RMS Board

Trilite® RMS Board is manufactured from a mixture of natural occurring mineral ores with high purity and highest quality reinforce with multiple layers of platinum strength glassfiberglass mesh. A Fireproof, Non-combustible, Category A board. It can be use for a wide range of applications both internal and external. It can achieve as high as 4 hours fire rating given the correct installation. RMS Board have very limited moisture absorption from air humidity, compared to normal MgO boards, the board does not contain any chloride ion (salt), resulting in corrosion of screws – nails – windows etc. The board can absorb and release moisture an unlimited number of times, without changes in the original board’s strength properties. The board is vapour permeable and insulation can be mounted directly on the backside, when used in ventilated constructions with closed vapour barrier.
  • Fireproof , Green Construction
  • Silica free and Chloride ion free
  • Will not rot or decay in humid environment
  • Resistant to termites, mold, fungus, mildew and insects

Application Areas of RMS Board

  • In combination with insulation materials such as EPS, XPS, Polyurethane foam, Rockwool, Glasswool, Fiberglass for superior sound, heat and fire insulation of partition walls and sandwich panels. Ideal for pre- fabricated light steel buildings and constructions.
  • For areas where you need the best water and moisture protection.
  • For furniture and decoration manufacturing (fireproof doors, counters, cabinets, safe deposits boxes, etc…)
  • For all interiors and exterior kinds of facings, linings, ceilings, raised flooring, underlayment, render backing among all others.
  • For all applications needing the best heat, fire, termite, mold, mildew protection.

Easy to Finish

RMS Board smooth side is ready to take all kinds of wall finishing such as paint, textures, stucco, render coatings, wallpapers. Rough back side is ideal for wall adhesives to stick with tiles, granites, and other lamination materials.

Safe to Use

RMS Board is an inert product qualifies for use in hyper-allergenic and clean room applications. It is non-toxic, free from any kinds of materials hazardous to human health or to the environment. It has been certified as class M1 safe product in Finland.

Easy Installation

RMS Board is engineered for strength, can be use for all forms of construction from wooden frame, metal frame and SIP panel assemblies. Easily cut with circular or reciprocating saws. It can be installed using nails, screws or staples.

TRILITE® RMS Board was tested by renowned Swedish SP laboratory for its hygroscopic moisture movement in comparision with 2 other MgO boards in 12mm thickness. The boards were conditioned in a climate chamber with a temperature of 20°C and 95% RH ( relative humidity). Visual finding results : After 42 days, no water was release or seen for the TRILITE RMS boards, while reference MgO sample#1 from factory A , started releasing water after 12 days, and MgO sample#2 from factory B started releasing water after 2 days.
