2 Product Characteristics

colorgerm product details

l New generation of interlaced dual-support joint for super strong wind resistance, air tightness, and zero thermal bridge conduction.

l Continuous line for high-efficiency production.

l Closed cavity to prevent water seepage, watertight & airtight.

l Prefabricated foam, edge sealed with PVC + aluminum foil, more waterproof and economical.

l PU edge sealing to prevent the core material from strength reduction due to moisture absorption, and at the same time, the thermal conductivity is quite low, thereby a more durable insulation performance.

colorgerm product advatages

The color gem adopts a prefabricated four-sided protective modular structure, which is structurally waterproof, air-tight, and fully and effectively protects the core material to avoid water ingress due to poor sealing. The integrated design avoids cumbersome processes such as multi-layer materials and multi-layer construction.

6 Product Knowledges

Comparison between traditional stone installation and Color Gem installation

Comparison between traditional stone installation and Color Gem installation

The traditional stone curtain wall construction is cumbersome, relying on labor, the cost is relatively large, and the pollution is serious.

Improve the thermal insulation performance, the board is as flat as a mirror, shorten the construction period to avoid on-site garbage, facilitate recycling and maintenance, and reduce the dependence of engineering quality on labor.
