What is composite wood ceiling?

Composite wood plastic ceiling is a ceiling system built from a skeleton system, wood plastic panels (or wood plastic ceiling slats) along with accompanying accessories during the installation process, popularly used for outdoor spaces such as balconies, gardens, cafes, restaurants...

1. Skeletal system: Used to reinforce and stabilize the ceiling, usually made from sturdy, strong materials such as galvanized steel, etc.
2. Plastic wood paneling/ceiling plastic wood slats: Is the outer covering of the ceiling, made from Composite wood. Wood plastic panels form a closed ceiling system with panels tightly connected by yin and yang locking grooves. Wood plastic hanging slats have joints directly attached to specialized ribs, an open ceiling that brings uniqueness and ventilation.

Composite wood panels are the top choice for outdoor ceilings. Currently there are 2 types of wood plastic ceilings:

• 1 layer wood plastic: This type is mainly composed of wood powder (55-60%), plastic powder (30-35%), and 10% additives (1-layer fluted wood plastic panel is not recommended for ceiling cladding).
• ASA wood plastic (lightweight): Different structure with 20% wood powder, 60% PVC plastic, 10% additives, and especially 10% ASA coating. ASA coating helps increase the durability and weather resistance of the product.

In addition, this material also has natural colors like real wood (golden wood, coffee brown, red brown, dark gray, ...), bringing a luxurious and cozy beauty to every space.

4 popular types of outdoor composite wood ceilings

Through research from many reputable sources, Kosmos has compiled 4 popular types of outdoor ceilings made of composite wood:

• Ceiling with standard 1-layer wood plastic panel
• Ceiling with ASA coated wood plastic panels
• Ceiling with Polymer-coated wood plastic panels
• The ceiling is installed with plastic wooden slats (plastic wood ceiling slats).

Standard outdoor 1-layer wood plastic ceiling panel

Single-layer wood plastic ceiling panels (standard wood plastic ceiling panels) are made from 1 - 55% wood powder, 60 - 30% HDPE plastic, 35% additives, extruded in one piece, without surface coating.

ASA coated 2-layer wood plastic ceiling panels

This is an outdoor ceiling panel made from a mixture of wood powder and PVC plastic with the surface coated with ASA (Acrylonitrile Styrene Acrylate) plastic. Because ASA is a thermoplastic developed to replace ABS plastic, it has good weather resistance and is also used to cover roof tiles.

The product has a ratio of 20% wood powder, 60% PVC plastic, 10% additives, 10% ASA coating, so it is quite light but still ensures durability. The lifespan of 2-layer ASA-coated wood plastic panels is from 10 to 15 years, with a 5-year warranty.

2-layer polymer-coated wood plastic ceiling panels

Similar to standard outdoor wood plastic panels, 2-layer polymer-coated wood plastic panels (2-layer wood plastic panels) are made from 60% wood powder, 30% HDPE plastic, 10% additives and a polymer coating. This coating helps the product resist scratches better and prevents UV rays from fading.
