What is mgo sip problem? Mgo sip are composite of 1/2 layer of magnesium oxide sheathing on both side, EPS/XPS work as core. It is fireproof, insert proof, moisture proof, mold proof and sound proof. However there are some home owners complaint: 1, corrosive to steel frame/metal screw, effect structural safety 2,chloride absorb moisture will damp insulation materials and wall paper 3,low impact resistant and low screw holding strength, difficult to repair once it is damaged Please kindly note: 1,Many mgo board contains high volume of chloride >5%, do not suggest to use for steel frame system 2,Don't use mgo [...]

What is eps mgo board? Rockmax eps mgo board is similar to Permabase and Dura backer board, design for moistureproof substrate.but made of magnesium oxysulfate cement and eps. It is lighter weight,fireproof,moisture,easily cut and screw faster.Our eps mgo board has superior impact resistant. 1.20 years non corrosive warranty 2,safe material tested to EN reach 3.Waterproof coating surface 4. Durability tested to EN 12467 https://youtu.be/PlF7ix9m9nI

Today, we'd like to discuss the problem of magnesium oxide board joint crack. What is mgo board? A cost effective fire rated inorganic binded reinforced by glass mesh and plant fiber, roll into a flat sheet,that can be use for strucutal and non stuctural wall and subfloor. Why mgo board joint crack more requently? Moisture content Gypsum board and fiber cement board have mature drying facility, moisture may 10-12% when export.However many mgo board supplier don't have moisture control facility,result in uneven and excessive moisture when export,moisture may 10-25%. Dry shrinkage The dimension change of gypsum board and fiber cement [...]

"What's difference between mgo board and fiber cement board?" A frequent question asked by many customers. Before say something, we should think about which product category does mgo board exactly belongs to? In my point of view, mgo board belongs to CBPB - cement bonded wood particle board which has been listed in building materials category in both Europe and America. mgo board made some upgrates: 1,mgo board use magnesium oxide cement as binder,it has lighter weight and better fireproof than portland cement. 2,mgo board composite multi-layers of glass mesh fiber, impact resistant and flexibility increased. 3,mgo board is entirely [...]

MAGNESIUM SULFATE BOARD Magnesium sulfate board is new technical chloride free mgo board, with exceptional fireproof, flexibility and workability which is competitive product for exterior substrate, structural sheathing, sub flooring, fireproof decorative wall base board and fireproof laminated flooring base board. Each application has corresponding standard of physical and durability performance. For cladding and render system recommend to use high density fiber cement board.

Someone said “Mgo board is the wrost building material in decades” There are couple of reasons: 1,Chloride mgo board it's corrosive and damp wall 2,User treat mgo as fiber cement board,use it as cladding and render without durability test and system evaluation 3,Low strength mgo board use as shear wall   is it ending of mgo board? Due to hundreds of scientists' efforts,magnesium sulfate board get rid of chloride ion entirely. Those Germany,Italian,Canadian,Chinese scientists carry on researching magnesium sulfate cement for 5 reasons 1, Magnesium sulfate board is cost competitive for interior and exterior substrate, fireproof and moisture resistant 2, High bending [...]
