Board-form heat-insulation/sound-absorption material


Nichias offers two types of MG BOARD: a JIS1 product (MG BOARD 080) and a JIS2 product (MG BOARD 120), which are made by adding a thermosetting resin to rock wool as a binder and molding it into a board. For the surface materials of MG BOARD 080, Nichias offers adhesive aluminum glass cloth (ALGC) and glass cloth (GC) that is affixed flat on top and around the edges.

Belt-shaped thermal insulation materials


MG BELT is made by cutting MG BOARD into strips and reinforcing it with cheesecloth.
The fibers stand upright in the thickness direction, and so it has excellent flexibility and is easy to wrap around pipes and circular ducts. Nichias’ product lineup also includes a cheesecloth-affixed product and an ALGC-decorated product.

Blanket-form heat-insulation/sound-absorption material


MG WIRED BLANKET is a product that is made by fixing hexagonal wire mesh to one side of an MG BOARD with iron wire and rolling it up into a roll.
It has excellent workability and can be installed easily onto complex parts and curved surfaces. It is also useful as an additional heat insulation material for added thickness.

Rock wool pipe heat-insulation material


MG MIGHTY COVER is a roll of lightweight heat insulation material that is not susceptible to bending and has excellent thermal insulation, heat resistance, and non-flammable properties.
It has low levels of halogen and so it is excellent at preventing stress and corrosion cracks in stainless steel.

Decorated rock wool heat-insulation material

MG Decorated heat-insulation material

MG Decorated heat-insulation material is a product that is made by affixing ALGC or ALK on the surface of an MG product.
It comes complete with an outer material, so the finish is aesthetically pleasing and it is easy to install.

Decorated rock wool sound-absorption material

MG Decorated accoustic material

MG Decorated acoustic material is a sound-absorption material that is finished by adhering glass cloth around all sides of MG BOARD.
It is a product suitable for indoor sound absorption such as in underground machine rooms.

Kitchen exhaust duct fire-proofing material


TOMBO™ No. 4520-S

CERACOVER-S is lightweight fireproof material for ducts. It is not susceptible to bending and has excellent thermal insulation, heat resistance, and non-flammable properties.

Textile product


TOMBO™ No. 5685-A/-B/-C/-D/-E

FINEFLEX BIO textile products are cloths, tapes, cords, and ropes manufactured by mixing a small number of organic fibers with silica-magnesia-calcia-based alkali earth silicate (AES) wool and using the same method as general textile products.

Board-form heat-insulation material


TOMBO™ No. 4350

ROSLIM BOARD H and GH are high performance heat-insulation materials that have better thermal insulation than still air and top-class workability and handling.
ROSLIM Board GH won the 2015 Energy Conservation Grand Prize

General purpose heat insulation sheet


TOMBO™ No. 6702

NA MILLBOARD is a sheet made by mixing a slight amount of organic binder material with the main component of inorganic minerals before manufacturing it into a sheet form. It is a product with low thermal conductivity and excellent heat resistance (800°C).

Heat-expandable and fire-resistant sheet


TOMBO™ No. 6760-A

VERMOFLEX is a heat-expanding fireproof sheet that is made by mixing a heat-expandable inorganic material and small amounts of organic and inorganic binders with alkali earth silicate (AES) wool, and then manufacturing it into a sheet form. Its thickness expands by about three-fold when heated (when heated without a load).

Thin lagging glass cloth


TOMBO™ No. 8200

MARINETEX is a lagging cloth and tape for thermal insulation applications, made by weaving ultra-fine glass fiber with bulky yarn and subjecting it to repeated special treatment to eliminate the prickling sensation of the glass.
It provides excellent thermal insulation and is flexible and stretchy, making it suitable for bonding and sewing. It can be easily installed even in the most complicated of places.
