Building Exterior Insulation Board

Core Working Principles

Building exterior insulation boards enhance building energy efficiency through the following mechanisms:

1. Blocking heat conduction and convection: Their dense internal closed-cell or fibrous structure effectively slows the direct flow of heat through the material and minimizes heat loss caused by air convection.

2. Eliminating thermal bridging: Acting as a continuous exterior insulation layer, the board covers highly conductive components—such as concrete or steel structures—thereby reducing heat loss through the building's structural elements.

3. Forming an air barrier: When properly installed, the insulation board creates a continuous air barrier that prevents air infiltration and exfiltration, helping to maintain stable indoor temperatures.

Core Advantages

1. Compatible with all common building structures: Brick-concrete, frame, light steel, and timber structures can all be installed directly without pre-treatment of the wall surface.

2. Insulation and decoration completed simultaneously: One process replaces the traditional four-step exterior wall process (external plastering + insulation board + mesh + paint or tiling).

3. Board itself is non-absorbent: The combination of metal substrate + closed-cell core material makes the entire board nearly non-absorbent; rainwater flows directly along the board surface, keeping the wall dry.

4. Good seismic performance: Lightweight (approximately 6 – 8kg/m²), it does not pose a risk of falling and causing injury during earthquakes due to wall shaking.

5. Convenient for retrofitting: For existing buildings, there is no need to move furniture; construction is carried out only on the exterior wall without affecting daily living.

Why Choose Jason Building Materials?

Jason Building Materials operates fully automated, precision production lines, with products certified by ISO9001 and authoritative international bodies such as SGS. Our prefabricated manufacturing eliminates common issues associated with traditional on-site wet-process facades, such as peeling, cracking, and color inconsistency, while ensuring precise, interlocking panel joints.

We offer comprehensive customization services, providing over a hundred textures and colors, and can manufacture products to exact specifications based on standard RAL color codes or architectural CAD drawings.

Our panels feature high-quality Al-Zn coated steel combined with PVDF (fluorocarbon) or HDP (high-durability) coatings. They utilize a 100% dry-installation method, increasing installation speed by more than 50% compared to traditional facade systems.

FAQ

Q1: Can Building Exterior Insulation Board be used indoors?

A1: Yes. When used for interior partition walls, thermal insulation is not the primary purpose. The advantages are: surface patterns provide direct decoration without the need for putty and paint, fast installation, and no dust pollution.

Q2: Do the panels require expansion joints?

A2: Yes. Expansion joints must be set every 6 – 8m or at structural deformation joints, with a joint width of 10 – 15mm, filled with weather-resistant sealant.

Q3: What if the board surface is scratched by sharp objects?

A3: Surface scratches do not affect function and can be treated with a color-matched touch-up pen. For deep scratches that penetrate the steel plate, it is recommended to replace the individual panel; the dry-hanging system supports single-panel removal and replacement.
