Advantages of using polyurethane sealing rockwool sandwich panels for roofing and cladding

Against the backdrop of a surge in demand for green buildings and energy-saving renovations, polyurethane sealing rockwool sandwich panels have become an ideal choice for roofing and building cladding projects due to its outstanding performance. As a leading sandwich panel supplier in China, Yirong Sandwich Panel Supplier continues to provide high-performance insulation and fire prevention solutions to global customers with advanced production processes and strict quality control systems.

Five core advantages of polyurethane sealing rockwool sandwich panels

Polyurethane edge sealing rock wool panel is based on rock wool core material and forms a seamless insulation layer through polyurethane foam edge sealing technology. Its advantages far exceed traditional boards:

A-level fire resistance performance

Rock wool core material is an inorganic non combustible material, combined with polyurethane edge sealing technology, with a fire rating of A (GB8624 standard), which can effectively block the spread of fire and meet the strict fire protection requirements of high-rise buildings and industrial plants.

Ultra low thermal conductivity

The thermal conductivity of the board is only 0.022W/(㎡· K), and the insulation performance is improved by 40% compared to traditional EPS boards, helping enterprises reduce energy consumption costs.

Waterproof and moisture-proof performance

Polyurethane edge sealing forms a dense protective layer with water absorption<0.5%. Combined with double-sided color coated steel plate, it can resist extreme weather such as rainstorm and snow melting, and is suitable for roof engineering in wet and rainy areas.

Lightweight and high-strength structure

The surface density of the board is only 45-60kg/㎡, with a bending strength of ≥ 1500N/m ², combining lightweight and high load-bearing characteristics, significantly reducing roof load pressure.

Green, environmentally friendly, and sustainable

Rock wool can be 100% recycled and its carbon emissions during production are reduced by 35% compared to traditional boards, meeting LEED and BREEAM certification standards.

Application scenarios of polyurethane sealing rockwool sandwich panels in roofing and cladding

Industrial plants and logistics warehousing

In large-span steel structure factories, polyurethane sealing rockwool sandwich panels can achieve a design without cold bridges, avoiding corrosion caused by condensed water and extending the building's lifespan.

Commercial building roof renovation

Thin design (thickness 50-100mm) eliminates the need to dismantle the original structure and directly covers the old roof, reducing construction time by 50% and overall cost by 30%.

Cold storage insulation system

Ultra low thermal conductivity and seamless edge sealing process ensure that the temperature fluctuation of the cold storage is ≤ ± 0.5 ℃, and the energy-saving efficiency is increased by 25%.

Core considerations for selecting sandwich panel suppliers
