- For a higher sounf insulation values, we recommend the user to apply higher density mineral wool /rockwool / glassfibre wool in the cavity and leave a gap for sound transmission inside the core of the partition.
- Superior Moisture Resistance
- TRILITE will not rot nor physically deteriorate. It is also highly resistant to the effects of moisture. It arborbs moisture and retains its full strength upon drying without affecting the long-term performance of the board.
- Chemically Stable
- Boards are produced from natural, inorganic raw materials and the chemical reaction is irreversible, resulting in a chemically stable board that is hard yet flexible – a strong board that maintains its strength over time yet is easy to finish.
- Good Thermal Properties
- TRILITE boards has less ability to transmit heat and can be an efficient thermal insulant. The rated thermal conductivity of the boards are less than 0.139 W/mK.
- Resistant to Climatic Conditions
- Tested to many cycles of soaking, freezing, heeting (freeze/thaw test method). The board showed no signs of cracking, crumbling, nor any form of disintegration. For applications within normal specifications, the life span of the board is limited only by the durability of the supporting structures and the materials used in fixing.

- Superior Sound Insulation
- As your reference, the average rate of noise reduction between the frequencies of 100 Hz to 8000 Hz is 38dB for a partition of 93mm thickness with 9mm on each face. For higher sound insulation values, we recommend the user to apply higher density and thicker core of mineral wool, rockwool or glassfibre wool in the cavity and leave a gap for sound transmission inside the core of the partition or ceiling system.
- Green & Sustainable
TRILITE RMS board is a “low tech” and “energy friendly” product it is non-toxic. CO2 is high on the list of “greenhouse” gases, which are said to contribute to the global warming. Our production process is simple, energy efficient, and produces extremely few “greenhouse” gases. This aspect of our board as ‘green’/eco-friendly product, indicates a bright future. Unlike, for example, the gypsum based drywalls that produce thousands of tons of green house gases annually in the manufacturing and drying process, RMS board is naturally dried and cured with no chemicals or heating, eliminating the power intensive drying process. Magnesium Oxide, one of the main ingredient in the boards covers over 8% of the earth’s surface so the product is very sustainable too. An environmentally friendly construction material manufactured from naturally occurring minerals.
NO organic solvents
NO Toxic ingredients
NO heavy metal salts
NO formaldehyde emission

Handling & Storage
Other Handling Instructions
- Boards should be slided sideways when lifted from pallets.
- Boards are supplied in packs on wooden pallets to permit safe handling by forklift trucks.
- Boards must be allowed to dry ( when becomes wet) prior to fixing, installing or painting.
- If outside, a protective plastic sheet must protect the sheets from getting rain and the elements.
- Boards must never be piled up more than 3 pallets on top of each other.
Fixing & Jointing
- Can be easily cut using a normal saw, fret saw or an electric tool. When large quantities of the boards are to be cut, the use of a circular hand saw is advisable.
- Use masonry drills to countersink or drill screws. Use low/high speed drills for better results. Place the board under the drilling location for a clean hole. Do not use hammer action.
- Planing and Sanding
- The edge can be planed or smoothed with a surform, rasp or file. Use cponventional papers for sanding.
- Ludox RMS are suitable for fixing to both timber and metal framing. Studs are recommended to be placed at 407mm centers. Enough gap in between joints of 2 boards is required, which is normally at 4mm. Be sure to handle the fillings of the gaps for partitions. Before filling, each gap must be clean and removed of all dusts (including steel brush), otherwise the contact point between the sealants and the board is separated without bonding together and may result in surface cracking. Should be constructed according to local building regulations & practice.
- For screwing, it is recommended to use self drilling, self countersunk screw in stainless steel. Screw diameter should be from 3.5~4.2mm, length should be 2.5 to 3 times the panel thickness. Fixings at 200mm nominal centers, perimeter of panel fixings should be 10~15mm from the edge of the board and all edges should coincide with support structures. Thinner boards can be stapled with 16 gauge, 6mm crown x 25mm long rust-proof staples.
- Can be easily cut either longitudinally or traversely. A cut should be made on the face side of the board by means of a cutter or a knife. A line may be ruled prior to cutting. The rule can be drawn down the board at the required distance and can be scored with the knife at the end of the rule. The boards should then be pressed with both hands, cut and snap over a straight edge. For smooth and clean cut, use a circular saw (at least 120 carbide teeth) and set the speed above 3000 rpm.
- Can be manual or power nailing using a flat headed, preferably stainless steel nail. Diameter should be 2.2 or 3.1mm, length 3 to 3.5 times the panel thickness. For power nailing, tools should be set to 3-4 bars and then finely adjusted to achieve required penetration. It is essential to position the boards steadily against the background structure.
- On timber or steel for 6mm, 8mm and 9mm supports should be 400 centers. for 10mm, 12mm at 600 centers.
