Instructions for installing 1-layer OP148 wood plastic ceiling panels under poly, glass, and corrugated iron roofs
OP1 flat profile 148-layer wood plastic panel when constructing ceiling cladding under poly, glass, and corrugated iron roofs has 2 main cases including:
- Horizontal ceiling panel, vertical bar installation
- Vertical ceiling panel, horizontal bar installation.
The 1-layer wood plastic panel OP148 weighs from 3,5kg/bar - 5,2kg/bar, so it needs to be reinforced on a sturdy frame system to ensure safety for users. The distance between the wood plastic ceiling OP148 and the poly, glass, and corrugated iron roof 300 - 500mm, it is mandatory to install an additional layer of insulation between the ceiling and the roof.

| 148 x 21 x 3000mm | 5kg/bar ±5% | |
| 3DOP148 (Kosmos) | 148 x 21 x 3000mm | 5kg/bar ±5% |
| GOP148 (Galawood) | 148 x 21 x 3000mm | 5kg/bar ±5% |
| G3DOP148 (Galawood) | 148 x 21 x 3000mm | 5,2kg/bar ±5% |
In addition, the construction area of the ceiling for 148-layer OP1 wood plastic panel must be ensured. width ≤6m and height ≤3mIf the construction area is larger, please use 2-layer ASA-coated flat wood-plastic panels (OP113X16, OP140X12) for construction - This is a lightweight material, a solution for wall cladding, ceiling cladding, and partition cladding for large spaces.
Step 1: Prepare construction materials and tools
Supplies
You need to prepare the following 7 materials to install ceiling panels under poly, glass, and corrugated iron roofs with 148-layer OP1 panels:
- Bar (stainless steel, galvanized steel) size ≥25x25mm and thickness ≥1.2mm
- Flat profile 1-layer wood plastic panel (OP148, 3DOP148, GOP148, G3DOP148)
- Wood plastic V-shaped strip (V60X60, V40X60, GV40X60)
- Insulation materials (silver foam 5mm or more, corrugated iron, plastic foam)
- Stainless steel screw with pee tail
- Copper nail
- Kosmos exterior glue.
Tool
8 tools needed to prepare for constructing OP1 flat-shaped 148-layer wood-plastic ceiling panels include:
- Angle cutter, drill, welding machine, laser machine
- Tape measure, angle ruler
- Folding ladder
- Nail gun.
Step 2: Construct additional frame system to install under poly, glass, and corrugated iron roofs.
Construct a new skeleton layer (stainless steel or galvanized steel bars of size ≥25x25mm, thickness ≥1.2mm). At the connection of 2 panels, 2 double ribs are needed with a distance of 5mm. The OP1 148-layer wood-plastic ceiling frame under glass, corrugated iron, and poly roofs requires the size width ≤6m and height ≤3m.
| Vertical ceiling panels Using a welding machine, weld the ribs firmly with the distance between the ribs. ≤25cm horizontally, the weld needs to be smoothed and painted with anti-rust paint. | Horizontal ceiling tiles Using a welding machine, weld the ribs firmly with the distance between the ribs. ≤25cm vertically, the weld needs to be smoothed and painted with anti-rust paint. |
Step 3: Install insulation
After having a new skeleton system, the Customer installs a layer of insulation material (can use silver foam 5mm thick or more, heat-insulating corrugated iron or plastic foam) on top of this skeleton and fixes it with glue or stainless steel screws.
Step 4: Weld the frame and insulation material onto the glass, corrugated iron, and poly roof.
Weld the new frame and insulation material to the roof frame of corrugated iron, glass, and poly. The welds need to be smoothed and painted with anti-rust paint. The distance between the wooden plastic ceiling frame and the glass, corrugated iron, or poly roof is required to be 300 – 500mm and the frame should have a slight outward slope of 2 – 3%.
OP1 148-layer wood plastic panel has an expansion rate of 5 - 10%, so the distance between the frame and the wall (if any) is 7 - 10mm, this is a safe distance for the frame and OP148 panel to expand.
Step 5: Install the OP1 single-layer wood plastic panel onto the frame
5 steps to install wood plastic panel OP148 Vertical ceiling panels on the skeleton:
1. Kosmos exterior glue into the frame before installing the panel.
2. Installation hem The first wood plastic panel is close to the frame (as shown in the picture), the groove is facing the frame (install the panel from left to right or from right to left depending on the installer).
Later pilot drill and screw with fish tail into the groove to fix the panel on the rib (the distance between the screw holes is equal to the distance between the ribs). ≤25cm).
3. Install the male groove of the second panel into the screwed negative groove of the first panel, proceed to drill a pilot hole and screw the fishtail stainless steel screws to Fix the second panel to the rib at the negative groove.
4. Repeat step 3 for each OP1 148-layer panel until the end of the ceiling.
5. The open area between the glass, corrugated iron, poly roof and the wood-plastic ceiling will use OP148 panels for similar construction (or use 1-layer wood-plastic multi-purpose bars).
Kosmos recommends
At the joint position, the panels need to be placed on double ribs, the distance between 2 double ribs is 5mm and the distance between 2 joints of 1-layer OP148 wood-plastic panel is 5mm.
4 steps to install wood plastic panel OP148 horizontal ceiling on the skeleton:
1. Kosmos exterior glue into the frame before installing the panel.
2. Installation hem The first wood plastic panel is next to the wall, negative facing outwards (Kosmos recommends installing the panels from the inside out). The panels and the frame need to leave a gap of 7 – 10mm from the wall.
Later, pilot drill and stainless steel screws fish tail into the groove to fix the panel on the rib (the distance between the screw holes is equal to the distance between the ribs). ≤25cm)
3. Install the male groove of the second panel into the screwed negative groove of the first panel. Drill pilot holes and screw the stainless steel screws to fix the second panel onto the crossbar at the negative groove.
4. Repeat step 3 for each panel until the ceiling is full.
5. The open area between the glass, corrugated iron, poly roof and the wood-plastic ceiling will use OP148 panels for similar construction (or use 1-layer wood-plastic multi-purpose bars).
Kosmos recommends
At the joint position, the panels need to be placed on double ribs, the distance between 2 double ribs is 5mm and the distance between 2 joints of 1-layer OP148 wood-plastic panel is 5mm.
Note: In case the installation area receives direct and frequent sunlight, Kosmos recommends using smooth grain panels or 3D wood grain instead of 2D printed grain.
Step 6: Cover the edges of the panel with wood-plastic V-shaped strips and you're done.
There are 2 ways to use wood plastic V-shaped strips (V60X60, V40X60, GV40X60) cover the exposed edges of the OP148 end panels.
Option 1: Use Kosmos exterior glue and stainless steel screws to secure the V-shaped strip to cover the end edges of the OP148 panel. vertical/horizontal, screw hole spacing ≤35cm.
Note: Need to drill pilot holes before screwing into wood plastic V-shaped strips.
Option 2: Use Kosmos exterior glue and copper nails to secure the V-shaped strip to cover the end edges of the 148-layer OP1 panel. vertical/horizontal with nail hole spacing ≤10cm.
*Kosmos recommends
To ensure the wood plastic ceiling is durable and beautiful, rainwater does not accumulate inside and cause mold, you need to install a "water pipe" to ensure the durability of the ceiling.
Waterline is a line usually raised with mortar on balconies and loggias. Can be used water cut off splint/replaceable water hook. This detail prevents rainwater from flowing back into the ceiling.
In addition to cladding the ceiling under poly, glass, and corrugated iron roofs, OP1 148-layer wood plastic can also be used by customers. OP148 wood plastic panel for horizontal and vertical wall cladding.
