Features/Advantages:

Fire resistance: The rock wool core material is a non-combustible material with a sintering temperature of over 1000C, which can effectively block the spread of the flame in a fire and minimize the fire.

Insulation and energy saving: rock wool has low thermal conductivity (λ = 0.043w/m·k), and good thermal insulation performance. Excellent node design ensures sealing performance and thermal insulation effect.

sound insulation: sound insulation ≥ 30dB, effectively reducing the interference of external noise.

Water tightness/air tightness: The unique interlocking joint between the plates prevents the intrusion of water: The end connection of the plates is sealed inside to maintain good air tightness.

Sturdy and durable: High-quality rock wool material with high water repellency, supplemented by rigid polyurethane foam filling on both sides of the tongue and groove, enhances the overall strength and makes the building more durable and stable.

Beautiful façade: screw hidden node design, high flatness of the board surface, rich color of the paint coating, long-lasting color.

 

What is the difference between polyurethane edge-sealed rock wool panel and ordinary rock wool panel?
Polyurethane rock wool board, also known as polyurethane material side-sealed rock wool insulation board, flexibly utilizes the thermal insulation properties of polyurethane materials and the fire safety properties of rock wool boards. It is a new sandwich panel integrating thermal insulation and fire safety.A. Heat transfer coefficient: Polyurethane material side sealing rock wool insulation panel: ≤0.025W/m-·k-General rock wool insulation panel: ≤0.043W/m·kB. Tensile strength: Polyurethane material side sealing rock wool insulation board: ≥150KPA-General rock wool insulation board: ≥100KPAC. Flame retardant grade: Pu edge-sealed rock wool board: Class A non-combustible - General rock wool insulation board: Class A non-combustibleD. Relative density:PU edge-sealed rock wool insulation board: 80-120KG/m³-General rock wool insulation board: 40-60KG/m³E.airtight moisture resistance: PU edge-sealed rock wool thermal insulation panel:Polyurethane material double-sided sealing rock wool sandwich panel adopts the production line processing technology, and then uses the excellent moisture resistance of polyurethane products to get rid of the defect of easy moisture absorption and deliquescence of rock wool panels, and reasonably increases the service life of the product in terms of process performance. General rock wool insulation panel: There are no edges on both sides, and water is very easy to penetrate into the panel to cause deformation of the panel.F.plate-shaped steel bar lap: PU edge-sealed rock wool thermal insulation panel: built-in steel bar lap joint, reasonable increase of service life - general rock wool thermal insulation panel: open nail type installation, exposed external nails are easy to corrode G, environmental protection characteristics. PU-wrapped rock wool insulation panel: Polyurethane material edging reasonably avoids the exposure of the rock wool board-General rock wool insulation board: No urethane material edging causes the rock wool panel to be exposed.
