Release time:

2023-05-22 17:06

Exterior wall insulation panels can be used independently for wall insulation via mechanical anchoring, or they can be combined with other insulation materials to achieve exterior wall thermal performance. The joints between panels and their connections to the main structure are installed using a unique tongue‑and‑groove interlocking and anchoring system. An external insulation system is formed through corner profiles, connecting elements, edge trim, window reveals, decorative moldings, and similar components; this system encompasses both joint‑anchoring methods and filled‑composite approaches.

　　System Features:

 

　　1. Installation may be carried out using mechanical anchoring, filling‑and‑reinforcement methods, or a light steel framing system.

 

　　2. The panel joints and end tongue-and-groove connections are securely fastened and watertight; all specialized accessories for various installation configurations are provided, ensuring the system’s safety.

 

　　3. Prevent thermal bridges; the exterior finish should be crack‑free, non‑delaminating, non‑absorbent, and quick‑drying. In northern regions, it must resist freeze–thaw cycles, while in southern regions, the finish should be resistant to mold and mildew.

 

　　4. The structural system shall have a service life of no less than 50 years, and the finish metal coating shall have a service life of no less than 20 years.

 

　　5. Dry‑process construction is not subject to seasonal or climatic constraints; for exterior walls in existing building renovations, no preparatory treatment is required, and the wall panels can be reused or recycled after removal.

 

　　6. Meet the 65% energy-saving target.

 

　　7. Colored aluminum alloy (or other colored metal sheets) is roll‑pressed to create various embossed and debossed textures, which not only enhance texture and surface strength but also improve resistance to thermal expansion and contraction.

 

　　Scope of Application for Exterior Wall Insulation Boards

 

　　1. Suitable for exterior wall external thermal insulation and decorative systems in residential and public buildings. It is applicable to both new construction and energy‑saving retrofits of existing buildings.

 

　　2. Enclosing walls of frame‑structure buildings.

 

　　3. This system is suitable for thermal insulation and decorative renovation of both interior and exterior walls in existing buildings, as well as for the envelope walls of villas and low- to mid-rise structures.

 

　　4. Suitable for extremely cold regions, cold regions, areas with hot summers and cold winters, and areas with hot summers and mild winters.

Construction Procedures and Precautions for Rubber Powder–Polystyrene Granule Systems

1. The rubber powder–polystyrene bead insulation mortar consists of rubber powder and polystyrene beads, which are packaged separately in bags. When used, the two components are mixed with water according to a specified ratio (rubber powder to water: 1:2). This material should be mixed as needed and applied within 4 hours.

Characteristics and Key Construction Points of Polymer-Bonded Mortar

Many customers do not fully understand the characteristics and key construction considerations of polymer‑bonded mortar. In this issue, a polymer‑bonded mortar manufacturer from Shandong will share with you the distinctive features of our products.

What are the main properties of graphite polystyrene boards?

Graphite‑polystyrene insulation boards, EPS polystyrene boards, and mechanically bonded rock wool mortar composite panels. The hydrophobic rock wool board serves as the thermal insulation layer, which is anchored to the base wall using a combined adhesive‑and‑mechanical fastening system. It comprises a finishing coat made of skim coat mortar and fiberglass mesh reinforcement, topped with either a decorative mortar finish or a paint coating, forming an A‑class non‑combustible building energy‑saving insulation system.
