2 Product Characteristics:

CASSETTE product details

High fire rating

-Adopt high-density water-repellent rock wool with Class A fire rating.

-The foam sealing material is flame-retardant and fire-resistant, with great  weatherability.

Fabricated structure

-Modular design for a prefabricated system with high prefabrication  precision in the factory.

-Modular installation, rapid construction, environmentally friendly and  pollution-free.

Excellent thermal insulation

-Multi-cavity airtight structure is formed at the joint of the PVC profile, while  the broken bridge structure takes into account of both the heat preservation  and insulation.

-The broken bridge structure without penetrating screws, as well as the  non-penetrating installation method, ensures the integrity of the thermal  insulation layer and greatly improves the thermal insulation performance.

-High-density thermal insulation, fireproof and water-repellent rock wool for  better thermal insulation performance.

CASSETTE product characteristics

Ultra-flat Surface

-When deployed horizontally, each panel transmits its stress independently to avoid  squeezing and deformation of the panel at the joint and improve the flatness after  installation. The F-type fastener adopts a sliding structure, which prevents the deformation  caused by indoor temperature difference between the panel and the structure, thus  keeping the building surface flat enduringly.

-The fixing method is upgraded from the point contact of the screw head to the surface  contact of the fastener, so that the stress is uniform and the system reliable.

Waterproof performance

-The joint end is designed scientifically to reduce water seepage.

-The twisty joint increases the waterproof performance.

-The double-layer slow-rebound PVC foam provides a reliable elastic sealing effect, as well  as great water tightness.

Service Life Guarantee

-Non-penetrating panel installation can prevent the screws from wearing that may cause  fatigue damage to the holes and joints.

-The broken bridge structure without screw penetration avoids condensation and keeps the  internal structure of the building dry.

-The proprietary "WISKIND" fasteners improve the surface hardness and wear resistance  through the carburizing process, ensuring the safety and improve the service life of the building.

-The surface of the F buckle is anodized for aesthetics and durability.
