Building Material Rock Wool Sandwich Panels Exterior wall panels for mobile home and luxury prefab house

Aspects

Advantages

Fire rating

* A non-combustible

Sound insulation

* Sound insulation noise reduction

Color

* Any color (usually blue)

Water proof

* Non-absorbent and anti-aging

Environment

* Biodegradable and environmental friendly

Acidity coefficient

* 1.4 ;  Reduce corrosion of metals

Differences with mineral cotton

* Mineral cotton's acidity coefficient is 1.1 lower than rock wool,  calcium oxide and magnesium oxide are higher than rock wool that has strong corrosion of metals. This is why  rock wool is better than mineral cotton.

Strength

* We will cut the whole piece of rock wool into same length, thick, and width rock wool stripes . Turn them  over for 90º to make the rock wool silk stand instead of flat . It increases the strength more . We  also  break the orderly arrangement of rock and stagger them in the same length. It may perfectly have more strength than ordinary rock wool sandwich panels.

Roof wave crest data

* Height : 42 mm. Space distance between two wave crest: 333 mm.

Effective width

* 1000 mm

Special design of each side

* Polyurethane are used in both sides in order to increase the insulation performance of rock wool sandwich panels. It improves air impermeabi  lity and water tightness between the two joint pieces.  It avoids cold bridge phenomenon . Furthermore It overcomes the occurrence of stripping of steel plate and core material at the junction of plate in the process of handling and installation.  So it is our new type rock wool sandwich panel and it avoids the disadvantage of poor air tightness of traditional rock wool sandwich board.

Surface appearance sorts

* Flat -F ; Square wave -S ; Water ripple-W;   Concave in water ripple-WC; Big wave -BW;  All around tongue-and-groove curtain wallboard--TG;  Ripplet--V8. All kinds of surfaces for your choosing.
