Exterior Wall Rock Wool Insulation Board Rock wool board, also known as rock wool thermal insulation decorative board, is an inorganic fiber board made of basalt as the main raw material through high temperature melting processing. It was successfully tested in June, 1981. Rock wool board is a new type of thermal insulation, flame-proof and sound-absorbing material.

※ Various types of gas springs: Compressed gas spring (YQ), Liftable lockable gas spring (SKQ), Angle adjustable lockable gas spring (JKQ), Balanced gas spring (PQ), Stretch gas spring (LQ), Damper (ZQ)
※ The piston rod diameter, cylinder outer diameter, stroke, and extension length are in millimeters (mm), and the minimum extension force is in Newtons (N).
※ Connector type code: single piece (O), binaural (U), monaural (L), ball hinge (B), thread (M), taper (S)
※ Marking example: The diameter of the piston rod of the compressed gas spring is 10mm, the outer diameter of the cylinder is 22mm, the stroke is 260mm, the extension length is 630mm, the piston rod end joint is monolithic, the cylinder end joint is ball joint type, the minimum extension The force is 380N.
Marked as: YQ10/22-260-630(OB)380
The artificial inorganic fiber made of rock wool board by high temperature melting process has the characteristics of light weight, small thermal conductivity, heat absorption and incombustibility. The initial development is a common type of application in construction, which is mostly used in industrial buildings. It should meet the requirements of "Application Types and Basic Requirements of Building Thermal Insulation Materials". Rock wool is a kind of external insulation material. When the market share of 90% of the organic thermal insulation materials is stagnant, rock wool, as an inorganic thermal insulation material for exterior wall, has ushered in an unprecedented market opportunity.
