To achieve a maintenance zero defect furniture, please follow the video mentioning about the working with Indowud nfc.
Indowud nfc is a homogeneous product and hence requires proper constructive grid support (frames, channels, etc made of metal tube) to avoid deformations
Suggested grid square for panelling
Maximum Support Distance
| Thickness of Indowud NFC board (in mm) | 6 | 8 | 12 | 15 | 16 | 18 | 20 | 25 |
|---|---|---|---|---|---|---|---|---|
| Neo (in mm) 625+ Kg/CBM | 150 | 200 | 250 | 300 | 300 | 350 | 400 | 500 |
| Create (in mm) 725+ Kg/CBM | 200 | 250 | 300 | 350 | 350 | 400 | 450 | 550 |
| Build (in mm) 825+ Kg/CBM | 250 | 350 | 450 | 550 | 550 | 600 | 650 | 750 |
For ceiling, use 12mm or higher thickness board with suggested grid square support of 300mm for create or build and 200mm for neo.
PU paint & Polish
Do not use NC putty. Ensure that solvent/epoxy-based sealer, PU filler is used. Do not pour water on the raw board before closure of the micro pores all around. Ensure that the micro pores at all sides (surface and edge) are closed with epoxy/solvent-based sealer/primer.
Wardrobe/Cabinet Shutters
In order to avoid bowing or deformation, paste veneer/laminate on both sides before fixing shutter. We suggest to cover the edges with a suitable lipping/edge band. Ensure similar panel is pasted on both sides for similar balancing. In case of varnish/polish/PU paint, cover the micro pores with epoxy/solvent sealer and then fix the shutter. Use hinges at every 300-350mm and magnetic ball catch at top and bottom. Use of stiffener/straighter is recommended. For sliding shutters, ensure proper framing on all four sides with necessary stiffeners.
Suggested Adhesive
NFC-GLU, PUR, Heatx, WP1, Probond, Plastilok, Relam.
Drying time may vary depending on atmospheric conditions
For any glue, we advise to test on a small piece before applying on larger panels
Paneling
Leave min 12mm gap between wall and board for breathing
Leave 5mm gap on ceiling and flooring for breathing and expansion/contraction
Leave a gap of 3 – 5 mm between two boards
Screwing
Use wide head, fully threaded, three times long of the board thickness. Gluing at the joinery is suggested for better strength. Screwing should be slow and stop at the surface. Do not hammer and do not pull out the screw.
Ceiling
When using Indowud nfc Boards for ceiling beautification, it is imperative to follow advanced technical guidelines to ensure a secure, durable, and aesthetically superior installation. The following comprehensive recommendations will aid in achieving the best in class results:
1. Gravity Consideration and Fastening Method:
Gravitational Forces –Recognise and counteract the gravitational forces acting on ceiling-mounted Indowud nfc products.
Support- We suggest to use 12mm or higher thickness nfc product with a suggested grid support of 300mm x 300 for create and build and 200mm x 200mm for neo.
Fastening- Utilise wide head washer screws to secure the product to the ceiling. These screws offer a larger contact area, distributing the load more evenly and reducing the risk of detachment. Ensure that screws penetrate at least double of the thickness of the boards into the substructure for optimal holding strength.
Screw Placement- Place screws at intervals of no more than 300mm along the board edges and 400mm within the field of the boards to provide consistent support and prevent sagging.
2. Thermal Management for Outdoor Applications:
Heat Exposure- For ceiling applications exposed to direct sunlight, such as open-to-sky installations, the supporting mild steel (MS) substructure can absorb and retain heat, leading to thermal expansion and potential structural compromise.
Preventive Measures- Apply a heat-resistant rubber paint coating to the MS substructure. This thermal barrier reduces heat transfer, mitigating thermal expansion and protecting the integrity of the product.
Thermal Breaks- Incorporate thermal breaks within the substructure design to minimise heat conduction. Materials such as insulating foam strips or thermal pads can be placed between the metal substructure and the nfc board product.
3. Installation Technique:
Avoiding screw on porous surface: – Avoid fixing screws directly into the grooves or routed porous surface of nfc boards. This can compromise the structural integrity of the product due to porous nature of centre core.
Trimming and Shaping- Create a Z-shaped edge on the board’s perimeter before installation. This technique enhances alignment, stability, and aesthetic appeal.
Expansion Gap- Maintain a gap of 3mm to 6mm between boards to accommodate thermal expansion and contraction, preventing buckling or warping over time. Use spacer tools during installation to ensure consistent gap width.
Sealants and Adhesives- Use high-quality, UV-resistant sealants and adhesives specifically designed for nfc materials to ensure a durable bond and prevent moisture ingress.
Pre-drilling- Pre-drill screw holes to the appropriate diameter to prevent splitting and ensure precise screw placement.
4. Moisture Management:
Waterproofing: Apply a waterproof membrane or coating on the surfaces of the product against moisture ingress especially in high-humidity or coastal environments.
Ventilation: Ensure proper ventilation above the ceiling boards to allow for air circulation and prevent moisture buildup, which can lead to mold or mildew.
5. Structural Support:
Support Requirements-
Due to the gravitational pull, Indowud NFC boards require proper structural support tailored to the thickness and weight of the product. The substructure should be designed to bear the load effectively, considering both static and dynamic forces. This includes using adequately sized and spaced support beams or frames to distribute the weight evenly and prevent any sagging or deformation of the boards.
6. Additional Reinforcements:
Support Brackets: Incorporate additional support brackets or cross members in the substructure to enhance rigidity and distribute loads more effectively.
Edge Protection: Use edge protection profiles to safeguard the nfc boards from impact damage and to provide a clean, finished look.
By meticulously following these guidelines, one can achieve a ceiling installation with Indowud nfc boards that not only meets but exceeds industry standards, ensuring longevity, stability, and an impeccable aesthetic.
