy-saving effect and service life of the project.
